Capture stunning celestial images with the Altair GPCAM2 224C Color CMOS Camera with USB2. This high-performance camera is perfect for astrophotography enthusiasts. Featuring a 1/3" Sony IMX224 color CMOS sensor, it delivers exceptional image quality and color reproduction. With its USB2 interface, it offers fast and reliable data transfer to your computer. Whether you're a beginner or an experienced astronomer, the Altair GPCAM2 224C is a versatile and reliable tool that will take your astrophotography to new heights.

The Altair GPCAM2 IMX224 Colour camera has the sought after Sony Exmor IMX224 CMOS sensor, with high sensitivity, and extremely low read noise.
 
It can be used for solar, planetary, lunar lucky imaging, deepsky imaging and of course video astronomy or EAA. Time-lapse all-sky imaging (with optional meteor lens) is fully supported. You would be hard-pressed to find a more versatile small-format colour astronomy imaging camera with this price and features.

Faster than the GPCAMv1. Onboard buffering gives USB data transfer speeds significantly higher than the GPCAM1 series, pushing the USB2.0 format to the limit, yet within a stable envelope. This almost completely eliminates dropped frames, corrupted video, and enables faster more consistent frame rates, even with less powerful notebook computers.
 
AutoGuiding: The camera has an ST4 auto-guiding port, and can be used to auto-guide with mounts from all the major manufacturers supporting ST4 format, such as iOptron, Celestron and Skywatcher. (lead included)
 
And what's more, you get UK/EU based warranty support, plus the Altair Camera Google User Group for all your technical questions - a great place to share tips and techniques to get the best out of your camera.
 
Cool casing design: The casing has an external heatsink surface, which dissipates heat generated by the electronics, reducing thermal noise. 
 
Reliable USB connector: The USB2.0 connector is the high strength type - the highest quality component of it's type on the market. This is much more reliable than the micro-USB connectors found on smartphones (we all know how those loosen up over a short time!). (USB 2.0 lead included)
 
Multi-Format: The camera can be fully controlled in AltairCapture and SharpCap to output uncompressed .AVI and .SER video files for solar system imaging, as well as all common still image formats such as .JPEG .PNG .TIF .BMP, to mention just a few. The GPCAM supports 8bit or 12bit output. The 12 bit output mode can be used for deep sky imaging with less frames needing to be stacked and a wider pixel intensity range. The IMX224 sensor is extremely sensitive in the IR region (for all pixels not just red!) and can be used effectively with IR Pass filters for solar and lunar imaging in mono mode.
 
Whats different about the GPCAM2 platform compared to the GPCAM1 platform? Youll notice the GPCAM2 casing is larger than the GPCAM. This is to house larger electronics boards which support trigger mode and frame buffering as well as to increase the surface area for cooling. The GPCAM2 platform supports Trigger Mode to make long exposures of over 5 seconds easier to control.

With most cameras, in normal video mode, you have to wait for an exposure to complete before the camera will accept, say a command to abort the frame, for say clouds, aircraft, or an alignment issue, like kicking the tripod and so-on, or for routine changes in gain, exposure time, , re-aligning or refocusing on the object.

For long exposures, normal video mode is inconvenient, especially for video astronomy and deep-sky imaging, however in Trigger mode, you can stop the camera instantly (even if you are half way through a long 30 second exposure) change the settings, and re-start the camera looping again. The GPCAM2 also has an improved onboard frame buffer to improve data transfer stability at high frame rates (to reduce dropped frames) and to increase compatibility with a wider range of PCs.

The improved buffers give a more consistent data transfer rate over USB2.0 and USB3.0 buses on laptops and desktop PCs.
