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 🙂
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.

The Sky 90 array was set on this object to see if I could pick up the 3 quasars near this galaxy. No sign!! A day later I put the Hyperstar III on the same region but only got 4 … Continue reading
Got today’s EPOD with a groundbreaking image of a Dyson sphere construction around Polaris imaged in the early hours of this morning. Thank you Jim for continuing to publish my work 🙂 http://epod.usra.edu/blog/
