Very nice and the stacking technique clearly helped. What software do you use to stack these?
Canon 600D unmodified. Astronomik CLS-CCD filter (reduces impact of sodium lighting). Canon 135mm f/2L at f/2. ISO3200. 50 shots stacked of 5s exposure each.
I only took a fixed tripod so had to keep exposures short to reduce the impact of star trailing. The fizzy blob above the comet is Andromeda galaxy. The two should be very close in the sky around now, if I get another clear night I'll give it another go.
