ZWO ASI533MM Pro - powerful mono astro camera with the latest generation sensor. This monochrome sensor with a diagonal of approx. 16 mm can be used on almost every telescope. Due to the square shape, it even allows the use of many larger telescopes without a corrector.
A special feature of the ASI533MM Pro is the zero-amp glow circuit, which eliminates the amplifier glow that occurs with longer exposure times. This would brighten areas of the image at longer exposure times, particularly around the corners. The electronics are also designed to reduce the effect of external stray light, so you can take longer exposures under light-polluted skies.
One of the outstanding features of the ASI 533MM Pro is its sensational light sensitivity. The QE of 80% thanks to back illumination technology along with the very low amplifier glow make this camera very suitable for all astronomical applications, but especially for deep-sky astrophotography.
Advantages and features of the ASI 533MM Pro 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 - This minimizes amplifier glow
Powerful Peltier cooling up to 35°C below ambient conditions
One of Sony´s most light-sensitive CMOS sensors
High resolution by 3.76 µm pixels - ideal for fast and sharp telescopes like APO's, Hyperstar, Celestron Faststar, Newtonian telescopes etc.
Supplied with AR clear glass filter - full transmission 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: 17.5 mm
Distance front surface to sensor (using male thread): only 6.5 mm
High sensitivity - QE over 80% - ideal astronomy camera for low-light objects
14-bit ADC. Similar depth to CCD cameras, but with a much higher sensitivity.
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 35°C below ambient temperature. By raising the Gain level (comparable 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 tracking are therefore dramatically reduced.
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 'Lucky Imaging' astrophotography is also possible.
Back illumination technology: Sony's back-illuminated CMOS image sensor improves sensitivity and noise reduction, which are the key factors to enhancing image quality. This retains the advantages of traditional CMOS image sensors such as low power consumption and high-speed operation.
This allows significantly shorter exposure times and leads to an improved quantum efficiency of 80%.
Zero amp glow: Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images as the tell tale signs of 'amp glow'. As the ASI533MM Pro uses zero amp glow circuitry, you won't have to worry about amp glow even when using high gain, long exposure imaging.
Important: external power supply required! Please notice that all ZWO cameras with a 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 operate.
Good storage is an important factor in the prevention against dew and also extends the life span of the camera. Always ensure your camera is stored in a cool dry place and any excess moisture from dew or frost is removed.
