There was a good post by Tamiji Homma last spring I was referred to (thanks catboat) that listed a lot of eyepieces and their respective focus distances that were measured with the "zero" point being somewhere in the middle of the measured ones (Pentax XW 20mm). Luckily one of my eyepieces I owned was on his list so I had a reference point for all of my eyepieces to compare to.
I turned "Tammy's" list into an excel file and added more information to it. The first 6 EP's listed are my own, after that the rest are the ones that were measured by Tammy in order of increasing required focus length. I also added other EP specifications I could find through some internet searches. At the bottom of the list is the avg. paracorr in-focus distance you need to subtract as well as the shoulder distances of several focusers in case you want to upgrade later. Some blocks are blank because either I didn't know what he was referring to or I couldn't find the information. Regardless I think that this list will be helpful to people trying to determine the placement of their focusers so that they can accomodate all future EP purchases.
FWIW the MAX drawtube travel needed (not counting different focuser base heights) including the use of a paracorr is 1.94".
Maybe we can turn this into a working list and get a true "Master" chart going as an eventual "sticky" post.
