Description

Sorting the new Stellarvue. Oh, and my own ability to take a picture...

I experimented with shooting shorter exposures at lower ISO in an effort to reduce star bloat and get more dynamic range out of the Pentax. I am not sure if it had any effect because I haven't shot this combination before.

I usually shoot ISO400 and exposures in the 4-6 minute range. This was shot at ISO200, and 150 and 180 second exposures.

Best 95% in DSS, so 4 hours, 16 minutes net total exposure time.

Description: Complete reprocess applying some newly learned techniques for stars and better color balance. I am learning things so quickly now that every time I process a new image I want to go back to the last one and fix stuff!

Description: That last one was a little too saturated dontcha think? I fixed up some stars while I was at it.
