A little snowy astrophotography

February 13, 2016  •  Leave a Comment

Tonight is the first opportunity I have had to use the telescope in over 2 months.  Although we've had a couple of clear nights, they have either been inconveniently in the middle of the work week, or a cold night after a warm day, so my CCD would just frost up anyway.  Tonight was fairly clear, but the transparency was poor, so focus was an issue.

I just took a quick crack at the Christmas Tree Nebula region.  After 2 hours of exposures, it's clear that I need better skies and a much longer duration to get a good result on this one.  I'd queued up to take some 10min subs, but the guider stopped working and when I went outside discovered that it was snowing.. time to call it quits and just take -25 darks for the rest of the night.

It's also becoming more and more evident with this camera that I need to start taking flats.  There's a pretty obvious gradient appearing in the images that I need to flatten out.
