Ouch , the Dynamax's were a design and manufacture of the C8 Celestron and Celestron sued them for that ??? welcome to America.
Because of this most of the money that should have gone into R&D went into Lawyers ,,, shame .
Apart from that rubbish the Criterion's were quite good , their engineering ,,, eg.
Tripods , mounts were way better than Celestron and Meade at the time , optics well ? they suffered because of the legal battles happening ,, a real shame
.
Price ?
with case , tripod and OTA in good condition I would say Max of 1.5k here but as said in the USA this would be worth much more , I would love to have one .
Classic Telescope .
ps. thanks for the thread ,
