On your 135mm shot, there is a "fuzzy" star to the right & below of the 
comet.  It's the globular cluster M14, where H-B just "went by" a few 
days ago.

 I noticed you went 15 min with 135mm/2.8 lens on hypered Fuji SHG400.  
Was it stopped down, the image looks pretty well corrected in corners.  
(What lens brand is it?)  I get a pretty good exposed neg 12-15 min 
@f2.8 on unhypered Fuji SHG400.

 I was tempted to use it myself on evening of Oct.10, but opted for the 
Fuji SG800+ (which has good blue response & finer grain).  Unhypered, 
the 800 supposedly is 1 stop faster than the SHG 400 (say 5-7 min 
@f2.8).  So, you shouldn't be unhappy with no more SHG400 - just use 800 
(as long as the comet shows a lot of bluish ion tail).  I was impressed 
with the 800's dynamic range (the SHG400 is known for this) on my 300mm 
FL Schmidt Camera shot (Oct 10).  I got inner nucleus & curved jets, 
like on your narrow angle shot.
