Noel has just processed this one taken a while ago at the NFO. This is the open cluster M52 and lying nearby is the well-known emission nebula – the Bubble nebula. You can see that the Bubble nebula sits within a vast region of emission nebulosity.
This image was taken with the Sky 90/M25C combination and is made up from 4 hours 10 minutes worth of RGB data and 6 hours and 25 minutes of H-alpha. There is a great deal more emission nebulosity to be found off the right hand side of the frame, and I will probably try to capture this later in the year using the Hyperstar III. This should hopefully take a lot less time than the 10 and a half hours the Sky 90 image required.
