New ideas:

I have thought of a way to improve the artificial star test.
I am lucky that I can focus at only 2 meters from the target with that Antares guide scope attached to the QHY9.

What I need is a simple cardboard tube 2 meters long painted black on the inside.
That would make it super dark inside & mimic as close as possible real dark conditions.
I could then paint some Aluminum foil black as well & make tiny holes in it.
I would also need a focus adjustment on the guide scope.
The LED light needs to have a variable power supply to alter the brightness.

I have proven the concept - & I might build the above setup.

cheers
