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 🙂
Use of my images
Could I please re-iterate: None of my images are available “free of charge”. Please take a moment to look at the “Image Agency and Copyright Notice” section. Thank you.
