I also love my T6 Nagler eyepieces. I have the 5 mm and 13 mm focal lengths. I compared my 13 mm T6 directly against the 12.5 mm TPL on Saturn on the same night. The contrast was equal on the planet Saturn using my refractor. I compared them for magnitude reach also and there was no faint star visible in the TPL, which was not visible in the Nagler. On deep sky, there was no contest with sharp stars and a wide view to the edge favoring the Nagler compared to the TPL, which is to be expected. 

I compared in a separate session my 5mm T6 Nagler vs my Pentax 5 mm XW and the Nagler gave cleaner splits on Izar. I did get a second 12.5 mm TPL for my Bino Vue, because I intended only to use it for planetary viewing with my 2X amplifier giving a wonderful 0.78 exit pupil in my upcoming f/8 refractor and because they provide a very slightly greater magnification than a pair of 13 mm Nagler’s.

Denis, would love to see you compare the 16mm Nagler to the Masuyama 16mm 85* someday. I would do it myself, but I long ago sold my 16mm Naglers and assume I had a good reason but have forgotten. Would feel stupid to buy them again only to sell…

I’m guessing it was the pincushion distortion that plagues most Televue wide field eyepieces, but really don’t remember, it was likely 15+ years ago.

I have read good things about this line of eyepiece. In my binoviewer I use a pair of 17.5 mm Morpheus eyepieces, which give a very comfortable and generous afov for viewing the Moon and would never consider letting them go, except for the fact that I recently learned that this line of eyepiece uses lanthanum glass, which I would like to avoid in future eyepiece purchases, because I have read that lanthanum glass eats blue wavelengths to some extent, based upon comments I have read from CN fora. Do the Masuyama eyepieces contain lanthanum lens elements? I could not find that information readily. Thanks.

Unfortunately I’m not sure about the lanthanum. The Masus have been around for quite a while though, before the lanthanum craze, so I’d be surprised if they had any. For what it’s worth I sold my 17.5mm Morpheus (they did not impress me with planetary), while the 16mm Masuyamas are among my favorite eyepieces. As long as you’re running reasonably long effective focal ratios I’d be surprised if the Morpheus performed better in any category save eye relief (though I actually find the Masu much more comfortable than the Morpheus despite the shorter eye relief, they are so much smaller and more ergonomic). That said eyepieces are so personal, take this with the usual grain of salt.

I can see difference between TPL and Nagler eyepeices: TPLs provide COLDER image, with less scatter, and tiny bit sharper views (I test in monoviewing using my LZOS 180mm APO, and using Tak 2" mirror diagonal), and views are pure crystal clean.

 

I also tested in bino mode Naglers vs TPLs, using my:

 

1. Mark V bino + GPC 1.25x: both Naglers and TPLs in that setup provide some very small amount of false colours, fault by Mark V all prism system. TPLs provide COLDER image, with less scatter, and tiny bit sharper views.

 

2. Mark V bino WITHOUT GPC: both Naglers and TPLs in that setup provide significant amount of false colours, fault by Mark V all prism system. TPLs provide COLDER image, with less scatter, and tiny bit sharper views.

 

3. APO SS bino without GPC: both Naglers and TPLs in that setup provide pure crystal clean image, without any false colours. TPLs provide COLDER image, with less scatter, and tiny bit sharper views.

 

4. APO SS bino + GPC 1.25x: both Naglers and TPLs in that setup provide pure crystal clean image, without any false colours. TPLs provide COLDER image, with less scatter, and tiny bit sharper views.

 

 

Rubber eyeguards removed on both TPLs and Naglers:

Naglers provide much wider FOV, and I dont have to touch Naglers and I can easily see whole FOV.

 

In TPLs, 12.5mm and shorter I have to touch eyepieces.

Here I have a Pair of TV 11T6 Naglers mounted on an early 1998 Zeiss viewer, eyepiece focusers shown on these viewers were made by Richard Lapides, the original viewer did not come with eyepiece focusers.

This combination works best for viewing the Moon with my 6" F12 Maksutov.

Bit out of topic:
Delites and Deloses are not comfortable at all for my facial structure at all, even at lowest position of sliding part, but when they are decloacked, then both series works perfectly.

But then I have big problem with blackouts, + if I have full double line I dont know which is which focal + they looks SUPERUGLY for my taste.

Naglers seems to be best for binoviewing from TeleVues production combining many factors and compromises.

Kind regards,
Denis

FYI the Pentax XF eyecups fit the Delite's well. Naglers are more immersive though. Had pairs of 7, 9 and 11s. The 7mm I did not like for some reason. Wasn't as comfortable as the others.

Used my Nagler 3-6 zooms last night, they merge perfectly for my eyes. Best to use non-rotating eyepiece holders or the zoom function becomes problematic.  In a 90mm scope, I was pleased to see how well they worked at the end of my “1/3” messier marathon.  They give up just a smidge when compared to my 7mm Tak orthos, but the Tak’s don’t zoom…. The Nagler zooms may be the only Televues that stay in the stable. The 9mms are great in binoviewers for me too, but I find myself reaching for Tak 12.5 TPLs far more often these days…

11mm nagler type 6 has very good contrast and clarity, not that much different than Fujiyama 9mm orthoscopic. They barlow well and I'll never sell my pair. Took awhile to find them used!

I liked the 11mm too. The equal of the 13mm T6 pair which I now use for widefield binoviewing

[havasman]

Well before I used binoviewers I read others agreeing that wide AFOV eyepieces were wasted and not effective in BV's. So I picked up very good but not ultrapremium Vixen SLV pairs for Ha solar observing with Denks in a Lunt 80MT and they work very well. But when I read others and particularly Doug Culbertson saying their 13T6's were their favorites I had cause to rethink my strategy. That ep has been a top favorite in all my scopes for cyclops observing and I picked up a second.

 

Sure enough, the 13T6 is now my favorite BV pair and with the Denk power switch in play they are often the only eyepieces I use in an Ha session.

TV eyepieces are good for general observing like Sun/day Venus Mercury, some open clusters etc, for which I use 24 Pan, 16,11,7 N6. But for planets "Hi end" planetary eyepieces are the way to go... or are they? I just got myself the ultimate TV - N7 aka Apollo 11 sharp eyepieces. We will see how they compare once the clouds go away.

Very nice - look forward to your thoughts slavicek

[denis0007dl]

Awsome, keep us posted about both optical performance, and ergonomics and comfort of observing.

[RichA]

...rubber eyeguards removed for maximum comfort.

More pictures and impressions will follow....

 

Denis

Don't know why they don't use batwing eyeguards.  Even when not binoviewing they are the only eyeguards that actually screen out stray light.

[denis0007dl]

Agree.

Winged eyeguards like Morpheus line have are awsome.

Nagler T6 rubber eyeguards are very uncomfortable/hard.
