ZWO ASI220MM Mini Monochrome Camera

Probably the most sensitive ZW-Optical autoguider for astrophotography with a modern Sony sensor and a 1.25" housing.

♦ Sony SC2210 MONO CMOS sensor with a maximum QE of 92% and a pixel size of 4.0 µm for maximum sensitivity: always find a guiding star.

♦ High NIR sensitivity, reducing effective air turbulence

♦ Sensor size 7.68 x 4.32 mm

♦ Handy 1.25" housing: you can use the autoguider/camera as an eyepiece in the guide tube, viewfinder or off-axis guider.

♦ At only 60 grams a really light weight and no bigger than a 1.25" eyepiece

♦ Extensive scope of delivery: protective cap, instructions, 2 USB cables, ST4 autoguider cable, CS mount adapter and 1.25" extension sleeve

♦ You can also use the camera as a high quality lunar and planetary camera.Thanks to the high-sensitivity sensor, it is even possible to take pictures of deep sky objects.

Incl. CS threaded adapter for connecting lenses and T2 adapter

This camera contains a 1/1.8" (7.68 mm x 4.32 mm) SC2210 sensor. It is a monochrome guide camera with excellent near infrared sensitivity. This camera has a pixel size of 4.0 µm * 4.0 µm in a 1920x1080 matrix and a full well capacitance of 8780 e-. The protective window is

aR coated. The ASI220MM Mini can be seen as an improved version of the ASI290MM Mini, featuring a larger sensor format and larger pixels with better NIR sensitivity.

♦ Due to the high light sensitivity, it will always find a guide star, even with off-axis guidance, guaranteed!
♦ Convenient 1.25" housing makes it easy to adapt. Insert the camera into the 1.25" mount, focus and start.
♦ Only 8.5 mm working distance from the front edge to the chip, so you can focus even at close distances.
♦ Weighing only 60 grams, the focuser is barely weighted.
♦ ST4 cable and ST4 port, of course, are included.Connect the camera directly to the mount's autoguider port.

Autoguidance software is not included.The camera is ASCOM compatible and suitable for, among other things, PHD Guiding, Guidedog, Metaguide, Guidemaster (freeware), APT or AstroArt, MaxIm DL (fee-based).

♦ High sensitivity sensor for good lunar and planetary photos.
♦ High frame rate in the
planetary range ♦ Camera fits into any 1.25" focuser. Hold the camera like an eyepiece, focus and start astrophotography.
♦ Due to the high sensitivity, the ASI220MM Mini is also suitable for photography of nebulae and galaxies
♦ The camera is equipped with a transparent glass filter, which is also transparent in the infrared range, making exciting infrared photography possible

Spectral sensitivity

The sensor impresses not only with its high sensitivity, but also with its wide sensitivity range.Sensitivity remains high in the deep infrared.This means more stars to guide and the exciting range of infrared photography (Venus, Mars...) becomes possible.

That's how compact the ASI220MM Mini camera is:

Compared to other astronomical cameras, the ASI220MM Mini has smaller dimensions, less weight and reaches the focal point at the same point as an eyepiece.

What is included?

The ASI mini camera package contains all necessary cables, drivers, adapters and also a manual (in English).

Mini cameras have beautiful appearance, small dimensions, low weight, these are already attractive features.However, the cameras impress with other advantages:

High sensitivity: important for finding the guide star
Sensitivity is the first thing on your mind ZWO with these cameras.Finding a guiding star is very important.Therefore, at the beginning, ZWO only considered a black and white sensor for use in their tracking cameras, as a monochrome sensor has a much higher sensitivity than a color sensor.The manufacturer then carefully compared the sensitivities of the available sensors.Finally, ZWO decided to use SW sensors.The monochromatic sensor of the ASI220MM Mini has a maximum quantum efficiency of approximately 92% and can therefore perceive more stars in the field of view.In this way the exposure time for guiding can also be shortened.

Focusing position as with eyepiece

ASI Mini and eyepiece can achieve focus at the same location.You can focus with an eyepiece and then plug the mini camera into the 1.25" barrel. Works


in OAG

Mini cameras ZWO are ideal for tracking with OAG, they have a much larger focusing range than normal ASI cameras. You no longer have to worry about the tracking camera not being able to focus at the same time as the recording camera.
