Enjoyable, but very cold session last night, bit of high cloud kicking around and light pollution seems to getting more and more noticeable for me now. Not had time to add any flats to these but quite pleased to be picking out the blue areas in the Whirlpool Galaxy:
Beehive Cluster - 31 x 45 sec ISO 1600 plus darks and bias
Double Cluster - 34 x 45 sec ISO 1600 plus darks and bias
Leo Triplet - just a final flurry before packing up so only 10 x 45 sec, darks and bias, right in the worst light pollution area at them moment
Whirlpool Galaxy - 78 x 40 sec (for some reason I changed it!) ISO 1600 plus darks and bias, heavy crop
All stacked in DSS, and stretched in GIMP.
