    Default Konig EP's?



    I was looking at 2in. EP's on Ebay and came across these...I know that Konig EP's have one less lens in them than do Plossl EP's. This seller implies that these may be manufactured by Pentax I believe by saying that "Super-Wide-Field Konig with the FINEST Japanese-Made ( Can't say who, but the "XL" designation is a big clue) multi-coated lenses available, on the Planet today !!"

    This seller has a stellar reputation on Ebay...just curious any pros and cons about Konigs...compared to Plossls.

    I guess I'm more curious about user experiences with them as opposed to Plossl EP's. I did a search about Konigs here and many recommend them. I just want to know more.

    Thanks! Great find. I am going to order 2 of these in 2in. format...with my Zhumell 30mm, I think a 19mm and 13mm will fit nicely...combined with 2in 2x Zhumell barlow, I should be set for awhile.

    Chief - I'm also waiting for 2 of these to show up the 1.25/2.0" 6.7 (70deg) and the 2" 16mm (80deg)... what has changed with the Russell Konig is that even in 05' and until recently these were mainly narrow field ep's - I've heard folks compare these to PXW's at a fraction of the cost. I need to know if that is true especially if same or better transmission and other character as my PXW5 is a planet/planetary killer in my refractors when seeing holds.

    Amazing that he claims they will work equally in any scope from f3.8 to f20!! But I see that a few are 6 element instead of 3, so are they split/composite to for similar grouping to keep the type desig as Konig?

    Lets keep this thread alive? would be interested in hearing what you think, may be a while for me as here in PNW the weather and seeing just terrible lately.

    These arrived a few days ago, but with an 8 week old baby girl and the overcast skies, it has been a challenge to test these out. I viewed for a bit with my 8SE for about an hour and they were pretty crisp. I haven't had them in the Z10 yet. Maybe tonight...we have some cirrus clouds rolling in ahead of an ice storm that is supposed to hit us in a few days so I'm sure the seeing will not be ideal. I will update you as soon as I get an ideal night.

    Wow...that new 6.7 mm looks interesting...kind of like a hyperion style with 1.25-2in option. Also, an 80 deg FOV...nice.

    With this terrible seemingly unending cloud cover I'm chomping at the bit to try out the

    6.7mm/70*, 16mm/80*, 19mm/70*

    If I like the 6.7mm enough and it works as advertised I may put up my P7XW ! But I need to see something besides clouds for at least 2 nights to do a good critical comparison.

    Chief, any luck over there where you are?
