In-focus question

Hi all,

Maybe this is a dumb question, but I couldn't find a direct answer from using a search.

Which eyepieces from any of the major lines require the greatest amount of in-focus? I'm designing a reflector for minimum focuser height and I want to be able to cover a "worst case" scenario. I figure I can always use an adaptor for EP's that require more out-focus.

In my collection it is UO orthos that require the most in focus but is there anything out there that requires more? Tak LE's maybe?

Sorry if this was answered a million times already.

Thanks,

Mike

Most barlows require some amount of in-focus to work. Just how much depends on the barlow/eyepiece combination.
