I gave the Witch Head Nebula a go. I mounted my dslr on top of the scope with a 400 mm lens (f/5.6). Guiding was so easy compared to at 2000mm
I found this nebula hard to image as it is not very bright. The sky glow started to compete with the nebula after about 10 mins. I don't have any filters, so maybe I should do some research
A warm sensor doesn't help either.
A total of 3:50hr of data, 10 min subs at ISO 1600. Associated dark frames as well.
Stacked in DSS, processed in PS C6.
Comments and hints welcome.
