Altair Hypercam 183C PRO 20mp Colour Astronomy Imaging Camera Fan-cooled 4GB DDR3 RAM

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 which shows uncompressed video at full resolution. You can see a tiny star-point clearly in real-time, because there is no video compression like with a DSLR video stream. 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 which drop out easily, no firmware to fight with your software, no mirror to lock up, and a "true" uncompressed RAW mode output. You get exactly what this Sony sensor "sees" from without alterations.

4GB DDR3 RAM: The Hypercam PRO series also has an unprecedented 4GB 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 allowing longer imaging sequences with small notebooks, stick PCs, or mini-PCs. 

Low read noise BSI sensor. The Sony IMX183 CMOS sensor is ExmorR rated, and Back Illuminated (BSI). 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 traditional CCD sensor. Read noise is low, and there is no smear or “blooming” on bright stars.

Try deep-sky "lucky" imaging. The low read noise let’s you stack shorter exposures to take advantage of the 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 cumulative dynamic range. In this way, long cumulative exposure times of many hours can be achieved with modest equipment. The result is a smoother, sharper image with more detail.

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. All-sky time-lapse imaging or video is easy with a DSLR lens and optional Hypercam Lens Adapters (product code: CLA-EOS or CLA-NIKON).
