PlaneWave L350 Direct Drive Mount
The L-Series combines versatility, simplicity and affordability by combining all the technology of our Observatory class telescopes into a compact stand-alone mount. 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. Besides, it is the way the pros do it!
L-Series Mounts Features:
- Direct-drive motors on each axis for smooth, fast, and virtually silent movement of the telescope
- Slew speeds up to 50 degrees per second

Introducing the new Paramount MX Series 6 transportable observatory.
The Paramount MX Series 6 represents the latest in gear-driven GEM performance.
Its new features include a 25% instrument capacity increase, an option for absolute digital encoders, and multiple connectivity options.
The MX German equatorial mount has always been a popular Paramount model and the new Paramount MX Series 6 offers several important improvements.
On-axis Absolute Encoders vs. Motor-based Encoders.
Paramount's equipped with on-axis absolute encoders know where they are at all times. Paramount's with incremental encoders (or motor-based encoders) know only how far they have moved since they were initialized using a nightly process called homing.
The crucial additional difference is that the on-axis absolute encoders are fitted directly to the mount axes themselves, bypassing the worm drives. Paramount's with incremental encoders are fitted to the worms instead, which means that with incremental encoders alone, periodic errors in the worm drive show up in the tracking. These mounts must be calibrated and corrected using a process called periodic error correction (PEC), which measures and records the repeatable gear train errors and removes them. (TheSky features advanced, multi-harmonic PE detection and PEC calibration that minimizes periodic error in mounts with incremental encoders.)
For mounts with incremental encoders, homing re-zeros the encoders when precise sensors on each of the axes are reached. From then on, the incremental encoders are in effect delivering absolute readings.
However, 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.
High-resolution on-axis absolute encoder technology is significantly more expensive than incremental encoders.
Are on-axis absolute encoders right for me ?
The short answer is, “it depends.”
Gear-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.
These 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 uncorrected 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 Find Home process that usually takes a minute or less to complete.
So, at least with Paramounts, periodic error is effectively in the noise, and homing straightforward.
What about pointing and tracking?
Without 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).
Paramount’s exceptional software makes the above performance possible. TheSky Professional edition, in conjunction with TPoint™ and ProTrack™ the mount’s position is continually updated in both axes to correct system-wide pointing and tracking errors caused by tube flexure, atmospheric refraction, polar misalignment, harmonic errors from mis-centered encoders and/or worm gears, and more.
On-axis absolute encoders alone cannot correct these errors which exist with all telescopes. A properly applied telescope model is necessary to achieve superior pointing and tracking.
So are on-axis absolute encoders right for you? Perhaps if you want to enjoy the conveniences mentioned above. And for many, that’s enough. With that said, the optional on-axis 26-bit Renishaw absolute encoders with 0.02 arc second precision are the finest available and they operate in temperatures between +80°C and –40°C.

- Optional 26-bit Renishaw encoders eliminate periodic error and the need for homing; operates in temps as low as –40° C
- If you skip encoders now and later decide you want them, they can be retrofitted on the Paramount MX Series 6
- As there’s some confusion about what encoders can and cannot do, there’s an FAQ below that elaborates on that and whether they’re right for you
- Its encoder cables are located inside the mount to help prevent snags.
- All electronics and through-the-mount cables are housed inside the mount with ample room for additional cables

- Calibrated azimuth and elevation polar alignment adjustments speed polar alignment
Software Specifications
- Paramount’s unequaled pointing and tracking wouldn’t be possible without its TPoint™ and ProTrack™ software.
- By employing TPoint’s calibration and telescope modeling tools, you’ll enjoy all sky pointing accuracies at or below 30 arcseconds RMS.
- Operating in conjunction with TPoint ™, ProTrack™ continuously updates the mount’s position across both axes to correct system-wide tracking errors including tube flexures, atmospheric refraction, polar misalignment, harmonic errors from mis-centered encoders, and more.
- On-axis absolute encoders alone cannot correct these errors which exist with all telescopes. A properly applied telescope model is necessary to achieve superior tracking.
- Without encoders, Paramounts can deliver uncommonly long unguided exposures (one customer reported 20 minutes).
- For more information about what encoders can and cannot do, please see the FAQ below.
- All the included software is integrated into a single, easy-to-use, application consisting of TheSky™ Professional, TPoint™, Cameras+, Domes, Multi-OS+, and Weather modules.
- You can control all your astrophotography-related cameras and devices with this one app.
- It runs on macOS™, Windows™, Ubuntu™, and Linux (x86_64 and ARM64 architectures).
- Regardless of the operating system you run it on, it appears and operates identically. You can even switch between operating systems and its license allows up to six computers. Why paint yourself or your institution into a corner?
- Absent ProTrack™ which is unique to Paramounts, the included software is sold separately as TheSky™ Universal Bundle and represents a US$1,095 value.

