Tom Masterson

Director of Telescope Operations

Tom's fondness for astronomy started at a young age while watching Carl Sagan's "Cosmos" with his family. After receiving his first telescope as a gift from his loving family in 2013, he caught the astrophotography and amateur astronomy bug in full force. Tom's images have been published around the internet and in print, most notably on NASA's Astronomy Picture of the Day (APOD), BBC Sky at Night, Universe Today, museum exhibits, print calendars, and others. He is also the Mountain Operations Manager at Mount Wilson Observatory, located in the mountains above Los Angeles, California.

Serving as the Director of Telescope Operations at Grand Mesa Observatory, Tom focuses on making sure the observatory is operational and functional so we can continue to offer world-class telescope systems for research and astrophotography. He is dedicated to our mission of increasing education, awareness, and understanding of the cosmos for all who are involved with Grand Mesa Observatory, and for the general public who may come across our images or astronomical research.

When not under the stars or staring at a computer screen processing astrophotos, Tom enjoys spending time with his Maine Coon cat, Karl, making sure he gets all the pets, brushes, and treats (within reason) he needs. He also likes listening to music, going to concerts, occasionally DJing, surfing, snowboarding, ceramics, and reading/watching science fiction. You can find out more about Tom and take a look at his images on his website: transientastronomer.com.

Catherine Whiting

Head Science and Research Astronomer

 
 

Garrison Turner is a Lecturer of Physics at Colorado Mesa University. His interest in astronomy started as a child living in Indiana. On clear nights, the glistening stars were simply captivating. This led to a life-long passion which led to pursuing education and a career in physics and astronomy. Having attended Ball State University for his B.S. And M.S. In physics, he spent four years learning photometry with applications to binary stars, pulsating variables, and exoplanets. After graduation, he started his teaching career in physics at various institutions in Kentucky 2013. In 2017, he started work toward his Ph.D. in physics and became a candidate in 2021 through the University of Louisville. His dissertation is focused on variable stars, including pulsating variables, eclipsing binaries. Other research interests include exoplanets, optimizing photometric techniques, and camera characterization for astronomical applications. In 2023, he was welcomed by Colorado Mesa University as a visiting instructor, where being under the dark skies of western Colorado reignited a passion for astrophotography. Invited back as a visiting instructor again for the fall of 2025, he was then offered the position of Lecturer. In the spring of '26, Garrison was appointed as the Assistant Director of the Grand Mesa Observatory. In addition to teaching and research, Garrison is an avid hiker, frequenting hikes at 12,000 ft and above in Colorado's high country, as well as a hobbyist musician and landscape photographer. 

Catherine's passion for astronomy started from stargazing at a very young age, developing into a fascination of black holes and cosmology in middle school.  She then pursued astronomy and physics for a career.  As a student at the University of Iowa she studied magnetic fields in the universe using radio waves until receiving an M.S. in astronomy.  Along the way, she did Research Experiences for Undergraduates (REUs) at the National Radio Astronomy Observatory's Very Large Array and the Institute for Astronomy at the University of Hawaii.  After taking a General Relativity course in graduate school, she fell under the spell of theoretical physics and received a Ph.D. in string theory.  Continuing this adventure as a postdoctoral fellow at the University of the Witwatersrand in South Africa, she realized that teaching and education is incredibly important in this world and an area in which she could have a true impact and returned to the U.S. with that goal in mind.  One of the reasons she came to Colorado Mesa University as a professor was to return to her initial passion for astronomy.  The unique connection between the Grand Mesa Observatory, the Air Force Academy's Falcon Telescope Network, and Colorado Mesa University was what drew her to the area, and of course the amazingly gorgeous scenery of Western Colorado.  She now uses the Grand Mesa Observatory's telescopes with her students to help discover exoplanets and measure their properties.  Her other addictions include, but are not limited to CrossFit, cooking, trail running, crafting cocktails, and dog petting.

Founders' Remarks:

The idea that led to the founding of the GMO resulted from a conversation between me (John Mansur) and my astronomy mentor (Terry Hancock) sometime in late 2016.  Terry was living in Michigan where his evening star gazing was seriously hampered by poor Michigan weather.  I was, and still am, in Florida, with warmer weather but still poor astronomy conditions.  I mentioned to Terry that I wished I had a remote-controlled observatory on our place in Colorado where you can see the Milky Way every night, and there is no light pollution.  Terry said that such an observatory would be a dream come true for him also.  The discussion continued for a few weeks, growing in size with every conversation, until we came to the conclusion that what was really needed was a roll-off observatory with at least six piers for telescopes.  I mentioned that there was no way to do this without a full-time operator to run such a project, and Terry volunteered that he would jump as such an opportunity.

I raised the possibility with Vicki (my long-suffering wife) who only rolled her eyes a little bit at the idea.  I campaigned on the idea that we would be bringing a unique capability to Western Colorado of a state-of-the-art observatory and it would be a great educational opportunity for the young people of the area.  She was intrigued partly because it would give an opportunity to continue the legacy of service to Western Colorado left by her parents, Howard and Nina Brouse, who had been the owners of the ranch where the observatory would be established.  While running an active cattle ranch, they had served the local community and the county for decades as 4H leaders and Colorado Cattlemen’s Association members.  They also helped found the Mesa County Historical Society.

With Vicki’s blessing, Terry and I agreed that he would move to the ranch and supervise the construction of our dream facility.  Vicki and I decided that we needed a house along with the observatory for the “lighthouse keeper” (Terry) to live in, so that was added to the project as well.

We consulted with Vicki’s nephew, Quint Shear, a prominent Grand Junction businessman for advice on who would be a good builder to take on our project, and he suggested Greg Toft, of Canyon Creek Builders.  I spoke with Greg, and in the spring of 2016 Greg came on board, Terry packed up his van, his cat, Twink, and set out for Colorado.  Thus, the Grand Mesa Observatory project was born.

About this time, I contacted the Physics Department of Colorado Mesa University and told them what we were planning.  Soon after I was called by Dr Jared Workman of CMU, who was excited about our project and shared with me that he had been working with the USAF Academy Falcon Telescope Network (FTN) Project for several years trying to get a proper location to establish a site for an FTN telescope for CMU. That discussion continued while construction of the house and observatory began.  Even though Terry and I had a target in our mind of being operational by about February 2017, we finally had our grand opening in July, and the GMO was truly operational. 

We now have five telescopes operating, a sixth coming on board in a few months. On October 1, we were approved as a 501.c.3 non-profit organization.   And we are pleased that, after working closely with Dr Workman for several months, we signed an agreement with CMU, effective December 1 2017, to build an observatory adjacent to the existing roll-off observatory to house an USAF FTN 20” telescope which will be one of only 12 FTN telescopes located around the world!

We are so thankful to all the people who have volunteered so much to make this dream a reality, especially Lora and Dennis Wynn - our neighbors who have helped with literally everything, the whole Purdy Mesa community, Nancy McGuire (who has not only been a great help, but is now engaged to Terry- yea!), Isaac Garfinkle (who even moved next door to be close to the GMO), and Dr Jared Workman.

 

Exciting times and clear skies ahead,

John and Vicki Mansur
