The AOE's better coatings decrease reflections (increase contrast).
Potentially important spec info for the Andrews model is not shown- notably eye relief and field of view.
re: zoom binoculars
Zoom models are not recommended for those primarily interested viewing the night sky.
Fixed-power binoculars (up to 20x) offer up to a 50% wider view than zoom binoculars set to the same magnification.
Decreased optical precision due to the difficulty of keeping the zoom elements in each eyepiece in perfect syncronization, and difficulty to handhold at higher magnification are other disadvantages.
