DESCRIPTION

Celestron CGX-L Equatorial 1100 Rowe-Ackermann Schmidt Astrograph

The Rowe-Ackermann Schmidt Astrograph Design

The Rowe-Ackermann design pairs speed with performance. Based on the original Schmidt camera design, the RASA optical tube offers major advantages to astrophotographers by giving you a short focal length for relatively a large aperture. The result is a wide-field f/2.2 system offering the advantage of better apparent tracking. With only a 620mm focal length, exposure times are also greatly reduced when compared to traditional Schmidt Cassegrain telescopes. You'll be capturing better images in a fraction the time, without the need of an autoguider!

As CCD imaging has advanced, large sensors have become readily available in increasingly more affordable cameras. While the imaging hobby has grown in leaps and bounds there has been very little changed in optical designs to accommodate these large imaging sensors. That is until now. The Celestron RASA offers an exceptionally sharp 43.3mm image circle. This creates such a wide field, you'll be able to fill even the largest imaging chips with edge-to-edge pinpoint stars with minimal vignetting. The Rowe-Ackermann scopes are perfect for creating giant night sky mosaics, surveying and comet hunting. Designed with 4-element rare-earth glass, images are free of false color, coma, and field curvature. Optical quality this excellent has been unheard of in astrographs within this price range.

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. There are autoguider and USB ports for your convenience -four total auxiliary ports.  

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.

Includes M48 and T-Thread camera adapters.

 

 

Celestron CGX-L Computerized Mount


Heavy Duty on a whole new level...!
They spent years redesigning the CGEM to create the CGX, innovating on a brilliant level to create a mount that surpassed previous German Equatorial mounts in almost all fields possible. They produced an impressively efficient mount capable of performing to the highest degree of capacity... and in the time since then, they've only kept working on their designs! Now they are presenting the CGX-L, an up-scaled and improved variant on the CGX designed to be ideal for personal observatories and remote imaging sites. This design heavily improves the weight capacity of the original mount, and utilizes a wide variety of new and improved traits to all around exceed the CGX- a high benchmark to rise above!

The backlash for this amazing mount is absolutely minimal, showing this design for the top of the line quality item that it is. This is aided by the belt-driven worm gears, which have been spring loaded for optimal gear meshing, and then enlarged to a full 144mm in diameter, to more accurately drive the heavier loads this mount was meant to carry. The weight capacity is declared as 75lbs- and that's a humble declaration, to say the least. This piece of hardware is even tougher than its smaller cousin, the XG- which itself is one of the most solid things on the market, absolutely capable of blowing away anything similar priced in sheer quality. This places the CGX-L in the enviable position of having been designed by the CGX's creators specifically to exceed it.

One of the more impressive features of this mount is the internal cabling in the Go-To system. The way it's designed, almost all the cabling is internal. This means you don't need to worry about re-positioning your initial wiring setup once you've hooked the mount up, to begin with; because all the cabling is internal, none of it is in the way to get tangled up and cause issues for you while you observe using the (Impressively potent!) Go-To capabilities of this mount. Your power supply and accessories can simply plug into a stationary port on the mount's body, and then never be worried about for the rest of your night!

The motors are another place where the improvement of the CGX base design over other German Equatorial Mounts is self-evident. They are able to provide notably more torque when active, while the design of the mount ensures that everything is controlled to the tightest, smoothest degree. This innovative mount has a lower profile than most other GEM's as well, giving it a great boost to both stability and portability with its lower center of gravity and compact design. And then it goes a step further in the aim of that goal, as the EQ head's position is adjustable, allowing you to optimize it to match your tripod perfectly for an ideal center of gravity. This mount continues to impress with its next notable feature; a dual fit head that permits a Vixen or Losmandy style dovetail, massively increasing the range of scopes that can be mounted atop this beautiful device! The dovetail saddle has been expanded to 270mm, allowing it to support larger optical tubes and broader payloads.

As a quick summary- The CGX-L is simply more responsive, with enlarged spring-loaded worm gears and belt drives that minimize backlash. Internal cabling means power and accessory ports do not move with the mount, and there are also home and limit switches, as well as internal hard stops for both RA and Dec to prevent cable wrap and tripod strike. Ergonomics have also been massively improved overall, ranging from the carry handles to the adjustment knobs, making setup and takedown both infinitely easier. Another fascinating feature is that there is a clear window built into the motor covers, letting you keep an eye on the pulleys and belts.

And lest we forget- this is most definitely a Go-To mount. Coming with the splendid quality NexStar hand controller and a database of over 40,000 objects, this state of the art mount is definitely ready to take you on the greatest trip of the night sky possible! The Celestron CGX-L Equatorial Mount tracks 20-degrees past the meridian on either side to maximize the best imaging time. Technologies such as SkyPortal WiFi and StarSense AutoAlign are supported, and All-Star Polar Alignment technology is built-in, for faster and easier polar alignment. New telescope control software for automation and remote operation has been designed for the Celestron CGX in conjunction with Planewave Instruments. This software features multi-point GoTo modeling, focusing and plate solving. With this innovative software, no third party advanced PC control software is needed! An intuitive hand controller allows you to align and move the CGX-L with ease.

This already top notch mount comes atop a tripod perfect for use with it. The sturdy 2.75-inch thick steel legs come with graduated markings that make leveling quicker and easier all around, and an included spreader bar adds even greater stability to this heavy-duty tripod while also giving you a few more places to store your eyepieces between use!

The mount itself weighs in at a solid 52 pounds, and the heavy duty 70mm steel tripod it rests atop at 46 pounds.

This RASA CGX telescope package includes a 2 year Celestron warranty.
