Applications & selection
G3M664C applications
Lunar surface imaging
2.9 µm pixels and 4.1 MP (2688 × 1520) resolution support detailed lunar mosaics and close-up imaging.
One-shot colour planetary imaging
The colour IMX664 sensor provides a direct RGB workflow for planets and the Moon.
High-speed solar and occultation capture
Fast acquisition supports brief events and solar imaging when the telescope uses a correctly specified solar filter.
When to choose this camera
Choose the G3M664C when 91 fps acquisition, 2.9 µm sampling and the IMX664 sensor match your telescope's focal length and seeing conditions.
