LBN552 and other dust/reflection nebulae

Recommended Posts

LBN552 appears as a small orange patch to the lower left of this image, with dark dust and reflection nebulae from the borders of Cepheus, Ursa Minor and Draco. This was a bit of a rescue job as had a bunch of problems during initial acquisition - mount lost power at one point, then auto-focus failed during the second half of the night (still dialling it in with the new scope). Polar alignment is way off as I think the pier has shifted a bit since I last used it, so lots of field rotation caused the outer 10% to be unusable once stacked. I need to make a better flats box too so this is just a crop from the centre of the image complete with dust bunnies. needs four or five times the amount of data really so the overall effect is a bit waxy at the moment, but still it is a pleasing start.
