Andddddd.........you're looking at maybe 30', how about 200'?
Dude, that is the issue. Focal length........
What looks OK at 30' is tiny at 200', what looks good at 200' goes off screen quick or is so small as to be worthless info.
Thus......multiple questions about this.

Frankly, maybe $20US for mirrors is likely the best bet for now.......
