Alright, who bought the 26mm T5 on eBay for $700.00 today (4/22/25) ?????

 

Was on my Watchlist

 

(Don't answer this question)

Agreed Starman. That's why I wanted a 26mm T5, it's that ~40% from my 16mm T5 and entirely adequate as that one low power 82* to step up from the 16 vs the 22/31 combo. I'm actually fine now with the 30mm UFF. I'll contentedly wait for that T7.

 

Clear skies...

Back when I had a set of Naglers my low power was the 26mm T5 , wonderful eyepiece . The next step up in magnification was the 16mm T5 , another fabulous eyepiece . The remainder were T6's, the 5, 7 and 9mm .  I miss the 26mmT5 and the 16mmT5 quite a bit . Look how tiny the 16 T5 is , so much goodness packed into a small space .

What is the reason for including T5 when referring to the 26mm? There was only one version of the 26mm.

I was its type designation. The Type 5s included the 31, 26, 20 and 16. Like the type 4s included the 22, 17 and 12.

No, Televue had a 26mm Plossl. I have two for my binoviewer.

Because that's what it is a Nagler T5   . I hope that's alright with you.

I appreciate the clarification... we don't want someone confusing the 26mmT5 with the 26mm T4 or, even worse, the 26mmT1.

Haha, no man. It’s all good. Albie is a good guy, he’s just playing around with ya. Televue kinda did type classifications to choose a certain line that favors individual observers to their tastes and needs, like longer eye relief, wide 82* FOV, even wider 100* FOV and other factors.

 

Some folks love the lower focal end of 82* FOV and the Type 5s were designed for that, like being focal lengths 16 through 31. Others like the Panoptic line focus on flatter fields, but sacrifice FOV down to 68 degrees. Some folks liked a legendary mid range in the Type 4s that covered focal lengths 22, 17 and 12. Then there’s the Type 6 ‘minis’ I call them, due to their size, but don’t let them fool you! All are 1.25” oculars packing an 82 degree FOV punch in a super compact eyepiece. They come in 13, 9, 7, 5 & 3.5. 

 

in essence, if I wanted to stay strictly to an 82 degree FOV, I would choose the Type 5 and Type 6 lines of eyepieces. If I wanted only 100 degrees FOV, I could sell my house, private jet and small Caribbean Island to buy the entire line of Ethos. LOL! Also, if I didn’t care about the wide fields of view but was a stickler for flat fields and pinpoint stars right out to the field stop, I could purchase the Panoptic line. 
 

you kinda got my drift, Villa? Some, like me, mix and match different Televue lines to my desired applications for viewing objects from planetary viewing, star splitting, lunar, globs, open clusters, planetary nebulae and brighter nebulae.

 

all Televue is doing is designating the family type the ocular belongs to. Like you also shared, Televue also do another 26mm ocular, but in a Plossl design. It just indentifies the family line that the ocular comes from. 
 

p.s. Don’t forget about the Type 7s coming out real soon. That line will be covering mid to high power at 19, 14, 9 and 5.5. Supposedly the best of the best so far with highly polished lenses and exceptional 82 degree views.
