Celestron Rowe-Ackermann Schmidt Astrograph (OTA Only)

You can have your very own backyard observatory. If you love the night sky and stargazing is one of your hobbies then the Celestron Rowe-Ackermann Schmidt Astrograph (OTA Only) is going to be the telescope of your dreams. You don't have to be an expert in Astrophysics and Cosmology to enjoy this optical tube, you can be a novice in astronomy and still get the most out of your Rowe-Ackermann Schmidt Astrograph.

Extraordinary Astroimages

Capturing impressive deep-sky astroimages is easier than ever with Celestron’s new Rowe-Ackermann Schmidt Astrograph, the perfect companion to today’s top DSLR or astronomical CCD cameras. This fast, wide-field f/2.2 system offers two huge advantages over traditional f/10 astroimaging: better apparent tracking and shorter exposures. That means you’ll create better-looking astroimages in a fraction of the time, even without the use of an autoguider. 

The Rowe-Ackermann Schmidt Astrograph builds on the legacy of Celestron’s Schmidt Camera, which allowed astrophotographers to produce images on film in the 1970s. Today, with CCD sensor sizes as large as film—or larger—the Schmidt Astrograph offers a 43.3mm optimized image circle to capture pinpoint stars on the largest imaging chips. Combine this large image circle with a focal length of just 620 mm and you have an instrument suitable for wide-field imaging, creating huge mosaics of the night sky, surveying, and even comet hunting. 

Optical Performance

The Rowe-Ackermann Schmidt Astrograph features newly designed optics with 4-element rare-earth glass for images free of false color and aberrations like coma and field curvature. The optical quality and spot size across the entire image circle is unprecedented for an astrograph in this price range—or even that of a much more expensive instrument. The design also provides minimal vignetting.

Advanced Features
Advanced features like a custom engineered linear brass focuser bearing and FeatherTouch Micro Focus Knob allow you to make the fine adjustments you need to capture the perfect shot. Meanwhile, a 12V MagLev fan reduces cooldown time and provides optimal airflow through the dust filtered optical tube. 

Engineered as a complete astroimaging system, every component of the Rowe-Ackermann Schmidt Astrograph 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 an optional imaging filter, every component of the system has been taken into careful consideration to work together seamlessly.

Celestron CGX-L Computerized Mount

Celestron's newly designed CGX-L Computerized Equatorial mount is the
latest addition to our fully computerized equatorial mount series.
Capable of carrying Celestron's largest optical tubes with ease, CGX-L
is designed for backyard observatories and remote imagers looking for
exceptional load capacity to weight ratio, compact design, and
innovative features that fully support large telescopes, imaging kits,
and the latest in wireless tech accessories. Key design goals included
larger 144 mm diameter worm wheels which provide smoother operation and
can more accurately drive heavier loads, longer 270 mm dovetail saddle
to support larger optical tubes, remote operation friendly features such
as home and limit optical sensors, easier polar alignment adjustments,
and better cable management overall. In addition to that, we've made
mechanical and ergonomic improvements throughout to make the mount
sturdier, easier to use, and easier to transport. COMPACT. ERGONOMIC.

Celestron CGX-L Tripod

  • Redesigned tripod has a widened stance for added stability. The minimum tripod height has also been lowered per user feedback
  • Tripod legs can be collapsed with accessory tray installed for faster setup and transport

Celestron Counterweight for CGE Pro Telescopes (22lb) (x2)

Make sure that your observation of the night sky is clear and accurate with the 22 lb. Counterweight from Celestron! Designed for efficiency and convenience, the telescope accessory balances the overall mass of a telescope’s optical tube working in conjunction with Celestron CGE Pro or CGEM DX equatorial mounts.


The Counterweight is especially effective in off-setting the weight added to your telescope by such heavy items as lens shades and tele-extenders. This balancing process also enables you to increase the weight of visual-side accessories on your telescope, including cameras and refractors, while still maintaining exquisite balance.


Because the Counterweight restores overall balance, it makes use of your telescope simple and more efficient; the balancing process makes handling your equipment easier and improves tracking accuracy. The unit also features a hand-tightened knob which holds it in place on the mount’s counterweight bar.

Perfect balance isn’t required to properly operate your telescope. As a matter of fact, flawless balance is not always possible when using fixed-position weights. But with Celestron’s Counterweight, you can achieve a desired balance and seriously reduce both shaking and swinging even when locks are released.


The Celestron 22 lb. Counterweight for CGE Mount is designed to help balance extra-heavy accessory loads (such as a large photoguide refractor, accessory dovetail, mounting rings, and a camera) on a Celestron telescope mounted on the Celestron CGE Pro or CGEM DX equatorial mounts. It will also let you install and balance a heavy non-Celestron scope on a Celestron CGE Pro or CGEM DX mount (which come with only one 22 pound counterweight as standard equipment when a mount is bought alone).

Featuring all the elements you need to protect your equipment and enrich your astronomical observations, the Celestron 22 lb. Counterweight is the ideal addition to your stargazing set-up!

  • Restores overall balance
  • Makes handling your equipment easier
  • Improves tracking accuracy
  • Seriously reduces both shaking and swinging
  • Designed to help balance extra-heavy accessory loads
  • Celestron Counterweight for CGE Pro Telescopes (22lb)
