Problems with ice of dew somewhere, had to heavily crop this to remove rings and artefacts. Strange colouring also part of the problem. Not great!

Never noticed this one before. Very close to the pole so easy guiding as nothing moves very much round there.

Bad planning in that the object went behind the observatory roof after only 5 sets of exposures. Not great but better than expected though.
Good quality flats make such a huge difference. Much easier to process, especially when using the reducer.

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.

Lost some subs due to clouds. Need more subs.
