RCOS Carbon Truss 20 inch Ritchey-Chrétien Telescopes...
Use an RCOS 20RC at NOAO's Kitt Peak National Observatory (RCOS 20" f/8.2 with ION Milled optics shown).
"High atop Kitt Peak sits the largest collection of optical research telescopes anywhere in the world. Each evening, we offer a public program like no other. At our Visitor Center and its multiple observatories, the public is invited to learn about and gain hands-on experience with the latest astronomy has to offer. We’ll view everything from planets to distant galaxies using our 20-inch and 16-inch Ritchey-Chrétien telescopes from RC Optical Systems.
If you’ve only just found out about the Nightly Observing Program, please consider joining the nearly 7000 people each year who experience the thrill of an evening on Kitt Peak. Discovery and excitement await!
Due to the popularity of this program, it is recommended that you make reservations 2 to 4 weeks prior to your visit.
This program is an introductory star-gazing program. Those looking for a more in-depth experience can reserve a night on the Advanced Observing Program."
