The Wonders of the Universe
This is a video of my astrophotography shots, titled as “The Wonders of the Universe”. It features the planets Venus, Mars, Jupiter and Saturn, the Sun, the Moon, as well as deep-sky images of the Orion Nebula and Sirius. I have only started out a few months ago, so please be fair in your comments. The images in this video are taken with a Celestron Powerseeker 127EQ, and a Samsung S760 compact camera. The Solar images also have an Astrosolar Mylar Filter.
