Refractors Reflectors Two Cats A few eyepieces
Quote:Funny thing is, I have a couple of Victorian era Huygens EP'sthat perform very well at F15. They have VERY good surface polish. Don't use them on a regular basis (one is about 55mm FL).
Quote:Modified Achromat - 40° AFOV, 3 element... Here's a nice review:http://www.chuckhawks.com/common_eyepiece_designs.htmThe older ones, made in Japan, like those in the photo share a similar barrel and outer design to the Meade Series II Orthos. The are not nearly as good as the Orthos, but the 25mm seemed to work fine in my 60mm f/16.7 Carton refractor. Jaimo!
Quote:The ones i have are not that old, have rubber eyecups.They came in a pretty heavy blue hinged case.The eyepieces are pretty heavy built, no plastic.Seems funny tho how lenses made today are junk but in 20 years are great!
Quote:Jon, I don't know what it is about the E.W.F., but I find it very appealing, it has been on my radar for some time.Jaimo!
Quote:perhaps thats why i have always kept one or 2 around, Old school as it is I have always liked Kellners, I don't waer my glasses viewing because I don't have astigmatism so the low relief in higher powers isn't an issue for me.BUT for under $40.00 for the whole set of 5 and a nice heavy case It is a great bargain....to me

It is an interesting eyepiece, I don't use it a lot but I use it more than my 40mm Celestron Plossl. In a side by side comparison, the Celestron Plossl wins on every point but when the time comes to choose an eyepiece, I always choose the EWF... Go figureJon

Not bad. Where do you find those deals?
Quote:But I hadn;t seen the 17 and 6mmin the MA, usually see the 25 and 9mm which I like.
