I've been using IC 405 and IC 410 as targets lately for the new Optolong L-enhance filter that just arrived.  The filter gives a strong H-alpha signal with dominant red or red-orange coloration in most processed images.  It was OK but I wanted something more subtle.  I split off the H-alpha and O-III using Sirl.  Then I emphasized the O-III in reprocessing and made the H-alpha a little gentler.  I tried to keep the sky background as natural as possible.  The top photo is what you tend to get from the L-enhance filter on these nebulae.  Below it is my version splitting off the O-III and H-alpha and working with layers etc. to emphasize the O-III and tame the H-alpha.  You may like the result, or not.  I tend to prefer the subtle shades that result. It wasn't until I created the tamer version that I think I can see a number of proplyds (proto-planetary disks) in both of these nebulae although someone will tell me its my imagination.
