Helix nebula Bicolour

when the clouds parted and the seeing was ... okay ... i managed to get this image. Image was taken in Ha and Oiii, i did take some Sii but decided not to use it. i included in this thread the last time i took this target, which would have been about 8 months ago. The equipment upgrades have definitely helped, but i think the biggest difference between the two is the processing. thanks in no small part to those on this forum who have put up with my constant questions but it looks like i am starting to see some results.

The main objective of this was to get a glimpse at the cometary knots of hydrogen gas at the boundary between the Ha and Oiii region. These are about the size of the solar system with the mass of earth. I simply don't understand why everyone doesn't find this absolutely fascinating!
