This is exactly why when showing someone stuff at the telescope, we should be saying to them something like this....
"These are called faint fuzzies for a reason, just think that light took 30 million years (or whatever) to get here, there was no life on the planet then. What we can manage to see out of this will be most amazing. Now take a good hard look and see what you can make out."
The above in my opinion will get them more excited and they will feel more rewarded.
Now, as for planets, I have no tolerance for people at the scope that can't appreciate Jupiter or Saturn. Tell me you don't see anything and you'll either get abused if you're bigger than I (more likely as I'm a featherweight) or get a fat lip.
Aged people excused. Esp. if you're an aged person that doesn't know we reside in the Milky Way galaxy (yes that's you Mum)
