Great going Mario. Don't be put off, just getting your tracking going well for 2min subs puts you in range of all sorts of objects. The astroimaging mountain is big however, and you're still in the foothills (but with plenty of experts here to help you up). Getting these basic foundations working reliably is so important for your sanity later on.
As you've already figured out, if you repeat this exercise on a moonless night (or even better dark sky site) your data will be a lot easy to push.
Some other things you'll come up against soon:
- need for flat frames if you're stacking frames with significant sky background (you've got signficant vignetting coming through there)
- possibly consider a light pollution filter if you'll be regularly shooting from the 'burbs
- processing (I'm starting to think no-one ever gets to the top of THAT mountain after seeing Martin Pugh post re-works recently...

)
I think you've done great for a DSO shot from the 'burbs in strong moonlight!

Stop being so hard on yourself.
