Have just bought Dannat's Polarie and am hoping to do some simple wide field imaging with it. I have read a little bit about stacking multiple images but have never seen or used any of the programs available. Nor do I have much of a clue about darks, flats, etc (I only know they exist cos I see them mentioned a lot in the Images forums).

I have two questions to get me started:

1. Recommendations for inexpensive stacking programs for Mac, and
2. A resource that will explain the basic techniques so that I don't spend hours scouring the web.

Any help would be appreciated.

Thanks

Morton
