Celestron C11 XLT + Starizona Hyperstar

Written by in Equipment on

My main instrument is a Celestron C11 XLT, fitted with a Starizona HyperStar. The HyperStar brings the focal ratio down to f/1.8, turning the C11 into a serious light bucket.The C11 is equipped with a ZWO ASI2600MC camera and is mounted on a Celestron CGX-L mount.More details:Telescope: Celestron C11 with Starizona HyperStar, f/1.8
