A heavenly view from 1.5km up and above 1/4 of the Earth's atmosphere
Humans can breath without assistance up to about 6km above the earths surface, so to put this in perspective, Eagleview is therefore above about one quarter of this
layer, or one quarter of Earths breathable atmosphere! Ok, so what does this mean for astronomical observations?..well, basically, having to peer up through less
atmosphere above and particularly less of the densest lower air layers, means the views from Eagleview are somewhat sharper, steadier and clearer than those from
lower altitudes and this is quantitatively measurable. Prevailing conditions see 1.4" - 2.0" seeing on 90% of nights, placing it on par with Siding Spring, the
location of Australia's premier professional Observatory, in the Warrumbungle mountains of northern NSW.
Here is a two year graphical summary of the seeing conditions at Eagleview Observatory:
This level of atmospheric steadiness allows high resolution image captures like the following, with just a 12" Fast Newtonian:

Here is a paper that explores improvement in seeing with altitude:
