Don's Spring Counterbalance Telescope

Don's Spring Counterbalance Telescope

Don P.
This is my string counterbalance scope based on Tom Krajci's counterbalance concept. The scope is designed to fit a travel bag and is designed around my existing optics. The scope goes about 20 degrees past zenith. The spring acts as a counterbalance on both sides of zenith. The disadvantage of the counterbalance is that the scope is tippy when viewing near the horizon. Note that I just changed this scope to a stacked string telescope design. <http://dbpeckham.com/Telescope/String/String8.htm> #amateur_telescope_making #ATM #counterbalance #dobsonian #Don_Peckham #krajci #newtonian #spring #telescope
