Product information

Altair GPCAM3 715C Colour camera is a high resolution 8.3 megapixel, BSI colour camera with extremely low read noise. This next generation Sony IMX715 sensor can be used for high speed solar system imaging, or even video astronomy and deepsky imaging with a small refractor, thanks to the small pixel size. The 1/2.8-inch optical format is quite suitable for an Allsky camera lens (sold separately).

The ROI (Region of Interest) feature can be used for even higher frame rates when imaging the planets, sun or moon at high magnification.

The AltairCapture software interface supports most European languages including English, German, French, Indonesian, Japanese, Korean, Polish, Russian, Chinese, Spanish, Thai, and Turkish.
File formats: 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 .TIFF .BMP, and .FITS (for deepsky imaging) to mention just a few. The sensor sensor is extremely sensitive and a good candidate for video astronomy, especially with small refractors  (final .FITS file is stretched to 16bit for post processing compatiblility). Find out more about bit depth here. Find out more about video & file formats here.
