If you are in Southern California sometime from June 21 - August 3 you should visit the "Capturing the Cosmos: a Personal Journey" exhibition of astrophotos. The images were all taken by my friend Dennis Mammana. If you aren't familiar with his work check out his website and the gallery of his images at The World at Night website.
I am sure you will agree that he has taken some amazing images. The showing will be in the OPT Underground gallery in Oceanside, CA. All of the images in the show will be available for purchase and a portion of the proceeds will go toward the Wounded Warrior Project.
