50mm objective lens is superior in dark environments compared to 42mm. Astronomers prefer them for a reason
I would imagine bigger then 50mm would be even better
I own the maven 6x30 and Kowa 6.5x32. They are quite different and depends what you are looking for in a binocular. But if it’s for astronomy then the Kowa wins hands down. I can pick up the North American nebula way better in the Kowa
but here is my findings
Mavens
1. smaller form...
Been down this road many times
what I did learn is that one eye viewing of a spotting scope was not for me and most of the time the magnification was between 20-30x And I only looked out to 1-2 miles tops!
At that point 15x covers that range well, more pleasing to view, and brighter due to...
I use the fixed magnification eyepieces, they are near alpha glass quality. At least the sample I have.
the 20x eyepiece is brighter and more comfortable
16x eyepiece is even better, but at that point I rather have 15x binoculars
Like I said, it has a excellent reputation for a reason
Nikon ED50 from a Japanese retailer or Amazon Japan is dirt cheap and the glass is nothing short of amazing
it has a long running reputation for a reason
I like my mountain rifles light!
a 1 ounce red dot is sufficient for me, especially since most hunts are under 100 yards in the mountains of the east coast
For me, the more the better. No such thing as too much ….the only limitations is that some optics tend to have distortion in the outer edges with super wide FOV
I prefer zero magnification (red dots) so it’s less of an issue
