Description

NGC2403 is one of the attractive galaxies in the Northern Skies and a rather bright one - which makes it possible to even grab it during stronger moonlight. What my intention with this image was is to find out how much one can get out of a RASA11 with very long exposure of the same target. My total exposure time was over 23 hours with a ASI183MC camera - and I think that is more or less the limit of what one can get out of this combination und suburban skies. Fortunately the seeing was always very good - on average around 1,5-1.7 arcsec. The sky darkness however suffered from the moon and never got better than 20.5
