- 6 (150mm) f/5 optical design gives excellent wide field views
- Parabolic primary mirror minimizes spherical aberration to produce a better image
- The most compact and portable of Celestron's German equatorial mounts offers the same rigidity as our larger mounts with minimal flexure and an improved industrial design
- Holds a maximum instrument capacity of 30 lb
- Every feature an astroimager wants: PEC, an autoguider port, the ability to image across the meridian, and more
- Dual saddle plate is compatible with narrow CG-5 dovetails and wider CGE dovetail. Also compatible with Vixen format dovetails longer than 100mm, but not compatible with Losmandy D format plates.
- Latitude range allows the mount to perform between 7° and 77° latitude
- Accessories include a 20mm eyepiece and 6x30 finderscope
I have an optical tube equipped with a Losmandy D dovetail mounting plate. Will this work with the improved Advanced VX (AVX) mount?
No, the Losmandy D dovetail plate will not fit the improved AVX mount. The improvement to the AVX mount allows it to be used with CGE format dovetail plates, but not Losmandy D format plates. The CGE and Losmandy D formats are similar, but not exactly the same. Losmandy plates are a millimeter or so wider, but CGE plates allow more surface area contact with the dovetail clamp.
What prevents the Losmandy D plates from working with the improved AVX?
The improved AVX can accept a dovetail with a maximum width of 74.5mm. The Losmandy D plate is a bit wider than that. Also, the improved AVX requires the height of the dovetail undercut to be at least 10.2mm, and the Losmandy D has a dovetail undercut which shorter than that.
So, how do I mount my optical tube with a Losmandy D dovetail plate onto the improved AVX?
You'll need to replace the Losmandy D dovetail plate with a compatible dovetail plate, such as the Celestron #94214 CGE Universal Mounting Plate.
I have a Losmandy D format dovetail plate, but it is not manufactured by Losmandy. Will it work with the improved AVX?
No, if the dovetail plate uses the Losmandy D format, then it is not compatible with the improved AVX, regardless of the manufacturer of the plate.
I have an optical tube equipped with a Vixen dovetail mounting plate. Will this work with the improved AVX mount?
Yes, the improved AVX, like the original AVX, is compatible with Vixen format dovetail plates. However, the plate must have a dovetail length of 100mm or greater.
Why does my Vixen dovetail, or CG-5 dovetail, need to have a dovetail length of at least 100mm?
The knobs on the AVX that hold the dovetail plate in place are spaced 90mm apart. If the dovetail length is less than 100mm, then both knobs cannot come into contact the dovetail simultaneously. See the below engineering drawing.
My optical tube has a Vixen or CG-5 dovetail plate with a dovetail length of less than 100mm. How do I mount it onto the AVX?
You'll need to replace the dovetail plate with a compatible dovetail plate, such as the Celestron #94213 Universal Mounting Plate, CG-5.
