Thanks JA. Its fairly close to Eta Carina surprisingly but nothing else in that field except a lot of stars so it definitely gives the impression of vast space.

The Ha is quite well exposed its the O111 which is super faint. So it would take probably 2-4 hours of O111 to show much. Its mostly just a ring around it in O111. I did take 40 mins of O111 but I couldn't get it to show through.

Thanks for that. Its a nice long focal length object.300 second exposures on the QHY600m 2x2 retained star colour and I was happy about that as CMOS can lose star colour easily being so sensitive. The guiding numbers at times seemed quite bad and I was surprised initially to see perfect round stars. It must be the PEC curve causing some larger guide errors but keeping it on track. Clear skies, no wind, conditions were ideal.

More exposure on O111 would be the go as there is something there just very very faint. I have 40 minutes and I did manage to see what it was but just couldn't blend it in and show it. Too weak.

No, I think this is a target you could image from home as its a Ha object mainly. The RGB stars would need a decent dark night though.
