While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImproved Performance\u003c\/strong\u003e\u003cbr\u003e\nSuperior edge performance not only creates rounder, more pleasing stars, but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture.

EdgeHD 8 is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTrue Astrograph Quality\u003c\/strong\u003e\u003cbr\u003eMany optical designs that advertise themselves as \"astrographs\" actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImproved Performance\u003c\/strong\u003e\u003cbr\u003eSuperior edge performance not only creates rounder, more pleasing stars, but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture.

This incredibly fast f\/2.0 system is the perfect companion to today’s color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras. Thanks to its fast focal ratio and patented optical design, you can produce sharp, detailed images and, in many cases, skip the autoguider completely.

With the 8” RASA joining the lineup, a wider range of astroimagers can enjoy the benefits of the RASA design. It has many of the same thoughtfully designed features as its “big brother” RASA 11, including the integrated air-cooling system, internal filter mount, and sturdy CGE dovetail mounting bar.\u003c\/p\u003e\n\u003cp\u003ePurely designed for imaging, the 8” RASA cannot be used visually.

The 8” RASA’s relatively short 400mm focal length also lessens equatorial tracking demands. In many cases, autoguiding will not be required.

The telescope does not work with standard DSLR cameras. It is optimized for sensors with up to a 22mm diagonal, but performs well with sensors up to 32mm diagonal. The APS-C sized sensors used in many mirrorless cameras are a good choice. 42mm full frame sensors will also work, but performance will be poor at the edges of the sensor and field illumination will be reduced. Additionally, we do not recommend pairing RASA 8 with any camera body more than 4” in diameter.

The design consists of a Schmidt corrector, primary mirror, lens group, and optical window. The lens group contains 4 elements and utilizes rare-earth elements. Unlike many telescopes that only perform well over the visible spectrum (400-700nm), the 8” RASA’s optics are designed to perform over a wider spectral range, from 390-800nm. This allows more of the light emitted from the astronomical object to be sharply focused in the image.\u003c\/p\u003e\n\u003cp\u003eWith many imaging systems, adding an extra piece of flat glass such as a filter does not change optical performance. However, that is not the case with super-fast optical systems like the RASA. Our engineers addressed this by designing the RASA with a removeable optical window, so you can maintain peak optical performance if a filter is added or if a camera has its own optical window.

