I have a 250mm, 10" Skywatcher dob, and use with astronomy club belong to for schools and scout/guide group presentation
Very clear images of rings of Saturn, Jupiter, Orion Nebula
Been in Southern Hemisphere, around the CRUX, Southern Cross able to observe Jewel Box, Omega Centuries globular cluster,
Been a manual scope, recommend getting a right angle spotting scope, and I also use laser pointer and just lay along dovetail mount of the spotting scope, to aim the dob at object you want to observe
Also with the dust cover, take off the small cover, and attached some Baader on underside of dust cover, and you can also observe the sun
Have included pic of my dob at a recent public viewing night with my club
Also image of 2012 solar eclipse
Where I was only had 80% eclipse
Cheers
John
