Description

Here's my stab at the recent comet gracing our skies.

This was a real challenge to capture well with my mono set-up.  My plan was to cycle 30x60s LRGB captures without autofocussing to keep exposures at tight to each other as possible - this worked really well for the comet overall but it was very apparent that my filters were not parfocal, exhibiting what looked like severe tilt in the G and B in particular.  I used these subs for the comet and then a few days later took new exposures of the same starfield, with the same exposure length and same number of exposures, so I didn't feel tooooo much like I was cheating!
