Great image Richard.
The long exposure time certainly paid off. As you mention the sulfur
channel, do you have that channel as a separate image somewhere? I know
how M27 looks in Halpha and OIII, but I don't have a clue about SII.
Actually I would love to see all 3 separate to see how it composes.
Anyway
Great work Richard
