To say this was a dream come true for me, is in no way an exaggeration. I have wanted to photograph the night sky under these telescopes since I started doing astrophotography. I am so grateful to those that helped make this happen. I had 4 cameras going at once to get as much as I could in the 4 hours we had, so there’s much more to come. I am forever grateful to Jeff Hellerman Paul Vosteen Jill Malusky and Green Bank Observatory #astrophotography #outerspace #WestVirginia | Dave Green
