The odds are against you.
What would be interesting. If you buy one and later pay for an optical bench test proper.
Edit: The odds are stacked against you that you get something better than diffraction limited.
I think that would be good enough. Testing would be interesting. A scope manufacturing place/optical shop is being considered in the little town west of here, Magdalena. I may be able to just do it there myself someday.
But a bad sample seems highly unlikely. Celestron's been making SCT's for quite a while and they are a very significant %-age of their market presence.
Sounds right. My 1979 C8 is really good, the Super C8 is not bad, and I've got no complaints about the 8 Edge so far. Maybe I have just been more sensitive to bad news about C11s, since I have been thinking about them.
I have had a total of 3 Celestron 11" scopes.
The first was a black tube from the late 80's or early 90's. It had horrible optics, I think the corrector plate had been replaced by some do-it-yourselfer. The edge of the glass was not precisely ground round. it was all chipped. This is not the usual Celestron style.
The second was a very nice carbon fiber model. It did have very nice optics.
The third is the HD edge that I currently own. It is a very fine scope giving the fact it is a SCT with all their shortcoming AND their good points.
I doubt you will be disappointed by an 11" Edge HD performance.
Keeping in mind the atmosphere is ALWAYS the limiting factor.
I live in the desert, but it's getting harder to prove it. Lot's of high thin clouds these days (months, years). And when it is nice and clear there's dust in the air. Plus my eyes will be getting older, so maybe I won't even notice. I've been pretty happy with the Cats I've had. I like wide field stuff a little more, but I just got my HyperStar stuff goin on my C8 over the weekend and was able to get all of M31 in the frame on a ASI1600 (APS-C size), so I think the 11 will be OK in that respect too. Sounds good.
I don't think the odd are against you I believe you have a good bet of getting a good 11 sct , I would say about a 80 to 85 percent chance on getting a good one. Even if by chance you get a lemon just send it back for a refund.
Boy, you guys must all work for the credit card company. The only trouble I've had with a new scope was an Evolution C6, but that was the mount. Astronomics was all over it and got Celestron to contacting me right away. There was a new one in the mail the next day.
I'll wait until after work and probably go for it. Just this weekend I was thinking, "It sure is nice to be finished buying scopes and adapters and fans and bolts and filters and cases and..."
Thanks for the inputs!
