Bummed
Couldn't figure out what I was seeing in calibration frames. Then distorted lights. Turns out the camera had copious amounts of condensation (inside and outside the sensor). Tech at QHY asked me to return the camera after I sent them the images. A desiccant tube was included, but the images were so bad I thought a hairdryer was needed (not really). I returned the 268M. Waiting to try the ASI2600MM Pro. We'll see.

Awesome camera
This is a huge upgrade from my 1600... much better than I expected. Zero amp flow and a huge full well along with so little noise makes this thing incredible. The 268m actually has only 12.5 mm back focus from the front of the camera. I use a Newtonian and that 5mm is enough to get me perfectly spaced for my coma corrector. A subtle point but huge considering most cameras use that 17.5 mm back focus as standard.

Fine
I pre-ordered QHY268M at beginning of February and got it late March. Pretty fine for pre-order stuff tied to launch where quantity is limited.
