ToupTek Blue GPM662M Professional Monochrome Guide Camera IMX662 2.1 Megapixels Astronomy Camera

Description:
- A professional monochrome guide camera featuring the latest IMX662 back-illuminated CMOS sensor for Sony, offering exceptionally strong infrared light capture capability, large full well capacity, high dynamic range, high sensitivity, and ultra-low readout noise for outstanding performance in planetary, solar, and lunar photography.
- The GPM662M camera possesses an exceptionally strong capability to capture infrared light with high QE values at 650nm. It features a large full well capacity, high dynamic range, high sensitivity, and low readout noise among other advantages. Equipped with HCG/LCG dual gain mode switching, the minimum read noise can reach 0.4e⁻, making it one of the lowest read noise monochrome guide cameras currently available. This results in outstanding performance in planetary photography, as well as in solar and lunar photography.
