The Pelican Nebula with new data
I originally publish this nebula image at December 2016. After that, I have shot some very high resolution material from the same area of sky and I decided to upgrade my old image with better data. I'm kind of happy with the result, especially the details in dark nebulae are much sharper now and shows the complex structures of unionized gas and dust. Main reason is the long exposure time used, for H-alpha alone, there are 30 hours of exposures. Total exposure time is around 60 hours.
The dark nebula in the upper part of the photo is the gas bridge splitting visually the Pelican Nebula and the North America nebula so that the they look like two separate nebula. In reality they are actually a one large emission area.
