Here's the latest offering from the Parker/Carboni deep-sky imaging factory:
This is the Markarian Chain region (centre) at the Virgo/Coma border. This is probably the biggest mosaic that will ever be made using the Sky 90/SXVF-M25C combination, as I have just moved back into Hyperstar imaging once again. So the field of view here is just under 5 by 3 degrees. The image has been left uncropped as I didn't get the third frame right, so cropping to a rectangle cuts off M87 at the bottom.
Just over 16 hours total RGB imaging time, with a similar amount of time spent on the processing.
