  • Celestron 5″ Schmidt-Cassegrain Optical Tube Assembly
  • Aluminium Optical Tube
  • Celestron’s premium StarBright XLT coatings
  • 1250 mm focal length (f/10)

Please note, main image shows the very similar 6" version. Only for demonstration purposes.


The C5 is a 5″ aperture Schmidt-Cassegrain optical system has a 1250mm focal length (f/10) and comes as standard with Celestron`s StarBright® XLT coatings, a 1.25″ eyepiece, star diagonal and 6×30 finderscope. The telescope also has a CG-5/Vixen-style dovetail for attaching it to popular mounts (e.g. Advanced VX). This C5 – Advanced VX (AVX) telescope package is the most portable of Celestron’s AVX range.

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.
