Where did you get your eye cups from? they look sweet!

I got the eyecups and caps at the very fast and friendly http://www.agenaastro.com/

So here's what I did with my Meade 24mm 5000 UWA. When I got it, it had the eye cup off..... much lighter. I then re-added the eye cup and tried it that way. I like the Meade series 5000 24mm UWA way better with the eye cup right off. The eyepiece is much lighter at 1.6 Lbs....with the eye cup on it is close to 2 Lbs.
Also, with the eye cup in place, it feels too bulky and weird....so I keep it off all the time now...much better! :grin:

Would like to know if the diet 24/68 will increase the "window look" for eye-glass users. I'm using the 26/60 on my day-light bino-combo http://www.cloudynig...5/o/all/fpart/1 and would like to know if the 24/68 will increase the window look - the ES24/68 will take "ages" to arrive to Europe and will be more expensive...

Thanks

The revival of this thread has made me think seriously about putting my own Meade 5K SWA 24mm on a diet. The advantages for me would be (1) more room in the eyepiece case, (2) lighter eyepiece, (3) will fit better in my Dark Sky Apparel vest for grab-n-go, (4) smaller size and better balance for my small grab-n-go scopes. Disadvantages would be (1) need to set aside time to de-shroud the eyepiece, (2) need to construct and attach a felt guard for the rim, (3) and I kinda liked the look of the eyepiece before going on a diet.

Magnitude7,

Exactly which size eyecups and caps from Agena Astro will fit the slimmed-down Meade 5k SWA 24mm eyepieces?

The barrel is 48mm. Not sure where I got my cap, but it fits tight. I cut the ridges from the inside of the cap to make it easier to place on the eyepiece.

Steve,

I have a box full of various size caps and several sizes of eyecups on my eyepieces. Probably the best thing to do is to just experiment with what I have after I put the Meade on a diet.

Sorry to come back to my previous post but I have to decide if I go for a pair of Meade 5000 24/68.
The useful eye-relief of the 24/68, after passing through diet, is similar or better then the one on 26/60 without diet?
Thanks.

David, that is hard to say with certainty unless the two models were compared directly for that function. However, the 26mm Meade 5000 Plossl was always easier at least for me to use. This is since a simpler optical design than the more advanced one in the 5000 24mm SWA. Please note that Plossls and related are the best type eyepieces in general for binoviewer use. That is what optical legend Paul Rini told me several times over the years. If you can do it why not try the new Meade HD-60, Celestron X-Cell LX, or Astro-Tech 25mm Paradigm. They are all with better eye relief than the earlier 5000 models you are asking about. Good luck! :D

Starpal,
Thank you for your reply. I already tested the Meade HD-60 and the probably equivalent of the AT25 that is the Teleskop Service HR25. The Meade 26/60 have a flatter field at lower magnifications with my combo. The 26/60 result on a wider FOV and even flatter then TV Panoptic 24 - I have a pair that I will sell since the eye-relief is not enough for me - I use eye-glasses. However the Pano 24 seem to produce a bit more resolution at higher magnifications. So I wonder if with the MEADE 24/68 I could have a more "window" view than with the 26/60 and also gain on resolution at high powers. By the way, in terms of image quality and "window" view I seem to prefer the combo with the Baader Mark5 and the pair of 26/60 than a TV Nagler type4 22/82 - 2 eyes seem to view better, at least for day-light use, but I still have to do some resolution tests.
So, if someone still have both the Meade 26/60 and the 24/68 I would appreciate inputs on the eye-relief.

I have a pair of the AT Paradigm 12mm that I like very much for binoviewing planets and the Moon through my 8" and 10" Dobs, which require at least a 1.9x OCA, yielding the equivalent of about a 6.3mm pair. I don't usually binoview any objects other than the planets and Moon, so I don't need low-power wide-field views.

I performed the operation on my Meade 5K SWA 24mm a few weeks ago. The most difficult part was ripping the shroud off the barrel. Someone really should have explained exactly how they did this. What worked for me was to raise the shroud to its full height, and carefully reach a finger inside to hook the edge, then gingerly but forcely pull upwards while firmly holding the lower part of the barrel with my other hand. I did this several times at different positions around the shroud until it finally began to come up and tear off, all the while being careful not to touch the eye lens.

The shroud ripped a bit at a few areas, but that was OK. I wasn't about to put it back on. After cleaning off all the pieces of the shroud, I carefully wiped off the barrel and top rim of the eyepiece with Kleenex to remove all the oil.

Maybe a mohel would be good at doing this? :grin:

I haven't added a felt ring to the top of the eyepiece. I'm OK with the eye relief, even when wearing my eyeglasses. I always sit when observing, so my head isn't bobbing around. I can keep my glasses from being scratched on the rim. IMO, this is not a big deal. I don't think I'll bother with the felt.

Instead of bothering with a felt ring for the slimmed-down Meade 24mm, I will order an eyeguard and cap for the top, either from ScopeStuff or Agena. I'll probably wait and see if I have any other eyepieces which still need eyeguards.

Anyone know which one will fit? If not, I can just measure the barrel diameter and order that way.

I still have a Meade 5k UWA 6.7mm eyepiece that has not been "cut." However, I don't think I will bother deshrouding it. The shroud on that eyepiece actually serves a usual purpose and does not increase it's girth to the point of getting in the way.

David, good luck getting the answer to that question. I can add that when I used an OCA lens under the binoview the Meade 5000 26mm 5-element Plossl was made sharp across most the FOV using an f/5.8 Newtonian.

I've got a pair of the 5000 20mm SWA and will also be leaving the outer shroud parts on them. They are compact enough and quite attractive looking in the binoview.

Right, it doesn't really make sense to do something just because you can do it.

OK I know this is an odd question, especially seeing as this thread is over three years old, but....

 

Any up dates ????

 

Good or bad, did it effect resale values?

 

I don't see many people doing this any more.

Considering that the shroud/eyecup removal turned a good eyepiece into a great one, I have no idea why someone would want to sell it.  I did 3 removals and all 3 (sorta) svelte EPs get regular use yet are still reasonable ballast to keep my EP case standing upright.

 

In any case, the optics continue to be available in another form factor from ES so the resale market for these EPs is rather narrow so why not hack them down to size? It'll make you feel good!

I agree!

 

I am well known for selling eyepieces...but this one below isn't going anywhere !!! (34mm Meade 5000 SWA).
