    Default Williams Optics Binoviewer: eyepieces?

    Hi bino-people,

    I have been using WO binos for around 12-15 months. The package came with included 1.6x corrector, and a pair of WO 20mm 66deg oculars. Using the unit with a 14" f5.1 Dob. I had to reduce distance between primary, and secondary mirrors by around 2" to get sufficient infocus. Now all is sweet. Lunar, Planetary and DSOs, (Globs, Nebula,(M42 etc)) views, have been greatly enhanced through the two eyed images.

    Wanted a bit more magnification with the upcoming oppositions of Mars and Saturn, so invested in a pair of GSO 15mm 70deg Superview eyepieces. Tried them out a few nights back, on moon and Jupiter, and though seeing was only fair, I have to say I was quite impressed with the performance of these oculars.

    I am interested to hear from others about alternative eyepiece combinations others have/are using with WO binos. What works well, and what dosent.

    The only way to observe in my book is with a bino-viewer. I have been observing with bino-viewers for over 10yrs. I do not have the WO bino, but for observing the planets I use Orthoscopics and Monocentrics eyepieces with my bino-viewers.
    The reason I use Orthos and Monocentics, is do to the on-axis sharpness and the high gain in contrast that these designs have over most other optical designs. I use my 6" refractors for observing the planets. I also use a 2" bino-viewer for deep sky objects. When my 8" refractor gets here, it will be the main bino-viewer scope in the observatory.
