40% is not bad QE for Ha.
That original Facebook link just keeps scrolling on and on. Is there a specific link to the new camera announcement?

QHYCCD are still in beta testing that camera and no official announcement has been made. Re Ha QE, I totally disagree. 40% QE is way too low. See the specs chart for the QHYCCD 367C which is the 810a chip. See this link.
