Here's the deal: We hold the event no matter what. We drink coffee, eat cookies, and I give a brief presentation about our observatory and some upcoming celestial events. We tour the observatory so you at least get to see the scopes, even if you can't see anything through them.
We also set up smaller scopes inside the Science Center. I know this sounds weird, but the hallways are really long. If you've never played with a telescope, or if you are interested in purchasing a scope it's a nice chance to see how they work.
The student astronomy club (MC Stargazers) will be available with me to answer any burning astronomical questions you may have.
To sum things up, if it's cloudy, and it looks like it's going to be cloudy tonight, we won't be able to see anything through the telescopes. I totally understand if you don't want to make the trip out tonight because of the weather.
Regardless, I look forward to meeting you tonight, or at another event. Thank you so much for your interest in astronomy and the MC Observatory!
