Got back to Nagler T6 eyepieces for binoviewing, after longer time.

 

Here are some rare images on Naglers in bino mode, especially showing how beautifull lenses are on them...

 

Kind regards,

Denis

...rubber eyeguards removed for maximum comfort.

More pictures and impressions will follow....

My main pairs are 16mm T5s and 13mm, 9mm and 5mm T6s. I have always loved Naglers in a binoviewer. 

 

Edit: got my T6’s labeled wrong!

Awsome!

 

I also love 16mm T5, but even with rubber eyeguards removed, and due strongly concave eyelens, lenses get always fogged, and observing in any semi cold, and especially cold and very cold weather, and sometimes even in warm time, but optically they are FANTASTIC!

 

So far, I got new run of Nalgers T6 in focals:

3.5mm, 5mm, 9mm.

 

13mm and 7mm will come maybie in some 2 months +/-.

 

Also ordered Panoptics 19mm and 24mm in pairs, despite rectilinear distortion on them.

Do you also have eyelens fogging in Naglers 16mm T5?

[Doug Culbertson]

24mm Pans are great; I sometimes wonder why I sold mine, but I slightly prefer the 20mm Brandons that replaced them. To be honest, I really slightly prefer the ES68 24mm over the Pans, but they are too wide for my 60mm IPD to use in pairs. 

 

I think that you will love the 9mm and 5mm T6’s. I keep trying to talk myself out of the 3.5mm. 

[Doug Culbertson]

Do you also have eyelens fogging in Naglers 16mm T5?

No,  but I mostly use that pair for solar observing. If I get fogging, it’s because everything from my telescope to the binoviewers and eyepieces are fogging up from a rapid temperature change.

Denis,

 

I forgot to mention, regarding the 16mm T5, that I am a cold weather wimp, and seldom bother going out if it’s below 50°F/10°C,

For Nagler 16mm its also important facial structure around eyes.....

 

16mm Nagler in only Nagler in 1.25" line which suffer from false colours of exit pupil on daytime (same like all Naglers T5, where 31mm is worst by far), till you perfectly positioned eyes, and there Naglers T6 have advantage not having that effect.

 

Also, Nagler 16mm have blue ring of fire on fieldstop, whih is NOT case on Naglers T6.

 

Thus, 16mm have excellent field sharpness and contrast, and are smallest Naglers in 1.25" format, and IMO cuttest of all of them.

[denis0007dl]

Interestingly, I found Nagler 16mm to be more comfortable in bino mode, than in mono mode.

 

I think I had readed somewhere on forums same experience from other observers.

[Doug Culbertson]

I have tried the 31mm Nagler at least three times, but I just can’t use it well. Yes, the ring of fire is present in the 16mm when looking at terrestrial targets during the day, and the T6s do not display it at all. I still love the sharpness and contrast in the 16mm T5 though. 

 

At this point, unless I get out of the hobby, you would have to pry my T6 Naglers out of my cold dead hands.

I never thought about that. I will have to compare next time I get out again. 

[betacygni]

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.

Thanxs for input, it might happen sometimes in future.

Denis,

Yeah, my current threshold is 40° F.  Old bones.  You will very rarely find me out there below that number.  I never have fogging issues with either oculars or scopes because of that and by carefully monitoring the spread between temperature and dewpoint.  A too high wind gust figure also deters me from going out. 

 

But that 16mm Nagler Type 5 is one special eyepiece.

Have never seen any edge issues with my 16mm Nagler Type 5s in my Tele Vue Bino Vue.

 

I do agree that they're cute.  They do pack a lot of impressive power in a small package.  I like the Type 6s, too.

My pairs are 24Pan-16, 9,7 Nags

I have pondered adding the 13Nag, but also as I have a Baader 8-24 M-IV, getting a second one and giving that a try sounds interesting.

That has been my experience, too.  I love the 16T5 Naglers in the BV unit, but I like the big Pentax XW85 16.5mm eyepiece in mono mode.  Both of these are very comfortable in those jobs.

 

As for the T6 Naglers, I have almost a full set of pairs (13-5mm, including the 11).  I have used these along with the 16T5 and 24 Panoptics since I started binoviewing 15 years ago.  I also liked the Carl Zeiss orthos before my cataract surgery, but let them go in 2016.

All Naglers T6, when rubber eyeguards removed, my face absolutely does NOT touch eyepieces anywhere, meaning NO fogging eyelenses like I have in all Ethos line, China XWAs, Takahashi TPLs 12.5mm and below, and in Naglers T6 I can see whole FOV.

Simply brilliant!

[denis0007dl]

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

I also use the Nagler T6, it's a shame that there are no 4mm and 6mm versions. These eyepieces are ideal with the bino, especially for people with narrow eye relief. I use them with rubber eyeguards and can really crawl into them.

here is my collection for the APO-SS-Bino:
TV Nagler T6    2,5mm  
TV Nagler T6    3,5mm

TS UWAN          4,0mm 

TV Nagler T6     5,0mm   
TV Radian         6,0mm
TV Nagler T6     7,0mm

TV Nagler T6     9,0mm   

TV Nagler T6   11,0mm   
TV Nagler T6   13,0mm 

TV Nagler T5   16,0mm   
TV Panoptic     19,0mm   
TV Panoptic     24,0mm   

The close staggering of the focal lengths always allows me to achieve the maximum possible magnification that is still really sharp.

I wish TV continue making 2.5mm and 11mm T6 Naglers.

I have 9 and 11mm Nagler pairs that I use occasionally with my binoviewers, but to be honest I much prefer my Takahashi TPL'S for planetary observations. Which I have 9,12.5, 18 and 25mm pairs.

I do also use occasionally 7mm Delites and 15 and 20mm TelVue plossl's for planetary viewing as well.

I do use the 9 and 11mm Naglers as well as 24mm Panoptic pairs though if I using the binoviewers on deepsky objects.
