Another Catalina
« on: 14:58:16, 08 January, 2016 »
Unfortunately weather and other commitments did not play fair with me in December :(  But last night (7th Jan) was a beauty, although it didn't clear until midnight!  So I did some other imaging, then around 5 am turned my attentions to the Comet.  Took me a little while to get set up, then I captured 10 x 3 minute subs using my Canon 350D, RAW frames at ISO800 on TS65quad telescope (420 mm fl).  Darks and flats applied and some fiddling with different stackings in Deep Sky Stacker to come up with this.  Cropped a bit to lose amplifier glow from one corner.  The Ion tail is now very faint, perhaps longer exposures would have helped, but it is fast moving - a balance between brightness and movement blur.    But at least I got something ;)

The main head area was quite bright in binoculars, and comparing it with the nearby M3 I would place it around 6th magnitude.

You've done a good job keeping both comet and stars sharp and still background looks good.
