Applications & selection
ATR432C applications
One-shot colour deep-sky imaging
The colour IMX432 sensor captures broadband targets without a separate LRGB filter sequence.
High-resolution galaxy and lunar imaging
9 µm pixels balance image scale and detail for appropriately matched telescope focal lengths.
Photometry and time-series imaging
12-bit acquisition, 74 dB dynamic range and regulated cooling support repeatable quantitative observations.
When to choose this camera
Choose the ATR432C when your telescope and target benefit from 1.1-inch, 14.4 × 9.9 mm sensor coverage, 9 µm sampling, two-stage TEC, ΔT ≥44 °C and 380–690 nm response.
