Nice one Doug, 5 hours worth hey,

bet you are pleased with that, very impressive mate.
Now there is still on thing that puzzles me, however I'm sure that it has been explained to me before, but forgive me I'm getting old.
I always thought that all exposures processed in Image Plus had to be of the same length,

but obviously, with the beauty you have produced that is not the case.
Please explain..????????
