During the “brainstorming” session of the PixInsight Workshop at the Torre del Sole on May 27 and 28, 2017, I was asked for advice on how to process an image of NGC 891

The image is an LRGB capture taken from the city sky of Manerbio by my friend Alberto Crescenti.

We decided to record all the phases of the processing with a tool to capture the video and audio output: the result was a small video guide that could be interesting for others too.

for the LRGB composition I used my IRGB method explained in the article LRGB composition in the linear stage

I therefore share the video uploaded to YouTube, hoping it can be useful to many.
