Description

The CCA-250 is Takahashi’s modified Ritchey–Chrétien, developed as a replacement to the BRC-250 and is designed with imaging in mind. The CCA-250 produces a flat field across an 88 mm image circle. At prime focus, it is a 250-mm aperture, f/5.0 astrograph. Coupled with a reducer, it becomes a fast f/3.6 telescope. The CCA-250 has a carbon fiber tube and a temperature compensated lens cell to maintain focus during long exposures. The CCA-250 also has an ASCOM compliant active focus system that enables computer control of the focusing system.

Christopher A. ★★★★★ Oct 21, 2026

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.

Alexander ★★★★★ Oct 20, 2026

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.
