Hi Brent, glad to see you're having a wonderful time exploring the skies. If you think M7 is amazing, have a look at the Wishing Well cluster in Carina (NGC 3532),
it's one of my favourites
.
Also, have you spotted Omega Centauri (NGC 5139 - the largest glob) & M22 glob in Sagittarius yet? They are
amazing as well.
Keep a log book - you'll be glad you did. The more you look and push your eyes on these objects, the more you will see. I had a 6" dob and it was amazing what my eyes could eventually pull out in detail, and now I've got my 10'' dob, it confirms nicely what I pushed my eyes to see. You can add notes into your log of what details you see - dark lanes, shapes, resolving clusters etc. As Ron said, the more you see, the more you can add to your log as you're eyes improve. Log books are a great journeys to reflect back on.
There are books available to help with observing (explains what details to look for). I have a couple at the moment that I won't part with for quids.
Here is a link to understand seeing and transparency
