I keep wonering why 7x50's continue to be pushed for astro use. Considering Alan Alder's article in the recent S&T maginfication may play as big or bigger role for night time use than objective diameter. I think we've all seen the difference between 7x50's vs 10x50's on M81 and M82 for instance. But 10x is just to much trouble to hold steady for any length of time!
I am sold on Swift Audubon's for astro use, price considered. I realize the edge is soft, but so are the edges of any other $250 + bino I've looked through. With narrower FOV no less.
Am I the only astro person using birding binos? Any one else out there? If so, why do you use them?
Or why would you use 7 x 50's instead?
