Danger - black hole where not even eyepieces can escape

Dangerous hole!

I realized once this was installed that I had a very dangerous situation that could result in a very difficult retrieval.  The hole at the top of the pier could easily attract and suck in telescope mounting nuts, eyepieces, evening observing snacks, cell phones...or anything that fits in an 8x8 inch opening!

Safely covered

Fixed that problem with some scrap and covered up that danger.  Later I did paint this black.
