Genesis Observatory - Observatory / Equipment Info

		Observatory & Equipment

The Genesis Home Observatory - First Light June 2020 (41° 39’ 40” N / 83° 36’ 11” W) Bortel Class 8

Thanks to everyone who helped with this project especially my wife! I named it ‘Genesis’ because it is
my first observatory and also because of my faith in God. “In the beginning God created the heavens and the earth.” (Genesis 1:1)
