G'day,
Have you got a tripod to mount these binoculars on? Hand holding a 20x80 binocular steadily is a feat well beyond my abilities. Are you particularly looking for a 20x80 binocular or just something larger and higher powered than more common 10x50 and similar glasses? I'm not a fan of the Skymasters (too many ship misaligned) but if you managed to get a good one they rank highly on a `performance per dollar' measure. If you aren't stuck on a 20x80 specifically then I'd suggest looking at the BA8 15x70 which is sold under many labels, e.g., by Andrews Communications in Sydney as the "MB Ultra". Happy observing with whatever you decide to buy!
