Category: Astrophotography Accessories

This full frame field flattener is made specifically for the SVX152 with the Stellarvue FSV35 3" focuser. 

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.

This flattener can work with former Stellarvue 152 refractors that use a 3.5" Feather Touch focuser with this adapter.

Jason J. ★★★★★

Spent two clear nights dialing in the spacing and the star shapes across the full frame are finally sharp corner to corner, exactly what I needed with the FSV35 focuser. The M48 camera side threaded on smoothly and the whole setup feels solid.

Lily P. ★★★★★

The M48 thread made attaching my camera straightforward, and the stars in the corners of my full-frame images are now perfectly round. I’m thrilled with how much sharper my astrophotography looks with this setup.

Ellie ★★★★★

I was a bit worried about getting the backfocus exactly right, but the M48 threads made setup straightforward. Stars are crisp edge-to-edge in my full frame images now.
