The last binoculars I bought are 9x63 5.0 deg TFOV 7.0mm exit pupil and 26mm eye relief. I believe this may be the highest power and aperture that are hand holdable (a little over 2 lbs). With others pointing out galaxies with lare pointers and turning them off, I am able to see galaxies such as the Whirl Pool, M81 and M82, etc. However, it will take some time for me to find these on my own.
I like the so much weight wise, that I am tempted to try out the 15x63mm version too; although these will most likely require a monopod to keep steady at 15x.
I do like to lie on my back and look up near the zenith; and you can do this for a long time with these light weight binoculars. When I tried with 25x100 10 lbs binos after 2 minutes, I feared I might get two black eyes. ;)