Introducing the new Paramount ME Series 6 observatory workhorse.
The Paramount ME Series 6 represents the latest in gear-driven GEM performance.
Its new features include a state-of-the-art MKS 6000 telescope control system that lets you connect via USB C, Ethernet, and Wi-Fi. Its two-port USB 2.0 hub is conveniently located on the instrument panel
The Paramount ME Series 6 remains an observatory favorite among professional and advanced-amateur astronomers.
On-axis Absolute Encoders vs. Motor-based Encoders.
Paramount's equipped with on-axis absolute encoders know where they are at all times. Paramount's with incremental encoders (or motor-based encoders) know only how far they have moved since they were initialized using a nightly process called homing.
The crucial additional difference is that the on-axis absolute encoders are fitted directly to the mount axes themselves, bypassing the worm drives. Paramount's with incremental encoders are fitted to the worms instead, which means that with incremental encoders alone, periodic errors in the worm drive show up in the tracking. These mounts must be calibrated and corrected using a process called periodic error correction (PEC), which measures and records the repeatable gear train errors and removes them. (TheSky features advanced, multi-harmonic PE detection and PEC calibration that minimizes periodic error in mounts with incremental encoders.)
For mounts with incremental encoders, homing re-zeros the encoders when precise sensors on each of the axes are reached. From then on, the incremental encoders are in effect delivering absolute readings.
However, 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.
High-resolution on-axis absolute encoder technology is significantly more expensive than incremental encoders.
Are on-axis absolute encoders right for me ?
The short answer is, “it depends.”
Gear-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.
These 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 uncorrected 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 Find Home process that usually takes a minute or less to complete.
So, at least with Paramounts, periodic error is effectively in the noise, and homing straightforward.
What about pointing and tracking?
Without 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).
Paramount’s exceptional software makes the above performance possible. TheSky Professional edition, in conjunction with TPoint™ and ProTrack™ the mount’s position is continually updated in both axes to correct system-wide pointing and tracking errors caused by tube flexure, atmospheric refraction, polar misalignment, harmonic errors from mis-centered encoders and/or worm gears, and more.
On-axis absolute encoders alone cannot correct these errors which exist with all telescopes. A properly applied telescope model is necessary to achieve superior pointing and tracking.
So are on-axis absolute encoders right for you? Perhaps if you want to enjoy the conveniences mentioned above. And for many, that’s enough. With that said, the optional on-axis 26-bit Renishaw absolute encoders with 0.02 arc second precision are the finest available and they operate in temperatures between +80°C and –40°C.
Hardware Specifications
- 109 kg instrument capacity; 218 kg maximum payload capacity (instruments + counterweights)
- All sky pointing accuracies at or below 30 arcseconds RMS
- Unibody mount design weighs 38 kg without counterweights or counterweight shaft
- Maximum seven (7) arcseconds peak-to-peak periodic error before correction
- After a one-time training, periodic error is 1 arcsecond, peak-to-peak or less
- Optional 26-bit Renishaw encoders eliminate periodic error and the need for homing; operates in temps as low as –40° C
- If you skip encoders now and later decide you want them, they can be retrofitted on the Paramounts ME Series 6
- As there’s some confusion about what encoders can and cannot do, there’s an FAQ below that elaborates on that and whether they’re right for you
- Its encoder cables are located inside the mount to help prevent snags.
- All electronics and through-the-mount cables are housed inside the mount with ample room for additional cables

- Belt-driven gears with spring loaded worm gears produce virtually zero backlash
- Durable and fade-resistant red powder coating and black anodized finish; components are aluminum
- Clutch-free design helps maintain its TPoint™ assisted pointing accuracy
- AutoHome™ homing capability ensures the mount always knows its orientation (after performing an initializing process called “homing” that typically takes less than a minute)
- Calibrated azimuth and elevation polar alignment adjustments speed polar alignment
Software Specifications
- Paramount’s unequaled pointing and tracking wouldn’t be possible without its TPoint™ and ProTrack™ software.
- By employing TPoint’s calibration and telescope modeling tools, you’ll enjoy all sky pointing accuracies at or below 30 arcseconds RMS. Nothing outperforms that
- Operating in conjunction with TPoint ™, ProTrack™ continuously updates the mount’s position across both axes to correct system-wide tracking errors including tube flexures, atmospheric refraction, polar misalignment, harmonic errors from mis-centered encoders, and more.
- On-axis absolute encoders alone cannot correct these errors which exist with all telescopes. A properly applied telescope model is necessary to achieve superior tracking.
- Without encoders, the Paramount ME Series 6 can deliver uncommonly long unguided exposures (one customer reported 20 minutes).
- For more information about what encoders can and cannot do, please see the FAQ below.
- All the included software is integrated into a single, easy-to-use, application consisting of TheSky™ Professional, TPoint™, Cameras+, Domes, Multi-OS+, and Weather modules.
- You can control all your astrophotography-related cameras and devices with this one app.
- It runs on macOS™, Windows™, Ubuntu™, and Linux (x86_64 and ARM64 architectures).
- Regardless of the operating system you run it on, it appears and operates identically. You can even switch between operating systems and its license allows up to six computers. Why paint yourself or your institution into a corner?
- Absent ProTrack™ which is unique to Paramount, the included software is sold separately as TheSky™ Universal Bundle and represents a US$1,095 value.

