Applications & selection
G3M678M applications
Lunar surface imaging
2 µm pixels and 8.3 MP (3840 × 2160) resolution support detailed lunar mosaics and close-up imaging.
Narrowband and near-infrared imaging
380–1100 nm monochrome response supports filter-based seeing control and contrast enhancement.
Solar imaging with approved filtration
Can be used for solar capture only with an appropriate certified solar filter and safe observing setup.
When to choose this camera
Choose the G3M678M when 47 fps acquisition, 2 µm sampling and the IMX678 sensor match your telescope's focal length and seeing conditions.
