Maybe there is a better way to explain this & better questions to ask:
My problem is not having enough inwards travel on my draw tube for one eyepiece in particular, the 20mm Superview. It's almost in focus but, not quite & the draw tube won't go in any further.
Am I right in thinking that I need to somehow shorten the light path for this EP to come to focus?
Would a change to a 1.25" diagonal achieve this?
Would a recessed 1.25" adapter achieve the same thing?
Is my scope just not good with a 20mm 1.25" EP?
Why does my scope have 120mm of focusser tube travel if, when using EPs it only uses the first 20 - 30mm?
Is there potentially something wrong with the scope??
Are my eyes that screwed up??
