    Default Is there a case for non-Naglers



    I have a couple good quality refractors and a set of Naglers: 31, 22, 16, 12, 9, 7, 5, 2.5 (and a 4mm Radian that I don't use very often). I don't look at planets (more than for 30 seconds every once in a while, and the moon every few months for a few minutes). Is there a strong case for looking at any other lenses? I love my Naglers, but want to make sure there isn't some reason I should have something else, that outproforms under some circumstances. Thanks,
    JD

    You have more eyepieces than most observers do and I would say that you are set unless you like the even wider apparent field of view Ethos series.

    Default Thanks

    I have been eyeing the Ethos, but they all fall either with the same magnification and or FOV as others in my collection, so I have been able to stave off the urge... so far. I am sure it will not last for ever. I have poor impulse control. JD

    I have been waiting for a long focal length Ethos eyepiece to obtain a wider field of view at low magnification. For twenty years I have been making do with a 32mm Televue Widefield yielding a true field of view of .66°. I did get a Meade 30mm Ultra Wide Angle over a year ago but I have not gotten around to fabricating a counter weight. The 30mm UWA yields a true field of .78° but more field is always better in my opinion.

    Default Sounds good to me as well

    However with the increasing cost as the focal lenth has increased, a 21mm Ethos will likely cost more than your telescope. ... but I would have to be a buyer of one of those to. JD

    btw Ted, you have good impulse control. My idea of waiting for a better lens is a week before I find something, certainly not 20 years. Good for you.

    JD, I think the main differences you would see in going beyond your Naglers would be in variances in image coloration and perhaps contrast--but all very, very slight. A little field of view variance, too, but beyond a Nagler, it's just icing on the cake. However, it's all about what YOU want. If you have the dough and the curiosity, an Ethos is about the only step up, I'd guess. Then, there's some Vixens and Pentaxes, too. I guess, even if you can't see the improvement though, it's kinda like me with music equipment--having available headroom makes me feel better. I'd say that if your curiosity can't be satisfied any other way, go for it. You can always sell it later if it doesn't suit you. Then, you would know, and your curiosity would leave you alone. Heh, heh, for awhile.

    Default Ethos

    Thanks for your point of view. It sounds like the place to go is Ethos. I have been holding back because of the cost. But I have seldom heard this kind of buzz about a product without the benefit being real. I think I'll wait for my will power to drop for a moment and get a 13mm or 17mm. My favorite Nagler is the 20mmm which has a FOV of nearly the same as the 17mm... so perhaps I'll start with the 13mm. JD
