Product Details

  • TAKAHASHI CCA-250 F/5.0  Modified Cassegrain Telescope OTA:

    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.

     Image/ Drawing Note: The CCA-250 OTA is shown with a full set-up for use purposes only, the guidescope, rings, plates, mount, and tripod are not included, but may all be purchased separately.
