This is the result of 60 x 30-second subs on the Hyperstar 4 with the C11 and a secret ingredient optical device. Still plenty of noise even with 60 subs, so it looks like I’ll be needing nearer 200 subs to get the noise down. However as these 60 subs took up 3Gb, and then de-Bayering and processing added another 9Gb, it looks like this data will be needing its own hard drive just for this one image!
