The QHY461M uses the ONY IMX461 back illuminated sensor. This medium format sensor offers a large 44mm x 33mm sensor size and 3.76µm pixels with native 16-bit A/D. This QHY461M is available in monochrome only.
Building on the outstanding reputation of the QHY268M and QHY600M, the QHY461M promises to offer exceptional value for larger format cameras. Supplied as standard with the QHY461M are the QHYCFW3-XL filter wheel offering 7 x 50mm sq filter positions and the OAG-L Off Axis Guide unit.
Currently the QHY461 is available to order with a typical lead time of 14 days.
