Description

B33 or famously The Horsehead Nebula. Roughly 1375LY from Earth and approximately 3.5LY in radius is one of those rare nebula that actually resemble its namesake. This image is cropped from a wider field that includes the Flame nebula, but I drizzled and cropped to get tight on the Horsehead to highlight this area for now. I love the Ha data in the area as it looks like a curtain, ribbon like. Not having a lot of time to image this as it transits the valley, I did the best I could with the time available. The Ha data is very strong and the 7.5 hours I collected was more than enough. 

Its a common target, but it took me years to attempt as I am afraid of the brutal star Alnitak! Once I figure out how to make it look good I will publish the wider field.

Thanks for looking!
