11-inch RASA V2 astrograph

The 11-inch Rowe-Ackermann Schmidt Astrograph operates at f/2.2 with a 279.4mm aperture and StarBright XLT coatings for wide-field deep-sky imaging. Its 0.41 arc-second resolution captures detailed celestial structures in short exposures. This optical tube is built for serious astrophotographers who prioritise speed and field coverage.

CGX-L mount capacity and tracking

The equatorial mount supports a 75 lb instrument load on 2.75-inch tripod legs for vibration-resistant stability. Tracking rates cover sidereal, solar and lunar motion with a high slew speed of 4°/second. Permanently programmable periodic error correction and All-Star Polar Alignment maintain precision during long integrations.

Imaging train and software requirements

The 4.48-inch eyepiece format demands compatible cameras and correct spacing for the flat focal plane. Buyers who need visual observing or planetary detail should choose a different design. Verify your imaging sensor size, back-focus budget and control software compatibility before ordering.
