Southern Sky - First attempt at astrophotography

[AntMason]

Hi guys, I'm new to the forums today, so I thought I'd post one of my later shots. I've looked, there but really hasn't been much info on the forums regarding astrophotography, but I haven't gone through the back logs yet.

Anyhow, I've had my first DSLR for a little over a month now, and this was my first attempt at a night-time sky outside the city limits. Taken with 40 light frames, 20 dark frames on a T2i @ 18mm, 800 ISO, 25 second exposures, stacked using Deep Sky Staker, Post Processing in Lightroom.

I was hoping on suggestions on post-processing, such as if the saturation or exposure I added was too much, or how I might be able to utilize Lightroom to make the image sharper (tree-line aside). Any critique, of course, is welcome. Thanks in advance!
