I haven't looked through a bino head either as I'm using the so called giant binoculars mounted to an old friction head/mount & a newer, but older model Bogen, fluid head/mount.
I don't have a telescope and these binoculars, one 25x100 & the other 20 or 40x100, are nice for star clusters, Jupiter & the four familiar moons as they continue to move away along w/terrestrial subjects.
The 40X is nice in bright sunlight especially on birds that aren't flying, but due to truncated pupils I guesstamate that I might be seeing 2mm of the 2.5 available. The 20x shows a real clean/vivid pic that enables me to follow fast flying birds, but doesn't have quite the "wow" effect of 40X even though combining 40X panning on a fast moving bird does give up some detail.
The used 25x100 Apogee I lucked into as I knew nothing much about the larger binoculars and this one arrived collimated w/nice round EP. It comes close to resolving as much as the 40X. It'll still be edged out and cannot separate bodies quite as well, however in looking at Pleiades star cluster the Apogee view @ 25X is much more enjoyable than the Barska @ 20X.
Since the Barska has exchangeable eyepieces I marked the one 20 & 40 that worked the best w/right side as that is my best eye. It took a while to figure that out & the right side resolves better than the left.
Besides being nice that this budget astro/long distance bin has 20x & 40x is the 45* turrets. A much more comfortable view. Also, I can place the shorter 40x in the left side & the longer 20x in the right side and alternate as a double power spotting scope, but the true binocular view w/100mm for each eye is a very relaxed view.
Still, I'd like to have the next step up, using 1.25" standard, where I could buy better quality eyepieces. Garrett offers a giant binocular in your choice of two different magnification w/highest being 28X I believe, I would be tempted to pick up a used one if nothing else to compare the view.
However, even though the Apogee circa 2003 is optically cleaner than the Barska it still has one side that resolves better than the other. Both are great in the daylight if CA doesn't bother you & they're acceptable for viewing close space objects. The tripod & the head they mount on makes a world of difference. Moving off the old deck & on the yard helps w/vibration on 40X.
Anywho, 20/25/40x100 will not provide the sweeping view of a wide angle 7x35, but it's not designed for such. And you have to have them on a tripod, so moving them around can be cumbersome. They're good for looking at the moon/close up of clusters, birds perched in trees from 70' to 100yds or so, on the wing riding the wind or soaring.
They are a little more expensive than a modest set of bins, but buying used I have less than a grand in the two bins & tripods combined. Good luck in your search.
