The Virgo/Coma galaxy supercluster

12 frames using the Hyperstar III and M25C camera with 2-hours of 10-minute subs per frame.  Also a 200mm lens with M26C camera 2-framer using 15-minute subs and 5 hours per frame.  So total integration time is 34 hours 🙂

Kemble’s Cascade – Akira Fujii-effect version

Here is a 4-frame mosaic of the Kemble’s Cascade region taken with the Sky 90 array and M26C OSC CCDs. I have used the Akira Fujii effect to enhance the brighter stars.  This actually means deliberately bloating the brighter stars … Continue reading
