CCA-250 (Modified Cassegrain Telescope)

I've been struggling with coma in my old astrograph for years, but this scope delivers pin-sharp stars right to the edge of that 88 mm imaging circle. The modified Ritchey–Chrétien design really does make focusing and framing so much easier.

The flat field across that 88 mm image circle is the real deal—my stars are pin-sharp all the way to the corners, even with my full-frame camera. It's a heavy beast to balance, but once it's dialed in, the views are just breathtaking.

Finally got this set up on my mount last night and the diffraction-limited stars across the full frame are just stunning. The build quality is clearly meant for serious imaging, not casual observing.
