Having some trouble focusing my Dobsonian. I’m seeing objects but there very blurry, I’ve collimated my telescope already, adjusted the focusing knobs (made sure the screw was loose to be able to adjust), have tired with both 25mm and 10mm 1.25 eyepieces during the day and pointing at bright objects that are far way. I’m not sure if it’s just beginners struggle and eventually I’ll get shard images, but any tips would help! Thank you.
