Applications & selection
ATR533C applications
One-shot colour deep-sky imaging
The colour IMX533 sensor captures broadband targets without a separate LRGB filter sequence.
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, 87 dB dynamic range and regulated cooling support repeatable quantitative observations.
When to choose this camera
Choose the ATR533C when your telescope and target benefit from 1-inch square, 11.31 × 11.31 mm sensor coverage, 3.76 µm sampling, two-stage TEC, ΔT ≥45 °C and 380–690 nm response.
