I have been looking at new camera specs and decided it was finally time to retire the old QHY9. So last week I purchased a QHY268m, a new 7 pos filter wheel, a full set of Antlia filters, and a new OAG.
I was looking forward to seeing what it could do and luckily got some clear nights to test it out. I am really happy with the robust bolt through attachment system, and not having to swap out filters for narrowband.
I have some work to do with flat calibration, but other than that everything seems to be in order. I honestly think both images look similar to maybe 2 or 3 times the integration with the QHY9, I don't have any dead columns to deal with, and I am just very happy with how things are looking.
