Here is a composite image of M31 comprising 2 sets of Sky90/M26C OSC CCD data.
A real blast from the past. Just came across this one and tarted it up a little on Paint Shop Pro. This is the Cygnus Wall region of the North America Nebula. I cannot remember the year this was taken … Continue reading
Got today’s EPOD with the Supernova SN2022hrs. Thank you Jim at EPOD for continuing to publish my work.

From 18/01/2015 another Sky90 array image using the M26C OSC CCDs, this time open cluster NGC1817. 12 subs at 20-minutes per sub or 4-hours in total.
Image taken 24/01/2015 on the Sky90 array using the M26C OSC CCDs. 30 subs at 10-minutes per sub.
Mu Cephei sitting at the top of the bright emission nebula IC1396. A Sky90 array image using the M26C OSC CCDs and 51 x 4-minute subs. Image taken on 04/12/2012.
From 09/02/2015 using the Sky90 array and M26C OSC CCDs this is M44 – the Beehive Cluster. 29 x 5-minute subs and the Akira Fujii effect has been applied to bring out the cluster.
