Deneb and Sadr in Cygnus 2 October 2011
Getting a little late in the year for this target now, but after five or so clear nights on the bounce, with night time temperatures hovering around 18° C (not good for the sensor!), the transparency was getting a little suspect, so I left off until last night when I noticed an improvement. Got started a little late and, desperate for something to point at, I picked good ol' Cygnus. Just managed 19 subs before it was too low in the west. There was some pronounced horizontal banding in this that I (or more precisely, Noel's tools) struggled with, so a little blotchy in places, but overall I'm pleased considering the low number of subs.
Nikon D70 modded, 55-200 Nikkor at 70mm (full frame), f5, 1250iso, Baader Neodymium filter.
19 x 4 min, unguided EQ5
Darks, flats and bias
Stacked and processed in DSS and CS5, with a little help from Noel's tools.
