Description

My first stacked DSO! Just had to start with the Horsehead-- been waiting years to give it a go. Need to learn how to "process away" that wide halo around Alnitak. Also, I suppose more integration time would help reduce noise further. I added 15 darks to the 19 lights.

Much to learn. Maybe I'll hit some LRGB next. Although, I would like to move to a target with no overly-bright stars!
