Misaligned Pentax 20x60 PCF WP II ?

Sorry to hear about the condition of your first pair of Pentax 20x60. B&H should make this right--and I am sure they will. Please keep us posted.

There is quite a bit of CA when looking at Jupiter. A surprising amount, in fact. So far I'm not able to resolve the bands with this bino. The view of the moon was spectacularly sharp, though. Much more crisp than my Zhumell 25x100. My 12YO was particularly impressed by that view.
Bright stars are flaring quite a bit. I think I need a new eyeglasses prescription...it's been a couple of years and the astigmatism in my right eye has become worse than the current correction. So it's hard for me to say how much is the bino vs. my eyes. Faint stars are looking pretty good though.

Do yourself a favor and get your eyeglasses updated.

I rcved a pair of the Pentax 20x60s from Adorama a couple days ago, and see no double image whatsoever on Jupiter, or Saturn. Wobbly because no tripod, but tack sharp, perfectly merged images.
My eyes are slightly and differently near-sighted, but no astigmatisms (yet).

By the way, yesterday I stumbled on this review of the 20x60 PCF WP II by EdZ. I thought I should link to it here since it answers the original question I had about overlapping images at MFD on this binocular quite clearly. I'll quote the most relevant excerpt:
"The barrel images do not overlap at close focus, but almost no binoculars do. This has more to do with close focus than anything else and really has nothing to do with small exit pupil or collimation. Typical 20x binoculars, regardless of what is posted as close focus, have a real closest usable focus of about 75 ft. (20m). They will show the field circles of the barrels will not completely overlap at least out to 200 feet (60m). This is common to most binoculars, and especially prominent in higher powered binocs."
