28mm Pretoria "coma" corrected eyepiece

[Merlin66 (Ken)]

I aquired this 2" eyepiece last year, before selling the 18" f4.5 dobbie; used it only once to check it out.
A couple of slight, small irregularities on the coatings, which no way affect the impressive imaging. As received from the States, the eyelens group appears loose in the assembly, haven't seriously tried to strip and adjust as once again it doesn't impact on performance. External Body in excellent condition, no cosmetic marks.
This is THE eyepiece for use with fast reflectors and designed by Klee to correct coma and give flat field with f4 systems. Paid us$ 160 in June.
I'll never use it with the gear I have now; open to all offers.
I can prepare photos if need be.

recieved ken .. the upper group sure needs a clean and a good look ..against a 27 pano as it stands I think this eyepiece is better to look through overall.. sharper on edge by a long shot .

yup graham, unlike panos and the like this EP is designed for fast scopes like yours.

Had a look today ..found the locking ring of the eyelens group was a little loose ken .. snug and aligned now .. even better 80 % of the
coating irregularitys I see were drop ins of dust ect that had squeezed under the loose eyelens and worked its way down maybe ?.
cleaned and looking good now .
While I could have a shot at the top group and take care of the other 20% as well to really clean things up its all looking pretty close to great atm .. so I cant see the need to really bother as theres not much there .. and theres a good chance I'd cock a lens deep in the upper body so I'll quit while i'm ahead..many thanks for this bargain

Ving what I have read about this pair is both work well in fast scopes
To be honest there isn't a lot between them IMO ,but from my look so far the pretoria is 'just' a little nicer to look through than the pano .
which kills considering the price differance I paid between the two !!


SOLD it is .
