This has to be the most expensive skywatcher ever. Not a classic, but I am sure this listing will be
Or you could buy this one for a little bit more
which one would you buy?
Looks like that's what the Skywatcher retails for.

Some are good, some are bad, I think it is true to say that quality was more variable with the D8 than with Celestrons. From what I've read Criterion did not match the secondaries to the corrector unlike Celestron who refined the figure of the secondary to compensate for any irregularity in the corrector and this may account for the greater variability but I don't know for sure.
They also seem to benefit from fettling, getting the corrector and secondary centred and the primary squared up - see for example, Andy Taylor's post in Cats and Casses, "Dynamax 8 - from a pigs ear to a silken purse... " And cool down time can be longer than an orange tube.
Mine seems to be a good one (maybe because I've refrained from touching the optics - a little bit of knowledge is a dangerous thing) and has virtually none of the usual SCT image shift, unlike my orange tube C5. But I think in a blind testing you would spot which was a D8 and which was a Zeiss!
Interesting difference in production numbers, serial numbers would suggest Celestron produced upwards of 25,000 C8s by the end of 1981 whereas Criterion produced either around 3,600 or 4,600 over the same period, depending on whether they started numbering from 0001 or 1000.

I notice that the Unitron and 10" reflector deal appears to include a bullhorn; perhaps a little something to draw attention to one's self and scope during public events...
Hmmmm... the mention of a "cult-like following" that the 6" Dynascope has attained tells me that the seller might have been reading this forum at one time, wouldn't you say?
That next-to-last listing has been on CL several times in past months, and is a reasonably-priced, effective and beautiful instrument; surprised that one of our Florida members hasn't given it a good home yet.
I do love to see people's pets who wander into frame, such as the cute and furry kittycat who's quizzically looking up at the scope in the final listing!
