Deconvolution is one of a few multi-step techniques that is part of the standard image processing workflow. 

With the advent of BlurXTerminator... the case for using the native blind/iterative LR deconvolution is difficult to make. If you have BlurXTerminator, you might want to review those videos first. For those that are interested in getting deconvolution to work well I recommend watching the "Deconvolution Update of 2021", "Parametric PSF Deconvolution" and the "Deconvolution of OSC Data" (even if you use a "mono" camera). 

These videos are more than a simple step-by-step demonstration. They are an in-depth treatment of the topic. One feature of this tool called "Regularization" is covered in PixInsight Horizons (I consider it a more a complex adjustment.) The Deconvolution process' default values in combination with a mask are demonstrated here.
