I have recently moved down in aperture to 80-100mm +- refractors which are incredibly easy to use and show significant detail visually. I am putting together a set of 1 1/4" eyepieces to use and am having trouble with the various 1 1/4" Nagers. Can anyone recommend which 1 1/4" Naglers are best for visual observations with small triplet refractors? Other 1 1/4" eyepieces you would recommend especially when putting together a set?

It might be valuable to know what troubles you are having. I use a set of 13/5/3.5/2.5T6's plus AT 7mm UWA in my refractors with very good success. The 13T6 is probably the most used of them. Shorter focal lengths include a 20T5 that sees a lot of focuser time in the NP101is and some in the AT150EDL, an ES68 24 that's a fixture in my AT80ED and both 31T5 and 21E that get used ~often in the AT150EDL. A pair of 13T6's in Denk binoviewers are my go-to Ha solar tools. While none of those are triplets I think any differences are insignificant for these purposes. The ES68 could as easily be a 24Pan and work as well.

I believe just an aperture size is not enough to make right selection.

 

It would be nice to add scope N-number, preferred objects, sensitivity to near exit pupil, etc.

 

Without the info we can just tell you about our experience and preferences. E.g. I like my couple of 16 mm Nagler type-5 and 11 mm Nagler type-6

I use the Nagler zooms a lot with my refractors. They are not widefield eyepieces though, unlike the fixed focal length Naglers.

 

The Nager Type 6's are compact and pretty good performers in such scopes.

Perhaps a moderator could change the spelling of Nader to Nagler in the title so the thread could be looked up later.

Done!

I have had very good results with use of my 16, 13, 7, 5 & 3.5 mm Nagler T6 eyepieces in my Stellarvue SVX-90T f/6 refractor. As another poster noted - object being viewed, magnification, field of view, eye relief, exit pupil, and other specifics all matter. On either side of that list I use a 24mm Panoptic and a 3mm DeLite. I am very pleased performance of all. Balance of the OTA in my manual alt-az mount is also not challenged with the light weight of all these eyepieces.

Jim:

 

I have nearly all the 1.25 inch Type 5 and Type 6 Naglers, I only lack the 2.5 mm.

 

I think of them all as very good eyepieces and essentially interchangeable.

 

So.. exactly are you trying to decide? 

 

In a smaller, shorter focal length scope, the 16 mm-13mm-11mm-9 mm group is pretty close and depending on what I'm observing and what scope I'm using, I may leave the 11 mm and 13 mm in the case. A 12 mm Type 6 would be perfect for smaller scopes.  

 

I find those more useful in large fastcm scopes. 

 

The 9 mm-7 mm - 5 mm - 3.5 mm + a 2x Barlow cover all my high magnifications needs.

 

I like the 22 mm Panoptic with the 2 inch skirt removed as a low power 1.25 inch wide field/finder.. it's nice not to have to swap out to a 2 inch.  The 24 mm Panoptic would serve this purpose.

So thinking about this thread and a nearly clear horizon at sunset, I setup the 4 inch F/5.4 TV with selected Type 5 and Type 6 Naglers.

 

I made the radical decision to leave the 9 mm in the eyepiece case, I never do that.

 

The set: 22 mm, 16 mm, 11 mm, 7 mm, 5 mm, 3.5 mm.

 

The magnifications: 24.5x, 34x, 49x, 77x, 108x, 154x.

I really rate the type 6 Naglers. I use the 9 mm and 13 mm in short focal length refractors.

 

The 13 mm is really impressive in 80/840 and 100/800 refractors.

 

Similar in size the Delite's are also very good in shorter focal lengths. 

 

For very high power I use Takahashi TOA eyepieces. I have the 4.0  and 3.3 mm TOA's.

 

To be honest the type 6's are great in all manner of telescope that uses a 1.25" focuser.

[lwbehney]

My 13 mm T6 Nagler is just as good for transparency and contrast as my TPL 12.5 mm on star fields  or using the same Barlow with them on Saturn and stars.  I almost always end up using it any night I am observing. 

[RAKing]

I have all the T6 Naglers, the 16T5 Nagler, and the two small Panoptics - 19 and 24mm.  I can mix and match these, along with my Zeiss Abbe Barlow, to cover a lot of small telescope needs.

 

The best view I ever got of Saturn was with a 5mm T6 Nagler in my TEC 140.  It was 196x of crystal-clear awesomeness - looked just like a photograph!  I must have spent ten minutes (or more) with it.  Unforgettable!

Here is the small Pelican 1200 case that I use.  This is setup for the FC-100DZ that I plan to use tonight.  The Zeiss barlow is in the top row to the left.  Then comes the 24 Pan, followed by an 11, 9, 7, and 5mm T6 Nagler.  This handful of eyepieces covers everything I need from 33x (24 Pan) to 320x (5T6 + 2x Barlow).

The Naglers will be about as sharp as anything in a 100mm refractor, in my experience. If the views aren’t sharp, it probably isn’t the Naglers. Are you having trouble reaching focus? Want more eye relief? As stated, what trouble are you having with the Naglers? There are other comparable options, but nothing markedly sharper.
