My astrometric configuration is a Celestron C-8 and a Van Slyke Digital Bifilar Micrometer. The reticle lines are 10 microns, the digital readout has a resolution of 0.0005", and the 4" diameter position angle indicator has a 0.1 degree vernier scale. I machined a sleeve for the eyepiece so that I can mount a video camera.
