Hi all, this is my first time here and could I please have some advice. I own a celestron cpc 925 at the moment. I have been thinking about up grading for a while. Do any of you own the following scopes, Skywatcher skyliner 400p goto flextube bob or an Orion skyquest XX16 gototruss tube. I have got some great advice from Carl from scopes and space so far but need to know more before I spend my hard earned cash. What I like to know is how would the image be through them compare to my Cpc and how portable would they be? Any info would be great. Thanks again.
