Very nice, Douglas. Many happy nights watching the night sky!

I got my first telescope at the age of about ten, and a 6" reflector
whenn I was about fourteen. It took a lot of saving up and persuading my
parents. I suspect yours may well be more robust and be a better
light-gather than mine was - it was largely home made (and no, I didn't
grind the mirror!). But what I could see through it amazed me.

I bet that your base is heavy though, but a robust base makes for better
stability in viewing, so it's a trade-poff.

Happy Christmas,

Peter