Therefore, you cannot look through the RASA 8 with your eyes because your head will block the light from entering the telescope. The RASA 8 is an astrograph designed specifically for deep-sky astronomical imaging.\u003cstrong\u003eQ: Why was the RASA 8 designed to have a camera mount at the front of the telescope?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eThe RASA 8 optical design uses a prime focus focal plane position in order to obtain its super-fast F\/2.0 focal ratio. This necessitates the camera having to be mounted at the front of the astrograph.\u003cstrong\u003eQ: Won’t the camera block the incoming light?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eThe RASA 8 optical design has its own central obstruction which is caused by the sub-aperture lens assembly at the front of the telescope. The lens assembly has an outer diameter of 93mm. If a camera’s body is smaller than this, it will not block any light from reaching the camera sensor. If the camera body is larger than this, then it will block some of the incoming light. As long as the camera body does not greatly exceed about 120mm diameter, the effect on images is negligible.\u003cstrong\u003eQ: What cameras can be used with the RASA 8?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eThe RASA 8 can be used with many astronomical CMOS and CCD cameras. It also works well with mirrorless digital cameras. Two key considerations are the size of the camera body (should not exceed about 120mm in diameter), and the camera’s backfocus distance (cannot exceed 25mm). Color or monochrome sensors can be used, although color sensors are easiest to use since the RASA 8 cannot accommodate a filter wheel (see question #7).\u003cstrong\u003eQ: Why can’t a DSLR be used with the RASA 8?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eThe body size of a DSLR is too large compared to the front aperture of the RASA 8, and therefore blocks too much of the incoming light. Also, the DSLR requires too much backfocus (55mm) for the RASA 8, so the camera sensor cannot be placed at the required location relative to the astrograph. For DSLR imaging, we recommend the RASA 11.\u003cstrong\u003eQ: What about camera cables in front of the optics?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eCamera cables which cross the front of the RASA 8 do not block much light and, don’t have a significant effect on images. To minimize any potential diffraction spike around the brightest stars, camera cables can be positioned to cross the aperture in a curved pattern, rather than a straight line.\u003cstrong\u003eQ: Will I need additional camera adapters for my camera?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eIt depends on what camera you are using. For cameras with a C-mount, no additional adapters are required. For cameras which mount with a 42mm thread, a 42mm (or T-thread) spacer ring to place the camera sensor at the proper backfocus distance relative to the optics will be needed. (Note: With the included 42mm camera adapter, the backfocus distance required is 25mm. So, subtract the backfocus distance specification for your camera from 25mm, and that is the length of the M42 spacer ring you will need. If the camera has a backfocus distance of more than 25mm, it cannot be used with the RASA 8.) For Sony and Canon mirrorless cameras, Celestron offers optional camera adapters. For other cameras, a custom camera adapter will be needed.\u003cstrong\u003eQ: What is the difference between the image circle and the useable field?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eThe image circle is the diameter at the focal plane (i.e. where the camera sensor is positioned) which the astrograph’s performance was optimized for. The useable field is the diameter at the focal plane where the performance of the astrograph is excellent. Most astrographs only mention the useable field in their specifications.\u003cstrong\u003eQ: What if my camera’s sensor is larger than the useable field?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eThe RASA 8 has a useable field of 32mm. A sensor with a diagonal size larger than that, such as a full-frame mirrorless camera, can be used, but there will be some drop off in optical performance and field illumination in the corners of the image. This may require cropping during image processing.\u003cstrong\u003eQ: Can filters be used with the RASA 8?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eThe RASA 8 has a removeable optical window which can be replaced with a filter. Currently, Celestron offers a Light Pollution Reduction Filter for the RASA 8. Filter “sliders” offered by some manufacturers may also work with some cameras. A filter wheel cannot be used, since the filter wheel would have to mount in front of the optics and would block too much of the incoming light.\u003cstrong\u003eQ: Why does the RASA 8 have a removeable optical window?