Touptek GPM174M (IMX249) 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.

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

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

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.

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.
