Looking forward to seeing a longer exposure.

(We had even worse than trees in the way last night: a cable for the dome roof opening mechanism came unfastened and fell down into the path of the dome shutter as it opened, causing a very scary BANG in the pitch dark. So our observing session was zero minutes and zero seconds.)

Best,
Mike
Thanks Mike, Crikey that cable incident must have been a wakeup call for you! Blending Ha and RGB is always interesting.
I have previously used the Starizona method described here to avoid the dreaded salmon pink -

But it seems that Marco Lorenzi's method http://www.iceinspace.com.au/forum/s...d.php?t=138473 gives a more natural, better looking result, it did in this case anyway

Cheers
Andy
