I haven't posted an image on here is a long time, but I thought this one was interesting enough to warrant it. This is Sh2-126, a huge and faint nebula in Lacerta. The field of view here is 6x7 degrees, and it barely fits. That probably explains why it isn't imaged often. This image is Ha+LRGB. The L was used to bring out the faint molecular clouds in the foreground. Someone with darker skies than mine could probably bring them out a lot more. Total exposure time is 8h 23m, with just over 6 hours of H-alpha. All of this was at f/2.8, indicating just how faint it is.
Personally, I think it looks like a big (scarlet) letter A. This is an underrated object, and a great use of the excellent Rokinon/Samyang 135 mm lens.
