This is of course a crucial ability when looking for a star to guide on. So, from the beginning, we were set on using monochrome sensors to design our guide cameras. Because monochrome sensors have much higher sensitivity than their colour counterpart. Luckily the ASI120MM Mini, ASI290MM Mini and ASI174MM Mini all have very high QE peak value - about 80%, which can detect more stars in view and shorten the exposure time in guiding.\u003c\/p\u003e\n\u003cp\u003eEach of the cameras have their own strength and depending on what you value in a guide camera, one might be better for you than the others.\u003c\/p\u003e\n\u003ch3\u003eEntry Level\u003c\/h3\u003e\n\u003cfigure class=\"wp-block-image aligncenter size-full\"\u003e\u003cimg loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-67493\" src=\"https:\/\/i.zwoastro.com\/wp-content\/uploads\/2022\/07\/bcb85fbfd1e1c9055954b74220c6a10d.jpg\" alt=\"ASI120MM Mini entry-level guide camera\"\u003e\u003c\/figure\u003e\n\u003cp\u003eASI120MM Mini is designed for newcomers, it is more affordable than ASI290MM Mini and ASI174MM Mini.

Unlike the human eye, a silicon sensor is very sensitive to light in the infrared portion of the spectrum, and that is a problem because infrared images are blurry as all get out. That means your nice, sharp visual light image is degraded by the addition of the infrared layer.
