The C9 1/4-AVX combines the quality optics of a Celestron 9 1/4" Schmidt-Cassegrain telescope with the computer-controlled parallactic Advanced-VX mount and thus provides an affordable introduction to astrophotography.
The 9 1/4" was specially designed for observations with 2" eyepieces and has an optimized aperture system to minimize vignetting at the edge of the image field during photography. Its primary mirror with longer focal length and the secondary mirror with lower magnification enable a flatter image and reduce optical aberrations.
You can easily balance the telescope with the adjustable counterweight. The optics deliver clear images thanks to the StarBright XLT coating and collect 33% more light than the 8" model. The optimized aperture system increases the contrast when observing planets and is advantageous for astrophotography. An optional polar finder scope and the software routine of the hand control box facilitate polar alignment.
Since spring 2019, it has been supplied with the dual dovetail clamp so that telescopes with both the small CG5 rail (EQ standard) and the large CGE rail (3" standard) fit on the AVX - without additional adapters! All you have to do is move the clamping screws. Larger telescopes in particular benefit from the wider rail, which offers more stability.
Dovetailplates from third-party suppliers
Vixen
The Advanced VX is still compatible with dovetail bars in Vixen format. However, the rail must be at least 100 mm long, as the clamping points of the new AVX are 90 mm apart. If a user wants to use the AVX with a telescope whose Vixen (or CG-5) dovetail bar is shorter than 100 mm, the bar must be replaced with a longer dovetail bar. Appropriate rails are available from us.
Losmandy
The new AVX mount is not compatible with Losmandy D format dovetail bars. The CGE and Losmandy D formats are similar, but not identical. Losmandy rails are about one millimeter wider, while CGE plates are deeper and have more surface contact with the dovetail clamp. To use an AVX with a telescope with a Losmandy D dovetail bar, the existing bar must be replaced with a compatible dovetail bar. Appropriate rails are available from us.
State-of-the-art technology for mobile use
Celestron Advanced VX mounts set the standard for medium-sized telescopes up to approx. 15 kg. The mount was developed from scratch, always with astrophotography in mind. It offers many of the features of the large Celestron mounts at a very attractive price - and the axis cross weighs only 7.7 kg!
Solid castings and heavy-duty mechanics
Based on the proven Advanced GT mount, the Advanced VX not only offers large, easy-to-grip adjustment screws and stronger motors that cope even better with unevenly distributed loads, but also a wider base for the tripod connection and an improved dual dovetail mount with two clamping screws. No premature tilting! Tracking is possible up to 20° beyond the meridian passage.
State-of-the-art software
The AVX mount is supplied with the cold-resistant, significantly more powerful NexStar+ hand controller. This provides you with modern computer control - with over 40,000 objects and German menu navigation. Thanks to the built-in clock, commissioning is even faster than before. The software automatically moves to the reference stars, you only have to center them in the eyepiece. Even the sun can be used as a reference object.
Alignment made easy
With the AVX, you no longer have to laboriously set the pole star using the polar finder: Align the mount roughly to the north, perform a 2-star alignment - and then call up the All-Star Polar Alignment. The software will now help you to align the mount precisely, even if you cannot see Polaris. You can look comfortably through the telescope and do not have to kneel under the polar finder (still available as an option).
Versatile and expandable
In addition to a USB port on the hand controller, the AVX also has an autoguider input and two AUX ports. Here you can connect additional, separately available expansion modules - for example the SkyQ Link module for control via WLAN with iPhone/iPad/Windows PC or the StarSense module, with which the mount automatically approaches and perfectly centers its reference stars.
Experienced photographers will appreciate how easily this mount can be transported to a dark observation site. If you are new to astronomy or astrophotography, the Advanced VX will help you get started and can serve you well for many years to come.
Avoid damage to the electronics - remember the right power supply unit!
To ensure that the device operates correctly, please only use high-quality power supply units that also meet the specifications for astrophotography, i.e. for outdoor use - cheap power supply units often only deliver the specified voltage and power at room temperature and can even damage the electronics in the worst case. Suitable high-quality power supply units can be found on the left under Optional accessories.
