Does Deconvolution with OSC images require extraction of pseudo-Luminance

[javajunkie2121]

Hi:

was watching the IPAP tutorial on PixInsight deconvolution...I have OSC images...do I need to manually extract a pseudo-luminance component out of the OSC single image to use deconvolution and other processes that primarily effect luminance? Or do I stay with the single image and the process works on the luminance component?

Thats what I do.

No it is unnecessary in my experience.  The tool has a 'Target' dropdown where you can select either 'Luminance (CIE Y)' or ;RGB/K Components' as the the target for the process without needing to extract the luminance to a separate image.

A lot of the 'make a pseudo luminance' processing is driven by the use of PhotoShop and similar, whereas most of the operations that need to target a specific component can do so in PI without splitting the image.
