Comet C/2014 Q2 Lovejoy, 20th and 23rd of December

Comet C/2014 Q2 Lovejoy taken on 23-12-14 with my Canon IXUS point and shoot. 10x 15 second exposures ISO 400 stacked with deep sky stacker. and cropped to the region of interest, showing Phract (alpha Columba) and the comet (Click to embiggen)

Comet C/2014 Q2 Lovejoy continues to delight observers, with a partial tail disconnection event and some impressive tail twisting.

In binoculars it is an easy catch, and in my Canon point and shoot images it has significantly brightened. I made it out to be magnitude 5.8, other estimates have been around 5.6-5.7. Well into the unaided eye range under dark skies.

I have extended my comparison of the comets tail out to three days, the images are 5x180 second luminance images Bin 2 taken with  iTelescope T12 stacked in ImageJ on the comet and a MEDIAN Z project taken then inverted. North is to the top.

Resolution is 3.5 arc-secs/pixel
