Nick Smith Posted January 7, 2017 Share Posted January 7, 2017 (edited) Hi all Here are a couple of images from the 4th using the C9.25/Hyperstar ASI1600MC-cool combination. I got home from work late and set this up quickly and let it run. This is 334 30 second subs. so well over two hours total integration time. I packed in after the meridian flip as I had to get up for work in the morning, though it was clear all night. BTW, anyone thinking of getting a Hyperstar, do not get put off by horror stories regarding collimation ect. If (like me) you are used to collimating an SCT at focal lengths of 10 meters plus for planetary, adjusting the Hyperstar at 540mm will pose no problems. I have only adjusted it once and I have a pretty good stars up to the edges of the frame. Anyway, let me know what you think. This deep sky stuff is very new to me and any advice would be greatly appreciated, I really do not know what I am doing when it comes to processing. I have attached two images; first the whole area at 50%, and second a full size crop of the Horsehead itself.
