Narrow Band combination
« on: 2014 October 12 10:42:09 »
Hi

I have bought a O3 filter to go with My Ha filter , I want to know when people combine this with their LRGB

I.e do you combine all when linear ( inc the Lum ) or it there a better way  8)

Any Ideas would be great

Hi Harry!
From my experience it depends on the quality of Ha and OIII and RGB.
If the qualitity is good i combine them in the linear stage.

I produced a video for this linear combination:

Harry and Gerald,

Off subject, but wanted to thank you both for your efforts.  I have learned so much from both of you and really appreciate your dedication. 

Best,

Jim

great video!  as a novice, I'm curious about the advantages of combining these subs in the linear phase vs. non-linear?
