The images were taken with a device that Doug Duncan invented to capture eclipses with a smartphone

Doug Duncan, an emeritus faculty member in the Department of Astrophysical and Planetary Sciences at the 麻豆影院 and the former director of the Fiske Planetarium, was recently among a select few recognized by the International Astronomical Union for their photos of the heavens.

The IAU鈥檚 Office of Astronomy for Education awarded prizes to about 30 people worldwide, including Duncan. The IAU said it selected the winners after receiving nearly 430 entries from 40 countries and territories worldwide for its third-annual astrophotography contest, which was judged by an international panel of astrophotographers and astronomy teachers.

鈥淭he images of the sky captured by enthusiast stargazers can leave one in awe, but they can also be important teaching tools,鈥� the IAU notes. It adds that the organization 鈥渟ought out images of the motions of the heavens: from the Sun鈥檚 path across the sky through the year to the movement of the stars in the night sky and the changing phases of Venus.鈥�

Duncan received an honorable mention award for his photos of a solar eclipse, taken with his smartphone. Images taken with smartphones or other mobile devices was one of five IAU photo award categories.

Under normal circumstances, attempting to capture a solar eclipse with an unaided smartphone camera is a very bad idea, Duncan says, noting the sun鈥檚 rays can harm a smartphone internal workings in the same way that looking at the sun for extended periods can damage people鈥檚 retinas.

However, that was not an issue for Duncan, thanks to his use of the 鈥攁 product he designed to safely capture photos of solar eclipses with a special eclipse-viewing lens that attaches to the smartphone鈥檚 camera lens and software that controls a camera鈥檚 zoom, focus and exposure. After about two years in research and development by Duncan, the Solar Snap is marketed by Bartlett, Tennessee-based American Paper Optics, which he says has sold about 50,000 Solar Snaps.

As for winning the astrophography award from the IAU, Duncan says, 鈥淚t was a nice to be recognized. I鈥檓 particularly happy for the recognition it brings to the Solar Snap, which is the first invention I followed from the idea through completion. And people who use it are quite happy with it, so that makes me feel good.鈥�

Duncan adds that he is just as happy that one of winning photos in the smartphones categories was taken by a participant in a CU Alumni Association Roaming Buffaloes trip that he organized last year to view the northern lights. Duncan said he was happy to give some photo tips to Jason Johnson, who won an IAU award for his photo "Northern Lights Color."

Meanwhile, Duncan is gearing up for his next Roaming Buffaloes trip, to witness a full eclipse next month in Texas, an event he is calling 鈥淭otality Over Texas.鈥�

And after that?

鈥淲ell, I was thinking of retiring,鈥� he says with a chuckle. 鈥淏ut the next total eclipse I鈥檓 focused on is in the summer of 2026 in Spain, pretty close to Barcelona and Valencia. And if an eclipse is happening in a really beautiful place, that鈥檚 when I鈥檓 very tempted to go.鈥�
