That's very interested Bojan!
I'd often wondered whether a green laser would be optimal for this task, providing of course the laser module itself is centred accurately (I must chuck them both in the lathe one day and check, I can use the tail stock as an accuracy guage.
I always put my vision down to my lousy vision, maybe it's not just my eyes.
Though I very recently acquired a pair of early 70s 7x15-35 Hanimex binoculars, the zoom model, picked up from the local Salvation army for $20 in extremely good condition. I ummed and arghed, carried them around the shop for the 10 minutes I was in there then decided I'd bite the bullet and buy them.
I already owned 3 pairs of binoculars, one a cheap 10x 50 from Tool-King (from memory), OK for the low price, not great, one pair of Vision King 7x50 a fellow IIS member locally gave me, higher quality optics than the Tool King things and, a pair of field glassed owned by a former WWII Luftwaffe pilot and Major (WWII pilot field glasses), late friend and neighbour. I haven't compared them,
The little Hanimex however blew me away with the quality of the glass and from my research it seems I got very lucky.
One day I'd like a larger pair suitable for portable astro.
