Since I'm not home it's time to process the Helix data I collected using a dual NB filter and compare it to my other recent attempts
I've attached three images ... from L to R:
Image 1. First two sessions combined (UV/IR and UHC filter).
Image 2. All three sessions combined (UV/IR, UHC and dual NB).
Image 3. Session three only (dual NB filter)
Things I've learnt:
a Stick to APP and PS for now, PI is a monster!
b. In my quest to extract max detail, I've also over-sharpened the first two images. There's a delicate balance between detail and over-sharpening hence why I personally I prefer the third image as it's still detailed IMO but without too much sharpening.
