Regarding the passenger windows on aircraft, I can see the individual windows at ridiculous distances with the handheld Canon 18×50 I S. But this is at night and I must admit that I've not seen the passenger's heads, although I may have a go at this.My problem with the Takahashi 22×60 is that it is a binocular telescope rather than a binocular. They did make a telescope, which is basically one half of that binocular telescope. It is long for a binocular and I think heavy for handheld use. However, on a tripod it should be very good indeed and probably outresolves the Zeiss 20x60.In addition, I would be wary of a second hand fluorite binocular in case moisture had got into the fluorite element. If this happened the crystal could deteriorate. But I don't know if this actually happens or not.It would be much better to buy one that you can see and try first.Vixen makes very good binoculars or binocular telescopes, I think 70 mm, 81 mm and 125 mm. I think that they have about eight different focal length sets of eyepieces. And these binoculars I think can take high magnification well and remain collimated.Another alternative may be to buy the Nikon P 900 camera and use this for long distance work, either looking through the viewfinder or at the screen. It should not need such a substantial tripod. The Nikon P 610 is also good.I don't know if it is possible to fit a binocular viewer to a Swarovski spotting scope. I think I've seen maybe something like that or maybe even a Swarovski binocular telescope.To get within your price range a 80 mm ED telescope with a binocular viewer would I think work very well.The Zeiss 30x60 BGAT is within your price range and has good resolution but of course it only uses one eye.There are some very good Russian Maksutovs that are sturdy and of good optical quality and not very expensive.Two Opticron 20×50 mighty midgets mounted side-by-side are really low price and if carefully mounted should do the job.</blockquote>
