Hi, I don't know of a 20mm 2" Meade eyepiece - are you sure it's not the 26mm Meade QX that may have come with the LightBridge?

If so, then you can have focus at the edges or in the middle, but not perfect for both. It has a nice bright & wide fields of view, but tends to show aberrations for the outer 30-40% of the view for fairly fast reflectors (f/5 or below).

And yes, with my LightBridge I also needed to have the focusser all (or almost all) of the way out to bring this eyepiece into focus. Make sure your focusser is travelling all of the way out (sometimes the tension and/or locking knobs on the Crayford focusser need adjusting). Another tip ... you can also affix your Meade EP slightly higher up in the focusser barrel .. see what that does.

My solution was to get a few Televue EPs ... cost some dollars, but they hold their value and might be worth a try ... especially if you use the scope a lot.

Cheers,
Jeff
