Honing my very blunt PixInsight skills by fiddling with old data. These are trials only of various pre-determined scripts.
Here is a single 20 minute sub of M78 with an FSQ-85ED and an OSC CCD. I tried the newly released "EZ Denoise" from the EZ Processing Suite script and was simply amazed what it could do with default settings alone! I am not a fan of denoise algorithms but this one seems rather good!

I imagine it will only be better on a fully integrated image, as I did notice some loss of detail in the dark cloud.
