Great post...You hit the nail on the head. For my 114mm f/5 I use a 8 to 24 zoom and the 25mm ep I got with the scope. For a barlow I purchased a 3x Meade, but on good seeing nights I thought a little more magnification was possible and purchased a Celestron 2x but that turned out to be too much for the scope. So I flush sanded a filter case removing the male threads and glued it to the end of the 3x barlow and screwed in the lense module from the 2x barlow. So the 2x barlow is maybe a 1.5 and the field is flat and true. This also helped as the second barlow is now in side the focuser but nowhere close to the secondary. Cool because of this arrangment I am getting my money's worth out of this scope but getting there wasent easy. I should have read a little more on the subject before diving in, I would have gotten to the same place but much quicker...
