Very bad focus and some field rotation.
NGC 7635 Bubble Nebula (C11) with 460EX
First real LRGB image with the new 460EX. Still need to improve processing. I have some Ha from previous night to add in too but not sure how to do it.

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.
