I imaged this one a few years ago but the seeing wasn't that great.
I was at my dark site on the weekend and its not far from Eta Carina so a good target for the early evening.
Its mostly a Ha object but there is some very very faint O111 as well. I took about 50 minutes and it looks like it would take at least 3 hours to get a decent amount of data. Maybe another time.
I was pleased with the tracking accuracy of the AP1600.
Taken with a CDK17 and a QHY600m photographic camera with 5nm Astrodon filters.
