Not too sure Simon but I think it must be a doublet - see here for the specs:
http://www.skywatchertelescope.net/s...1=1&class2=101
It has FPL-53 Schott glass lenses, same style "rotating ring" for the focuser unit, same L-shaped tripod/GEM mount and definitely the bodyworks is an exact replica - except the TMB claims to be a triplet (and it may well be) with a slight difference in focal length of 504mm instead of 500mm
I know that the SW Equinox was made by Long Pern for Synta because when my OTA slipped off my mount (the dovetail lock screws loosened somehow) and the focuser's knobs and spindle/shaft broke, I tried to get a replacement crayford focuser unit from SW but was told that it's not available as spares because "we did not manufacture this ourselves" and a little birdie informed me of Long Pern and after failing to convince Andrew's to get a replacement for me I called the factory direct and because my order is just one small measly part off a unit, I got knocked back.
Because of this I started a bit of research and noticed that there are lots of OEM-labelled Long Perns available including WO who probably got theirs from there too - check the WO 66mm and look at the 66mm Equinox on SW's site - I believe I read on Andrews website some suggestion that the Long Perns 110mm OTA is "similar" to WOs and they do look alike
BTW the Equinox range is also sold by Orion as their EON range
I can from my experience tell you that the 80mm OTA is tough as nails and very well built - the collimation was still A+OK after the fall!!
Well the mass-production of these "toys" that we play with also allows the manufacturers to sell their wares to those who can order volumes and stick their own brand on them - that's economies of scale for you!
Cheers
Bill
