Horsehead Nebula to Orion Mosaic

lrgborionrecolorps

I have decided to give mosaics a go. This turned out to be more difficult and complicated than I had thought. I hope to reshoot the RGB data as there was a difference in exposures between RGB filters by a factor of 100! Somehow the gain settings got mixed up is the best I can figure. Salvaging this data required a lot of work but I think all in all it looks pretty nice. I am sure there will be an updated version of this in the coming months, weather permitting.

Taken with the ASI1600MM-Cool and the Stellarvue 80mm ED APO at f4.8 384mm
