I recently completed this portable scope as an experiment. Loosening the knurled clamp rings on the four tubes lets the scope collapse down to a 28" x 12.5" x 10" package for storage or transport. Fully extended, the height is 45" to the top of the spider,perfect for seated viewing. The tubes are very rigid when the clamp rings are tight and the sliding action is nice and smooth with rings loosened.
The altitude trunions are lined around the outside with industrial strength velcro, like StarMaster telescopes, and they ride easily and smoothly on Teflon bearing pads. Each trunion is independently adjustable for OTA balance by loosening the two knurled nuts on the outside face.
It has a very nice Edmund 8", F5 mirror, no scratches or sleeks, and presents a bright, high contrast image. The mirror is also polished on the outside edge as well as the bottom. It rests on three silicon pads but is not glued down. It's held in place by three wooden pegs around the outside perimeter and nylon disks on top of the pegs keeps the mirror from falling out. These nylon disks can be rotated 180 degrees to allow the mirror to lift out.
The secondary is 1.5", which represents a central obstruction of under 19%. The focuser is a 2" helical Crayford style. Unlike some others like this you may have seen, this focuser has ball bearings all the way around. The single bearing on top rides in a spring loaded carriage so the focuser tube moves very easily and smoothly with no binding.
This is a very unique, nice performing scope that will present you with contrasty, wide field views and will get lots of attention at star parties.
