Trips about Observatory


Palomar Observatory

The Hale/P200 Telescope

Being an astronomer is a lot of fun - especially when we get to do observations. I finally got to do my first observing run at Palomar last night (although I was just helping out - just a bit). For those who don't know what it's like, essentially you spend the night finding targets using a guide camera, and then taking exposures that will theoretically tell you something. We were able to observe from about 8:30 PM till about 5:30 AM, which meant I got to see sunset and sunrise from the top of the mountain.

When not observing, observers stay at the "Monastery" - the lodge for visiting observers. It was a lot of fun, and I'm hoping to get observation time again next semester, so this should hopefully be a semi-regular sort of thing for me.

I took some time to take plenty of photographs. To explain the P16/48/200 references, they refer to the diameter of the mirror in the telescope (in inches). The P48 is a wide-field telescope, the P60 (which I don't think I have any photos of) is primarily used to measure how much light (photometric), and the P200 (the one I was observing on) which is primarily used for spectra. The P200 (also called the Hale telescope) is the 19th largest currently constructed telescope in the world.

Kitt Peak 4m at Sunset

I was invited to join an observing run at the MDM Observatory on Kitt Peak, and so got to spend a week in Arizona (1 night in Tucson, 4 nights at MDM, and then another 2 nights in Tucson). The first day I got the opportunity to look around the Steward Mirror Lab and see the mirrors currently being worked on for LSST and GMT. Then, we headed up to Kitt Peak, where we got to experience a fun storm the first night (including losing power) and eventually got to observe two out of our four nights. When not observing, the Kitt Peak National Observatory was a cool place to explore, and the views and sunsets from the top of the mountain were amazing.
