I have a vixen102M 4" f9.1
when I bought it it had the option of the 2" end section as well as the 1"1/4 it had already attached I recently purchased a nice 2"mirror diagonal so I could try this extra section but to my dismay I cannot actualy get a proper focus the focusser is wound in as much as it can this be with 2" eyepiece I have or any of the many 1"1/4I have it gets no better if using a barlow the focusser still cannot quite get there
anyone got any idea ???
I can post pics if this would help
