I still don't know how you aim the 8X50 at a not so bright star, especially if there are other similar stars around. I like the cheap rifle scope red dot finders because, while not as cool looking as other ones, it's usually pretty easy to find a plastic or card board roll, and with a scissors and tape make a dewshield that easily covers them.
My last resort for very dewy nights, is a 12 Volt hairdryer I bought years ago, which I plug into a battery pack.
As for Mars, if you can't see features on it - stare hard. Then try a pair of sunglasses, preferably with some red or yellow in them, rather than bluish ones.
Cheers,
Renato

Or the other solution for a finder is an old stubby holde. Just rip the bottom out of it and it fits over the finder. If a bit loose a big rubber band holds it in place.
