Z61 專用新款可調式 Flat61 (P-FLAT61A)

Corner stars on my Z61 are actually round now instead of smeared, which is exactly what I was chasing. The 1:1 flattening ratio pairs perfectly with the scope and the 48mm thread made the whole swap painless. First clear night out and I couldn't stop zooming into the corners.

Swapped out my old flattener for this and the corner stars on my Z61 are finally round all the way out. The 48mm thread lined up perfectly with my imaging train and the 1:1 ratio gives me a nice flat field.

Got the 1:1 field flattener for my Z61 and the stars in the corners are finally round instead of smeared. Screwed right onto the 48mm thread with no adapter fuss. First clear night out I noticed the difference immediately in my subs.
