Henry Link just suggested (on another thread) that Polaris makes a good star that doesn't move much.
My next try at an artificial, I think I might place it over 200m away. Single small LED light. (a big reflector or
lens is not good). You may want to boost 20x to a power equal to or over your aperature in mm
(approximately), I am told. Most monoculars are too powerful. 4x is useful, or 6x.
Low-vision supplies places have nice low-powered monoculars, the 4x12s here:
