thanks guys but i cheated with unsharp mask
the full size image looked a touch soft off the camera
since it didnt really work as planned i guess ill re-collimate further back the tube again and make do with the screw on fittings until i get a 10:1 low profile.
i guess all we can do is hope the skies are clear for the big event!
i missed the last one due to clouds so id be a bit upset if it was the same with this one.
