Yeah, it is supposed to be clear tonight but it’s not looking much like it at the moment. Fingers crossed. It is supposed to clear tomorrow too.

As far as exposure goes. I’m using 3mins @ iso 400. It’s bit of a tried and tested exposure for me. 800 is a bit of a colour eater and beyond 3mins I start getting amp glow. I have used 800 on some feint targets on my C9.25 reduced by 0.63 and it seemed ok but not with the f/4 newt. Having said all of that, at those settings and with the STC Duo, getting anything really decent takes 7 plus hours and more often over 10.
