I want to use the tracker with my 201XT as the guider. The gentlemean at
taurus tells me that it should work fine. Am I reading their literature
correct when they say that the focus distance in the eyepeice is the same as
the distance to the film plane? So I would see, for instance, m57 in a 6mm
eyepeice, focus it as nearly perfect as I can and that focus will be the same
focus as that of the camera? I will ask them to assist me in choosing the
proper port adapters based on my needs and expected growth. I must admit only
you have given the tracker a favorable reveiw, yet I seem to get the impression
it is somewhat reserved due to the autoguiding deficiencies. My goal is to
autoguide extensively.
Thanks (You web site looks great)

I want to use the tracker with my 201XT as the guider. The gentlemean at
taurus tells me that it should work fine. Am I reading their literature
