I am looking for an 8" F/4 Newtonian for imaging use that can survive a bumpy car drive over the hills without the collimation going totally out of whack.
(Yes, I will try to pad it well) Also the weight of the OTA by itself should be on the lighter side, maybe less than 18 lbs? Finally, focuser and secondary large enough for APS-C sensor. (might require 2.5" focuser?)
The only ones which I have heard are "low maintenance" are:
TS ONTC carbon fiber w/ 3" focuser- weight approx 15 lbs
Vixen R200SS - weight approx 15 lbs
