1mm gap with my ody native ggts bases. i also have no way to measure the length of the threads. i was enjoying the ithaka so much on the jgg that i never even tried anything else

LOL
i will say the floating pin design of the new 510 cap is simply brilliant. the oddy never has hit so hard , even better that the old 510 gg only adapter that i have on my other ggts's.
i am really falling in love with the JGG.
im seeing a future that will require ONLY the JGG and a few atties in my travel bag. bringing extra devices might become a thing of the past.
the new spring loaded post AND the floating collection tank post AND the floating 510 post AND the telescope is really amazing. every device sort of, for lack of a technical term, floats into contact with each other. without adjusting the pin length on any of the atties.
we defiantly didn't have this in the past!
i new i should have ordered 2!

LOL
