QHY461Pro M

SKU# QHY461Pro M

Price: $26,000.00


The QHY411/461 has both USB3.0 and 2*10GigaE interfaces. The 2*10GigaE version supports a higher readout speed.

QHY411/QHY461 have both mono and color version. The application of this camera includes astronomy imaging, astronomy photography, space object survey, satellite tracking, etc.

Benefiting from its back-illuminated pixel structure, the QHY411 has a large full well of 80ke-. And when using 2 * 2 binning, the full well can reach 320ke-, corresponding to a merged pixel size of 7.5um * 7.5um; while at 3 * 3 binning, the full well can be up to 720ke- with a large pixel size of 11um * 11um, which is much larger than any other CCD or CMOS sensor of the same pixel size. Combined with the low readout noise,  the camera has a large dynamic range advantage.
