It offers unprecedented value in aperture, speed, field of view, and optical performance. The RASA design has a convenient external prime-focus image capture location with a flat focal plane, providing small spot sizes to the edge of a wide field. The result is images free of optical defects like field curvature, off-axis coma, and astigmatism.\u003c\/p\u003e\n\u003cp\u003eThe 36 cm aperture version is the largest RASA Celestron manufactures; it is the biggest and fastest (f\/2.2) optical instrument of its kind available off-the-shelf. Unlike most telescopes, which only focus visible light (400-700 nm), the RASA 36 cm focuses an extended spectral range (400-900 nm), allowing a brighter signal to be detected by a camera sensor. The RASA 36 cm also features a redesigned focus system, which ensures easy and stable focusing.\u003c\/p\u003e\n\u003cp\u003eRASA 36 c sample back-focus distance (77.5 mm) accommodates a wide variety of imaging sensors.

In its Alt\/Az configuration it is considerably more compact than its equatorial counterpart, allowing a larger telescope to fit in a smaller enclosure. Unlike German Equatorial mounts, there are no meridian flips to deal with, and no large protruding counterweights to create a dangerous hazard in a public observatory. Alt\/Az is more intuitive to use and no polar alignment is needed.

The mass it takes to make a rigid alt\/az mount is substantially less, leading to cost savings. Unlike German Equatorial mounts, there are no meridian flips to deal with, and no large protruding counterweights to create a dangerous hazard in a public observatory.

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 -

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!

From then on, the incremental encoders are in effect delivering absolute readings.\u003c\/p\u003e\n\u003cp\u003eHowever, the crucial additional difference remains, namely that the incremental encoder system is behind the worm drive, and periodic error correction is still required to get the best out of the RA tracking.\u003c\/p\u003e\n\u003cp\u003eHigh-resolution on-axis absolute encoder technology is significantly more expensive than incremental encoders.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eAre on-axis absolute encoders right for me ?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe short answer is, “it depends.”\u003c\/p\u003e\n\u003cp\u003eGear-driven Paramounts equipped with on-axis absolute encoders do not have periodic error, require no mechanical initialization (or homing), and the number of TPoint pointing samples needed for precision calibration is reduced.\u003c\/p\u003e\n\u003cp\u003eThese advantages expedite nightly setup, negate one-time periodic error training, and shorten the calibration process require to achieve spectacular pointing and tracking performance. However, the Paramount worm gear's \u003cem\u003euncorrected\u003c\/em\u003e periodic error is low (below 7 arc seconds peak to peak), and, after a one-time PE training, periodic error correction (PEC) generally make it negligible. The Paramount without on-axis absolute encoders requires a nightly \u003cem\u003eFind Home\u003c\/em\u003e process that usually takes a minute or less to complete.\u003c\/p\u003e\n\u003cp\u003eSo, at least with Paramounts, periodic error is effectively in the noise, and homing straightforward.\u003c\/p\u003e\n\u003cp\u003eWhat about pointing and tracking?\u003c\/p\u003e\n\u003cp\u003eWithout on-axis absolute encoders, Paramounts routinely produce 5-to-10-minute unguided exposures; many have reported 20 minutes. Also without on-axis absolute encoders, Paramount’s produce all-sky pointing accuracies at or below 30 arcseconds RMS (usually less than 15 arcseconds on fixed mirror telescopes).\u003c\/p\u003e\n\u003cp\u003eParamount’s exceptional software makes the above performance possible.

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.
