I had in the past a 5mm Hyperion. Not all 5mm eyepieces wil focus at the same point...that is some have more intravel and some need out-travel.

My suggestion is to use the 5mm without the adaptor and see where it focuses with the focuser racked all the way in...seems like you need a few more mm in than you can get with the SW 1.25" adaptor.

Hopefully someone with the same scope will answer too.
