First chance to try out the new 460EX properly.

A “mucky” night with low transparency. Lots of star bloat but the camera has almost no noise at -10C. Processing still needs some work. Too many very red stars. Could be caused by the DS filter?

Not transparent enough tonight to image any galaxies (tried M33 but the image fogged after 2 minutes) or nebulae so a new open cluster for me.

I came across this one by accident. A lovely open cluster. 

NGC 7789 is an open cluster in Cassiopeia that was discovered by Caroline Herschel in 1783. Her brother William Herschel included it in his catalog as H VI.30. This cluster is also known as “The White Rose” Cluster or “Caroline’s Rose” Cluster because when seen visually, the loops of stars and dark lanes look like the swirling pattern of rose petals as seen from above. Wikipedia

Not great sky conditions – a little foggy.

Lost some subs due to clouds. Need more subs.

Some slight elongation of stars at left side is due to camera alignment and not coma (which has been resolved by the MPCC).

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.
