Cephus region on 4x5

 Latest effort was 2 hours on Cephus on the 4x5 with a 400mm lens at f5.6.

I'm pleased with the results.  There are some errors and I look forward to refining the technique.

I have been trying to see the dark nebula east of IC1396 for years.  It finally has started showing up for me and I'm glad.

Stuff to do:
Get better at focusing.  The Lodestar is sensitive to the unfocused near IR that passes through this lens.  Thus, the bahtinov mask image is not precise.  I focused the 400 based on star size since that seemed to be the best indicator.  I will put a UV/IR filter on the rear of the lens to see if that cleans up the signal.
