Hi,
I'll be using it with a 10inch F4, so the 4.6 micron pixel size, 80% QE in Ha, large well depth, seem a good match with the F4.
Price is actually not too bad especially if it means acquiring data faster given our super reliable cloudy skies in Melbourne.
The issue with the TEC cooling actually does explain the weird pattern as reported here with the Ha flat.

Not sure how accurate reports are that the qhy version has better control of the amp glow.
