I received two eyepieces today. Both are Meade 4000 DS Super Plossle. One is a 9.7mm, the other is a 26mm. The 26mm appears to have had its rubber eyecup torn off. Is there any way to replace this piece or is it lost forever?

I have those same eyepieces.  I don't know whether Meade sells replacement rubber eyeguards, but Orion does:  http://www.telescope...pieces/e/70.uts

 

There are generic rubber eyecups (similar to the Meade ones) that could work:  https://www.ebay.com...rubber&_sacat=0

I also saw a trick somewhere a few days ago where you use bicycle inner tube, cut and rolled back on itself, as an eye cup. Looked excellent.

I'm on my phone and can't give you the web site. I'll post it when I get home. The worst people to ask is Meade customer service.

I didn't even call them. I've already seen how poor their product support can be.

Well darn it all. Got some from Telescope Warehouse (http://shop.telescop...3 fits Meade ep)

a couple months ago, but they seem to be out of them. Sorry.

Yup, been doing that for years.

I keep a variety of bike tube in the shop for just that purpose !

Works great on both EP's & bino's:

I MAY have located a set of replacement eyecups. They claim to fit Meade eyepieces. It doesn't specify if they are replacements or add-ons, but I ordered them none the less. They should be here in a few days. I'll update you guys then.

So the eyecups arrived frim Amazon yesterday. They are actually successful replacements. The original eyecups would fold down out of the way, these will not. They're a little stiffer than the originals, but with as much light pollution as we have around here, I can't imagune I wouldn't use them. Here's the link in case anyone else needs them:

Thanks for the photo.. I have seen the recommendations of using a bicycle inner tube but never picked up on the fact that you had to double them back over themselves, now it all makes sense... I'm eager to get back home to my stock of bicycle tubes and give it a try.

 

I stock bicycle inner tubes because between my wife and I, we have 15 bicycles...

You bet Jon, After you cut the tube pieces, give them a quick dish-soap wash in the sink to remove the talc that is always inside the tubes. Also in addition to the small diameter tubes you obviously have alot of, you might pick up a 'baloon-tire size (ie 2.75") for large diameter EP's.  You will always have eyecups for any application.  More or less a necessity for us DIY-EP nuts... :)

 

BTW your garage looks about like mine, too many bikes and too much astro stuff :)  We were down to 4 bikes after the kids all left home, then came the grandkids and we are back up to countless bikes.  Of course the telescopes just seem to multiply on their own somehow, I spend a few weeks working in the shop and somehow another one appears :)

More news. I discovered today that, at least some, Celestron eyepieces use the same eyecups as the Meade Series 4000 eyepieces do. That may or may not help, but its more info to use.

Tsk, tsk.

There have been a lot of threads with pictures here on CN over the years.

Be sure to use the width of inner tube equal to the O.D. of the eyepiece, i.e. use a 26x1.75 tube for an eyepiece with a 1.75" O.D.

Cut the ends of the small tube section as straight as you can so that when it is folded over the ends meet squarely.

And if you err in the length, you can always trim it or cut another.  One tube is good for a LOT of eyepieces.
