June 5 A Novel Approach to Star Trails by:

A novel approach to star trails Featured in National Geographic and Nature, Canadian amateur astronomer Christian Sasse explains how he creates his unique star trails, by superimposing images. Saturn's moon may have tipped over Scientists used Cassini spacecraft images to show that Saturn's moon Enceladus may have tipped away from its original spin axis by 55 degrees - more than halfway toward rolling onto its side. Circumpolar stars don't rise or set Many star trail photos rely on circumpolar stars, which don't rise or set, but instead stay above the horizon all hours of the day, every day and every night of the year. Astro festivals, star parties, workshops Summer fun!  Find a star party near you.
