ToupTek GPM462C - Ultra-sensitive planetary camera & color autoguider (IMX462)

Visit ToupTek GPM462C is a camera planetary/guidance color 1.25″ format, built around the backlit sensor Sony IMX462 (1/2.8″).
Its very high sensitivity, particularly in the near infrared range, and its ultra-low read noisehis 12-bit ADC and its internal buffer make them an excellent choice for the Moon, planets and Sun (with appropriate filters), as well as for theself-steering via port ST-4 integrated.

Highlights

Sensor : Sony IMX462 colorBSI, 1/2.8″ format (diag. 6.39 mm).
Resolution : 1920×1080 (≈ 2.1 MP) - pixels 2.9 µm square.
12-bit ADC - Hardware ROI - digital binning 1×1 to 8×8.
Playback noise very low: typ. 0,76 → 2,4 e- depending on gain.
Pleine-puits to ~12.7 ke- - SNR max to ~48 dB - dynamics ≈ 74.1 dB.
Speed up to ~17.8 fps 8-bit (full sensor) - ~8.9 fps in 12 bits.
Integrated ST-4 for self-steering - USB 2.0 Type-C with frame buffer for stable transmission.
Window IR-cut (380-690 nm) or AR depending on version.
1.25″ mounting (M28.5×0.6) + adapters C/CS provided.
