The Altair Hypercam 183C is a 20mp astronomy camera, featuring amp glow reduction, and low read noise, producing extremely smooth, detailed images. The Sony IMX183 sensor is one of the most sensitive backside illuminated (BSI) sensors available at the moment with such a high megapixel rating, and it has incredibly low read noise.
The new Version 2 camera for release mid November has the following new features:
Temperature sensor, with data available in realtime.
ROI (Region of Interest) for cropped higher speed solar, lunar and planetary imaging.
4K Mode (cropped).
SPECIAL OFFER! FREE 1 YEAR SharpCap PRO License! Includes ultra-accurate polar alignment assist, deepsky CMOS exposure time optimisation assist, live stacking for EAA/Video astronomy, live darkframe and flat frame subtration.
Easier than a DSLR and no "astro modding" required: Hypercam is much easier to use and focus than a DSLR, thanks to the live preview mode in AltairCapture and SharpCap software. You can see a tiny star clearly in real-time, because there is no video compression. Unlike a DSLR, there's no need to modify your camera to capture detail in red hydrogen wavelengths, because it has no red blocking filter in the way. There are no clumsy power connectors, no mirror to lock up, and a "true" RAW mode output. You get what this Sony sensor sees.
Low read noise. The Sony IMX183 CMOS sensor has very low read noise, wide dynamic range, and high sensitivity. The IMX183 ExmorR rated Back Illuminated Sensor has high-sensitivty, low dark current, no smear, and excellent anti-blooming charateristics. BSI technology moves the sensor circuitry behind the pixel, so unlike conventional sensors the light path is not blocked, resulting in higher quantum efficiency than a CCD sensor.
Try deep-sky "lucky" imaging. Short exposures stacked take advantage of high resolution sensors with low read noise, reducing atmospheric aberrations and tracking errors or wind vibration. The more frames you stack, the smoother the image becomes, and the higher the dymanic range. Long cumulative exposure times of many hours can be achieved with modest equipment. The result is a smoother, sharper image, while suppressing any residual amp glow.
Great for refractors. With a pixel size of 2.4um, and a sensor size of 13.0 x 9.00 mm, the Hypercam IMX183C is best suited for imaging at F7 or faster speeds, and performs extremely well an Altair refractor, and say an 0.8sx focal reducer.
Video Astronomy/EAA Friendly. The Hypercam IMX183 sensor is not only desirable for Deepsky Imaging - it's also great for Video Astronomy or "EAA" Electronically Assisted Astronomy. All thanks to the 20mp resolution, high sensitivity, and amp glow reduction technology. What's more you can use the Live Stacking features in the AltairCapture software or SharpCap PRO. Time-lapse all-sky imaging or video is easy with a DSLR lens and optional Hypercam Lens Adapters (product code: CLA-EOS or CLA-NIKON).
To sum it up, the most desirable features of the Hypercam IMX183 camera are:
- 1" diagonal (15.86mm) SONY Exmor R Back Side Illuminated IMX183 Color CMOS sensor
- 20mp resolution with 5440 x 3648 active pixels in a 13.00 mm x 9.00 mm array
- Extremely low read noise enabling deepsky lucky imaging and very smooth image quality.
- Amp glow reduction technology onboard reduces amp glow, reduces noise, and increases contrast.
- High Dynamic Range with 12 bit ADC to 16bit output .FITS files in RAW mode, for beautiful deepsky images.
- Up to 17.5 Frames per second video in full 20mp 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).
More technical stuff:
Pure RAW mode and "digital" RGB output modes for better post processing: The Hypercam sensor ADC can 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 digitial" 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 and on-board memory buffering give much faster transfer speeds than USB2.0 cameras, however, if like most imagers, you prefer to use longer and more flexible USB2.0 cables for better tracking and reliability with a USB2.0 hub, no problem! The Hypercam is completely compatible with USB2.0 protocol. Just install the software, and off you go!
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 cameras.altairastro.com. 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. Furthermore, the popular PHD Guiding, SharpCap and Firecapture are also natively supported. ASCOM drivers are also available for download at cameras.altairastro.com where you can also get regular driver updates. The installation process is very simple, and unlike with cheaper cameras, there is no need to waste time tweaking .DLL files to make your camera perform as expected.
SharpCap PRO: Altair Astro have worked closely with SharpCap developer Robin Glover 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.
Wide operating system and USB compatibility: Although the Hypercam is a USB3.0 camera, it is also fully compatible with USB2.0 ports when a longer cable and less speed are required, for example in deepsky or video astronomy using the live stacking features in AltairCapture or Sharpcap. Windows 7 to Windows 10 software is widely supported by AltairCapture in 64bit mode (see technical info for details).
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 IMX183 is more than sensitive enough for autoguiding.
Fan cooling: The Hypercam is cooled with and internal low vibration fan. The fan can be switched on or off and the speed controlled in AltairCapture and SharpCap. Cool air is drawn in through the vents at the side of the casing, over a large internal heat-sink. The heat-sink is connected directly with the sensor board just like a computer CPU. The free flow of air through the casing cools not only the sensor, but all the internal electronics boards. Cooling is especially desirable for long exposure imaging to reduce thermal noise. Some camera casings get uncomfortably hot during a solar imaging session, and the sensor can reach around 60 or even 70 degrees. This can cause the electronics to become glitchy and unreliable. The Hypercam is designed for consistent, reliable solar imaging with a solar filter and diagonal or Altair Solar Wedge. With the fan running, the Hypercam casing will always remain cool.
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 Altair Camera Google User Group where you can get answers to technical questions. The group is also a great place to share tips and techniques, to get the best out of your camera. 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 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.
