I think the soul of this post was rekindling that curiosity with another complimenting passion. The love for watching heavenly bodies and examining them through the lenses both have different angles that go well. I can appreciate the enthusiasm and drive for wanting a better gear to do something you really want. Heck, I starved myself to buy me a graphics tablet when I just wanted to do digital art.
I'm sure the money to get your new equipment was the easy part. Learning how to use it and maximizing your full potential for astrophotography was main challenge. These shots are getting better and no doubt you'd be able to rival professional astrophotographers soon.
