Hi Col. I made my own using a torch covered with aluminium foil with pin holes in it. It works pretty good (I've also used a torch shining on a ball bearing). It'a lot easier(and less frustrating) collimating without having to track a star and not worried about seeing, weather etc.I have looked at buying the hubble artificial star torch (and probably will when have some spare cash) It gets pretty good reviews and I think is a bit cheaper than the one you're looking at. So ,yes either make or buy one as they are a good thing Col.
Cheers, Richard
