Comet C/2014 Q2 (Lovejoy) on Jan 6, 2015

A quickie processing job on data taken on Jan 6, 2015 at 02:53 UT (Jan 5, 8:53 pm CST.) This is 36×45 sec ISO 1600 sub-images taken with a Televue TV-85 at F/5.6 and a stock Canon T3 with no LPS filters in the image train.

A very bright moon was out while taking these shots, but it still shows a nice tail. Just think how good it will be when there is no moonlight to hinder the view!

Comet Q2 – Big and Bright

Finally, a clear night and no trees obstructing the view!   Comet C/2014 Q2 (Lovejoy) was out and easily spotted in binoculars.  I did some 3 minute exposures and they showed it as a large bright coma and a very faint tail.   The light and dark images above are a  quick processing job on the sub-images I obtained.   Below is a star streak version of the same data that shows the extent of the coma better.

Here is all 20 sub-images I managed to shoot in a quick additive stack.  The tail is there but very faint.  There was some smearing of the pseudo-nucleus with 3 minute exposures, but I needed to go that long to get a bit of that faint tail.

Well, I got my first images of Comet Lovejoy, C/2014 Q2, but unfortunately, they were all shots that had tree branches in them.  The comet was still too low for my location at the time the shots were taken.    I have since chopped the trees down that were causing this mess, so hopefully I’ll get something better in the near future.  The above animation was all I could salvage from the images.

After the moon had set on Dec 1, 2014, I decided to let the camera and guiding run while I slept and take images of the Horse Head Nebula region.  I managed to get 33 good sub-images before the clouds messed up the tracking.

I wanted to see what this was.  It appears to be a spiral galaxy.  With just 18 sub-images, it is only barely visible.   I might come back to this one with longer exposures and 4 times as many subs to bring it out better.
