In reply to fibonacci moose:
> Wow - thanks for the responses. I will look at scopes as well then. Assuming they fit on a regular photography tripod, which I have? Actually, there is a balcony so it won't just be looking though the windows, although I will probably do that too. I was more attracted by the binoculars, since I can just stick them on a shelf when not in use rather than have tripod etc. kicking around.
Do it, a friend of ours also has a house with the sitting room window overlooking a small valley, and with the spotting scope next to the windows he can look at the birds in the garden as well as in the woods at the other side. No comparison to binoculars.
> Do binoculars come with tripod mounts?
Only the very largest sizes, there are e.g. cheapo Russian 25x65 binoculars that even have a central stabilizing rod. Otherwise there should be marine binoculars with tripod mounts, but that is outside my expertise.
> If I went with a scope, would they be suitable for both day and basic night sky use? At what specs?
Yes, looking at the night sky with a spotting scope is great. Not astronomy level, but much better than binoculars. Jupiter becomes vaguely banded rather than a whitish blob (with 20-60x zoom oculars at full mag), and the comet last year was just amazing. Also, most spotting scopes have a tilted ocular, so looking up becomes much easier.
I would go for a 65mm front aperture (much cheaper than the next class up, 80-85mm) and a 25 or 30 x wide angle, fixed magnification ocular rather than a zoom. Opticron has a few on offer, I think in the 200-300 pound range new, but there are other manufacturers as well. Unfortunately I would be better placed to comment if you were looking for a pro birdwatcher´s scope. Best go to a shop with a used gear section and have a look. It is definitely better to buy a higher spec scope (especially the glass coating) used rather than a new, lower spec one.
