Description

This 11" aperture optical tube assembly (OTA) is an ideal choice if you want a very large aperture telescope that won't break the bank. With its 11" aperture the telescope is still not too large or too heavy to handle meaning that it can be used on a wide range of popular mid-range mounts such as Celestron's Advanced VX. For astroimaging we would recommend the Celestron CGX or CGX-L mount. The C11 features Celestron's StarBright XLT coatings on the corrector plate for maximum light transmission. The telescope has a 2800mm focal length (f/10) making it a good overall performer on a range of celestial objects. The telescope comes with a star diagonal for more comfortable viewing of high altitude objects and a 40mm Plossl eyepiece which gives 70x magnification. A 9x50 finderscope to help locate objects completes the package. 

Celestron's Advanced VX (AVX) series mount is the smallest of its computerised GOTO equatorial mounts and is designed for use with up to medium sized telescopes with the mount able to carry just over 13kg of payload. The AVX has been designed and engineered from the ground up with astroimaging in mind and sets a new standard in mid-level telescope mounts. It provides many of the features that are found on Celestron’s more sophisticated German equatorial mounts, but at an extremely affordable price. It is designed to provide superior performance for small to mid-size telescopes while taking advantage of Celestron’s most advanced technologies: All-Star Polar Alignment, Celestron PWI telescope control software, SkyAlign, and permanently programmable periodic error correction (PPEC).

The mount includes ports for a hand control, an autoguider, and 2 AUX ports for optional accessories (e.g. StarSense). The NexStar+ hand control gives you instant access to all the functions the mount has to offer. With automatic slewing and menu descriptions, any level of astronomer can master this mount in just a few observing sessions. The AVX also has an impressive tripod with 2” diameter steel legs providing an extra-wide stance for improved stability.

The mount can now be used with Celestron's PWI (CPWI) software, co-developed with the PlaneWave Instruments, which is an all-in-one solution offering you many of the same features used on PlaneWave’s observatory-class telescopes. The software features a graphical planetarium interface and includes PointXP advanced mount modelling which allows you to add 100+ points to your alignment model for the mount for the most accurate pointing and tracking possible. this makes the AVX with the CPWI software and ideal solution for remote access observatory setups. The mount can also be controlled via the ASCOM telescope interface so it can be used with third party software applications. For more information on CPWI and to see the user interface, click here.

Please note: a new dual CG-5/CGE saddle version is being phased in across the AVX model range as new stocks arrive in the UK. The image below shows the dual saddle.
