well, it looked like professionaly made, but you did
tell me that you made it.

I still think that laser collimaters are best in open
tubes. in closed tubes, the cheap way is better, and
more accurate. If the telescope has a short focal
length, then the secondary is usually larger, and
there is more chances of the laser being not exactly
in the middle. If the tube is open, I think Laser
collimaters rule.

Thanks, Asaf.
