Being in the US, you might also investigate mounting a green laser sight to get you quickly in the neighborhood and to save your neck and back. I like the compactness of the Rigel QuikFinder over the Telrad for shorter scopes. A 9x50 or larger RACI finder scope would indeed be helpful given the 2000mm focal length of your scope.

Latest from Dave Bush on CN: *** Reply from ES.. “We will refund the purchase amount including shipping costs completely. Additionally we ask you to destroy and dispose the eyepiece afterwards. The effort to send it back is unfortunately too high. We will send you a confirmation about the credit note by email promptly and ask you to excuse the circumstances. Explore Scientific will inform you if there are any news” I suspected they'd realize reverse importing them back into the EU would be a complete taxation/tariffs/shipping costs quagmire. Literally nothing I've cross imported into the US from Canada, Australia, or the EU has ever had any sort of sales tax or import tariff applied to it. I'm sure the reverse would not be true to any of these countries from the US, though, even for a return.

You're getting a 30mm ES-82 in addition to the 28mm WO/Nirvana 82 degree eyepiece? Did you mean 18mm ES-82 since that is what is shown in your photos?

Here's an explanation from Dave Bush on CN about the disappearance: Well, this is interesting. I just received an email from ES stating the following... Recall After receiving some negative feedback on the imaging performance of the new LER 82°, we unfortunately noticed serious problems with the imaging performance. Extensive random checks of the batch confirmed this suspicion. For this reason we ask you to send all eyepieces of the 82° LER series back to us. You will receive a credit note immediately. Now, I've not had a chance to test my 8.5mm but I'm hoping to give it a shot tonight. Depending on how it performs I may take advantage of their recall. I wonder if they will be reimbursing all import duties in both directions as well as shipping charges. Do they then apply to the respective governments for reimbursement of the duties collected?

I was able to retrieve the original webpages via Google caching, but you can't put the eyepieces in your shopping cart from the defunct pages. Looks like Dave Bush will be the sole owner of one of these eyepieces for a while now.

You was meant in the collective, all of Europe, you (as in y'all). It appears Dave Bush was just curious enough to buy one. I'm pretty well covered at those focal lengths by Morpheus, Delos, XW, XL, and SW Zoom eyepieces that I have zero curiosity about them. I'm still waiting for the 22mm-25mm ES-92 to be announced. I'm more than ready to replace my 22mm NT4.

Which begs the question why no one in Europe has bought one since they're local to y'all. I would have thought you'd beat us Yankees to it.

Extensive CloudyNights thread on them.

Well, this SW HF 7E2 zoom looks to be identical to the ubiquitous 7.2-21.5mm zooms such as the Skywatcher Hyperflex 7E1, Lunt, Orion Zooom!, Opticstar XL, Omegon Cronus/Premium, Orbinar HQ FMC, Solomark Planetary, and TS HR Planetary differing only in focal length bounds. I would imagine the two utilize very similar lens designs and so probably perform similarly, differing only in magnification.

Given my strong astigmatism and the 26T5's lack of usable eye relief, I'll have to wait on an ES-92 to come out in that range.

The 30mm APM UFF views really similarly to the Delos. I highly recommend it. The 24mm APM UFF not so similarly. It's nice, but a step below.

Those are the binoviewer specific eyepieces that yield an artificial 3D effect.

I noticed the same thing. I'm guessing that spreading out the red tint over a larger part of my retina decreased the perceived saturation.

My main Dob has no issues with the 34oz 30mm ES-82 or the 31oz 40mm Meade 5000 SWA (after decloaking both), but it tends to nose dive below 35 degrees or so with the 41oz 17mm ES-92, so I had to add some counterweight to the back. I had to add more counterweight to my DSV-2B above about 65 degrees with my AT72ED to keep it from flipping backward.

If you can swing the weight, they are terrific. Viewing through them is super easy and the views are sharp and contrasty to the edge.

I ended up replacing my 17mm NT4 with the 17mm ES-92. Likewise for the 12mm NT4. I don't think I could get the NAV-HWs to work with eyeglasses. Has anyone tried them with eyeglasses?

Did you add a parfocalizing ring or some such to the chrome barrel?

I think if you use two ordinary star diagonals at 90 degrees to each other and look into the eyepiece from the side rather than back of the scope, you'll also get an upright and non-reversed image. This presumes sufficient backfocus, but if the scope supports binoviewers natively, this shouldn't be an issue.

And a more recent follow-on article by Bill P. about the Baader Broadband Hardened Silver (BBHS) diagonal versus a dielectric and prism diagonal.

Their caps appear to be very similar to those from StockCap. Search for vinyl caps OR plugs wholesale to look for other manufacturers.

I keep a separate toolbox full of non-eyepiece accessories such as collimation tools, camera adapters, a filter wallet, rarely used accessories, laser sight batteries and charger, boxed 1.25" correct image diagonals, etc. I keep my Telrads in a foam padded box because they're so large, but my QuikFinder is small enough it lives in a low cost, foam padded eyepiece case for miscellaneous eyepieces like my reticle eyepieces.

@emadmoussa, My large/long eyepiece case is a Doskocil XL which is long since discontinued. The Pelican 1600 is the most similar currently available case. I recently bought this case at Sam's Club for my retired or seldom used large/long eyepieces and barlows. It is no where near as nice as the Doskocil or Pelican because the foam is not as dense and it does not have a base layer of solid protective foam at the bottom. It is much cheaper than either premium case, though. As you might have guessed, I like my eyepiece standing up on end when possible. The case has a much smaller footprint as a result than having the eyepieces lying on their sides.

I picture the app no longer being supported 5 years down the road and not being compatible with the newer OS releases. This then forces you to avoid upgrading your tablet's OS to maintain backward compatibility with it. I've run into this issue repeatedly with various PC peripherals. It sort of "encourages" you to buy newer peripherals, or in this case, mounts. As a result, I've still got 98SE and XP systems still tucked away around the house.

The 24mm APM UFF is similar in design and quite nice. The 30mm APM UFF is an entirely different design and evicted my venerable 27mm Panoptic from my A-team case. Let us know your thoughts on the 18mm. I'm mostly curious if it has enough eye relief to use with eyeglasses.

I'll second the recommendation for https://eyepiececaps.com/. I ordered their $20 eyepiece cap and plug bundle. It arrived quickly and all the various bits fit perfectly.
