Not such good seeing this morning but at least I can map the spots!

Another clear night last night – Bizibilder managed 2h 20mins on the witches broom. My first go at this subject and it seems to have come out OK. I did lose a couple of subs to a small cloud that floated past which was rather annoying!
This nebula is just one part of a huge area of nebulosity in the constellation Cygnus (The Swan) – it is actually the remains of a supernova that exploded around 7000 years ago and is about 1500 light years away. The bright star is 52 Cygni and is much closer – only about 200 ly away – is has nothing to do with the nebula itself. All the background stars are part of the Milky Way.

One tiny part of a massive nebula – known as the North American nebula, Mexico region (due to its shape) or sometimes called “The Wall”. It is in the constellation Cygnus (The Swan) and is more or less overhead from the UK during the late evening at this time of year – unfortunately it is too faint to be seen with the naked eye. It would take about 6-8 images of this sized view to cover the whole thing:
2h 15 mins in 5 min subs, 36 flats, 25 darks and 32 bias. ED120 APO with reducer, modded 1000D, ISO 800, guided.
