Product information

The Altair GPCAM3 287M is a specialist solar, planetary and guiding camera with an extremely fast frame rate and Global shutter. 

The frame rate can reach a maximum 540fps on a high-end laptop, earning it the nickname of Baby Shark. 

The 0.4mp sensor has 6.9µm pixels in a 720x540 pixel array to suit long focal length telescopes. 

This camera is of particular interest to planetary, lunar and solar imagers, especially for long focal length, high resolution imaging. We recommend this camera for advanced users, who are familiar with long focal length imaging with a crop factor.

Solar Imaging: The pixel size is well suited to refractors of 115mm or larger, and the Altair Solar Wedge and 2-3X Flat Field Barlow, or the DayStar Quark, as well as reflectors of larger aperture using Baader Astro Solar Film and the Altair NUV 395nm filter.

Auto Guiding: Another application is guiding with an OAG or Off Axis Guider, where the relatively large pixel size would be ideal for guiding at the full focal length of the main imaging scope. The camera has an ST4 auto-guiding port, and can be used to auto-guide directly with mounts from all the major manufacturers.

Lunar and planetary imaging: Not only is the GPCAM287M ideal for high speed Mono planetary imaging with filters, but also delivers impressive high power lunar imaging results with large reflectors. 

File formats: The camera supports 8bit or 12bit ADC output. The camera can be fully controlled in AltairCapture and SharpCap to output uncompressed .AVI and .SER video files for solar system imaging, compressed MP4 files for social media uploads, as well as all common still image formats such as .JPEG .PNG (12bit) .TIFF (12bit) .BMP, and .FITS (12bit) for deepsky imaging. 

To get an idea of what this camera is capable of, weve included lunar images with a 10 reflector and 2X Flat Field as well as a screenshot showing the capture area. 10,000 frames were acquired in approximately 19 seconds of which only 1000 were stacked in Autostakkert and Registax.