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eWith such a fast optical system, you cannot add a filter into the light path without adversely affecting the optical performance. With a removeable optical window, you can replace the window with a filter with no loss of performance.\u003cstrong\u003eQ: Why is the fast focal ratio (F\/2.0) of the RASA 8 such a big deal?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eBecause it allows much shorter exposures to be used to capture detail in fainter astronomical objects. This makes getting good images much easier and quicker. With a sensitive high-speed camera along with live image stacking software, you can see images in “real-time” on your computer screen.\u003cstrong\u003eQ: What mounts can be used with the RASA 8?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eAny mount which can accept a CGE (or Losmandy D) dovetail bar and can handle at least 20 lbs. The RASA 8 weighs 17 lbs, and you’ll also need to account for the weight of your camera and any other accessories.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will I need to collimate (i.e. align) the optics?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eThe optics are aligned at the factory, and should not normally need adjustment. However, there are screws which adjust the tilt of the lens assembly should collimation adjustment ever be needed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is focus shift, and how does the Ultra-Stable Focus System (USFS) help to minimize it?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eFocus shift is when the image in your camera moves a little bit when focusing. This can make critical focusing more challenging. The RASA 8 focuses by moving the primary mirror inward-and-outward. If the mirror moves at all laterally, then focus shift will result. The USFS works by using pre-loaded precision ball bearings on the focus tube which the primary mirror rides on. This constrains any lateral motion of the primary mirror and minimizes focus shift. This also helps prevent any unwanted lateral motion of the primary mirror (also known as “mirror flop”) as the astrograph is pointed to different positions in the night sky.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the extended spectral range (400-800 nm) and what is the benefit?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eMost telescopes are designed to perform well over the visual spectrum (i.e 400-700nm). The RASA 8 optics were designed to perform over a wider spectral range, from 400-800nm. This means that light from 700nm-800nm will be well focused in the RASA 8, allowing more of the light emitted from the astronomical object to be sharply focused in the image. For cameras which have spectral response in the 700-800nm range, you’ll get brighter and sharper images and won’t necessarily need to use an IR-cut filter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What else might be needed with the RASA 8?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eA finderscope can be useful for visually finding objects or for initial alignment of your computerized mount with the night sky. The RASA 8 has mounting holes for a finderscope. If doing longer exposures, you may want to consider using a guide scope and autoguider in order to provide the best tracking performance with your mount. For convenient mounting of a guide scope, Celestron offers a CGE dovetail accessory mounting bar which connects to the top of the RASA 8 and allows easy installation of guide scope rings. Perhaps the most useful accessory is a focus motor, this permits focusing from the computer which is controlling the camera and\/or mount. A focus motor which is compatible with the RASA 8 will soon be introduced by Celestron.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the purpose of the integrated air-cooling system?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eThe RASA 8 will perform the best when its optics have reached thermal equilibrium with the outside air. The cooling system uses a fan and vents to pull air through the astrograph and around the primary mirror in order to help the RASA 8 reach thermal equilibrium more quickly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between RASA 8 and an 8” SCT or EdgeHD using the Starizona Hyperstar accessory?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eThe RASA 8 provides better optical performance and better field illumination than an 8\" SCT or Edge HD with a Hyperstar accessory. The Hyperstar accessory provides great flexibility for an SCT or EdgeHD optical system, as it allows the telescope to be used at two different focal lengths. When imaging at F\/2.0 however, it cannot provide the performance of the RASA 8.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What about dew?\u003c\/strong\u003e\u003cbr\u003e\u003cb\u003eA: \u003c\/b\u003eJust like any telescope design which uses a lens at the front of the telescope, the RASA 8 Schmidt corrector lens can be susceptible to dew under certain environmental conditions.

