Description

This full frame field flattener is made specifically for the aluminum tube SVX102T and the carbon fiber tube SXV102T-R. It is made specifically for the Stellarvue FSV3 3" focuser. 

Please note: This flattener will not work with telescopes using other focusers. 

If you are using a Stellarvue SV102T/SVR102T using a 3" Feather Touch focuser you will need this 3 inch Feather Touch focuser adapter.  If you are using an SV102T/SVR102T that comes with either the Stellarvue or Feather Touch 2.5" focuser you will need our 2.5 inch focuser adapter.  

On the camera side of this flattener is a standard M48X.75 thread. The backfocus from the base of this thread is 55 mm. So this flattener as it comes will work with a DSLR with a 48 mm t-ring. It will also work with a ccd camera that uses the M48 thread and has a 55 mm back focus. If your ccd camera uses another thread and/or if the back focus is not exactly 55 mm, please call us and we can provide you with a modified version of this flattener with the proper adapter to meet your requirements.

Violet J. ★★★★★

Didn't realize how much my stars were suffering from field curvature until I fitted this flattener—now the stars at the edges of my full-frame sensor look just as sharp as the center ones. The way it threads directly onto the 3" focuser made installation a breeze with no extra adapters needed.

Julian L. ★★★★★

Setup was straightforward on the 3" focuser, and the full frame corners came out clean across my test exposures. My stars stayed round from edge to edge, which is exactly what I needed for this tube.

Mia G. ★★★★★

Finally got my stars looking like pinpoints all the way to the edges of my full-frame sensor with this flattener—it threads perfectly onto the 3" focuser. The difference in corner sharpness is night and day compared to using no flattener at all.
