Re: Meade UWA 24mm & 2" Dialectric Diagonal: $159 new [Re: bob midiri]
      #5666728 - 02/07/13 09:52 AM

We had a break in the weather for a couple of hours last night and I had an opportunity to test this eyepiece on my Lightbridge 16. It's a heavy eyepiece, but I still could use it would adding any counterweights to my scope, though just barely. At low altitudes I added a 2.5 pound bean-bag weight to the lower end of my scope to improve the ballance. Although quite large, the eyepiece looked pretty good on the Lightbridge's focuser. The wonky eyeshield worked quite well, so at least for now I'm going to leave it alone. The field of view was wonderful, though there was quite a bit of coma at the edge of the field. That wasn't too surprising and for me it really didn't detract from the view. I'm curious to see how this eyepiece performs on my AR-6. Overall I'm very pleased with this addition to my toolbox.

Yep, my EP has a huge ding in it as well. I'll post a pic tonight.

These are seconds. People, don't fool yourself otherwise.

I don't think so. The box mine came in has a Meade label on it that states: "PROMO 2" DIAGONAL AND 24MM UWA KIT" and has the part number of: 07681.

There's also a UPC: 709942002300

Not "seconds".

Agreed. Mine do not have a mark on them, mint.

Both my eyepiece and diagonal were perfect in every way. I can't really see them being 'seconds'...

Oh my goodness. I had a chance this evening to try out my new star diagonal and eyepiece on my AR-6. The blue anodized diagonal looks sharp on my Moonlite focuser. Better than that, the view was absolutely amazing! M35 was simply stunning and the wide field around M42 was wonderful. I'm ready for Comet ISON!

I guess then that Meade quality control was having a bad day....

Shane,

If the rest of the eyepiece is OK, you could just take the shroud off. I prefer my Meade UWA's naked.

That nick just increases the odds these are OEM products that were destined for scopes. OEM packaging is usually minimal and the boxes probably get moved around a lot. If they were clearing out some OEM stuff, then there is a distinct possibility these are Jing Hua eyepieces instead of Meade's new manufacturer.
As for the nick, no worry. Look up the thread here on CN about putting Series 5000 eyepieces on a diet. That roll-up eyecup weighs a ton. The eyepiece is smaller and lighter without it. There was even a recent thread on creating a new eyecup from the old one.

If these are the Jing Hua ones, I'd consider keeping it as long as there's no other damage. Those eyepieces really do put up some good views........

Anybody know how to take off some weight from the Meade 24mm. It's close to 2#

Yes. Take off the shroud. This thread explains how to do it:

How To Put a Meade 5000 on a Diet!

Save the shroud, because you can cut off the upper ring to make a nice eyecup for the eyepiece. Look farther up in the thread you are in now for pictures and text explaining how to do that.

My point was that it would do Meade a dis-service to send out "seconds" as promotional items. But, obviously, there are/were some quality control issues.

I just noticed the visual back extension tube that came with the diagonal is composed of two pieces, one of which is a 1 inch extension. Nifty!

Which might make it usable on LX90s that have less clearance between scope and base.
Also, using it in the shorter configuration might prevent the lengthening of scope focal length that occurs with increasing back focus distance, i.e. give a slightly wider field of view.

Yes, that is how I use mine, with just part of the OTA, otherwise it's too long and will hit the base of my scope. Also hear that this configuration turns my 2000mm scope to about 2200 and f/13?

I just noticed that myself. I had to turn the 2" extension pretty firmly to remove it. That reduces the accessory train by 30mm.

Would removing this extension be enough to prevent appreciable spherical aberration and reduction in clear aperture? Would it be enough to satisfy the Cat Cops here on CN? Hmm... Probably not.

Yep, that short 2" visual back has come in real handy. It's a tad shorter tn the one that I've been using from OPT. I also repaced the bulky eyeshield on my eyepiece with one of my homemade eyeshields. This reduced the weight by 20%. I'll post pics when I get a chance.

Looks like it was dropped. I'd call , ask for a replacem, and return it. Otherwise you will never be satisfied.
