It was 4rs in R, 4hrs in G, 4hrs in B and 3hrs in L, so a total of 15hrs..... It was supposed to be 4hrs in each filter but I wasn't able to complete the data set with all of the bad weather this season in Spain. There was enough signal in what I had so decided to process incomplete..... I did actually process fully the RGB before I finished collecting the Luminance but decided to continue grabbing more for it as I though it would benefit.
There is a clear difference in noise between the RGB and the LRGB... Deconvolution seemed significantly better on the actual Luminance over a pseudo Luminance I created showing less artefacts.
