Hi Houghy, thanks for the comments!
I actually was thinking of a mosaic, but then thought some Ha while the moon was still out.
But my aquisition computer is giving me some grief so I'm doing some problem solving at the mo....
So, once I sort the prob out, will do some Ha tonight.
Might bring out the knotts a bit better.
But then again the Grus Trio might be nice and leave the Ha till tomorrow night with the moon, provided the sky stays clear.... and pending the computer.
Aaah the joys

Cheers
Rich
