I came across this video presentation of the new QHY products that are being released.
The presenter is Michael Barber who owns a company called "Santa Barbara Scientific" and is a QHY Dealer and also a QHY repair centre for the USA.
He shows that in OCT 2020, the new APS-C Mono QHY268M camera is to be released , same specs but a smaller sensor version of the QHY600M.
Exciting news, what everyone has been dreaming of for years, a Mono APS-C camera.
