The Altair GPCAM3 664C Colour camera has both very high sensitivity in the green wavelengths crucial for planetary imaging and the near IR red regions.

With a full well depth of 39 ke- the camera has very high dynamic range compared to most planetary cameras, meaning higher gain settings can be used to maintain high frame rates - even on dim targets like Saturn.

The sensor has no amp glow and therefore offers better performance for deep-sky imaging or video astronomy. Read noise of 5.35 – 0.46 e- depending on gain setting, is also extremely low.

increased full well capacity, high dynamic range, high sensitivity, and low readout noise are characteristic of the latest STARVIS 2  CMOS technology.

Feature summary Altair 664C CMOS Camera:

• IMX664C Colour CMOS Sensor
• On-chip HGC, LCG and HDR Support
• Resolution: 2688 x 1520 (4.1mp)
• 2.9 um Square Pixels
• Diagonal 9.02 mm (Type 1/1.8 Optical Format)
• 12-bit ADC
• 512 Mbyte Memory
• Sensitivity: 2000 m V or more per 1 µm2
• Low Noise: 6.2 – 0.69 e-
• High Frame Rate 97 FPS @ 2688*1520 8bit mode
• 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 www.altairastro.help. 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.

Furthermore, the popular PHD Guiding, SharpCap PRO, APT and NINA are also natively supported. ASCOM drivers are also available for download at www.altairastro.help 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 this 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, 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. Common astronomy file format information here.
