It is quite difficult to decide how much hydrogen can/should be boosted into the red channel. If you show hydrogen in all its glory, the RGB drowns in it. If you look for balance, all the beauty of the hydrogen is lost. Therefore I will post the hydrogen in all its glory separately.

I think I have finished processing this last year's accumulation. It is time for the accumulation that I recently brought from Mezmay!)
