ZWO ASI071MC PRO Cooled - Peltier-cooled Color CMOS Camera for Astrophotography
ASI cameras stand for a very good workmanship and feature up-to-date CMOS sensors. Now, ZW Optical makes these outstanding cameras available for deep-sky photography, too. A powerful Peltier cooling provides cooling up to 40 °C below ambient, allowing smooth exposures without noise.

With 28.4 mm sensor diameter and 4944*3284 4.74 µm pixels, the ASI071MC Pro color camera offers high detail resolution with a large image field at the same time. The sensor has a similar diagonal as the one of APS-C format DSLR cameras, but it is far more powerful.

With this, you can photograph an entire galaxy cluster and show details of the single galaxies at the same time. The camera is especially suitable for fast, high-resolution optics like apochromats or FastStar systems. Even with shorter focal distances, outstanding astro images are generated.

Large sensors with, in comparison with DSLR cameras, rather fine pixels require good adjustment to avoid tilt between sensor plane and image plane. For this, the ASI071MC Pro has an adjustable connection plate which makes an additional adjustment flange with its optical path obsolete.

The "single shot" color camera offers more comfort, compared with MONO cameras. Not everyone wants to follow through the laborious L-RGB technique for beautiful colored nebula images. The color cameras offer a possibility to get beautiful images without changing filters. However, good broadband nebula filter (see accessory recommendation) reduce stray light and enhance contrast without the necessity of being changed or coloring the image too much.

Advantages and features of the ASI 071 PRO camera:
USB 3.0 for a fast download - can also be used with USB 2.0
DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port.
Powerful Peltier cooling up to 40 °C below ambient temperature
Sensitive modern SONY IMX071 CMOS sensor with 28.4 mm diameter - 16 megapixels
High resolution through 4.78 µm pixels
Shutter: Rolling Shutter
Distance from T2 connection thread to camera sensor: 17.5 mm
Adjustable connection plate - locked against unintended unscrewing
Comes with AR-coated clear glass window - full transmission even in infrared. If IR should be blocked, an IR blocking filter is necessary.
Anti-dew heating integrated against icing (feature of the new PRO series)


Application ranges of the camera:
Deep sky images (nebulae and galaxies): Due to the high sensitivity, nebulae and galaxies are captured after only a few seconds. By cooling down the camera up to 40 °C below ambient, the already low noise can be further reduced. By increasing gain (like the ISO setting of DSLR cameras), you can reduce exposure times below 30 seconds. Effects from seeing or inaccuracies of the drive are eliminated.
Lunar and planetary images: extremely short exposure times (due to high sensitivity) freeze the seeing. Through the high resolution of the sensor, many details can be reproduced even at shorter focal length. Video astronomy is also possible.


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 by Teleskop-Service before and after purchase:
We work with the cameras ourselves and can offer you optimal advice. Which camera matches your telescope, how do you achieve optimal adaption ...

Teleskop-Service is one of the biggest ZWO dealers. Due to our contacts, we offer best possible service also after 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.
2" filter holder directly in front of the camera
360° rotation for the right choice of the image section
Quick release - you can remove the camera from the remote ear at any time, without screws and thus entangling the cables


The adaptation is very simple, the 21 mm T2 extension is replaced by:
1x TSROTT2-T2 and 2x T2AbstimmA1


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.

Last Tuesday, Wednesday and Thursday, I have exposed 126 times for 300 sec each. The last two days included a meridian flip, too.

After the meridian flips, I had only one guiding star at the very edge of the image, even with the Lodestar X2. Thus, and also due to the three days for the exposure sequence, a certain image shift was called for. I have cropped the slight waste, as the gradient removal at the transitions would have made trouble.

I have inserted the desiccant tablets and screwed the holder. Then I have worried thet the desiccant would become effective not before 24-48 hours. However, I directly cooled down to -15 °C without ice formation on the sensor. It seems that the CMOS chamber was dehumidified at the factory.

