G3CMOS M42+1.25" Mount USB3.0 Guiding Astronomy Camera

Key Benefits

• USB3.0 interface enables fast data transfer and low latency for real-time guiding
• CNC aluminum alloy housing provides durability and thermal stability during long exposures
• Sensitivity from 400mv to 2650LSB allows reliable signal capture under low-light conditions
• Supports binning modes (1x1, 2x2, 3x3, 9x9) to increase frame rate or reduce noise
• Exposure times from 0.06ms to 3600s accommodate both fast guiding and deep-sky imaging
• Multiple sensor options from 2.3M to 21M pixels allow selection based on telescope focal length and field of view
• Native SDKs for Windows, Linux, macOS, and Android support integration into custom automation scripts

Application Scenarios

• Guiding a telescope during long-exposure astrophotography using a 1.25" or M42 adapter
• Tracking celestial objects with real-time feedback from a high-sensitivity CMOS sensor
• Automated imaging sequences in a remote observatory with software control via SDK
• Field use in mobile astronomy setups where compact size and robust housing are essential
• Integration into a custom guiding system using Python, C++, or C# scripts

Who It Is For

• Amateur astronomers doing deep-sky imaging with small to medium telescopes
• Professional observatories requiring reliable guiding cameras with low noise
• Educational institutions teaching astrophotography and observational astronomy
• DIY telescope automation builders using custom software and SDKs
• Remote observatory operators needing stable, low-latency guiding performance

Problems It Solves

• A standard webcam lacks the sensitivity and exposure control needed for accurate guiding
• Fixed-frame-rate cameras cannot adapt to fast or slow guiding requirements across different scopes
• Non-compact cameras with plastic housings may warp under thermal stress during long exposures
• Lack of SDK support limits integration into automated imaging pipelines
• Incompatible sensor formats or interfaces prevent direct mounting on M42 or 1.25" ports

Technical Features

• CMOS sensor with SONY Exmor, Exmor R, or Exmor RS image pickup technology
• USB3.0 interface for high-speed data transfer and power delivery
• Integrated CNC aluminum alloy housing for mechanical stability and heat dissipation
• Supports multiple binning modes (1x1, 2x2, 3x3, 9x9) to adjust frame rate and noise
• Exposure time range from 0.06ms to 3600s for flexible use in guiding and imaging
• Dark signal as low as 0.1mv (1/30s) for minimal noise in long exposures
• Frame rate up to 120 fps at 1920x1200 resolution for fast guiding
• Supports 1.25" and M42 threaded adapters for direct mounting on guide scopes
• Multiple sensor sizes from 1/1.9" to 4/3" to match different telescope focal ratios

Comparison With Other Options

Use Guide

• Mount the camera using the M42 or 1.25" adapter to your guide scope before connecting to the computer
• Use the ToupSky software or SDK to verify connection and adjust exposure and gain settings
• Set exposure time between 0.1ms and 1000s depending on guiding speed and star brightness
• Enable binning (2x2 or 3x3) to increase frame rate if tracking is unstable
• Calibrate the guiding software using the camera's high sensitivity and low noise performance
• Ensure the USB3.0 port is connected directly to the motherboard for best performance
