I really don't think these are super classics or anything, but I have a real soft spot for the Meade MA eyepieces that came with my SCT's. I have a 25mm and 9mm for use with my 2080 LX6 Premier (although they were acquired separately). I was really surprised how sharp they both are on Jupiter. They have a bit more of a blue hue versus my Tele Vue eyepieces. I really like them!
The 25 mm Meade MA's like the one in your photo seem to congregate at my house. They're good eyepieces so I give them away with scopes but the seem to keep coming. Roght now I have three , two appear identical and one is shorter..
I really like the brass construction, they just seem like "this is how an eyepiece should be made.
Macdonjh reiterated the importance of the telescope in choosing eyepieces for the evening . A fast scope really jerks the light around and to get it all going where it's supposed to go requires more than three or four elements .
But in a slow scope where the light is bent by gently massaging it, Erfles, Kellners and orthos come into their own. My one slow scope is my one classic, a Meade 310. At F/11, this 80 mm achro is slow enough that such eyepieces can shine.
I do have a complete set of Meade Series 2 Orthos, the 4, 6, 9, 12.5, 18 and 25 mm's that do nicely in such scopes, the 18 mm and 25 mm really provide very nice views. I also include in that set the Meade MA40 mm EWF, the same blue and white lettering as the orthos.
The EWF is supposed to mean Extra Wide Field but its less than 40 degrees. But it gives the illusion of providing a wide field view. I find that eyepieces with a large eye lens and a barrel that's only slightly larger than the lens create that "floating in space" illusion . I suspect that's what's going on with the 28 mm RKE .
I have to get that set back, along with my C4.5, its been on loan for more than 5 years. .
