[BAA Comets] 2014Q2 AVI from last night

[Peter Carson]

Hi All,
Inspired by images of tail structure changes in comet 2014Q2 I imaged the comet for 2 hours last night.
I took 24no x 300 second exposures using a 100mm f5.4 refractor and ST8300 CCd between 20.32hrs and 22.33hrs.
I stacked them in groups of 3 and compiled them into an 8 frame AVI.
The AVI shows some tail ray motion, (together with passing light cloud!)
The images where calibrated, contrast stretched and aligned but not processed in any other way.
North is up and the field of view is approximately 2 degrees wide. 
See the AVI here http://www.astromania.co.uk/2014q2_lovejoy_video.htm
I will stack and process some of the images for the Section image archive.

The sky was slightly milky here in SE Essex last night but I'm convinced I could just detect about a degree of tail in 11x80 binos. My observing site is an urban area and light polluted.
