مسطح 0.93X لتلسكوبات FOA-60 (TKA28582)

Waited a few clear nights to test the flatness across the full frame, and the stars look round all the way to the edges now, even with my larger sensor. The reduction to 495mm gives a slightly wider field than I expected, which is perfect for framing some of the larger nebulae without losing too muc

Installed this on my FOA-60 and the 10-micron flatness across the entire frame really cleans up the corners in my astrophotos. It's nice to have the focal length drop to 495mm, making framing easier without losing image quality.

Tried this with my FOA-60 and the stars are finally sharp right to the edge of my full-frame sensor. The 10 micron flatness across the whole image circle is a huge improvement over my previous setup.
