Eta with the QHY9.
5*5Min luminance and 3*100Sec each RGB taken with the ED80 with a 0.8 reducer/flattener.
Guided with a QHY5 in a finderscope.
Mount: EQ6/ST4.
First pic the full field.
Second pic a full res crop.
Normally I am quite happy to see images of well imaged objects over and over again buuuuut seeing Eta Carina shots over and over again for the next several months is certainly gunna test me... God give me strength
The image did look good.. But more exposure never hurts... 20hrs on some targets in my opinion isn't enough.... You have to draw the line somewhere, but I think with the quality of amateur mounts these days, doing multiple night imaging runs is not out of the question for anyone... I don't class an image as "Finished" until its hit 6hrs, even then I've been pushing to 9hrs recently, and as far as 22hrs on one image..
That's a nice image Martin. Things are going well for you.

Thank you Mike
Yes i was thinking the same, and will move on to the next target

Yep after a certain amount of time you will not be getting any better pictures and that is where the line is.
The dimmer the object is the more exposures will do good

Thank you David, the QHY9 is a good buy, as all 8300 based camera's are.
Just wish i had the money to buy one a lot earlier.

This is not quiiiiite true Alex...it is mostly due to the fact that most of us use small aperture, large focal ratio scopes, we just need more aperture with FAST focal ratios, here is irrefutable proof:
Yes that is true indeed.. but while im imaging at F/6 and slower, I'll stick with saying "more data needed" as collecting more data is cheaper and easier than collecting a big fast optical system...
Marc's results with his C11 Hyperstar are a perfect example I guess.. 11" F/1.8 setup, doing beautiful shots of IC434 and M16 with just 30x30sec subs..
