Applications & selection
ATR2110C applications
One-shot colour deep-sky imaging
The colour SC2110 sensor captures broadband targets without a separate LRGB filter sequence.
High-resolution galaxy and lunar imaging
12 µm pixels balance image scale and detail for appropriately matched telescope focal lengths.
Photometry and time-series imaging
12-bit acquisition, 72 dB dynamic range and regulated cooling support repeatable quantitative observations.
When to choose this camera
Choose the ATR2110C when your telescope and target benefit from APS-C class, 23.2 × 14.6 mm sensor coverage, 12 µm sampling, two-stage TEC, ΔT up to 42 °C and 380–690 nm response.
