First Tamron lenses are not exactly high quality, never have been. They have made improvements and come up with some ok lenses at specific focal lengths. You haven't reached the limit of the hardware, I don't think you've tried to stretch your limit of how to use it. I've done a lot of good shots with a 105mm lens, 90mm isnt problem. f2.8 is part of the problem here as is overexposure. You aren't capturing nebulosity here I can see. The stars are obviously way over exposed ending up with white disc cores. Lower the exposure time and/or stop the f-stop. If you're expecting nebulosity or milky way up the iso too. Try that and the stars should tighten up and the globular cluster will start to gain definition and overall stars should gain some colour back. Plus the processing is just way off overall, imo dss and gimp/photshop are the wrong tools especially for newbies. They can be used to good effect but its clear you don't, sorry.

Don't be sorry. Honesty is what's needed. What would be good tools for this newbie? I'll give your suggestions a try the next decent night we get. Just for the record the Tamron 90mm 272E is a superb lens when attached to my Sony Alpha a58.
