I’ve already posted several videos of some of the telescopes at Chabot Science Center. Whenever I’m in Northern California, I like to visit this place, located in the hills above Oakland. What’s nice about Chabot, is that not only do they have nice telescopes -like Leah, and Rachel; but that they also let you look through them (sorry, Einstein’s personal telescope is on display only, and remains behind glass).
On Friday and Saturday nights they stay open until 10 pm, allowing visitors to look through these two classics, as well as a newer, high-tech monster named “Nellie.” Usually several smaller, portable telescopes are brought out as well.
If you can’t make it at night, they usually have the telescopes open during the daylight hours as well, and yes, you can view many astronomical objects during the day.
In addition, they also have a telescope making class and laboratory. You can sign up, purchase a slab of Pyrex glass from them (up to 12 inches in diameter) and grind it yourself in their lab. When finished, they have instruments to check it for accuracy. Mirror grinding is a long, drawn out process that may take weeks, so signing up isn’t recommended unless you live in the local area.
