Sorry Simon, we should have moved to a new thread earlier. The forum software isn't fond of really
long threads. If you go to "My Home" and then "Display preferences, number of shown threads, languages, colors..." you can change the number of posts to display per page. Reduce that from 20 to 19 and the thread will be over a 100 pages long for you.
The Swift 804ED does show very vivid colors, planetmalc. With my sample under the stars the image quality begins to noticeably fall off about half way from the center of the FOV to the edge and near the edge it is very poor. By day the `sweet spot' seems to be larger. At least the degradation increases gradually which I find less annoying than when things go from good to poor very quickly. It would be better still if almost all (or indeed all) of the FOV was great but I guess not every binocular can be a Fujinon FMT, Nikon Prostar or SE, etc. The 8.5x44 and 10x50 versions of the Swift are pretty similar in size (see attached picture) and weight and I agree that the objectives should have been recessed a little more for better protection.
