Re: Deep sky objects are very dim!!!

Small apertures and severe light pollution ensure deep sky objects are underwhelming, if they can be seen at all. I use a 10-inch from home to observe deep sky objects, and many of them are also very dim looking due to heavy light and air pollution. You have no other choice but to go to darker skies when the moon is not shining brightly also. Then you can at least see them better. If you want to even see hints of details on the dimmer ones, you'll need at least an 8-inch, and there's many deep sky objects that are a tough one for 12-inch telescopes from dark skies too. I would look for the Messier objects and the brighter NGC objects as well. There's a number of big but bright star clusters and some nebulae and galaxies that will be worth looking at from a dark site.
