    Celestron RASA 11 on CGX-L Equatorial Mount

    DESCRIPTION

    The Celestron RASA 11 is a wide-field astrograph optimized for high-speed deep-sky imaging. It features a 620 mm focal length and a 43.3 mm optimized image circle, suitable for full-frame sensors. Its rare-earth 4-element optical group ensures perfect correction of coma, curvature, and chromatic aberration.

    The Ultra-Stable Focus System with linear ball bearing suppresses image shift and mirror flop. A MagLev fan enhances cooldown with filtered airflow. The system includes M42 and M48 camera adapters and a multicoated optical window.

    The CGX-L equatorial mount supports 75 lbs and features 144 mm worm wheels, dual dovetail saddles (CG-5/CGE), integrated PEC, and remote-friendly design. It supports CPWI, SkyPortal, ASCOM, and is ideal for observatories or mobile dark-sky imaging setups.
