Counting Electrons with CaLIGHTs v3.1.6

Starting with CaLIGHTs V3.1.6 it is now possible to select a custom output pedestal value. This creates an interesting opportunity to study your astrophotos at the electron level. You can now determine how many electrons have been collected at any given location in your astrophoto. You can also evaluate how much the CaLIGHTs noise filter can dramatically improve your astrophotos. One piece of information you need to determine is the system gain of your camera. The system gain tells you how to convert the pixels values into electrons. This can…