This fast, wide-field f\/2.2 system allows for shorter exposure times compared to traditional f\/10 astroimaging, without sacrificing resolution. Because shorter sub-exposure times are possible, your equatorial mount won’t need to accurately track over extended periods. The short focal length also lessens equatorial tracking demands. In many cases, autoguiding will not be required.\u003c\/p\u003e\n\u003cp\u003eRASA 11 V2 builds on the legacy of Celestron’s Schmidt Cameras, which allowed astrophotographers to produce images with much shorter exposure times on film in the 1970s.\u003c\/p\u003e\n\u003cp\u003eToday, with CCD sensor sizes as large as film or larger, the RASA 11 V2 offers a 43.3mm optimized image circle to capture pinpoint stars on the largest imaging chips.

The optical quality and spot size across the entire image circle are unprecedented for an astrograph in this price range—or even that of a much more expensive instrument.

At the heart of this system is a precision linear ball bearing. The bearing serves to minimize focus shift (unwanted lateral motion of the primary mirror during focusing which causes shifting of the image) and mirror flop (movement of the primary mirror when the telescope is pointing to different positions in the sky). The USFS is also compatible with the optional Celestron Focus Motor (#94155-A). The integrated 12V DC MagLev fan reduces cooldown time and provides optimal airflow through the dust filtered optical tube.\u003c\/p\u003e\n\u003cp\u003eEngineered as a complete astroimaging system, every component of the RASA 11 V2 is optimized for peak performance with DSLR and astronomical CCD cameras. Down to the thickness of the glass used in the included fully-multicoated optical window or optional imaging filter, every component of the system has been taken into careful consideration to work together seamlessly.