I was able to use the ASI071 without refocusing the Lodestar, so back-focus identical to ASI1600.

I had a slightly hard time when installing the drivers. First the software insisted on the deinstallation of all kinds of old ASI drivers, only for subsequently not recognising the camera. Finally, a restart of the notebook worked, which, as dar as I remember, was not necessary with new Windows versions. Maybe I dont´t remember correctly here. At least, it worked now.

I have worked only with Unity Gain. The bias exposures have values about ADU 100, nevertheless all weak objects seem to be shown. With identical light source and similar ADU exposure (about 38000), the flats require 3x the exposure time as the ones of the ASI1600. As "full well" of the 1600 is at approx. 4000 with Unity, and at approx. 15000 for the 071, this matches. Obviously ZWO has not occupied the lower bits (4 at the 1600, 2 at the 071) here.

The cooling down time of the 071 is similar to the 1600, likewise the displayed cooling power. From 9 °C to -15 °C approx. 20%, from 22 °C to -15 °C approx. 65% (tested when making bias, darks and flats in my home). In stationary cooled state, the temperature display jumps back and forth between -14.8 and -14.1, sometimes also to -15.4 C (obviously no control, only display fluctuation).

The sensor surface of the 071 is clinically clean, in opposite to the 1600.

The two USB ports of the 071 work properly. On one of them, I use the Lodestar X2 and on the second one the USB AO.

The image download times are similar to the 1600, also the FITS file size of 32 MB; they both have 16 MPixels. ROI selection for focusing works exactly like with the 1600.

The fan can hardly be heard.

The setting of the heating of the optical window was activated in the ASCOM dialogue window, which I didn´t notice. I had no problems with condensate at the window, so the check mark was left set.

The 071 did not show any visible amp glow, different from the 1600 where this effect was visible in the stacked summary image.

Overall, the ASI071 seems to me to be a well usable and "easy-care" APS-C camera. It is fun to photography with it.

Experience report: first light with the ASI071C cool
The camera is great!

Basically, a one-shot camera replaces a DSLR like a Nikon or Canon. The drawback of the latter is that the DSLR has to be converted first - for example, the IR filter has to be removed first. If I compare the ASI071c with my Canon 600d, some advantages are instantly visible.
Fist the chip size: for the Canon it is 22.6 mm, whereas it is 28.4 mm for the ASI ? and that despite clearly smaller pixels!
Then the chip of the ASI has less noise and can be cooled furthermore. In my case, 36 - 37 °C below ambient temperature was possible. However, the camera demands a lot of electric current for this. Insofar, it is advisable not only to connect a 12 V supply, but also to use the USB 3.0 port instead of the USB 2.0. Here you have approx. twice as much current at your disposal.
A further advantage is the full well capacity. In opposite to the Canon with approx. 13,000 ? 14,000 electrons, you get to 46k with the ASI ? considerably higher dynamics.


If you look at the outside of the camera, you see that ZWO thinks along. The built-in USB port is also supplied by the 12 V power supply. Fortunately, a short USB cable is included, which can be used for connecting the guidung camera. You save a further cable to the notebook - a genial solution.

An adapter for levelling a tilted chip is attached to the front side.

"Great ccd camera used for DSO IMAGING ON A Meade LX90 12?. Excellent for what I want to achieve!"

Written by Mike Vogel

"Die ASI071MC pro ist meine erste Erfahrung mit gekühlten Astrokameras. Davor habe ich mit DSLR (EOS600D) und micro43 (OM-D E-M1 MarkIII) fotografiert. Meine Erwartungen erfüllt die Kamera 100 prozentig. Geringes Rauschen, hohe H-alpha Empfindlichkeit, kein sichtbares Verstärkerglühen und bisher auch keine Problem mit Betauung, trotz hoher Luftfeuchtigkeit jetzt im Oktober. Für mich ist die Kamera ein guter Einstieg zu einem vernünftigen Preis."
