As most of us, I face the problem of looking for objects near the zenith, yesterday was impossible for me to look for Cocoon Nebula. I even got some kind of motion sickness (perhaps it's not the correct word, sorry for my English) due to the position of the neck since my sky is contaminated and I started at Deneb and it was realy high. So I thought about the possibility of attaching a webcam (I would need to buy one) to the finderscope so I can display its output on a laptop or tablet. I don't want to use it as a guidesope.
Have any of you tried it? Do you loose much of the field? What magnitude are you able to see? My finderscope is a 7x50.
