Well, after using them both a while, here's my thoughts.
Comparing the WM 7x50 w/ compass
to the Nikon Action 10x50, here's my thoughts:
I prefer the Nikons lack of compass
for star gazing, actually makes a big difference.
The Nikon takes more effort to focus, I rarely touch the focus on the 7x50
Not much difference for star gazing, no issue with holding the nikons, I usually go for them unless I need the compass or conditions are rougher.
I'd probably try going with a larger binocular if I ever get the chance.
