P.S. Milton, The farthest distance I can use in the yard here is about 80-100 metres. Would this be far enough away to adjust the offset of the finder with the camera? The problem with this is that this offset then has to be taken into account when doing the 3 star or whatever.

..The only option I have for guiding at present is the DBK.(the Flea 2 is on it`s way to Canada) Because of the problem with the Scorpion not sharing the Firerepeater 400 yet I`d have to guide using the Mac Mini & probably my long cables...So it`s quite a complicated proceedure even before I make my first attempt at a guiding app. (whichever I try first..!?)

Mark;

Talk to the developers of those packages ( Equinox Image and iCCD) and
see what they say. They know more about them than I do.

If it's a camera not supported by Astro IIDC, then I don't have an
opinion on it. All I'm talking about is the Grasshoppers for 15+
minute exposures and your not getting a good bang for the buck with
them. Maybe the Grasshopper 2 will be better, but who knows.

And maybe you should learn how to do 1 minute Guided exposure first
before running off and spending $2 to $8K USD on more cameras.
