M101 and companions - C11 Edge + Hyperstar
« on: 2012 February 05 05:53:57 »
Hello everyone,

This is the first photo I processed completely in Pixinsight from data reduction to post processing. Only the finishing touches are made with CS5. This is also the first photo I am posting here.

I am working on this since the other day and I am not able to judge it anymore. I am not completely happy with it but I need a break now :) I need to work on noise reduction and maybe I will re-process it from stacking onwards.

I guess my focus was not dead on during the exposures. I also see  elongated stars in the corners. Anyways, here it is:
