Around the time of the equinox, the ecliptic meets the horizon at a favorable angle and a unique phenomenon may become apparent: the zodiacal light. This diffuse band of light can be briefly seen after sunset or before sunrise from a moderately dark location.

Call it Extreme Astronomy, a sport of sorts. Popular Messier marathons are in this vein. I find that this kind of pursuit can sharpen my skills and hone my knowledge. While I never tire of showing folks Andromeda during public observing, it can be fun to aim at a lesser known object that no one else at the star party has in the eyepiece. Anyhow, below are my top 12… some I’ve seen, some I’ve attempted, and some I know of but have yet try. I’ve tried to keep things as “visual” as possible (i.e. telescope only!), but technology can present is own challenges as well. After all, I’d hate to think I’ve finally seen everything!
