Sh2-119 in Ha

Wow! Fire in the sky; this is getting exciting.

Is this target so faint that you need 1 hr subs??

Just the OIII - it's strong in Ha and SII. This is a 30min OIII sub and there's not much there!

That really is faint. Is that a gradient in the bottom corners?

It is faint. I don't think that is gradient, I believe that's real signal - but with just the one sub to play with I have not given it much attention. It is possible the Moon was interfering and that is the reason why I aborted the OIII sequence in the first place
