Hi Susan,
Binoculars are a great starting point in visual astronomy. I would recommend something in the size of 8x42 fully multicoated lens.
Try Andrew Communications (Greystanes) as a starting point.
They've got a pair of 8x42 triple multicoated, however they're going for $169. Something cheaper maybe a pair of 8x40 @ $79.
I bought a pair for my boy when he was 8 last yr (8x42) for bird watching ($89) and they're brilliant for the price.
I've bought a few things from there and the service is very good. Give them a ring and see what they may have on offer/special.
Things to consider are:
- weight
- how comfortable are they to hold at upright position for short periods
of time
- robustness - knowing kids, they'll bump, knock them around no matter
how many times you tell them to be careful.
Be careful of anything too big, weight will be a deterrant. But whatever you choose your boy is going to have a blast and if cared for will last a lifetime.
Cheers Norm
