Rosette nebula mono


Recommended Posts

My current setup field of view (3x2 degrees) allows at last to capture Rosette in a nice frame, so I started the HSO project. During the last two nights (the first clear nights this year at my location) I captured 5 hours of frames with a hydrogen alpha filter and here is the result. Snow and an almost full Moon made extra light pollution, but the target is quite bright and a lot of photons were captured :)

Full frame (maybe stretched a bit too much) and enlarged center.

TecnoSky 90/540 Owl, 0.8x FF/FR, QHY268M, Baader filters, 110x3 minutes, Bortle 6 sky, Moon, transparency good.
