Check the camera literature to determine the camera's thread size and select this option above so the camera will thread to the flattener. Also make sure the total camera backfocus is 55mm. If not, email us at firstname.lastname@example.org and we will help you get what you need.

The flattener is solidly made. I particularly like that it is not adjustable. Stellarvue has chosen to use extensions to reach the proper backfocus for the imaging train. I would recommend buying the SFA-M63F48-005 ring and filter adapter if you are not going to be using a filter wheel. I realized this and purchased it even before my scope arrived.
The lenses were super clean and it came well packed (over packed?). Attaching this to the scope is easy and adding filters will not cause changes like adjustable flatteners do.
I have been able to use this one night. The stars are perfectly round, even to the corners.
This is a must for astrophotography and I can say that the quality is in line with what I expect from Stellarvue.
Bought this to optimize my SVX102T-R for astrophotography with the ZWO ASI533MC Pro camera. Using this with manual focus on the 3" FT focuser I see no distortion across the complete field in my images. Very well made and absolute perfect fit.
I installed this Flattener on my SV 110 ED and Viola my oblong stars are Gone!!
Thanks to Vic for his great assistance
A flattener is needed on refractors to produce a perfectly flat field of stars. This is designed for the SV scopes. I had on my SV130 and bought a second for my SV80. It works great!
A worthy investment
Works perfectly with my SVX102D. Superb optically and mechanically. Using with full frame Sony mirrorless camera.