passionate about. From design to manufacture, our goal with the Corrected Dall-Kirkham (CDK) 12.5″ telescope was centered around performance and ease of use. The PlaneWave CDK 12.5 Fused Silica is an incredible breakthrough in telescope technology and produces no off-axis coma and no off-axis astigmatism. Additionally, the PlaneWave CDK 12.5 Fused Silica provides a perfectly flat field so your astrophotographs will have stunning clarity from corner to corner of the image without field curvature degrading the photos. Offering the simplicity of single-mirror collimation, the stray light control of advanced baffles, structural performance created through finite element analysis (FEA), and decades of telescope design experience, the CDK12.5 is an exceptional diffraction-limited telescope. CDK12.5 users can experience pinpoint stars edge-to-edge and a 70 x 70 arcminute field of view when using large camera sensors. When equipment fades into the background and simply performs, the astrophotography experience becomes even more fun and rewarding!\u003c\/p\u003e\n\u003cp\u003eThe PlaneWave CDK 12.5 Fused Silica is a 12.5 inch (0.32 m) f\/8 Corrected Dall-Kirkham Astrograph telescope.

The goal of the design is to make an affordable astrographic telescope with a large enough imaging plane to take advantage of the large format CCD cameras of today. Most telescope images degrade as you move off-axis from either coma, off-axis astigmatism, or field curvature. The CDK design suffers from none of these problems. The CDK is coma free, has no off-axis astigmatism, and has a flat field. The design is a simple and elegant solution to the problems posed above. The CDK consists of three components: an ellipsoidal primary mirror, a spherical secondary mirror and a lens group. All these components are optimized to work in concert in order to create superb pinpoint stars across the entire 52mm image plane.\u003c\/p\u003e\n\u003cp\u003eOptical Performance\u003cimg height=\"517\" width=\"410\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0609\/6673\/1845\/files\/Planewave-Spot-Diagram.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003eShown are two simulations showing the CDK’s stunning performance. The first is a diffraction simulation and the second is a spot diagram. In both simulations the small squares are 9×9 microns, about the size of a CCD pixel. In the diffraction simulation the star images on axis and off-axis are nearly identical. In the spot diagram 21mm off-axis the spot size is an incredible 6 microns RMS diameter. This means stars across a 52 mm image circle are going to be pinpoints as small as the atmospheric seeing will allow.\u003c\/p\u003e\n\u003cp\u003eBoth of the simulations take into consideration a flat field, which is a more accurate representation of how the optics would perform on a flat CCD camera chip. For visual use some amount of field curvature would be allowed since the eye is able to compensate for a curved field. The diffraction simulation was calculated at 585nm. The spot diagram was calculated at 720, 585, and 430nm. Many companies show spot diagrams in only one wavelength, but you cannot see the chromatic performance with only one wavelength.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eComparison: CDK vs. Ritchey Chrétien\u003c\/p\u003e\n\u003cp\u003e\u003cimg height=\"517\" width=\"410\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0609\/6673\/1845\/files\/PlaneWave-CDK-VS-RC.jpg\"\u003e\u003c\/p\u003e\n\u003cp\u003eThe simulations shown compares the optical performance of the CDK design to the Ritchey Chrétien (RC) design. The Ritchey design was popularized as an astroimaging telescope due to its use in many professional\u003c\/p\u003e\n\u003cp\u003eobservatories. Although very difficult and expensive to manufacture and align, the Ritchey is successful in eliminating many of the problems that plague many other designs, namely off-axis coma. However the Ritchey does nothing to eliminate the damaging effects of off-axis astigmatism and field curvature.\u003c\/p\u003e\n\u003cp\u003eThe CDK design tackles the off-axis coma problem by integrating a pair of correcting lenses into a two mirror design. The beauty is that this design also corrects for astigmatism and field curvature. Because the lenses are relatively close to the focal plane (unlike the Schmidt corrector plate found in various Schmidt Cassegrain designs), and because these lenses work together as a doublet, there is no chromatic aberration. The CDK offers a wide aberration-free, flat field of view that allows the user to take full advantage of the very large imaging chip cameras in the market place today.\u003c\/p\u003e\n\u003cp\u003eHaving an aberration free telescope design means nothing if the optics cannot be aligned properly. Many Ritchey owners never get to take full advantage of their instrument’s performance because the Ritchey is very difficult to collimate. Aligning the hyperbolic secondary mirror’s optical axis to the optical axis of the primary mirror is critical in the Ritchey design, and the tolerances are unforgiving. The secondary mirror of the CDK design is spherical. It has no optical axis and so the centering tolerance of the CDK secondary mirror is comparatively huge. With the help of some very simple tools, the CDK user will be able to set the secondary spacing, collimate the optics and begin enjoying the full performance potential the instrument has to offer within a few minutes.\u003c\/p\u003e\n\u003cp\u003eThe drastic difference in performance between the CDK and the RC is apparent. The biggest component that degrades the off-axis performance of the RC is the defocus due to field curvature. In many diagrams shown by RC manufacturers, the diagrams look better than this because they are showing a curved field. This is fine for visual use because the eye can compensate for some amount of curvature of field. But CCD arrays are flat and so in order to evaluate the performance a spot diagrams and\/or diffraction simulations requires a flat field as shown.\u003c\/p\u003e\n\u003ch5\u003ePlaneWave CDK 12.5 Specifications\u003c\/h5\u003e\n\u003ch6\u003eOPTICAL SYSTEM\u003c\/h6\u003e\n\u003ctable cellpadding=\"1\" width=\"824\" border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eAperture\u003c\/td\u003e\n\u003ctd\u003e318mm (12.5 inch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eFocal Length\u003c\/td\u003e\n\u003ctd\u003e2541 mm (100.04 inch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eFocal ratio\u003c\/td\u003e\n\u003ctd\u003ef\/8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eCentral Obstruction\u003c\/td\u003e\n\u003ctd\u003e42% of the Primary Mirror Diameter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eBack Focus from Mounting Surface\u003c\/td\u003e\n\u003ctd\u003e265mm (10.445 inch )\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eBack Focus from Racked in Focuser\u003c\/td\u003e\n\u003ctd\u003e183mm (7.2 inch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eOTA Length\u003c\/td\u003e\n\u003ctd\u003e787mm (31 inch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eOptical Tube\u003c\/td\u003e\n\u003ctd\u003eCarbon Fiber\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e\u003ca href=\"\/wp-content\/uploads\/2021\/08\/125101DIM-A.pdf\"\u003eOverall Dimensions (PDF)\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eWeight (includes manual-focuser and dovetail)\u003c\/td\u003e\n\u003ctd\u003e20.9 kg (46 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eWeight (includes electronic-focuser and dovetail)\u003c\/td\u003e\n\u003ctd\u003e22.0 kg (48.5 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch6\u003eSECONDARY MIRROR\u003c\/h6\u003e\n\u003ctable cellpadding=\"1\" border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eDiameter\u003c\/td\u003e\n\u003ctd\u003e118 mm (4.65 inch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePrecision Annealed Fused Silica\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eShape\u003c\/td\u003e\n\u003ctd\u003eSpherical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"40%\"\u003eCoating\u003c\/td\u003e\n\u003ctd\u003eEnhanced Aluminium -

