Lowell Observatory has a significant role in the history of astronomy here in the U.S. Not only was Pluto discovered from there, but the theory that canals existed on Mars also originated at Lowell by Lowell himself. While some may discredit Lowell for the canal claim, it did drive others to do more discovery on the planet.

We took the guided tour which was quite fascinating. I really enjoyed examining the antiquated research instruments used in the early 1900s. These instruments are on display in the rotunda museum/library, and include details on how each instrument was used. Probably the most significant instrument was the blinking machine utilized by Tombaugh to compare photographic plates in an effort to locate the planet that would later be called Pluto.


Above was Percival Lowell's first telescope given to him when he was 15 years-old. Below is what resulted when Lowell developed the illness commonly known as Aperture Fever.


The 24-inch Clark Telescope used to see the alleged canals on Mars.


While his observing chair is interesting, note the Ford wheels/tires used for rotating the dome.


The dome.


Cynde thrilled to be in the presence of such astronomical greatness. The enthusiasm on her face says it all. She later said she learned a lot from the guided tour, as did Conner (our oldest). Wish we could've stayed for an evening of viewing so that Conner could star test 24-inch achromat and checked it for color.



Love the spectrograph instrument. I really enjoyed examining the antiquated research instruments.


Clyde Tombaugh's notes on Planet X, later named Pluto.


Pluto's planetary status is a sensitive subject there at Lowell.


The Planetary Camera. Geez...he should've gone with a Lumenera SkyNyx camera instead of this overweight film plate holder.
