The 21mp Sony IMX269 is a 12bit colour 4/3rds sensor with 3.30 m Pixels - a better, more sensitive replacement for the now discontinued colour Panasonic MN34230 Series used on the 1600 series - but with similar image scale and pixel size.

The Hypercam's amp glow reduction is very efficient and at normal gain levels, no amp glow is visible at all. This makes it much easier to process - especially for beginners. Due to it's low read noise, the Hypercam 269C PRO camera is suitable for both deepsky and "lucky" solar system imaging with ROI. 

The Hypercam 269C PRO Fan Cooled camera has the following features:

  • Easiest true astro-camera for beginners to use and process images!
  • No amp glow. We cannot detect any amp glow with this camera in normal use.
  • Fan cooling to give you the edge vs. passively cooled cameras.
  • Temperature sensor, with data available in real time, temperature written to .FITS files for easier processing.
  • ROI (Region of Interest) for cropped higher speed solar, lunar and planetary imaging.
  • Binning supported.

Easier than a DSLR and no "astro modding" required: Unlike a DSLR, there's no need to risk modifying your camera to capture detail in red hydrogen wavelengths, because the optical window has high red transmission. Hypercam is much easier to use and focus than a DSLR, thanks to the live preview mode which shows uncompressed video at full resolution. You can see a tiny star-point clearly in real-time, making focusing easier, because there is no video compression like with a DSLR video stream. This camera is so much easier to use than a DSLR for astro imaging. Only one cable - the USB cable - supplies power and data. There are no clumsy power connectors which drop out easily, no "dummy batteries" required, no fiddly firmware to fight with, no mirror to lock up, and a "true" uncompressed RAW mode output. You get exactly what this Sony sensor "sees" from without alterations. That's ideal for deepsky imaging. We do recommend a laptop or PC with USB3.0 connection if possible as they tend to provide more stable, and cleaner power to the camera.

Low read noise: The Sony IMX269 CMOS sensor has very low read noise at approx. 2.6e and the usual high-sensitivity, low dark current, no smear, and excellent anti-blooming characteristics you would expect from a CMOS sensor. Unity gain is 282 in High Conversion Gain mode and 565 in Low Conversion Gain mode SharpCap and most other imaging applications (2.82 / 5.65 in AltairCapture).

Video Astronomy/EAA Friendly. The Hypercam 296C camera is not only desirable for Deepsky Imaging - it's also great for Video Astronomy or "EAA" Electronically Assisted Astronomy. The resolution, high sensitivity, and amp glow reduction technology are well suited to this task. What's more, you can use the Live Stacking features in the AltairCapture software or SharpCap PRO. All-sky time-lapse imaging or video is easy with a DSLR lens and optional Hypercam Lens Adaptors (product codes starting with: CLA-EOS or CLA-NIKON).

To sum it up, the headline features of the Hypercam 269C camera are:

  • 21mp resolution SONY Exmor IMX269 CMOS sensor.
  • 5280x3956 active 3.3 micron pixels in a 20.49 mm × 17.83 mm array. Physical sensor size, 4/3rds" 21.77mm diagonal.
  • Extremely low read noise enabling deepsky lucky imaging and very smooth image quality.
  • Amp glow reduction technology onboard eliminates amp glow, reduces noise, and increases contrast.
  • A 12 bit ADC converting to 16bit output .FITS files in RAW mode, for deepsky imaging.
  • Up to 17.5 Frames per second video in full 21mp resolution. (You will need a computer with high USB bandwidth to achieve these speeds, preferably with Intel or Via hardware USB controller on the motherboard).

Pure RAW video and stills mode and "digital" RGB output modes for better post processing: The Hypercam sensor ADC can deliver 12bit RAW files, which are stretched to 16 bit. In RAW mode analog (on-sensor) gain is used for ultra low read-noise images. Because the output is completely "RAW" in analog mode, there is no partial "downstream digital" processing like with a DSLR or other cheaper Chinese cameras of similar design, resulting in true RAW mode for the best deepsky performance. True RAW mode allows greater flexibility and consistency in processing large stacks of frames for deepsky "lucky" imaging, where the camera's low read noise can be taken advantage of. Either .FITS image or .SER video files are captured in their purest form for later processing in your software of choice. Of course for Video Astronomy / EAA use, you can select RGB Mode and capture .AVI files, or just view the screen with full access to white balance, gamma, contrast and histogram controls, just like any other camera.

USB3.0 speed and USB2.0 reliability:
USB3.0 gives much faster transfer speeds and generally better results and is more reliable than USB2.0 connections with these cameras. However the Hypercam is compatible with USB2.0 as well. Generally desktop PC's have better USB2.0 than laptops.

QUALITY software and drivers included:
AltairCapture: Unlike cheaper cameras, Altair Astro has spent considerable time improving 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. It includes extensive automation features, and supports all the major file formats useful for astro imaging and professional scientific imaging in 16bit, 12bit or 8bit mode. The popular PHD Guiding, SharpCap PRO, and Deepsky imaging software APT and NINA are also fully supported. An ASCOM driver is available for other software, downloaded at where you can also get ASCOM driver updates. The installation process is simple and straightforward, starting with AltairCapture which contains the driver base.

SharpCap PRO free license: Altair Astro have worked closely with SharpCap developer since 2015, to fully integrate Altair cameras with SharpCap at a basic level. Now, Sharpcap PRO enables even more features with this camera, such as software driven polar alignment (more accurate than any other method), live flat frame subtraction and live darkframe subtraction. The fast, accurate polar alignment feature in SharpCap PRO is a life-saver for imaging, minimising setup time. 
Fan cooling:
The Hypercam has an internal heatsink with fan cooling system connected directly to the sensor. Cooling is helps reduce thermal noise which accumulates during long exposures and the fan cooling reduces temperature-build-up for better calibration with darkframes. The result is a nice smooth image, easier processing, and less sub-frames required.
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 visit the Altair Astro Facebook Group where you can get answers to technical questions and share tips and techniques, to get the best out of your camera. The AltairCapture software interface supports most European languages including English, German, French, Japanese, Korean, Polish and Spanish.
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 Hypercam 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 sensor is extremely sensitive and a good candidate for video astronomy, especially with small refractors. Find out more about bit depth here. Find out more about video & file formats here.
The Hypercam platform: The Hypercam 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, changes in gain, exposure time, or re-aligning or refocusing. 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 exposure) change the settings, and re-start the camera.