From design to manufacture, our goal with the DeltaRho 350 was centered around creating a game-changing wide-field telescope. The DeltaRho 350 is a Cassegrain optical design which means the imaging train is secured at the back of the telescope and does not block the light path compared to prime focus designs, which severely limit users’ ability to operate with filterwheels or large cameras.\u003c\/p\u003e\n\u003cp\u003eThe DeltaRho 350 is an incredible breakthrough in telescope technology and ease of use. Operating at f\/3 and 1050 mm focal length, the DeltaRho is a wide-field telescope that is sure to revolutionize your astrophotography!\u003c\/p\u003e\n\u003cp\u003eAdditionally, the DeltaRho 350 provides a perfectly flat field so your astrophotographs will have stunning clarity from corner to corner of the image without field curvature degrading the photos. Offering the simplicity of single-mirror collimation, the stray light control of advanced baffles, structural performance created through finite element analysis (FEA), and decades of telescope design experience, the DeltaRho 350 is an exceptional telescope. DeltaRho 350 users can experience pinpoint stars edge-to-edge and a 170 x 170 arcminute field of view when using large 16803\/4040 size camera sensors. This field of view is nearly 3 times as large as our CDK14! When equipment fades into the background and simply performs, the astrophotography experience becomes even more fun and rewarding!\u003c\/p\u003e\n\u003ch3\u003eOptical System\u003c\/h3\u003e\n\u003ctable border=\"0\" width=\"551\" cellspacing=\"0\" cellpadding=\"0\"\u003e\n\u003ccolgroup\u003e \u003ccol width=\"232\"\u003e \u003ccol width=\"319\"\u003e \u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"xl65\" width=\"232\" height=\"21\"\u003eOptical Design\u003c\/td\u003e\n\u003ctd class=\"xl65\" width=\"319\"\u003eCorrected Dall-Kirkham (CDK)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"xl65\" height=\"21\"\u003eAperture\u003c\/td\u003e\n\u003ctd class=\"xl65\"\u003e350 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"xl65\" height=\"21\"\u003eFocal Length\u003c\/td\u003e\n\u003ctd class=\"xl65\"\u003e1050 mm (41.34 in.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"xl65\" height=\"21\"\u003eFocal ratio\u003c\/td\u003e\n\u003ctd class=\"xl66\"\u003ef\u003cspan class=\"font5\"\u003e\/3\u003c\/span\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eSecondary Mirror\u003c\/h3\u003e\n\u003ctable border=\"0\" width=\"551\" cellspacing=\"0\" cellpadding=\"0\"\u003e\n\u003ccolgroup\u003e \u003ccol width=\"232\"\u003e \u003ccol width=\"319\"\u003e \u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"xl65\" width=\"232\" height=\"21\"\u003eDiameter\u003c\/td\u003e\n\u003ctd class=\"xl65\" width=\"319\"\u003e7.48 in.

From design to manufacture, our goal with the Corrected Dall-Kirkham (CDK) 20″ telescope was centered around performance and ease of use. The Planewave CDK20 f\/7.7 OTA is an incredible breakthrough in telescope technology and produces no off-axis coma and no off-axis astigmatism. Additionally, the CDK20 provides a perfectly flat field so your astrophotographs will have stunning clarity from corner to corner of the image without field curvature degrading the photos. Offering the simplicity of single-mirror collimation, the stray light control of advanced baffles, structural performance created through finite element analysis (FEA), and decades of telescope design experience, the CDK20 is an exceptional diffraction-limited telescope. CDK20 users can experience pinpoint stars edge-to-edge and a 45 x 45 arcminute field of view when using large 16803 size camera sensors.

From design to manufacture, our goal with the DeltaRho 500 was centered around creating a revolutionary wide-field telescope. The DeltaRho 500 is a Cassegrain Optical Design with the imaging train at the back of the telescope to prevent obstruction of the instrument. This offers a real advantage against prime focus designs, which can severely limit users’ ability to operate with filter wheels or large cameras. Witness the incredible breakthrough in telescope technology as the DeltaRho 500 operates at f\/3 and 1537 mm focal length, which is sure to revolutionize your astrophotography.\u003c\/p\u003e\n\u003cp\u003eLast, but not least, the DeltaRho 500 provides a flat field, which ensures stunning clarity from corner-to-corner images without field curvature degradation. The DeltaRho 500 offers the simplicity of single-mirror collimation, stray light control of advanced 3D printed baffles, and structural performance created through finite element analysis (FEA). DeltaRho 500 users can experience pinpoint stars edge-to-edge and a 2-degree field of view when using large 16803\/4040 (52mm) size camera sensors. This field of view is over twice as large as our CDK 20! This kind of equipment allows users to experience a whole new level of wide-field imaging that can bring them closer than ever to deep space.
