![]() 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 re-focusing on the object. The GPCAM2 platform supports “Trigger Mode” to make long exposures of over 5 seconds easier to control. This is to house larger electronics boards which support trigger mode and frame buffering as well as to increase the surface area for cooling. You’ll notice the GPCAM2 casing is larger than the GPCAM. What’s different about the GPCAM2 platform compared to the GPCAM1? 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. FITS file is stretched to 16bit for post processing compatibility). The sensor sensor is extremely sensitive and a good candidate for video astronomy, especially with small refractors (the final. 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 supports 8bit or 12bit ADC output. FITS (for deepsky imaging) to mention just a few. SER video files for solar system imaging, as well as all common still image formats such as. The camera can be fully controlled in AltairCapture and SharpCap to output uncompressed. This is much more reliable than the micro-USB connectors found on smartphones (we all know how those loosen up over a short time!). The USB2.0 connector is the high strength type – the highest quality component of it’s type on the market. The casing has an external heatsink surface, which dissipates heat generated by the electronics, reducing thermal noise. The sensor is more than sensitive enough for 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, including iOptron, Celestron and Skywatcher. The installation process is easy, and unlike with cheaper cameras, you don’t need to be a computer expert to make your camera work. ASCOM drivers are also available for download at you can also get regular driver updates. Furthermore, the popular PHD Guiding, SharpCap are also natively supported. It includes extensive automation features, and supports all the major file formats useful for astro imaging and professional scientific imaging in 8bit or 12bit (output scaled to 16 bit for processing). Unlike cheaper cameras, Altair Astro has spent considerable time developing the extensively featured and intuitive AltairCapture software, which can be downloaded from AltairCapture is a stable 64 bit Windows application, which allows full control of the camera in high speed video or still mode. This almost completely eliminates dropped frames, corrupted video, and enables faster more consistent frame rates, even with less powerful notebook computers. 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.
