Hi Nick,
I confused myself in that previous post.
In fact I have to collimate the scope with the mirror higher in its cell, not lower, due to insufficient focuser IN travel when using the Paracorr on setting #1 with both the 14mm and 20mm Pentax XW's, which is where they work best. As you adjust the paracorr towards the lowest numbers it requires more in travel. Unfortunately, you can't compensate for this with an extension tube like you can when you have insufficient out travel. It doesn't need the mirror pushed up too far and you should be fine. There are fixes anyway, if it won't reach focus with some of your eyepieces. What focuser do you have ?