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.
The 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.
RASA 36 c sample back-focus distance (77.5 mm) accommodates a wide variety of imaging sensors. A custom camera adapter can be added for a field of view up to 4.4 degrees.
Important freight requirement RASA 36 is a professional-caliber, high-precision instrument. It is manufactured and aligned to an exacting standard to provide exceptional optical performance. The telescope has been packaged to ensure it retains alignment and resulting performance during transport. However, due to the weight, size, and known stresses of shipping via parcel service, Celestron has determined that the ideal transport is a palletized delivery via LTL truck freight. For all Australian deliveries, Celestron will ship via this method. Please contact us for further freight costs

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. When equipment fades into the background and simply performs, the astrophotography experience becomes even more fun and rewarding!
Carbon Fiber Truss Design
Minimizes thermal expansion which causes focus shift as temperature changes during an imaging session. Carbon fiber also reaches ambient temperatures quickly and is extremely lightweight and rigid to help ensure excellent imaging data is produced.
3D Printed Baffles
PlaneWave uses digital 3D printing technology to produce lightweight baffle tubes. 3D printers add successive layers of material to construct a baffle system with precision positioned internal stray light baffles to minimize vignetting and maximize image contrast. Quality baffling makes an incredible difference in overall image quality, so we ensured an optimal design was created for our telescopes.
Dovetail Expansion Joint
Allows for the difference in thermal expansion between carbon fiber and aluminum. The expansion joint allows the aluminum dovetail to expand and contract without stressing the carbon fiber lower truss. This results in images that are not distorted due to expansion, or contraction of the optical tube materials.
Delta-T Ready
For added dew prevention, the Planewave CDK20 f/7.7 OTA is internally wired with polyimide film heater pads and temperature sensor, which is ready to be controlled with the Delta-T via PlaneWave Interface 3 software.
Cooling Fans
Three fans on the backplate of the optical tube pull air through the telescope and by the primary mirror. Three fans on the side of the optical tube also blow air across the primary to ensure a boundary layer of air does not distort images. These fans help the telescope reach thermal equilibrium quickly, further reducing any distortion in images due to temperature variations. The fans are controlled by a switch on the optical tube, or can be controlled by via PWI3 software if a PlaneWave Electronic Focus Accessory (EFA Kit) is purchased.

Technology
The CDK Optical Design
The CDK
Optical Performance
Shown 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.
Both 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.
Comparison: CDK vs. Ritchey Chrétien
The 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
observatories. 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.
The 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.
Having 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.
The 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.

PlaneWave CDK 14" Fused Silica
The CDK (Corrected Dall-Kirkham) Optical Design is an innovative solution for unsurpassed astroimaging quality at an affordable price. The CDK telescope design provides excellent imaging with large format CCD cameras while remaining superb for visual use. The CDK design far exceeds the off-axis performance of most commercial telescope designs including the Ritchey-Chrétien design.
FUSED SILICA
Fused Silica is a synthetic amorphous silica glass of the highest purity and one of the most transparent glasses made.
The optical and thermal properties of fused silica are superior to other types of glass due to its purity. Its transmission and homogeneity exceed those of crystalline quartz without the problems of temperature instability inherent in the crystalline form.
Fused Silica has a coefficient of thermal six times lower than Borosilicate glass, which means that as fused silica cools down, it preserves its shape to a high degree of accuracy. This translates into consistent optical performance and unchanging focus over temperature changes.
With high melting temperature (~1,600 degrees Celsius), a very low coefficient of thermal expansion and resistance to thermal shock, fused silica is the material of choice for professional observatories as well as various scientific applications.
This no-compromise design is unique in making the optical alignment forgiving and collimation very easy. This guarantees the user the best possible performance from the telescope. The end result at the image plane of the CDK design is no off-axis coma, no off-axis astigmatism, perfectly flat field (no off-axis defocus). The CDK design will give you pinpoint stars from the center to the corner of the field of view.
