Frankly, this is what Ive heard also. Its not the optics per se in fact
our lx200 has a nice primary and when you lock down the priamry carefully so as to keep things oin axis, then collimate, the scope is quite crisp.... but with poor contrast. Mechanically the scope is a dog. jerry ====================================== Hi Jerry, Well, I'll buy that. I would assume that there shouldn't be differences between the optical quality, or the time spent to match optics between an 8" LX-200-16"-LX-200, and one would also think that closer attention to detail and quality would be spent on thier flagship SCT scope. No doubt these same maladies also affect the Celestron C-14 also, in that countless owners try to devise ways of getting away from mirror flop, as the mirror flop definitely has an effect on GOTO Pointing, CCD Imaging, and maintaining a high degree of collimation which as we all know is paramount to achieving top performance from any SCT. Many C-14 owners also have resorted to OTA internal flocking, and I've even heard mentioned the flocking of the Baffle Tubes as well on SCTs. Pehaps this is mod also needs to be done on the Meades to enhance performance? Though, for the price of what these top of the heap SCT's cost, maybe areas like this should have a bit more sophistication implemented into them like a better Primary Baffle-Mirror Support. I imagine on an 8" SCT, the primary mirror is not so heavy-bulky to be that great of an issue, but on 14"-16" SCTs, even though these mirrors are not full thickness, and are cast in a roughly concave state first before grinding-figuring-polishing, they still must weigh a substantial amount.
