For use in my "supercharged" Mark V with the APM 152ED or the Celestron Omni XLT 150R, I use the following pairs:

  • 35mm Orion Ultrascopic/Celestron Ultima/Parks Gold (I have one of each, can't tell a difference between them)
  • 32mm TPO plossls (will probably sell as they provide a narrower FOV as compared to the 35mm above and the 25mm/24mm below)
  • 25mm Meade HD-60
  • 24mm APM UFF
  • 18mm Meade 5000 UWA
  • 14mm Meade 5000 UWA

I also use the 1.25x and 2.6x GPCs

 

The 25mm and 24mm are a tough call for me... the 24mm provides a wider FOV, but the 25mm seems like it has better transmission and might be a tad bit more comfortable to use. Do I even need the 25/24mm eyepieces? Not quite sure at this point since they're between the 35mm and 18mm.

 

I really like the Meade UWAs, and the Ultrascopic/clones. 

 

I'm looking for something with a bit more mag, mainly to prevent swapping out GPCs, and am thinking either the Meade 5000 series 8.8mm or 5.5mm since I already have one of each. I have the 6.7mm and the 4.7mm as well, but I think I like the mag and spread between the 8.8mm and the 5.5mm a bit better.

 

Anyone out there using these pairs and care to comment? Single use thru the BV they seem to do fine.

 

Thanks!

I’m still a beginner in binoviewing, though I’ve owned my Orion binoviewer for a few years (took a break from astronomy...), but I’m tickled pink that I have it now that I’m back and saw the Orion Nebula through both eyes for the first time.

 

I only have 3 pairs of eyepieces:

 

12.5mm & 20mm Long Perng (sterling) plossls

17mm Orion plossls

 

 

I had misplaced one of the two 20mm sterling plossls years ago, and when I couldn’t find it after getting back into astronomy, I figured I had mid-remembered that I bought a second one for binoviewing and was lamenting their current unavailability, but I found it in the back of a cabinet the other night and I’m so happy.

 

The Sterling and plossls are great eyepieces for any price, but especially at the prices they used to go for and the 20mm had really nice eye relief for binoviewing when the 2x OCS is used. They have great contrast and internal reflection control. The 55 degree AFOV appears much wider when both eyes are in use.

 

The 12.5mm pair was great on Mars in my 6” reflector when I screwed the 2x OCS into the body of my shorty Barlow lens in order to bring it farther away from the binoviewer and increase the magnification even further.

The 17mm Orion plossls are meh... I really resent that their field stops aren’t sharp, and contrast is clearly not up to par with the sterling plossls. Nor is internal reflection control.

I have a 1.6x OCS on the way and am very excited to have an even wider Field of view for DSOs and the Milky Way in the summer.

 

I’m going to keep an eye on this thread as I want to expand my binoviewing options.

 

I have one Explore Scientific UWA 14mm and I’m seriously thinking about getting a second one.

I wonder if one of the less expensive non-argon purged generic versions would be identical enough to work as a pair with the one I bought years ago?

 

This binoviewing thing is really addictive!

I've had a binoviewer for years, and seldom took it out due to lack of a wider FOV; I preferred either the low power/wide FOV that big binoculars offered, or the zoomed in view of the single eyepieces that I have.

 

Then, for whatever reason, I decided to buy a BV with a bigger clear aperture, and the 25mm Meade HD-60s, and I was immediately asking myself why I hadn't done this before. Going back to single eye viewing SUCKS big time now.

 

I'm holding on to my 2" Meade 5000 40mm SWA and Celestron 31mm Axiom LX due to the even wider FOV. I got rid of a pair of 25mm and 9mm plossls as I just couldn't stand them after using wider AFOV eyepieces with better eye relief.

 

As for that ES 14mm UWA, I'd definitely say yes, get another one. I really like my 14mm UWAs in my BV.

I only have one pair of Burgess 17mm WA eyepieces. But I just ordered a pair of inexpensive SVBONY 7-21mm zooms (less than $50 each) to help me decide on what mags work best on planets. Then I'll buy a couple more dedicated pairs and sell the zooms. Or maybe I'll keep the zooms if they turn out to be good performers!

I’ve got Denk II with a power switch that have worked for me for years with just 24Pans. Now I use them for solar 24Pans, 15APMs and 10 APMs looking for a second 6mm Delos to over 200X when needed.

I've only spent a few hours behind the Orion linear binoviewer and only have three pairs of EPs at this time.

 

- 26mm Celestron silver tops (multi-coated not fully coated)

- 18mm Baader classic orthos

- 15mm Apertura SWAs

 

So far I like the 18mm BCOs the best overall in the 80mm and the C11 with the 26mm silver tops 2nd best in the C11. I don't really like the 15mm SWAs in either but need to give them more time for a final call. I've also not done any barlow viewing and my opinions may change once I try 2x and 2.5x in the various combinations.

 

Viewing cyclops style in the 80mm I like the 9mm DeLite the best so I need to spend some time with the 18mm BCOs and the 2x. I have not had the conditions to try magnifications over about 160x. This is probably why I'm still on the fence regarding the 15mm SWAs since they are 186x in the C11.

 

I don't have any recommendations but it's sure helpful to hear what others are doing. And I'm not a fan of less than about 12mm of eye relief, with more like 15mm preferred.

Swapping amplifiers in the nosepiece is a good way to go. No need for multiple pairs. Just Starguiders and plossls here.

