Adjustable Flat73A for Z73 (P-FLAT73A)

Took it out last night and the star shapes are perfectly round edge-to-edge with my Z73, no more coma. The rotating adjustment ring is smooth and stays put once tightened, which I was worried about.

The adjustable back focus ring clicks into place with satisfying precision, making it easy to dial in perfect spacing for my setup. Paired with the Z73, I can finally see pinpoint stars all the way to the edges of my images. Definitely worth it for cleaner flats.

Took it out last night for the first time and the adjustable back focus made dialing in flat fields incredibly easy. Even with my Z73, the stars are pin-sharp all the way to the corners now.
