theres nothing like the 6 degree odd view that you can get from a pair of binos. Nothing will dry a young mans desire faster than looking at blurry images or dull images. You will see alot of open clusters, Omega centuri, 47 tuc Jewell box, saturn, jupiter, and the moon is spectacular all of these or even some have been the catalyst to our life long hobbies.! I know i have said it but if you boy is interested enough to look up im sure he will find a way to wrap his little hands and fingers around a pair of binos.
My boy is only 4 1/2 and hell he is a nutcase

will stand out with me in the freezing cold just to look though the eye piece and mind you his eyes are like a eagle and being young he can see alot more than i can. I can see that for his 8th birthday/christmas ill have to buy him something like what i have now.
I belive that its all down to how you go about introducing things to him. If you know what your talking about well, then you can answer his questions in a way that he will understand, show him what you do, how to do it and when and foster his growing desire to look sit down and plan your nights viewing, or look into the coming months! you will have a astronut before you know it! This is how i have done it and the results speak for themself.!