Relative newbie here...I have an Orion XT10g since September and recently bought the MaxBright II and have used the Explore Scientific 82 degree 14mm and 8.8mm pairs.  I have had very good results with both so far, but have only had a couple of nights with them.  I have a pair of the 68 degree 24mm on order.   I've used the 14 the most overall but have enjoyed the 8.8 on planets.

My Omegon 1.6x OCA arrived a month early, and although I only had a couple of minutes to test it out in between clouds, it does indeed come to focus, and it does indeed provide less magnification than the 2x that came with my Orion binoviewer.

 

YASS!

 

Unless there are hidden flaws I didn’t notice, this will turn out to be an excellent and relatively inexpensive ($35) upgrade!

 

I expected it to ship from China on a boat from the ~1 month shipping estimate, but to my surprise, it originated from Germany!

 

And the seller even included the tiniest little bag of Haribo gummy bears in the box to sweeten the deal ;)

I've been binoviewing a good while & have gathered far too many eyepieces. These are organised in two sets

 

Shallow space - strictly for the best nights

16 ZAO II / 10 ZAO II / 7.5 LE / 5 LE

I'll use a GPC or Barlow most of the time, The LE's come out when I want to span a large magnification range.

 

More general

35 Masuyama / 22 LVW / 14, 10 & 6 Delos / 5 XW.

 

This spans what my scopes are usefully capable of while binoviewing - exit pupils of 0.55 to 4.8 mm.

 

Provided your focuser is up to it and you're using Mk V's or MBII's, Delos and XW's work really well. Be very sure of your collimation before venturing below 10 mm. Also - for others who may read this - Delos and XW don't work in Denk II's - the collet interferes with the 'safety' cut out.

I use a pair of Baader Mark IV zooms with an Orion Binoviewer and am very happy with the setup.

Only quirk is that the Orion Binoviewer does not have a diopter lock (not sure if other brands do) so when trying to change the focal length I have to hold the diopter collar while I rotate the Zoom.

Mainly use this for planetary and moon observation.

The Orion linear binoviewer is the same with no diopter lock. You have to hold the diopter while loosening and tightening the EP lock ring. A bit annoying but manageable. Some type of custom spring lock for the EPs on a binoviewer would be nice. Something where you pinch with your thumb and index finger to momentarily release the clamping for a quick EP change.

i currently have a pair of 17.5 Morpheus and a pair of Baader Mark III zooms.

 

i would like to pair up my 35mm psuedomasuyama and the 9mm Morpheus and maybe move away from the zooms.  they are great for being so flexible, i just don't find them to be comfortable or pleasing to use.

I'm curious to see how you like these zooms in the bino.

 

i just ordered one for my son to use...hard to beat the price.

I have too many - though they’ve been collected for different purposes (mainly solar ha, WL, lunar) with two different scopes and two binoviewers. Have a Maxbright II and just about to replace my Mk V with one of Denis’s Zeiss ‘Apo’ BVs. Mk V just too heavy for my set up. Anyway, my pairs are:
TV Plossls 40mm, 32mm, 20mm, 15mm, 11mm.
Celestron Ultimas 30mm, Fujiyama orthos 25mm. Zeiss OPMIs 25mm, TV Panoptic 24mm, TV Delites 18.2mm.

NIKON  7-21 zooms

Prefer to spend my time observing vs fumbling with pairs of EPs.

Have a few other pairs, but 95% of the time its just the Nikons in there, usually all i take out with the scope

 

When my 17.5-inch " BVer " is completed, the resident pair will be Baader Mk4 zooms

For now, only my Zeiss W-PL 10/23's. For my next binoviewer, I'm still figuring out wether I'll change magnifications with GPC/Powermates, or two more pairs of eyepieces.

15mm Televue Plossls on my Baader Mark V with 1.25x and 2.6x compensators.

Was also planning to use a pair of Tak LE 12.5mm, but 2'nd one is lost somewhere in covid-maddness. bawling.gif

Just getting back into viewing after 15 years on the sidelines.  But when I was viewing, it was always with Binoviewers.  Went through a lot of eyepieces, but ended up with these pairs and a Denk II w/ power switch in my XT10:

 

Current Eyepieces
Previously Owned Eyepieces
24mm Panoptics

13mm Naglers

10.5mm Pentax XL

9mm UO Ortho

7mm UO Ortho

 

These are the other pairs I have tried:

 

32mm GTO Plossl (2)
25mm Orion Epic ED-2 (2)
25mm Sirrius Plossl (2)
24.5mm Siebert Ultra (2)
18mm UO ortho (2)
16mm Nagler type 5 (2)
15mm Televue Panoptic (2)
14mm Meade Ultra Wide
12.5mm UO Ortho (2)
11mm Televue plossl (2)
10mm Sirrius Plossl (2)
10mm Antares Ultima (2)
9mm Orion Expanse (2)
9mm Antares HD Orthos (2)
9mm Nagler tpye 6 (2)
8mm Edmund RKE
7.4-22mm GTO Zoom (2)

 

I now have a set of Denk Binotrons with the PowerSwitch and 2 different OCS's.  I think I can get by with 2 pairs of EPs for everything:

 

21mm Denkmeier

14mm Radians

 

That gets me from 74x to 386x.  I am mostly a planetary viewer, so don't feel the need for super wide field.

 

You can check out my Binoviewers page and see how nuts I was:  https://www.tomhole....my/binoviewers/

 

This time around I know exactly what I prefer.
