Hi guys, thanks for the comments.
Yeah, its a single sub of 8mins, i am messing around with times etc, finding my feet. I am finding that anything over 4mins, starts getting a woefull amount of hot pixels so, but anytime i stax images i endup with this tiff, that looks woefully over exposed, so i am seeing how far i can push it.
any advice on that score, greatly recieved.
