Hi folks,
Firstly a big thankyou to Cometcatcher for sharing his knowledge and posting the guide to comet stacking and to Rat156 for raising the bar on technique to strive for with this subject.
This is taken under dark skies in country Victoria, thanks to The Bluester for assistance throughout the night.
I really wanted to try this, but until saturday morning I had no real idea of what to do until I saw Cometcatcher's posting. This is my first attempt at comet stacking and merging/processing.
Crikey it wasn't easy guys, esp on the mac without sigma stacking available!
Anyway, here is my result, thanks for looking. High res here...

14x60 secs for the comet, 10 x 120 secs for 47 tuc, darks, flats and a whole lot of PS in postproduction.
