Looks like a cloud attracter to me!

Hmmmm, it just so happens that I also recently bought a 2" Orion Imaging Skyglow filter for visual use. It'll be fun seeing how well it works with this eyepiece.

The Meade UWA 24mm is supposed to have a twist-up eyecup, but mine will not twist-up. When I try to twist it up, the lower part of the barrel starts to unscrew. This isn't a big deal to me, since I intend on taking that bulky shroud off anyway.

Anyone else have one with this problem?

Mike

Never mind, problem solved. I just kept tightening the lower barrel of the eyepiece and then trying to twist-up the eyecup, several times, until finally the eyecup came up. No biggie.

Called today and after some rattling he said it shipped Wednesday. Hoping the eyepiece isn't too heavy for my dob once the shroud is removed. Anyone try the diagonal yet?

I just got a look through the eyepiece and diagonal, and I'm pretty impressed! Really nice eyepiece (yes, I had the same difficulty with the eyecup shroud movement, but got it working after a bit trying). I compared it to my 20mm Explore Scientific 100 degree (the closest thing I had)..(besides my Orion 26mm Q70...no contest there, duh) The Meade 24mm UWA was excellent in every way and snapped into focus, and the edge looked very good. Color and contrast was wonderful.

The diagonal surprised me. I compared it to my Williams Optics 2" Dieletric, and the Meade gave me a tiny bit more light in that very faint stars were just a bit easier to see in the Meade. The faint stars I chose as test subjects looked somewhat dull in the Williams Optics diagonal, but in the Meade diagonal those same stars had more sparkle to them and appeared a tiny bit brighter. I didn't expect that, but I am very pleased.

We had snow and ice on the ground, and temps in the teens last night. I need to walk the scope around the side of the building, so no first light yet. I don't want to chance a slip while carrying the equipment. Winter astronomy is not good for me.

I got just the diagonal; to match my 10"ACF; I didn't need another EP of this type; especially a one off. I also got the 1.25 RGBL filter set. :-)

Thanks for the report on the diagonal. I read the blue anodizing causes internal reflections. Maybe they blackened the inside.

Today I deshrouded my new Meade UWA 24mm. Makes for a lighter, narrower, less bulky eyepiece.

But I do like having an eyecup to help center my eye at the best distance from the eye lens, and to help shield from ambient glare. Rather than try to find an eyecup to fit from a vendor, I cannibalized the top of the Meade eyecup.

I cut off the top section of the eyecup where it becomes thin. To do this, first I cut a slit with an X-acto knife. Then I began cutting at this slit with ordinary scissors, working my way around to cut off this thin, upper section of the eyecup. I turned this rubber ring inside out, and fit it on top of the eyepiece.

Now I have a nice, eyecup which positions and shields my eye just right. And the original Meade eyecap fits snugly on top of the eyecup.

IMO, this slimmed down eyecup is much better than the original shroud. I wish I had thought to do this with my other three Meade 5K eyepieces. I have a SWA 24mm and a bino pair of UWA 6.7mm. I was able to find good replacement eyecups for all three, but now I wonder if I could have cut out decent eyecups for them from those bulky shrouds.

Mike

Eyepiece with resized eyecup and original eyecap in place. A snug fit!

Old shroud with resized eyecup removed. This is what is left over.

That looks great Mike,and you get to keep the original cap as well. Did you turn the rubber ring inside out just for cosmetic reasons or for a better fit? I think I'll try this with my 30mm since the shroud is just sitting around taking up space now.

Eric,

I tried it both ways. The rubber ring fits better on the eyepiece and feels better against my eye when I reverse the ring.

Unfortunately, I threw away the shrouds for my other Meade 5k eyepieces.

You can create an eye cup from a bicycle inner tube by buying a tube with the width (not diameter) of your eyepiece (an eyepiece that large would definitely require a mountain bike inner tube).
You cut out a 2-3" section of inner tube, clean it thoroughly, and stretch it over the eyepiece and bull it down a bit. Then, fold the inner tube segment over to create a folded lip at the top and so the outer part of the tube segment is pulled down over the inner part.
You can adjust the height to whatever you require, and one inner tube will make a hundred eyecups. If it wears out or deteriorates, just make another.
Look at this example: here

The cannibalized, inside-out ring from the Meade shroud worked very well. I can't imagine any improvement on that.

Sure, but you mentioned you couldn't do it for the others because you had already discarded the eyecups.
