The Pelican Nebula
July 4th, 2018
This June I revisited the Pelican nebula, this time with better equipment and knowledge. I decided to shoot narrowband and HaRGB, to show the contrast between the two imaging techniques. Due to my inexpensive narrowband filters, the stars (especially in the SHO version) have some very nasty halos. I’m also not super happy with the colors I ended up having in my final SHO image, but I don’t really know how else to approach it. I do like the details and lack of noise in both images; this is a much better rendition of the nebula than any of the previous 3 times I have captured it. I currently have a ton of data on my hard drive, most of which has been processed but needs to be posted, so I’m trying to play catchup with the Texas clear skies.
