(Zoom into these photos to see Mars!)
Taken using my Hadley 3D printed telescope, with a crowd of friends invited to watch the occultation of mars by the moon! The phone I was taking photos on ran out of battery, so I hastily threw a friend’s iphone into the holder just in time to capture these.

I have a 1/2" diameter hole. I want to put a pipe inside the hole. What size PVC pipe fits into a 1/2" hole?
