I got a chance to compare ES 24mm, Brandon 24mm and Tak LE 30mm briefly with TOA 130 refractor(1.25x GPC). 

Venus(Tak and ES)

Beehive cluster(Tak, ES and Brandon). 

 

Both Tak LE and ES 24 provided sharpest crescent of Venus, not much difference other than at different mags.

 

For the first time I could view the Venus at Zenith(little bit south at my Southern California location) around 3:30pm in broad day light and track it until it appeared at west in the evening.

 

When observing Beehive cluster for 30 min or so, I did not notice any difference between 3 eyepieces. Overall I liked the view from ES 24 and it is very easy to get the full FOV(When I tried in daytime, it wasn't easy). I liked the sparkle of stars from all 3 eyepieces. All the faintest stars that were observable in Brandon 24mm, I could see them in both ES and Tak LE(even with less magnification). I tried to nice the background glow between Brandon and ES 24, I did not see any noticeable difference). 

 

All 3 pairs are excellent and I will keep them all. 

 

I really liked ES 24 more than I expected even with their weight, but I would hesitate to add more wide angle(>60) eyepieces in my line up. Except may be a 9mm Morpheus. 

 

I have 12.5mm Tak Abbe are on order from TNR, looking forward to receive them in a week or two. For upcoming planet viewing , I would also like a 7.5mm LE, instead of using a barlow or higher mag GPCs.

Added a pair of Datyson 32mm Plossls to go with my bino viewer on the Renaissance.

 

Good eye relief & easy exit pupil, unlike the TV 32mm I once had. The Datyson are more like 35mm Ultimas for comfort. Not quite TV 40mm class though, which are the best.

24 Panoptics

17.5 Morpheus 

12.5 Morpheus 

9 Morpheus 
8.5 Pentax XF

7.5 Tak LE

6.5 Morpheus 

 

I ordered the Pentax and Tak EPs recently and I’m still waiting for them to arrive. I’m going to compare them to the 9 and 6.5 Morpheus to see which I like better. The Morpheus are great, but sometimes I wonder if a slightly narrower FOV would be better so my eyes aren’t straining to look towards the edges.

I wish that I could binoview with Morpheuses, but my eyes are too close together.

Mine are too. My widest AFOV pair are Nikon NAV SW 17.5s, which are also the fattest. Nose room is another thing too.

I ordered a 2.6x GPC for my MB2 and now I’m looking for some EP suggestions for my 4” f9 refractor.  My current pairs are 24 Panoptics, 17.5 Morpheus, 12.5 Morpheus and 7.5 Tak LE. I’m thinking of using orthos to fill the gaps for lunar and planetary viewing. Maybe a 25, 20, 15 and maybe a 10mm. I’m considering the TV plossl and Tak Abbe ortho. It seems the Ultimas would be an option if I can find them used. My only requirement is that there be at least 10mm of eye relief. Does anyone have suggestions?

Honestly speaking I think you're good to go with what you already have. waytogo.gif I was using 20mm and 12.5mm pairs on Mark V with 100ED (4" f9 refractor).

Do you have 1.25x and/or 1.7x GPC ? If not, it will be better (and MUCH cheaper) option and will provide you 2x times more magnification options.

Since my last post on this topic in 2018 I got a second 17mm TV smoothie, then pairs of 7.4mm, 10.5, 13, and 21mm. And a pair of current 25mm TV plossls. They are my favorite set by far (versus other narrow FOV eyepieces). Eye relief gets short starting with the 13mm. But if you can stand it, you can get very nice views of planets and double stars with the 7.4 and 10.5. They are warm in color, as many have noticed. Jupiter's GRS, for example, is bright red compared to other EPs.

 

I have a few orthos that are nice, and neutral in color. 6mm, 18, and 25mm Kokusai Kohki, which you can get new at Agena and elsewhere. And two Takahashi Abbe orthos (9mm and 12.5mm). And some MIJ Meade 3000 & 4000 plossls. They are all nice, but I usually prefer the TVs over them. I keep the TAOs around since so many people praise them but they have never wowed me like the TV plossls, which seem to have the best contrast and transmission of anything I've used. But the TAOs have noticeably better ER compared to the plossls, esp. if you fold the rubber eyecup down. And the 6mm KK, which has no rubber eye guard, is about as comfortable as the 10.5mm plossl (which also does not have a built-in rubber eye guard). That is, I can see the field stop on each at about the same distance. The 18mm and 25mm KK are VERY comfortable in binoviewers. The Meade 3000 (I have 6.7mm & 9.5 pairs; 16 & 25 singles) are surprisingly very good, almost as good as the TVs. I wish I had the 16mm and 25mm in pairs, but they are hard to find.

 

Honestly, for the moon I tend to like wider FOV. Your Morphei and Tak LE are probably fantastic, no? I use 68-100° Meades (5.5mm, 8.8, 21) and Explore Scientifics (11mm and 16). Great to OK eye relief on all of these.

Yes, I have the 1.7x as well which works very well with the 7.5mm LE. I liked that view so much I wanted to try a longer length 4-element ortho or Plössl to see if there is any improvement over the LE. A 12.5mm TAO using the 2.6x would give me about the same magnification as the 7.5 LE using the 2.6x. It seems the long orthos are also nice on DSOs.

I think I’m going to look for a pair of TV Plössl. Perhaps the 15mm or 20mm. 
 

The moon looks awesome with the Morpheus and LE. But I actually prefer the narrower FOV at higher powers because I’m usually focusing on a specific lunar feature.

 

I have slow motion controls on my grab & go mount and also a tracking mount. So narrower FOVs aren’t a big problem. Plus, I have the Morpheus if I want a wider FOV.

What I'm hoping will work out (will know the answer in a couple of weeks)
 

1. Zeiss W-PL 10x/23

2. Nikon MCII 7-21 zoom

 

That's it.

I had the best view of Jupiter in my life last night using my BV in a 140mm f/7 refractor, straight through, with no diagonal, no OCA.   I was using two Baader MKIV zooms, which top out at 8mm.  I wish I had shorter focal length EP pairs on hand.   I get good views binoviewing with a diagonal and OCA, but there are likely optical axis errors that are adding up to slightly degrade the image.   The straight through, unobstructed view while using a self centering  eyepiece adapter on the scope was really something else.
