Moonlit night and hazy sky – not great conditions but the first of 2013 and a new Messier object to add to the list. Definitely needs some flats.
Have gone back to piggyback guiding because the OAG was just so fiddly to setup and acquire a guide star. Not convinced it was producing any better results either.
