Description

M 81, my first success with the Celestron EdgeHD 9.25 and the CGX mount. I'm still struggling a little bit with the collimation. As far as the processing in Startools is concerned, I always have difficulties to find correct settings for the wipe module and to get decent colours. I just wonder where the superbe colours I often see in similar objects come from.
