The main reason we went to Tucson was to participate in the Night Observing Program at Kitt Peak National Observatory, and I highly recommend it.
Kitt Peak is 56 miles southwest of Tucson. Allow 90 minutes to get there from Tucson. It houses 26 different telescopes, which makes it the world’s largest collection. It is open during the day for tours, (guided tours are $4 each, or you can go on a self-guided tour), but if you want a chance to look at objects in the sky with a knowledgeable astronomer through a more powerful telescope than you’ve ever had, take advantage of the Night Observing Program.
You must make a reservation for the NOP, at least 2-4 weeks ahead of time. On the day of your visit, you’ll be called with a time to arrive, which is about 1 hour before sunset. They will also tell you the predicted weather conditions at that time. If the forecast is for cloudy conditions, you’ll be given the option of canceling or participating in the program at a discounted rate. The day we were scheduled to go, we were told there was a 5% chance of clouds that night, and we were given the option of canceling. We decided to stick with it, and when we checked in we were charged the discounted rate ($30 per person instead of $39). It turned out to be a very clear night – a few clouds here and there, but we could see everything very well. I really appreciated that they stuck with the discount even though the sky was so clear.
After checking in, you have some time to look around on your own and you are given a boxed dinner (sandwich, chips, bottle of water, apple, granola bar and cookies for us). They call this a “light meal” but it was more than I could eat! Because it was such a nice evening, everyone decided to eat outside at picnic tables. After dinner, you’re called in to the Visitor Center for an introduction to the evening, and then you’re off to the west side of the mountain to watch the sunset. Beautiful!
Then it was back into the Visitor Center for an introduction to using a star chart (a planisphere) to find things in the sky, an explanation of some of the things we’d see and of the distances in space. With our star charts, powerful binoculars, and small red flashlights (you can’t use any white light on the mountain after sunset or you could mess up the observing done by the scientists that are there), we headed outside. Our guides had very powerful laser pointers that stretched far into the sky, so we were easily able to follow what they were pointing at. We looked at several constellations, stars and nebulae and were amazed at how much we could see just with the binocular.
Back inside for another briefing, and then the group of about 25 split into 2 groups to go into the two visitor center domes to view the night sky through their telescopes. This part lasted much longer than I thought it would from the description, which I was very happy about! We viewed 6 different objects ranging from the moon, to the Orion Nebula to a spiral galaxy that is 35 lightyears away. The guide gets it all set up and then each person gets a chance to go up to the telescope and view for themselves. Everybody walked away saying “Wow, “Amazing,” “Awesome.”
The whole program lasts about 3 to 3.5 hours. Before you leave, they’ll give you a printout of the objects you saw that night. When you get back home, you can go on their website and see other pictures of those objects. One of the more interesting experiences of the night is leaving the mountain. Remember that white lights cannot be used on the mountain when observing is going on, so that means driving the first mile down the mountain without your headlights! It sounded scary, but one of the guides leads you for that first mile, and everyone goes very slowly, so it’s not at bad as it sounds.
You’ll be told this over and over, but do heed the advice to dress warm – or at least to bring layers. It was 90 degrees in Tucson on the day we did the NOP. By the end of the night on the mountain, it was probably about 40 degrees, and you are outside most of the time. We had jeans, sweatshirts and winter coats and were very comfortable.
