Thanks for the links...I'll learn what I can so as to better understand the responses and ask the right questions when needed.
I like the brief case version as I'm looking at transporting the "parts" in the top half of a large Back pack (or lower half to top) to Hike with. I understand what you say about the compromises, however need to learn quite a bit in order to make the right decisions.
I really don't know what else to say...I guess a 2" focuser would be preferable for lower Mags? I just figure if I could better understand how the parts all work with respect to measurements and alignments...that might be a good place to start. I think the lack of lower altitude is not much of a big deal for what you end up with.
I'll go check those links and start learning...thanks again
