I wish I could hit those low temps you're running at, because I'm wanting to do longer subs than I have in the past but anything longer than 5 mins is peppered with hot pixels, even at -20. The lowest I can get the camera to do is about -24.5, which leaves the cooler running at 95% load.
Good Stuff Eden, so you have a Mono then, prob why there such a different operating specs and best settings - All the technicalities I have minimal experience at the moment to be honest ?
Re: - 24,5 degs running 95%. do you mean the camera is running at -25 below ambient or 25deg below 0deg ?

It's an interesting beasty to process, really strong inner region and very faint outer.
Quite tricky to balance.

Thanx Justin, Yeah the inside needed carefulness to keep the contrasts from exasperating; tho the transition of the fainter glow into the background early in proc, I seemed to have fluked so, am pleased with it as it is
