High accuracy collimation using CATSEYE collimation tools
This is the basic procedure for obtaining precise collimation using the
TELECAT sight tube/Cheshire tool and INFINITY autocollimator.
I DO NOT ENDORSE ASA TELESCOPES! In fact, the one I purchased (featured in this sequence) was a bad finacial decision on my part as it exhibited a number of failings and faults including bad astigmatism so after a long wait for its arrival and then much heartache and dissapointment, it was returned.
This collimation sequence continues to be made available on my site for the benefit of Newtonian Telescope users World Wide and in recognition of the excellent tools Jim Fly produces.
