Applications & selection
ATR533M applications
Narrowband nebula imaging
The monochrome IMX533 sensor is suited to H-alpha, O III and S II filter workflows.
High-resolution galaxy and lunar imaging
3.76 µm pixels balance image scale and detail for appropriately matched telescope focal lengths.
Photometry and time-series imaging
14-bit acquisition, 92 dB dynamic range and regulated cooling support repeatable quantitative observations.
When to choose this camera
