On paper, the Nikon 16 x 50 "Action Extreme ATB" binocs have a reasonable afov (56 degrees) and nearly 18mm of eye relief. Does anyone have experience with them for astro use? Can you share any impressions? Thanks...

I would expect it to have smaller fov by 6%-7%, same as the other two 50 Action EX ATB. However , both do measure up very close to the speced eye relief. Only the 7x50 and 12x50 have a field flattener lens, so I would expect this one to have good filed sharpness out to only 60% of fov.
