Welcome to IIS Blu Moon!
I suppose you are referring to the 15x70 Skymaster.
You are probably better off with a pair of 15x70 from
AOE. These binos are fully multicoated (and the coatings are good!) as opposed to the Skymasters which are multicoated, so you'll probably get better contrast with the AOEs. (If you want to lash out you might go for the new AOE MX Ultra 15x70. This is the same bino as the new Astro-Physics 15x70.)
Like others have said if you don't have a good pair of lower power binos get one of these first for handheld use. Something in the range of 7-10x50. (a 15x will need a mount - mounting binos for looking up high above the horizon is tricky)
