Have you done this with your 72ED or am I reading it wrongly ?
Excellent result if so.
The second version with the synthetic green I think looks better.

Hi Kelvin

Yes, I did use my Skywatcher 72ED to take the image. I do live in somewhat dark skies. I'm around bortle 3/4.

I also like the synthetic green version also, really makes the image pop.

Well that's even more impressive then. Being 1000m up wont be doing you any harm either ! I stayed in Katoomba a night on my way down to Parkes for the 50th moon landing celebrations recently. Got my Star Adventurer & camera out. Twas VERY cold and windy so I didnt stay out long.
