The C2-46000 also employs the 4/3 standard sensor and the imaging area is very similar to the famous G2-8300 (19.3 mm × 13.1 mm vs. 18.1 mm × 13.7 mm), only the CMOS based C2-46000 offers much greater number (46 M vs. 8 M) of much smaller pixels (2.315 μm vs. 5.4 μm). But the C2-46000 can be binned 2 × 2 to get the comparable number of similarly sized pixels (approx. 12 M). Thanks to the great download speed of the CMOS sensor and the C2-46000 ability to 2 × 2 bin pixels in camera hardware, the download speed is still much faster compared to its CCD predecessor (0.2 s vs. 5 s). The binning brings one more advantage — while the C2-46000 operates with 12-bit digitization at full resolution, the 2 × 2 binned images offer 14-bit dynamic range.

The C2-46000 shares all the features of the C2 camera series, like the efficient and regulated sensor cooling, mechanical shutter for automatic dark and bias frames, compatibility with a wide range of internal and external filter wheels, OAG adapters, Canon EOS and Nikon lens bayonet adapters etc. So, the C2-46000 easily slips into an existing imaging setup like any other C2 camera.

The image above is the first light image, taken with the C2-46000 camera prototype on 400 mm, f/4 Newtonian telescope. Even the full-size image, available on click on the image thumbnail, is actually scaled down from full resolution. So, we cropped a 1024 × 768 sub-frame from the original image and included it below to demonstrate the excellent resolution of the C2-46000's 46-megapixel sensor.

The C2-46000 is also an excellent camera for deep sky imaging. We haven't had enough time to get a full color image yet, but this white light image of NGC4565 gives an indication of its capabilities.

Images above were captured by Martin Myslivec.
