Product information

The Altair GPCAM3 462M Mono camera has the highest NIR sensitivity of any planetary camera in the range, as well as extremely high sensitivity at 500nm green wavelengths.

This makes it an extremely capable planetary imaging, guiding or deep-sky video astronomy camera. In particular, the high red sensitivity benefits both Hydrogen Alpha solar and deep-sky imaging, reducing exposure duration. This camera opens up new opportunities for imaging the giants, which display high contrast in the far red wavelengths, with strong absorption lines in the Methane Bands. For auto-guiding, the camera has unparalleled sensitivity, especially for guiding in the far red region, which is useful to the combat atmospheric seeing effects that affect guiding.

The full well capacity, high dynamic range, high sensitivity, and low readout noise are characteristic of the latest Starvis BSI CMOS sensor technology.

Feature summary Altair 462M:

  • 1920 x 1080 Resolution 
  • 2.9 um Square Pixels
  • 1/2.8-inch sensor format
  • 5.57mm x 3.13mm sensor size
  • Low Read Noise: 0.49 to 2.1e- 
  • High Frame Rate 152 FPS 8 bit
  • 12-bit ADC
  • Binning from 1x1 to 8x8 in either stacking or averaging modes.

Speed and reliability: USB3.0 format is fast yet stable, and a 512mb DDR3 Memory buffer enables faster more consistent frame rates.
Included software: The well featured intuitive AltairCapture software is included in a CD ROM, and can also 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. It includes extensive automation features, and supports all the major file formats useful for astro imaging and professional scientific imaging in 14bit or 8bit mode.

SPECIAL OFFER! FREE 1 YEAR SharpCap PRO License included with all Altair GPCAM3 Cameras!

Furthermore, the popular PHD Guiding, SharpCap PRO , APT and NINA are also natively supported. ASCOM drivers are also available for download at where you can also get regular updates. The installation process is easy, and unlike with cheaper cameras, you don't need to be a computer expert to make your camera work. Just install the software on the CDROM, plug in the camera, and that's it.

Wide USB compatibility: Although the GPCAM3 is a USB3.0 camera, it's also fully compatible with USB2.0 ports when a longer cable and less speed are required, for example in deep-sky or video astronomy using the live stacking features in AltairCapture or Sharpcap.
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 sensor is more than sensitive enough for autoguiding. 
Support & warranty: Altair delivers proper on-shore English-speaking UK & EU support with a 2 year manufacturer warranty against defects in materials and workmanship. New users should check out the Altair Astro Facebook Group where you can get answers to technical questions, as well as sharing tips and techniques. 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.
