Celestron - Advanced VX 9.25" Schmidt-Cassegrain Telescope (SCT)
Celestron - C9.25-A XLT - 9.25" SCT Optical Tube Assembly for CGE/ CGX - 91027-XLT
The Celestron C9.25-A CGE OTA is identical in every way to the CG-5 except for the Mount Attaching Rail that it comes with. Like most Schmidt-Cassegrain telescopes, the Celestron 9.25" OTA has a focal ratio of f/10, making itself quite suitable for either visual or imaging use. The XLT StarBright Multi Coatings leave the C9.25 XLT versatile for looking at many different celestial objects without the annoying optical disturbances caused by chromatic aberration. The StarBright XLT coatings bring excellent light transmission from the corrector to the eyepiece ensuring as little light wasted as possible to produce the brightest images. Schmidt-Cassegrain designs use both corrective plates and primary mirrors (aspects of both refractors and reflectors), resulting in the rather slow f/10 focal ratio of this telescope. It also will accommodate many accessories that can change it, making it even more suitable for faster CCD imaging or viewing. This also assists in astrophotography because faster focal ratios are more efficient when taking exposures with larger pixel sizes since slower focal ratios tend to take too long and often result in undesirable results (such as possible pixel blooming). For visual astronomy, a 6x30 finderscope, 25mm eyepiece eyepiece, 1.25" star diagonal, and 1.25" visual back are all included with the Optical Tube Assembly (OTA). This OTA is the very same quality as the tube assemblies that come with Celestron telescope packages but without the mount. This Celestron 9.25" SCT telescope package is a great way to upgrade, without the need to buy the whole telescope system.

Celestron - Advanced VX Computerized GoTo EQ Mount - 91519
The Celestron Advanced VX mount provides you with many of the features found on Celestron’s most sophisticated German Equatorial Mounts, at an extremely affordable price! Astroimagers and Visual Astronomers will appreciate the increased portability of this GoTo equatorial mount due to its lighter weight, while still using the powerful alignment and slewing tools found in larger mounts like the CGE and CGEM. The Advanced VX is stout enough to handle an 11" SCT due to the very solid stainless steel Tripod with 2" diameter legs. The All-Star Polar Alignment feature makes polar alignment a breeze. The programmable Periodic Error Correction built into the mount also assists in steady imaging since it eliminates tracking errors in the mount's brass drive gears thus minimizing image shifting during longer exposures. Due to the intelligent design of the VX, the meridian can also be imaged without flipping the GoTo equatorial mount around - a major plus for astrophotography! The Celestron Advanced VX Mount can be used between 7-77 degrees latitude and utilizes the NexStar hand controller for slewing and locating objects.
