The FarPoint Bahtinov Mask for the RASA 8 is a precision focusing tool designed specifically for the Celestron 8" Rowe-Ackermann Schmidt Astrograph (RASA) telescope. Made from durable ABS plastic, this mask uses a diffraction slit pattern to generate distinctive X-shaped spikes from bright stars, enabling astrophotographers to achieve perfect focus in under 90 seconds by iteratively adjusting until the central spike aligns symmetrically with surrounding spikes. The mask mounts easily on the telescope's dew shield via rubber tabs and works equally well with DSLR cameras, mirrorless systems, and astronomical CCD/CMOS cameras, making it an essential accessory for critical focus during planetary and deep-sky imaging.
