ZWO ASI533MM Pro: Next-Generation Powerful Monochrome Astronomical Camera
ZWO has gone a step further with this new camera. The monochrome sensor with a diagonal of approximately 16 mm can be used in almost any telescope. Due to the square shape, the corrected image field of the telescope is used optimally. With many telescopes, this even allows them to be used without a corrector.
A special feature of the ASI533MM Pro is the zero glare circuit, which eliminates amp glare that occurs with longer exposure times. With longer exposure times, this would brighten areas of the image. In this camera, the electronics also reduce the effects of external stray light, so you can expose longer under light-polluted skies.
One of the standout features of the ASI 533MM Pro is the sensational light sensitivity. The 80% QE thanks to the BACK ILLUMINATION technology and the very low amplifier brightness make the camera very suitable for all astronomical applications, but especially for deep sky astrophotography.
♦ Deep sky recordings (nebulae and galaxies): Due to the high sensitivity, nebulae and galaxies are captured after a few seconds. The camera can be cooled down to 35°C below ambient temperature. This further reduces the already low noise level. By increasing the GAIN (comparable to the ISO setting on digital SLR cameras), you can reduce exposure times to less than 30 seconds. This eliminates effects caused by air turbulence or tracking inaccuracies. So you can create deep or narrowband L-RGB fog images in just one night.
♦ Lunar and planetary imaging: Extremely short exposure times due to high sensitivity freeze air turbulence. Due to the high resolution of the sensor, highly detailed images can be obtained even with a shorter focal length telescope. Video astronomy is also possible.
back lighting technology
Sony's back-illuminated CMOS image sensor improves sensitivity and noise reduction, key factors in improving image quality, while the basic pixel structure has been radically reoriented from front to back exposure. The advantages of CMOS image sensors, such as low power consumption and high operating speed, have been retained.
Postexposure improves light capture while increasing the amount of light. This makes significantly shorter exposure times possible and leads to an improved quantum efficiency of 80%.
Sony has developed a unique photodiode structure and on-chip lens optimized for back-illuminated structures, resulting in higher sensitivity and lower non-light random noise by reducing noise, dark current, and defective pixels compared to traditional structure with front lighting.
No amp glow
Conventional CMOS sensors produce a faint source of infrared light during operation, which can often be seen in the corners of uncalibrated images as a telltale sign of "amplifier brightness." Because the ASI533MC Pro uses a zero amp brightness circuit, you don't have to worry about amp brightness or amp brightness even when using high-gain, long-exposure imaging.
Important: external power supply required!
Please note that all ZWO cameras with cooler must be connected to an external 11-15V power supply to work.
Even when the cooler is not in use, power must be present for the camera to be recognized reliably.
TS Tip 1: 2" Filter Integration, 360° Rotation & Quick Coupling
The chamber is often used in concealers that do not offer a filter thread. Also, filters should always be used as close to the camera as possible. We offer you a solution that can do much more.
♦ 2" filter holder directly in front of the chamber
♦ 360° rotation for the correct selection of the image section (less important here due to the square format)
♦ Quick Disconnect - You can remove the camera from the telescope at any time without screwing or tangling cables
The adaptation is very simple, the 21 mm T2 extension is replaced by:
♦ 1x TSROTT2-T2 and 2x T2AbstimmA1
One tuning ring goes on the camera side, one tuning ring goes on the telescope side of the rotator. Then screw in the adapter M42-M48 with a length of 16.5mm and it will be at the correct distance with the camera..
TS Tip 2: Camera and Accessory Storage
Especially in our latitudes, the nights are usually very humid. This moisture condenses on your camera, eyepiece, or filter as they enter the warm interior of the apartment. Cold rooms in particular are affected. A photo session ends quickly because the sensor freezes.
Good storage is an important prevention against dew and also prolongs shelf life.
After use, put the camera into the TS Protect case and add some silica gel. During storage, the silica gel absorbs moisture from the chamber. At the same time, the penetration of moist ambient air is prevented. Due to dry storage, even small dry tablets can be partially regenerated with cooled chambers. Your camera or accessories are always ready for you in optimal conditions. You can find the silica gel and the case in our product recommendations.
