I've been looking around trying to figure out what modifying a PST really means and It seems you just need to couple the PST back end to another scope with a decent apature. Correct me if I'm wrong.
To that end, what is the coupling between the PST back end and the scope it comes with?
Why not sell the pst and buy a 60mm Lunt while our exchange rate is good - higher contrast, crayford focuser, more uniform image, an all around better instrument. Give Sirius Optics a call for a price - you might be surprised.
