Thank you Rodney. Your feedback is much appreciated.

At 100 hours of Ha, I think the result is what you're gonna be left with.... Which is EPIC!

Thank you for your encouragement Colin. Yes, I may actually need a larger aperture. One day...

I thought your attempt at the Helix is fantastic

Thank you Dave - I was dreaming of showing those shockwaves a bit more clearly.

We agree that it's technically impossible with an 8 bit screen to show both the outer details and the "eye" without making it look flat. The fault is with the manufacturers of computer screens. We need 16 bit OLED screens.
Superb.

Thank you Mike and Trish. I use your Ha Helix as a benchmark, as your Helix shows everything so well - data and processing both are top notch.
I think I previously estimated that the outer shockwaves register only one photon per pixel per hour of exposure with my 4" guide scope-camera combo, but will check that estimate later.
Maybe I should chuck in another 50 hours of Ha with longer subs
Just as a modification to the original experiment
