EP won't focus

Posted By Michael Rosen

PLEASE HELP!!!
A few weeks ago I purchased a 14 mm Explore Scientific 100° EP. Unfortunately, the EP doesn't seem completely compatible with my Orion XT 10 dobsonian scope. I've tried adjusting the primary mirror (to both extremes) and even bought an extension tube. The reason why I bought the extension tube is because sometimes I could get the EP to focus if I pulled it slightly out of the fully racked-out focuser.
Any ideas for what I should try next or try again?
