ZWO ASI183GT - cooled monochrome CMOS Camera for Astrophotography

The cooled ZWOptical ASI183GT has the modern SONY Exmor R BSI IMX183 monochrome sensor installed. With about 20 million pixels this camera belongs to the big CMOS astro cameras. The resolution of the camera is sensational due to the pixel size of only 2.4 µm. This makes the ASI183 particularly interesting for sharp and fast telescopes and camera lenses.
 

The integrated electronic filter wheel

The filter wheel offers space for 5 filters. The filter wheel accommodates mounted 1.25" filters and unmounted 31 mm filters.

Important Note: The thickness of a 1.25” filter must not exceed 7 mm (without male thread), and the male thread must be shorter than 2.5 mm to avoid the filter wheel striking the camera housing.
 

Further advantages and product features of the ASI 183GT monochrome camera:

♦ USB 3.0 for fast download - can also be used with USB 2.0
♦ DDR3 memory buffer for stable data transfer with USB2.0 - minimizes amplifier glow caused by slower data transfer with USB2.0.
♦ Powerful Peltier cooling up to 45 °C below ambient conditions
♦ One of Sony´s most light-sensitive CMOS sensors with 15.9 mm diagonal - 20 megapixels
♦ High resolution by 2.4 µm pixels - ideal for fast and sharp telescopes like apos, Hyperstar, Celestron Faststar, Newtonian telescopes, ...
♦ Supplied with AR clear glass filter - full aperture also in infrared. If the IR is to be blocked, an IR cut filter is required.
♦ Distance T2 connection thread (female thread) to camera sensor: 26.5 mm
♦ High sensitivity - QE over 84% - ideal astronomy camera for low-light objects
♦ 12-bit ADC
 

Application areas of the camera:

♦ Deep-sky images (nebulae and galaxies): due to the high sensitivity, nebulae and galaxies are imaged after only a few seconds. The camera can be cooled up to 45 °C below ambient temperature. This further reduces the already low noise. By raising the GAIN (similar to the ISO setting for digital SLR cameras), you can reduce exposure times to less than 30 seconds. Effects caused by air turbulence or inaccuracies in the tracking are thus eliminated.

♦ Solar, lunar and planetary images: extremely short exposure times due to high sensitivity freeze the air turbulence. Due to the high resolution of the sensor, many details can be imaged even with a shorter telescope focal length. Video astronomy is also possible.
 

Using additional filters, e.g. narrowband fog filter

The integrated filter wheel has 5 positions. We recommend assigning four positions with an L-RGB (Luminance, Red, Green, Blue) filter set. This will allow you to take high class color images. The 5th position can be occupied by a H-Alpha narrowband filter. This allows narrowband images of H-2 regions.

But if you want to take narrowband nebula images with SHO (Sulphur, H-Alpha and O-III) filters, then we recommend to keep the 5th position free. Between telescope and camera you can install an additional exchange possibility for filters with the TS-Optics filter drawers. For this you need the following items:

♦ TSFSLT2 filter drawer (filter holders are optional).
♦ TST2V5 5 mm T2 Extension
♦ TSM48-T2L

With these parts the camera sensor is again in 55 mm distance to the M48 thread or T2 thread of the corrector and you can now use any filters additionally.
 

Important: external power supply required!

Please notice that all ZWO cameras with cooler need to be connected to an external 11-15 V power supply to work.

Even when the cooler is not being used the power supply must be used for the camera to be reliably recognized.
 

Optimal support before and after the purchase through Teleskop-Service:

We work with the cameras ourselves and can offer you optimal advice. Which camera fits to your telescope, how do you achieve the optimal adaptation? Teleskop-Service is one of the largest ZWO dealers. Through our contacts we also offer the best possible service after the purchase.
 

Practical tip from TS: Storage of cameras and accessories

Especially in our latitudes, the nights are often very humid. This humidity condenses on your camera, eyepiece or filter when they come into the warm interior of the apartment. Especially cooled cameras are affected by this. Quickly a photo session is over because the sensor ices up.

Good storage is an important prevention against dew and also extends the life span.

After use, put the camera immediately into the TS Protect Case and add some silica gel. During storage, the silica gel will suck the moisture out of the camera. At the same time, the penetration of humid room air is prevented. Dry storage even allows the small dry tablets in cooled cameras to partially regenerate. Your camera or accessories are always ready for you in optimal condition. You can find the silica gel and the case in our product recommendations.
