Meade s4000 QX Wide angles

[PaulM (Paul)]

Hello,
It's interesting to find my "quick review" of the Meade QX eyepiece quoted here!! Looks like you found me WAY before I found this Forum!!
Good to see my efforts to keep my web site up to date are worth while

and an owners observations @ f5 taken from this observint log

Quick review of the Meade 2-inch QX eyepiece, 26mm
Near the centre of the field of view it's very nice, but towards the edges the stars are streaks and never come to focus. I suspect this eyepiece is not suitable for fast f5 optics. I hope this eyepiece will perform better in my 10-inch f10 LX200 ! The wide field of view (70* apparent FOV) is very nice. When compared to a 26mm plossl, the Meade QX gave an extra 40% field of view. Of course, when stars are streaks towards the edges, the extra field is kind of useless.
** Update: this eyepiece performs better with the f10 LX200 !!



Cheers,
Paul.

It will reduce the astigmatism and various other aberrations caused by the eyepiece's inability to field the wider light cone. Just be aware that it will not reduce coma from the mirror (which, anyway, is not caused by the eyepiece).
But the 26mm QX is a 2" eyepiece, and the LB scopes can't handle most 2" barlows, as the barlows need too much infocusing.
So you may not be using a barlow on that eyepiece after all.

Given that these QX eyepieces are packaged by Meade with the Lightbridges, do you think that a retailer would provide credit on the eyepiece if you wanted to replace it in the package?

No harm in trying but I doubt it.

Yes, a long shot I thought. Probably wouldn't get much of a credit but not sure how easily you'd sell one S/H, there doesn't seem like there is much demand for them

Just adding my five bobs worth (don't know how old this thread is) I got the QX with my 112" LB and the first time I tried it, I was not impressed because of fuzziness around edges -- HOWEVER when I tried it a few days later on some large clusters, I was absolutely blown away with the view - I could not even see any noticeable fuzziness. I think the first time I tried it, the mirror had not come down to temperature, so air currents stuffed it up.
I now call the QX my "Cluster Buster" and use it all the time - it is almost my favourite as I just love those open clusters.
