People have been asking for this for a long time. I'm glad to see Televue keeping up with innovating and listening to us.

 

I wonder if the 24 Pan will stay alive. I'm guessing the 24 Delo will be big and heavy, so probably yes.

Excited and thinking on which objects to use this nice looking Delos on. 115x ~ 2.4mm Exit Pupil with the 11" SCT and 25x ~ 4mm exit pupil with the refractor.

 

Should be great with the refractor for sure. Cannot replace the 25mm ES 100 for Open Clusters. If I can add a 1.4-1.6x Barlow Lens on it for Galaxies though...hmm.gif

Very close to weight and TFOV to Nagler 7 19mm, similar eye relief.

Well,that's only true if:

 

1. 19NT7 has 19mm effective eye relief

2. Delos 24 has 19mm effective eye relief, if eye lens is concave (22mm - ~2 to 4mm ER = ~19 to 20mm ER)

Indeed. This is going to be a real treat!

Yeah I noticed the lack of those. I wonder if Televue will start manufacturing all their oculars slowly without undercuts now?

Either that, or Televue is just simply going to start bringing out new designs in oculars without undercuts from now on.

The 24mm Delos is a response to feedback it seems. I've seen many many posts wishing for a longer focal length Delos, and most of those threads come to an end when someone, usually Don, comments that the odd focal length of the last Delos in the series, the 17.3mm Delos, implies a design constrant, and therefore, the natural end to the Delos line.

 

It would seem to me that the 24mm Delos is probably a complete redesign, and not a scaled design from the Delos.

There was a thread recently that the new batch of 24 Panoptics also lack undercuts.

 

Seems we might be witnessing the end of undercuts at Tele Vue.

I believe any eyepiece design whereby eye relief remains somewhat invariant of focal length would not be a scaled design. All DeLites and Delos would then not be scaled like Plossls and Orthos are), But yes it's possible that the 24mm Delos is an even more significant departure from the general design of the shorter focal lengths. I guess time will tell.

 

One thing about Tele Vue is that they love to remain as consistent as possible, so I would imagine that this 24 Delos will perform and feel like the others in the line regardless of how they got there.

Extremely doubtful that the 24 Delos will replace the 24 pan. I seriously doubt that. Why?

 

1. 24 pan has shorter eye relief, which works better for a lot of folks using them for binos

2. 24mm Delos is pretty fat- can it be used for binos? Maybe, maybe not.

 

The 24 pan is a very popular bino pair EP.

Also, if you remember not too long ago, someone posted about the 24 Pan being cosmetically revamped and it didn’t have undercuts either. I seriously wouldn’t be surprised if Televue are just going to start manufacturing all their oculars without undercuts in time.

In other words, Televue told Don “challenge accepted!” lol.

Plus…when it comes to undercuts going away…

 

some will be glad about it, some will be mad about it and then you have me that doesn’t care one way or the other about it. shrug.gif

Seems like in the survey they sent out last year the three big responses were:

 

1. Long eye relief Naglers

2. 2" Delos

3. No undercuts

 

And now only a couple of months later and Televue nailed it

I know…someone actually listened to their customers. A rarity in today’s times.

Wow! That IS fairly lightweight to what I expected!
