Well, I thought a pair of good binoculars might be useful on holiday for a start.
Or for quick viewing, even from the window.
I have just read this though re binoculars:
The larger the objective lens, the more light it can gather, which is important in low-light activities such as astronomy or hunting at dawn or dusk.
The same as with telescopes obviously. Unfortunately I actually think they were a bit on the small side, but I will check anyway.
