About this product
Part Number: ASI120MINI
Compatible with the new ZWO ASiair
The ASI120MM Mini is a very capable guide camera that can handle most setups with ease, including most OAG configurations.
Peak QE of 75% (better than the ICX618) and no Fixed-Pattern-Noise!
Supports 35 FPS at it's maximum 1280 x 960 resolution and long time exposures up to 1000s!
Compared to ICX618 based cameras the ZWO ASI120MM offers faster frame-rate, slightly higher sensitivity in visual light and more pixels for lunar imaging.
The sensor is protected by an anti-reflection clear optical window. If imaging the Moon or planets we recommend fitting a 1.25" UV/IR rejection filter.
The ASI120MM’s mono sensor can also be used with specialised UV or methane band filters, as well as infrared passing filters for lunar and planetary imaging (i.e. Baader IR-Pass, Red and Orange visual filters). IR-passing filters cut short wavelengths which prevents atmospheric dispersion softening the image.
Note: The ASI120MM has a Micron sensor which might produce Newton Rings when used with solar telescopes. (Cameras fitted with Sony sensors are better in these circumstances).

ASI120MM Mini vs ASI120MM-S
Compared with the ASI120MM-S camera, the ASI120mini is smaller, lighter weight, and it can reach focus at the same position as an eyepiece.
USB2.0 & ST4 Ports
USB 2.0 Port: The mini camera has one USB2.0 type C port. Type C is very popular in mobile phones and it is reversible so it doesn't matter which way around you insert the plug.
ST4 Port: To connect directly to a mounts auto guide port.
