    Default What 14ish premium eyepiece



    I own a Nagler 13mm but I am gravitating toward the 70ish fov type. What one would you buy Pentax 14, Delos 14, or stay with the excellent Nagler 13. If you check my signature you will see my eclectic preferences.

    Naglers have an 82° AFOV is that right? I've heard lots of good stuff about the Pentax's. If I wanted a premium 70°, that'd be where I'd lean I think. Of course, I've never peaked through a TV eyepiece.

    My Chevy driving butt feels like its putting on airs with the ES EP's.

    Delos 14mm is probably going to fit well with your line up, although I'm not sure it'd be much different to the 13 Nagler (if it's a T6?). I like the Delos more for their ER than their FoV, although they are quite immersive with their big lenses and pull up eye cups. I can't really talk though as I've not looked through either, but own lots of other Delos eyepieces, which I love! Mind you I've never looked through these with a really nice refractor of Cassegrain either!

    Another option on sale at Agena is the Vixen LVW 13mm. The 17mm I looked through compared well with the 17.3 Delos. A friend onf mine has a Tak120TSA and he swears by them.

    It kinda comes down to how you feel about the 82° AFOV. For some that is too much eye movement, for others (like myself) it is just right, while others still want more and go to the 100° range. The Pentax is good, but the 14mm is known for its field curvature. Depending upon how much that bugs a person, that may or may not be a deal breaker. It doesn't bother me, because if it did I wouldn't hang on to my ES 82 14mm, which also has this problem. But for my eye its insignificant. Even with the FC issue, the Pentax ss still a very popular EP. The Delos is pretty flat comparatively so that might be a good alternative. All the ones you mention are fine eyepieces for their own reasons. Which one is right for you is based on your individual preferences.

    Our club did a shoot out between like mm Delos and Pentax XW's maybe 2-3 years ago using one scope on the same object back to back...

    The results were "almost" unamanus that the Pentax won across the board ...HOWEVER it boiled down to nit picking and very subtle things like the color tone of the view etc so difference was so darn little not a one of us would object to have either brand in our cases NOR would any one sell one and replace it with the other in our case... The Pentax 20 mm however was clearly not as good as the Delos 17 point something ...as the Pentax had some field curvature which may or may have been the result of the magnification difference between the two ...

    Bottom line flip a coin and smile whichever side comes up...

    BTW... I sold a few of my Naglers may 6-7 years ago and replaced them with mostly Pentax XW's for high to medium power and Televue Panoptics for low power.. (The Delos were not on the market then ) .

    My old eyes just could no longer handle the ultra wide angle Naglers comfortably since I had to shift my eyes all over the place... SO I can understand why you are thinking of dropping down to a 68-70 degree FOV eyepiece...

    Hello Lola,

    checking your eclectic preferences, I'd recommend you to go for the Zeiss BWW series 68° FOV, sharp edge to edge evenon on my 6" F/5 achro refractor, and the highest light transmission and highest contrast, even winning over the Swarovski eyepieces.

    The Zeiss BWW series fix focus eyepieces has been discontinued, but you may find here:
    Kay Optical - Telescopes and Binoculars Sales, Servicing and Repairs
    The adapter bayonett-to-1.25" may add around 100 USD to the costs.
    The Zeiss broadband T* multicoatings top even the SMC of Pentax/Ricoh, even if the concept of the SMC has been derived from Zeiss T*, but Ricoh uses the Far East glass standards, contrary to Schott/Zeiss.

    The Zeiss (and the Swarovski) eyepieces have revealed to my eyes some tough galaxies and tough nebulae, I have not seen before with the other eyepieces.

    Can't offer you anything better, that's the 'champagne' among the eyepieces.

    Best,

    JG

    I suspect that might be me with the LVW's. Plusses and minuses, Plusses, I find them very comfortable to use with the 20mm eye relief, gives me the option of wearing spectacles instead of contacts, with my astigmatism this is a consideration. Also they seem to work well in a variety of telescopes. Minuses, they do everything well but are not "best in class" at anything. Also there is an irritating gap between the 8mm and 13mm which becomes very apparent with my Nexstar 8SE, I have a 10mm Delos to plug the gap. A good set of compromises for me though. The LVW's are very consistent across the lineup but if I had to I would pick the 22mm the 13mm and the 8mm as being the pick of the bunch. Having said that I think the Delos are slightly better optically but, to my mind, not quite as comfortable to use. But if I was starting over I might, just might, pick the Delos instead.
