![]() 3 of them are free, 1 is payware, but has a trial period to use. Details that get "lost in the noise" will be more easily visible, and the higher s/n ratio will allow you to push things more aggressively in post processing.īefore I start here is a list of programs that I use in this workflow. Stacking 16 images of the target will give you a signal/noise ratio 4x higher than that of a single image. In fact, the signal to noise ratio increases by the square root of the number of images stacked. Because most of the noise in a single image is random, if you stack a bunch of them, the signal stays the same, while the noise gets averaged out. ![]() Over the past several years, I have been using a processing workflow that involves stacking a bunch of individual images and then using a liberal use of sharpening. The bright parts of the image may look fine, but getting towards the moon's terminator background noise may take over making things look a bit crummy. ![]() It is also a high dynamic range target outside of a full moon. It can be tough to get the right focus, if the wind is up and the atmosphere isn't steady one side of the moon may be in focus and the other out of focus. A lot of you have tried to image the moon, and may be disappointed.
