This should work with lasers as faint as 1mW when you look close to the telescope (due to legal <1mW limitations in NSW and VIC). And obviously not close to airports in any part of the world.

On another forum I read this tip.
Remove the eyepiece and shine a laser pointer into the barrel via the secondary on the primary.
When viewing close to the beam to the sky, the laser always points to the same part of the sky, regardless which part of the primary it hits when moving the laser in the eyepiece socket (unless you point beside the secondary).

I tested it, but with a brighter one. Indeed, I could point it exactly to a location in the sky and when I popped in an eyepiece (24mm Pan in a 400mm f/4.5 = 75x or 0.9 deg TFOV), the selected object was in the field.

Strangely I did the same test with my 80mm f/6.5 but the laser pointer moved inside a circle of 1-2 degrees when I moved the laser in the eyepiece socket. Weird.
