Celestron 11" Rowe-Ackermann Schmidt Astrograph (RASA 11) OTA with Telrad Base - Pre-owned

This Pre-Owned Celestron 11" Rowe-Ackermann Schmidt Astrograph (RASA 11) is a highly specialized imaging telescope designed exclusively for astrophotography, not visual observation. It remains in excellent condition, with only a minor, barely visible dent on the OTA that does not affect performance in any way. This OTA features two dovetail attachments for versatile mounting options and an attachment point for a finder scope (finder scope not included). A Telrad base is already installed for precise alignment—an added bonus for astrophotographers.
