Combining a precision optic with a full-featured GoTo mount, plus a suite of useful accessories, the iOptron Photron 150mm f/9 Ritchey-Chrétien Catadioptric GoTo EQ Telescope (RCT) is a complete system ideally suited to visual observation or astrophotography. Mounting the superior optics of the RCT on a fully motorized equatorial mount allows users to accurately track objects for long periods of time without the field rotation that happens when using alt-azimuth mounts. Without the field rotation, long exposure times of several minutes can be used without star streaking or blurring. Added to the optical tube assembly, mount, and sturdy tripod, iOptron includes a precision electronic focuser, an eyepiece and diagonal, and a finderscope and bracket.
