ok, so im an astronomer and want to atach my laser to my telescope, and after all this looking around i realised DX had some ok units that could actualy 'zero in' or align the dot/beam with your scope.
but, the green 20mw seem a bit dodgy and 'overpriced' (for DX).
so i though maybe if i buy a red one and then put a 5-30mw 532nm module inside. do you think either of the following are appropriate and wouldnt need too much force on removing the module.
