Hi all , new to forum and fairly new to astronomy . After a little lazy research a few months ago i bought a Bresser Messier AR-80/640 . I read a review on the sky at night website they gave it 4/5 stars and said they viewed Saturn's rings quite clearly . This was one of the boxes i wanted to tick and went ahead and made the purchase . Try as i might i can't see Saturn's rings . Is a 3 inch aperture too small ? Or is there a better time of year to view Saturn ? I've tried various eyepiece combo's with and without a barlow x 2 to no avail . Anyway thinking of an upgrade and was thinking of a 8 or 10 inch dob . Had been looking at a Skywatcher Skyliner 250px , Bresser Messier 10inch dob or an Orion Skyquest XT8 plus .Anyone any thoughts on these scopes or preference ?
