Meet G3M664C
Large Sensor Format & High-Resolution Color Imaging
Powered by Sony’s advanced STARVIS 2 IMX664 color sensor, the G3M664C combines a large 1/1.8" format (4.08MP) with an impressive 38 ke⁻ full well capacity and ultra-high Quantum Efficiency (>91%). Designed for expanded field-of-view solar and lunar mosaics as well as fine planetary detail, it captures rich, true-to-life colors while delivering excellent dynamic range without amp glow.
G3M664C Planetary Camera Performance Analysis
Mono VS Color
Which Do You Need For Planetary Imaging?
One-Shot Color (OSC) Planetary Cameras
Equipped with an RGB Bayer filter array, One-Shot Color planetary cameras capture true-color planetary videos in a single sequence without requiring filter wheels or costly filter sets. While highly efficient for fast-rotating planets like Jupiter, Bayer interpolation causes physical resolution and sensitivity losses, as pixels are split between red, green, and blue light collection.
Monochrome Planetary Cameras
Monochrome planetary cameras capture raw light across 100% of the pixel array with no Bayer filter losses, delivering maximum spatial resolution, superior SNR, and razor-sharp surface details. Although producing true-color LRGB images requires capturing sequential RGB streams using a filter wheel, the sensor's extreme sensitivity enables shorter exposure times to freeze atmospheric turbulence. It also unlocks specialized imaging using CH4 (Methane), UV, and IR-Pass filters for advanced planetary, lunar, and solar details.
Unlocking Planetary Details
NIR Imaging & Atmospheric Penetration
Saturn by TritonYung
Paired with an 850nm IR-Pass or 890nm Methane (CH4) filter, the G3M678M isolates deep atmospheric structures on Jupiter and Saturn, revealing subtle cloud dynamics invisible in standard light.
Why Choose G3M Series Planetary Camera
512MB DDR3 High-Speed Buffer & Sony STARVIS 2 Technology
Built on Sony’s next-generation STARVIS 2 back-illuminated technology, the sensor features reduced dark current, lower readout noise, and higher dynamic range. Coupled with an onboard 512MB DDR3 high-speed RAM buffer, the G3M series guarantees smooth, frame-drop-free data transfer while preventing sensor heating and buffer-induced artifacts during long recording sequences.
Zero Amp-Glow
The G3M series features advanced circuit architecture that completely eliminates amp-glow at the hardware level. Whether shooting high-frame-rate planetary videos at high gain or longer exposures for autoguiding, your raw frames remain clean, pristine, and artifact-free.
2-in-1 Versatility: Planetary & Guiding
Why buy two cameras when one can do it all? G3M series serves as high-end planetary cameras while doubling as ultra-sensitive auto-guiding cameras for deep-sky astrophotography setups.
Compatible with OAG and Guide Scope
Featuring a standard 1.25" form factor, the G3M series planetary camera seamlessly fits into standard 1.25" focusers, guide scopes, and Off-Axis Guiders (OAGs) from ToupTek Astro and third-party brands, making it an effortless upgrade for any astrophotography imaging train.
Standard & Extended Versions
The Standard Version uses a C-mount for standard accessories and telescopes. The Extended Version uses a CS-mount with a longer front barrel and shorter flange focal distance for broader OAG compatibility. Both versions accept 1.25-inch filters when connected through a 1.25-inch extender.

Frequently Asked Questions
What is the difference between the G3M series and GPM series cameras?
G3M is ToupTek Astro's planetary camera series, designed primarily for high-frame-rate planetary, lunar, and solar imaging. GPM is the guide camera series, designed primarily for autoguiding. Both series can also support selected near-infrared imaging workflows, so choose G3M when high frame rate is the priority and GPM when guiding is the primary task.
What accessories are needed for infrared Milky Way imaging with G3M/GPM cameras?
For infrared Milky Way imaging, prepare an IR-sensitive G3M or GPM camera, a compatible lens, an infrared-pass filter, a stable tripod or support, a laptop, smartphone, or compatible controller for image acquisition, and the required USB data cable. For a G3M camera, remove the front C-mount or CS-mount ring, then install the LP825 filter CS-adapter ring together with the lens.
What is the difference between the Standard Version and Extended Version?
The Standard Version uses a C-mount for standard accessories and telescopes. The Extended Version uses a CS-mount with a longer front barrel and shorter flange focal distance for broader OAG compatibility. Both versions accept 1.25-inch filters when connected through a 1.25-inch extender.
