Thanks everyone.
It was a lot easier than I thought making the telescope.
The focuser made it a breeze because of it's 6" range of focus.
They make a 102mm???
Um, when is my birthday? (Nov

)
So far I've only been able to look a stars for 10 minutes or so at a time. It will be interesting to see what the moon looks like through it.
My lens is f11.25 from my calculations.
Does a longer focal length increase/decrease viewing performance or make no difference at all?
