Q: 4. How many degrees does this attachment move, both vertically and horizontally?

A: I would have to say about 15 maybe 30 degrees each way total travel. I bought mine for the last super moon. Had a 1600mm lens attached to this and was easily able to track the movement of the moon. At 1600 mm I had to constantly shift both axis and it did a great job. It is not super fast, meaning the threads on the adjustments are pretty fine, so if you are trying to track birds of something moving you will have to crank pretty quickly to keep up. But if that bird lands on a branch and you zoom an and want to adjust to frame the shot properly you can easily do it with some practice.

Q: 6. I'm considering these for my Mom. She wanted some theater glasses stronger than normal. Are these too big to fit into an evening or small purse and/or do you know if they come with a cord or anything to go around the neck? Any other items you recommend I buy along with these?

A: My Mom likes hers. They are approximately 4.5 x 2.75 when opened up, and the barrels are 1.75 at their beltline. The bag they travel in is 4.5 x 6 when laid flat. I don't think there was a chain, but we got a matching brass chain. So they are very nice opera glasses, stronger than the usual glasses. One thing, we had to put a little bit of medium thread lock on the set screw to keep it from working loose--easily done. Can't think of any other accessories that would be needed.
