I'll jump in here, again if I may:
While borderline insofar as premium is concerned, I must say that the
Ultima line of EPs, especially 12.5mm and 18mm, are superb EPs for the
money. I have the above two plus a 24mm, and 35mm. All are extremely
well made [Vixen], and are near equivalents to Orion's Ultrascopic
These mate [obviously] extremely well with the Ultima 2x [2.38x]
Barlow, and the 12.5mm/2x combination was the only one to date that
allowed me to resolve Io during its transit of Jupiter across the
planet's disk on October 14th/15th. I couldn't believe it myself,
until it happened in my SV80/6. Sub-1/2" seeing! In an 80mm scope at
91x! While this may be an extremely rare situation, this attests to
the quality of these EPs, and [of course!] the visual acuity of the
observer ;-) [LOL]
I must also point out that regardless of how good one's objective and
EPs are, you will never get the most out of the scope unless you treat
the entire unit as an optical SYSTEM. This includes a high-quality,
near-premium diagonal also. No sense spending all those dollaros to
cheat oneself later...
For the newer members considering EPs, take a look at my review from
cloudy nights in the files section - I have used a number of different
types of EPs and have done some comparisons in this scope...
P.S.: I sure hope that as more members get their scopes in, that
they'll be able to have decent enough weather to share their
