IC434 Horsehead Nebula near Star Alnitak - 8-10/12/2010 (Cropped & re-processed 3 night stack)
The final cropped stack after 3 nights of light gathering for this object, but not processed until early 2012 and now reprocessed in late 2012, to be less red dominated, prior to posting this on my AstroBin site. This follows my initial attempt at this object 14/11/2010. Also see uncropped version and the incremental images from the three separate nights.
The much delayed processing of this shows the capability to revisit earlier 'gathered light' either because you've learned new skills or because gathering the light is a time dependent exercise, but processing it is much less so. Gather when you can and process at you leisure!
