[ATM] building a collapsible DOB

[RP <rp@suttonsonline.us>]

Thanks to everyone for their ideas and concerns - I will be looking over 
all the suggestions. FWIW, my scope's current "truss" setup is 4 
straight aluminum poles, no actual trusses. So far it has held 
collimation well and even supports a 40mm Paragon and 2" barlow 
combination with minimal flexure (at least not enough to through off the 
collimation in any noticeable way). I was originally hopeful that I 
could find  collapsible poles that I could sub for the straight poles.

Thanks again -

RP
