مصحح المجال TOA-35 لتلسكوبات TSA-120 وTOA-130N/150B (TKA31582)

My TSA-120 images used to have soft corners, but this flattener sharpens everything across the 40mm image circle. Stars look like tiny pinpoint dots now instead of little comets.

Finally getting pinpoint stars across the whole frame with my TOA-130, that 40mm image circle really makes a difference for framing. The correction is so clean I can see 2-micron star profiles even in my wider-field shots.

I wasn't expecting the 40mm image circle to make such a difference—my full-frame sensor now has sharp stars all the way to the edges. The center star resolution is spot-on at 2 microns, just as described. Only wish it came with a slightly longer thread for easier camera rotation.
