How long was each sub-exposure?

Thanks H. 5min subs. Got the temperature compensation working with the FSQ. Focused once around 6:00pm then stopped at 1:00am. Still in focus after 7h and a 6c temperature drop.

Thanks mate. Yes Sii requires a very fast system.

Thanks Paul. I guess I'm used to capture data a lot faster than that. An obs and permanent setup sure would be great.

Thanks Rick. My other target was M16, but it's worse. I have other channels on Eta shot with the same scope. Ha, Sii and IR now. Might try to do a funky blend see what comes out. I haven't got any Oiii yet. Next clear night.

Thanks Rex. Not many Sii only shots around. People tend to do tri-color straight away because they use filter wheels I guess. I shoot the same channel all night until I get a good pic.
