1 Description and Features GPM174M camera possesses an exceptionally strong capability to capture faint signal (with a high QE value at 500nm). It also has a large sensor format, high full well capacity, high sensitivity, and low readout noise among other advantages. This results in outstanding performance in planetary photography, as well as in solar and lunar photography.
2.2 Sony IMX 249 Sensitivity The sensor G Sensitivity of GPM174M is 825mv with 1/30s. Its spectral sensitivity is shown in Figure 1. The sensitivity is measured with a excitation LED light source with a color temperature of 3200 K, an IR cut filter CM500(t =1.0 mm) is placed between the LED light source and the sensor receiving surface to irradiate substantially parallel light.
2.5 Binning GPM174M supports software to digital binning from 11 to 88 in either stacking or averaging method. 2.6 Power and Cooling System for Precise Temperature Regulation The camera operates via a USB 2.0 interface.
