Comet C/2014-E2-Jacques
Written by Richie Jarvis   
Sunday, 31 August 2014 23:55

Tonights image of Comet C/2014-E2-Jacques taken from East Sussex with a TMB 114mm @ F/5.6 and a -30 degree C Starlight Xpress SXVR-H18, and astronomik LRGB filters whilst tracking the comet.  Combined in MaximDL and processed in Photoshop.  You can clearly see that I shot with a clear (luminance) filter first - the long white lines (stars trailing as the comet moves), and then followed up with a sequence of 2 minute images through a Red, Green and Blue filter.

One of the green exposures has a faint satellite flare just beneath the comet coma.  This happened at 2014-08-31 22:14:22GMT+0 - plus or minus 1 minute, and shows clearly on the exposure.  Another satellite also passed during the luminance exposures at 2014-08-31T21:27:27GMT+0, plus or minus 2.5 minutes - the faint white line passing to the right of the coma from top to bottom.

12 x 300 second Luminance
