My second attempt with RASA8. It is impressive what this small scope can do in seconds. Over two nights I used 30 secs subs to capture M31. The subs could have been even shorter (15 secs?) to avoid the burn out of the core. The scope performs very well on iOptrron's GEM45EC and with Celestron focus motor it is easy to get good focus from the controll room in the garage. Missing now are clear skies! Comments are welcome!
