Astrophotography Performance

The ASI183 cameras has a very large full well capacity（15000e） for such small pixel size, 1.6e read noise @ 30DB, and 12stops dynamic range @ Gain=0. The ASI183 cameras also utilize firmware features to minimize amplifier glow for maximum performance in astrophotography.

Reliable Mechanics

ASI183 Pro has same mechanics as ASI1600 Pro. There are four screws that seal the sensor chamber. Our camera design has been extensively tested and is very stable.

Even when used in higher humidity environments, ASI183 Pro will still work fine without dew problems.

High Speed

Fast FPS can be used in solar(white light) and lunar imaging, as well as for live viewing/EAA.The high speed readout may also be used for real-time focusing, true lucky imaging of double stars and other small objects, planetary imaging of the major planets in the solar system, and much more.

High QE

Sony’s back-illuminated Exmor R technology, giving it excellent Deep Sky performance. ASI183 QE peak reaches a remarkable 84%. In Ha channel, QE is still over 60%.

Having high QE means more of the light that enters your telescope and reaches the sensor is actually used. With 84% peak Q.E. and no less than ~50% within the visible spectrum, the ASI183 will utilize a high percentage of the light that reaches it, improving your signal quality.

Dark Current

The dark current of the ASI183 is extremely low, based on our test results.

Dark frame sample @ Highest dynamic range settings(gain=0), 300s, -10°C, bin1. Please check the dark frame to make sure you are fully know the performance.

USB 3.0 Port & USB2.0 HUB

USB 3.0 Port: Provide 5Gb bandwidth to make it possible for ASI183 Pro to run at 19 fps (12bit, normal mode) or 19 fps (10bit, high speed mode)  at full resolution(20.18Mega).

USB 2.0 HUB: can connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can better manage your cables. The ASI183 Pro includes two short 0.5m USB 2.0 cables. The integrated USB 2.0 hub is powered by the external power source if you connect one.

ZWO ASI294 Color CMOS Telescope Camera

4/3″ format, 14bit ADC, 63700e full well.

• Planetary and Deep-Sky Imaging.
• Pixel Array: 4144 x 2822.
• Pixel Size: 4.63 microns.
• Sensor: IMX294CIK.

The ASI 294MC is the first camera with the latest Sony IMX294CJK sensor: the ideal astro camera for every conceivable application! The "back-illuminated" Sony CMOS sensor ensures maximum sensitivity and therefore short exposure times. With just 30 seconds of exposure time and subsequent stacking, you'll be able to capture faint nebulae and galaxies with this camera - without any active cooling! The main advantages of the camera at a glance: USB 3.0 for a fast download - can also be operated with USB 2.0 Very sensitive CMOS sensor: quantum efficiency in the maximum over 75% (about 530nm) Good resolution due to relatively small pixels Supplied with AR clear glass filter, which means full passage also in the infrared. If the IR is to be blocked, an IR cut filter is needed. HCG mode - if Gain (pre-amplification) is higher than 120 (12 db), the readout noise will be reduced below 2e - Result: Despite extremely high sensitivity, you will obtain low-noise images. High full-well capacity: even bright stars do not burn anymore, they get a better signal-to-noise ratio. Big scope of delivery: adapters, cables and more
