Designed for deep-sky autoguiding and infrared imaging, the GPM585M features a Sony IMX585 back-illuminated monochrome CMOS sensor with a 1/1.2" optical format, 2.9 µm pixels, and 3840 x 2160 resolution. Offering excellent sensitivity, dynamic range, high full-well capacity, and low read noise, this camera delivers outstanding infrared response, making it ideal for capturing the Milky Way in infrared wavelengths, even under heavily light-polluted city skies.
Equipped with an RGB Bayer filter array, one-shot color guide cameras capture color star images without additional filters. They are convenient for quick setup and checking star color. However, the Bayer array reduces the light reaching individual pixels, and color interpolation can slightly reduce effective detail. As a result, OSC cameras can be less effective at detecting faint guide stars, particularly under light-polluted skies.
Monochrome guide cameras do not use an RGB Bayer filter array, so they avoid the associated color-filter light losses. This generally improves sensitivity and signal-to-noise ratio, helping the camera detect faint guide stars that color cameras may miss. No filter wheel is required for autoguiding. Mono cameras are often preferred for deep-sky astrophotography setups, especially under light-polluted skies.
Featuring the high-performance Sony IMX585M monochrome CMOS sensor, the GPM585M delivers stunning 4K Ultra-HD imaging with a 3840 x 2160 resolution. Its large 1/1.2" sensor format and 12.85 mm diagonal provide a wide field of view, while the 2.9 µm pixels balance fine detail, sensitivity, and low-noise performance. This combination makes it ideal for capturing sharp planetary details and intricate deep-sky structures with exceptional clarity.
The GPM585M features an AR-coated protective window measuring 19mm in diameter and 0.55mm thick, secured within the adapter by a retaining ring. For expanded infrared imaging capabilities, the window can be easily removed and replaced with a compatible third-party filter measuring 19-22mm in diameter and approximately 1mm thick, allowing users to customize the camera for infrared imaging applications.
Powered by Sony's next-generation STARVIS 2 back-illuminated sensor technology, the GPM series delivers lower dark current, lower read noise, and higher dynamic range. Its built-in frame buffer temporarily stores image data for stable, complete transfer, helping reduce dropped frames and transmission errors during high-speed capture or multi-camera operation.
The GPM585M supports control via the StellaVita app and can be connected using the native ToupSky software. It is also compatible with ASCOM, INDI, and DirectShow SDKs. If third-party software is compatible with these SDKs, you can download the corresponding drivers from the ToupSky Astronomy official website and install them into your third-party software.
The GPM585M features a native 12-bit ADC that delivers 4,096 grayscale levels for greater tonal detail than standard 8-bit imaging. Hardware ROI enables faster frame rates when capturing smaller regions, making it ideal for high-speed autoguiding. Additionally, software-based 1x1 to 8x8 digital binning combines adjacent pixels to improve signal-to-noise ratio, enhancing faint guide-star detection and maintaining stable guiding performance.
The GPM series cameras offer versatile connection options designed for seamless integration with various telescope setups and guiding systems. Integrates easily with your OAG, finderscope, or other imaging equipment for optimal guiding performance.
