Unlock Stunning Astrophotography with the Sony IMX249 Monochrome CMOS Sensor

GPM174M Mini Guide Camera
GPM174M guide camera features Sony IMX249 CMOS mono sensor (1/1.2” size, 11.3mm 7.03mm), offering a high resolution of 1920 x 1200 pixels. With a pixel size of 5.86 μm x 5.86 μm, this guide camera excels at capturing faint signals (with a high QE value at 500nm), ensuring detailed and precise astrophotography for both beginners and professional astrophotographers.
Key Features: Larger FOV (Field-of-view)
High Full Well Capacity
High Sensitivity
Low Readout Noise
Built-in Frame Buffer
Easy Connection to 1.25” Telescope, 1.25” Extender and OAG-X Ideal for Planetary, Solar, and Lunar Astrophotography.

Camera Sensor
GPM174M offers low read noise, high dynamic range, and AR-coated glass—perfect for planetary imaging and guiding in astrophotography.

Astrophotography Performance
GPM174M High Sensitivity: the QE peak value is about 89%.

e/ADU, Read Noise Full Well and Dynamic Range for GPM174M
Read noise is the most important reference to measure the performance of a camera. Lower read noise usually means better SNR and better quality of image.

Built-in Frame Buffer
GPM174M guide camera comes with a built-in frame buffer that stabilizes data transmission and significantly reduces amp-glow. By temporarily storing image data, it prevents rushed transmission to the receiver, ensuring consistent performance even when multiple cameras are in use. This feature maintains the camera’s high frame rate for optimal imaging during complex astrophotography sessions.
