Calibrated and Stacked with Maxim DL; Processed with CS4
This is a re-process of previous image. I added flats, and I finally figured out how to do a one-step LRGB combine in Maxim. Also experimented with DDP to do initial stretch; this one used low-pass kernel filter. I then stretched the crap out of it in CS4 to see how far I could go.
