I have just found a huge pile of images that I didn’t process properly the first time around, so I have just spent all morning processing just a few of them.
This first image shows the bright blue star Merak to the left of the frame and the asterism known as the Broken Engagement Ring towards top-centre.
This is a vertical 2-frame mosaic taken on the Sky90 array using the M26C OSC CCDs. Each frame is approximately 4-hours of 10-minute subs.
