ZWO ASI 294MM Pro Cooled Mono Astrophotography Camera

• Perfect for deep space astrophotography and planetary imaging!
• 11 MP micro four-thirds sensor.
• Thermoelectric cooling down to minus 35 degrees Celsius below ambient.
• Shoots 4k video at 24 FPS and 320 x 240 at 179.3 FPS.
• Thanks to the back-illuminated sensor, this camera has improved light-gathering power compared to its front-lit counterparts.
• This camera has a bit-depth of 14 with 4.53-micron pixels for extremely detailed images.
• High QE around 90%.

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.

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.

• Anti-dew heater to eliminate condensation and ice buildup
• Anti-amp glow circuit to reduce long exposure amp glow
• 128 MB DDR memory to speed up download times

QHY5L-II-M CMOS Planetary Monochrome Camera - QHY5L-II-M

Do you want to get started in astrophotography and are you searching for a color camera simple to use, compact, cheap but with high quality to photograph the planets and the Moon? The QHY5L-II color is the perfect camera for you. The sensor has a very good 1280 x 960 pixels resolution, allowing you to record, with the EZPlanetary software, excellent high-resolution images.

Although less sensitive than the same camera with monochrome sensor, the QHY5L-II color can also be used as a autoguider thanks to the integrated ST4 port and to the autoguide cable already provided in the package.

• Aptina One-third Inch MT9M034 CMOS Sensor.
• Pixel Array: 1280 x 960.
• Pixel size: 3.75 um.
• USB and ST4 interface.
• QE of 74%.
• Planetary, Solar and Deep-sky Imaging.
