SH2-1
(
Sharpless 1
)
This nebula is a very large blue reflection type of nebula with a smaller red emission in the heart of it. Because of the size of it, you need a good field of view to capture it all. This nebula has some HA in it so you can use a hydrogen-alpha filter which should help pick up more contrast. However, this object can be done using standard LRGB filters. To capture the entire nebula I had to rent time from Cherry Mountain Observatory and had David Plesko setup the run for me. NOTE: the RGB was binned 2x2
