ZWO ASI533MC Pro - powerful color astro camera of the latest generation
ZWO has taken another step forward with this new camera. The colour sensor with a diagonal of approx. 16 mm can be used on almost every telescope. Due to the square shape, the corrected image field of the telescope is optimally used. This even allows the use of many telescopes without a corrector.
A special feature of the ASI533MC 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. Especially with this camera, the electronics also 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 533MC Pro is its sensational light sensitivity. The QE of 80% by the BACK ILLUMINATION technology and the very low amplifier glow make the camera very suitable for all astronomical applications, but especially for deep-sky astrophotography.
The "single shot" colour camera offers more comfort than monochrome cameras. Not everyone wants to go through the laborious L-RGB process for beautiful coloured nebula or planet images. The color cameras offer you the possibility to get beautiful pictures without changing filters. In direct comparison to the DSLR camera, the ASI camera convinces with a much higher light sensitivity, a smoother image and significantly more depth. Stars don´t burn out that easy.
Further advantages and product features of the ASI 533MC Pro color camera:
Application areas of the camera:
Back illumination technology
Sony´s back-illuminated CMOS image sensor improves sensitivity and noise reduction ? the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. It has retained the advantages of CMOS image sensors such as low power consumption and high-speed operation.
The backside exposure improves the light absorption and increases the amount of light at the same time. This allows significantly shorter exposure times and leads to an improved quantum efficiency of 80%.
Sony has newly developed a unique photo-diode structure and on-chip lens optimized for back-illuminated structures, that achieves a higher sensitivity and a lower random noise without light by reducing noise, dark current and defect pixels compared to the conventional front-illuminated structure.
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 ASI533MC 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 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 1 from TS: Integration of 2" filters, 360° rotation and quick coupling
The camera is often used on correctors that do not have a filter thread. In addition, the filters should always be used as close as possible to the camera. Here we offer you a solution that can do much more.
The adaptation is very simple, the 21 mm T2 extension is replaced by:
One tuning ring comes to the camera side, one tuning ring comes to the telescope side of the rotator. Then screw on the M42-M48 adapter with 16.5 mm length and you are in the right distance with the camera.
Practical tip 2 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.
The cameras are not airtight, so if the camera remains on the telescope, it is exposed to moisture. The small amount of desiccant in the camera can protect the sensor and the inside of the protective glass from moisture for the duration of the exposure, but not for days on end. Moisture problems can be the result. A simple trick is to stretch a plastic bag around the focuser to which the camera is attached so that no air can get in. Silica gel is placed in a small cloth bag inside the plastic bag. This will also create a "dry climate zone" for the camera on the telescope. This allows you to leave the camera on the telescope for a few days for an imaging session lasting several days.
In the medium and long term, however, this is no substitute for proper storage in an airtight case with silica gel.
