Sh2-157 The Lobster Claw Over Three Nights

[Budgie1]

I started on SH2-157 on the 24th Nov as I'd never got around to imaging this one, and thought it was about time.

On the 24th I managed 30x 300s subs with the 3.5nm Ha filter and 20x 300s with 4nm Oiii filter before the clouds came. The following night it was looking good and I managed another 10x 300s Oiii Subs and 30x 300s with the 8nm Sii filter, giving me a total of 7h15m integration.

When I stacked and processed the images, it was obvious that the Sii subs were trash due to high cloud, there was just too much to make them usable.

I didn't get another chance to re-take the Sii subs until last night (30th Nov) and managed 25 good subs, before the clouds came over, and that was enough to create a good stack to add to the Ha & Oiii images to produce this.

A total of 7h 5m of 300s subs, taken with the ZWO ASI1600MM Pro set to -10°C, Gain 139, Offset 50 and attached to a WO Z73 III with adjustable FF.

C's & C's welcomed, as always.
