Features

  • The ZWO ASI120 Mini Monochrome CMOS Camera is one of their most popular guiding and planetary cameras due to its reasonable price and advantages for guiding.
  • Uses the AR013CS 1/3" CMOS sensor with a 1.2mp (1280x960) resolution and 3.75µm pixel size.
  • Compatible with USB 2.0 interface.
  • Quantum efficiency is almost 80% which is more than sufficient for most guiding purposes.
  • Analog to Digital Conversion A/D is 12-bit, enough to accomodate and pinpoint different levels of brightness for each pixel without loss of data.
  • Read noise of 4.0e, low enough to detect signal difference enough to guide properly.

Quantum Efficiency near a peak of 80%

Quantum effiency is the blueprint of the effectiveness of any sensor and is one of the most important factors to determine its effectiveness for image capture. It reveals how much of the photons that hit the sensor are then converted into electrons. In the case of the ASI120 Mini camera, measurments have shown a near 80% QE peak which is remarkable for a guide camera.

Full Well Capacity of 13,000e

While quantum effiency measures how effective a sensor is at converting photons to electronics, that is only the first part of the equation. The full well capacity is what determines the amount of charge that can be accomodated within each pixel before any saturation may occur. Why is this important? Because if pixels cannot accomodate any more charge, signal becomes degnerated and the sensor cannot process accordingly. The ASI120Mini has a measured full well capacity of 13,000e which is perfectly in line with the amount of signal a guiding camera would need to pickup.
