Dean Regas

Dean's List

Moon + Venus Conjunction

The slimmest crescent Moon was about 1 degree from the planet Venus on the evening of Wednesday May 12, 2021. And astronomer Dean Regas was there to capture it. The video was taken with a camera phone attached to a small portable telescope.

Happy Birthday Mitchel Telescope!

The Cincinnati Observatory's main telescope turned 175 years old last April 14 and we'd like to look back at how Astronomer Dean Regas gave a virtual tour of the scope last year.  So wish us a happy 176th birthday today!

Mae Among the Stars

Dean reads the children's book about astronaut Mae Jemison and her dream to become an astronaut.  Thank you to the Cincinnati Museum Center for including this in their Story Tree Time program. 

Jupiter and Saturn Come Together

On the nights of December 20, 21, and 22 the largest planets in our solar system, Jupiter and Saturn, appeared closer together in the sky than they have since 1623.  In fact they were so close that you could see the two planets in a telescope at the same time!  

To the right is video captured by Astronomer Dean Regas through the Cincinnati Observatory's 175 year old telescope on December 21.

With the Cincinnati Museum Center

Dean shares a drink with CMC's Jessica Urban to tell the bizarre tale of the life and unbelievable death of the best naked eye astronomer who ever lived: Tycho Brahe.  It involves kidnapping, a nighttime duel, a fake nose, the construction and ruin of a castle-observatory, exile, deceit, and finally a strange-but-true demise.  It's a whodunnit in the year 1600.
