ASI 294 MM Mono Camera

The ASI 294MM is the first uncooled CMOS camera with the new Sony IMX492 sensor. It is an ideal camera for photographing the sun, moon, and planets, as well as for DeepSky shots. The model uses Sony's modern "Back Illumination" technology.
The ASI 294's 4.6 µm pixels make this camera an all-rounder with maximum sensitivity for short exposure times.
You can even increase the resolution by using the camera in "unlocked mode". This gives you 2.3 µm pixels.

Thanks to extremely short exposure times, you can trick atmospheric turbulence (seeing) in photos of the Moon or planets with the high sensitivity available. The sensor's high resolution allows you to capture many details even with a shorter telescope focal length.
For deep-sky photography, the high sensitivity allows you to capture nebulae and galaxies in just a few seconds. Although the camera is uncooled, you can still get low-noise, high-resolution photos. By increasing the GAIN (comparable to the ISO setting on DSLR cameras), you can reduce exposure times to less than 30 seconds. This eliminates the effects of atmospheric turbulence or tracking inaccuracies.

The ASI 294MM is equipped with USB 3.0 for fast downloading but can also operate with USB 2.0. The sensitive CMOS sensor has a 23 mm diagonal, and the resolution can be "regulated" using 4.6 µm or 2.3 µm pixels.
The camera comes with a clear AR glass filter, which allows full passage even in the infrared spectrum. If IR blocking is desired, an additional IR blocking filter is needed.HCG Mode

If the gain (pre-amplification) is set above 120, the read noise is reduced below 2e. Despite the extremely high sensitivity, low-noise images are obtained.

Full Well Capacity

In "locked 63700e mode", even the brightest stars are not burned out, which provides a better signal-to-noise ratio.

Advantages:

• Sensor diagonal 23 mm
• 14-bit ADC for high dynamics
• Extremely short exposure times allow for high-resolution images
• Available connections: T2, 1.25" and 2"
