M83, 135 minutes total, over 2 dates

[tornado33]

Hi. I tried stacking my recent M83 image taken the other night with Houghys cooled DSLR, with an earlier image set taken back in August 2006.
So its a total of 15x5 mins ISO 400 cooled, and 6x10 mins ISO200 uncooled.
I found a cool stacking function in IRIS called Global Matching, that is similar to registar that rotates and aligns automatically, great for images taken at different dates. Ive masked it as well to preserve core detail. This is the deepest M83 pic Ive ever assembled.

Wow!
Nice! ;)
This seems like a very populat target, maybe we should have a contest with the target being M83?
