Son: I want to see the rings of Saturn
Dad: Here's a pair of 10x50s
I've been involved in outreach with kids for years. To them (and most adults really), astronomy means using an actual telescope. On the bright stuff initially, then possibly something a little more challenging. 10x power doesn't cut it on the vast majority of targets.
I had access to some excellent binoculars as a kid and looked at the stars through them from a young age, but it took a look at Jupiter through a proper telescope to really kick off my astro 'journey'. I came to fully appreciate binoculars for astronomy much later, and I keep this sequence in mind when making recommendations to (young) beginners.
