I have a Borg 101ED that I would like to collimate indoors (30 ft) and not sure if either of these would work. I could put either in my backyard which would give me about 150 ft. Thanks.

Hi Dave,
I have had good luck with one of these for collimating scopes. The cost is very minimal.

Hi Dave,

I have one the those as well. It works very well.....better at night of course. I used it collimating a BRC-250 and had to get it about 60-75 ft away to begin to achieve focus. I usually used several extensions to help. It is a nice point source, but it is takes a bit of time to line everything up and get it in the field of view - with the pinhole in of line of sight.

Much better than just using a star....and you avoid all the seeing issues.
