Last night was a wonderfully clear, moon-free night, and being just about the longest night of the year meant I could get started early! The three images below were all taken with an Atik 460EX OSC with IDAS LPS filter through an Equinox 80 refractor, and processed in PixInsight.
First up was NGC1746, an open cluster in Taurus that I noticed a little while ago and thought would make a good imaging target. This is from 14 x 10min subframes:
I then moved round to one of the most iconic areas of the winter sky, and took 15 x 10min frames of the region around Alnitak, capturing the Flame and Horsehead nebulae (NGC 2024 and B33 respectively):
Finally, I tried M41, an open cluster in Canis Major. This never gets very high above my slightly murky southern horizon, but the combination of the LPS filter and PI processing did the trick from just 7 x 10min exposures:
