I propose a new category of "Sorta gimmicky, but so much fun ya gotta have one".
    Well I can live with that.... Guilty as charged!

    Hello all,

    finally the weather has allowed to take digiscoping pics through these Leica B32x and B20x eyepieces on the 6" F/5 Synta Sky-Watcher achromatic refractor.
    Here is the comparison,

    Leica B32x vs B20x comparison .jpg

    The houses are close to 1km away, down in the valley.
    The smallest details seen and recorded with the Lumix GF7 held on the eyepiece are the wires (3.5mm diameter)* in the fence, seen under the angle of 0.72", and that's close to the Dave's limit of 116/D(mm)=0.77"

    )* Assuming, they have used the same 3.5mm wire as we did, and assuming I can still do the simple trigonometry on my Texas pocket calculator.

    The captured pics reveal some CA, not visually noticed at the EPs. This may be due to the mismatch of the Lumix optics with the Leica B series eyepieces.

    So, these test results are as expected.

    Thanks for looking and reading,

    JG
