Re: [APML] needed- an excellent sense of direction

I modified my astrosystems laser collimator to improve my pictures.. all I did
was to reduce the laser dot size to a pinhole.. literally a pinhole.. I placed
some aluminum duct tape over the laser, painted it flat black and then
perforated right over the laser diode with a pin.. the resulting small dot
improved my collimation tremendously, no more elongated stars in the corners..
