Altair Hypercam 174M Mono Astro Camera Fan-cooled Sony Sensor D=13.4 mm

Altair Hypercam IMX174 - USB3.0 Mono Guide/Imaging Camera

The Altair Hypercam IMX174 camera has the sought-after Sony Pregius Global Shutter IMX174 CMOS sensor, with extremely low read noise and 2.3 mp resolution.

The IMX174 sensor is particularily desirable for solar and high resolution planetary imaging at long focal lengths, where high frame rates, and high dynamic range are required to get the most detail in post processing.

Hypercam IMX174 imaging applications:

The IMX174 sensor is a very good match for the Daystar Quark and Altair Astro refractor combinations because the large pixel size, global shutter, low read noise and wide dynamic range allow prominences and surface detail to be captured in the same frame, without having to over-expose the image and lose detail. Images sharpen up very well because there is no fixed pattern noise with this sensor. The Hypercam IMX174 camera has been developed with solar imaging in mind, and works best with 100 mm plus refractors and the Daystar Quark operating at around 3000 mm focal length or more. It really comes into it´s own with larger refractors.

To sum it up, the most desirable features of the IMX174 sensor are:

Large format 1/1.2" sensor

Peak quantum efficiency of 78%

Global shutter eliminates motion distortion inherent in rolling shutter sensors, as well as CCD-smearing.

Fixed pattern noise (common with global shutter CMOS cameras) is eliminated

Low read noise 6 electrons (e-)

Saturation (full well) capacity 32,000 electrons (e-)

Dynamic range 73 dB

Video astronomy and long exposure deepsky imaging: Although the Hypercam IMX174 is considered the best tool for long focal length solar system imaging, it is also quite capable of long exposures, and will deliver very good results for deepsky imaging and video astronomy (or EAA) using the Live Stacking features in the free AltairCapture software or SharpCap. (Firecapture is also supported - now in Beta release). Time-lapse all-sky imaging and video is fully supported, and the camera can be used with a CS-Mount lens to hunt for meteors or aurora.

Speed and reliability in one camera: USB3.0 and on-board memory buffering give much faster transfer speeds than the GPCAM USB2.0 series, pushing the USB3.0 format to the limit, yet within a stable envelope. Memory buffering almost completely eliminates dropped frames and corrupted video files, a common problem with USB cameras, and enables faster more consistent frame rates, even with less powerful notebook computers. Consistency and stability is improved for video capture sequences - especially desirable for scientific applications.

QUALITY software and drivers included: Unlike cheaper cameras, Altair Astro has spent considerable time developing the extensively featured and intuitive AltairCapture software, which can be downloaded from Altair Astro Customer Support. 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. Furthermore, the popular PHD Guiding, SharpCap and Firecapture are also natively supported. ASCOM drivers are also available for download at Altair Astro Customer Support 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.

Wide 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 IMX174 is more than sensitive enough for autoguiding.

Fan cooling: The Hypercam is cooled with an 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 Celsius. 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 Hershel Wedge. With the fan running, the Hypercam casing will always remain cool.

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.

What’s different about the Hypercam platform compared to the GPCAM platform? You’ll notice the Hypercam has a larger casing than the GPCAM and GPCAM2. This is to house larger electronics boards which support trigger mode and frame buffering, the additional electronics for USb3.0 support, and to house the fan-cooled large heat-sink.

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, or for routine changes in gain, exposure time, re-aligning or refocusing on the object. 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 30 second exposure) change the settings, and re-start the camera looping again. The Hypercam also has an improved on-board frame buffer to improve data transfer stability at high frame rates (to reduce dropped frames) and to increase compatibility with a wider range of PCs. The improved buffers give a more consistent data transfer rate over USB2.0 and USB3.0 buses on laptops and desktop PCs.

Practical tip from Teleskop-Service: Storage of cameras and accessories

Especially in our latitudes, the nights are often very humid. When it cools down, however, moisture from the inside also condenses on the entrance window or sensor. Quickly a photo session is over, because the image becomes cloudy.

Good storage is an important preventive measure against dew and also prolongs the life of the camera.

After use, put the camera immediately into the TS Protect Case and add some silica gel. During storage, the silica gel will suck the moisture from the inside of the camera. At the same time, it prevents the humid room air from entering. Your camera or accessories will always be ready for you in optimal condition. You can find the silica gel and the case in our product recommendations.
