Doing a Messier Marathon means spending a lot of time on your knees. Here's Janetrying to dig out one of the early evening Messier objects about to set.

When the sky is clear, and we're not out on the sidewalk showing the firstquarter Moon or planets to our regular audiences, we pack the telescopesand get out of town. There are no dark skies anywhere near Los Angeles,and after months of in-town observing, we yearn for the Milky Way, darkclear skies, and a chance to observe objects in our galaxy and beyond.

We like to travel to a great location about 150 miles east of our Monroviahome. It's a nice spot in the eastern Colorado Desert just off Interstate10 between Indio and Blythe, CA.

Each year, some amateur astronomers participate in an annual homage tothe objects discovered by 18th century comet hunterCharles Messier. The MessierMarathon is a one-night attempt to find as many of the 110Messier objectsas possible. These objects,mostly star clusters, nebulae, and galaxies, are not evenly distributedin the celestial sphere. There are regions in the sky heavily crowded with M objects,especially the Virgo Cluster and the region around the centerof our own galaxy, the Milky Way. For those of us in mid-northern latitudes, all 110 Messier objects are observableduring one night in March when the Moon is near its new phase. This year March 25/26th was thebest weekend for the marathon.

March 25-26, 2006

We arrived at our destination an hour before dusk, and by 7:00 p.m. withtelescopes aimed nearly at the western horizon, we were trying to nailthe first Messier objects, faint galaxies which set early. We werebeseiged by clouds near the horizons. We soldiered on, missing onlyone of the first dozen objects, M77, a beautiful spiral galaxy, due toclouds. There were still 109 challenges ahead. By 8 p.m. we had seenthe dozen first sunset objects, and took a break.

At 10:30 p.m. we were done with all the evening objects and had a fewhours to wait for the Earth to rotate and for the summer milky wayobjects to begin to appear. We had observed 70 of the 110 objects, andtook a three-hour nap. After 2 a.m. there is a mad rush to get the finalthirty objects before dawn. The rising crescent Moon and bright Venusalso graced the morning skies. We missed five of the last objects due toclouds, but were happy with our final tally of 104 objects.

The weekend was fast approaching, and with it, a four-day old crescentMoon would brighten the sky. The weather looked to be much better inthe desert than at home, so we decided to try another marathon, thistime armed with a few extra charts for the most difficult objects. Inaddition, I thought it would be fun to observe the Messiers on theMoon — the craters named in honor of Charles Messier are amongmy favorite lunar targets. While waiting for the sky to darkenI used my favorite Moon referenceHitchhikers Guide to the Moon, which is based onAntonin Rukl'sAtlas of the Moon, and checked off 90 craters, lakes,seas, rilles, oceans, mountains, bays visible on the slim four-day oldcrescent Moon.

As soon as the first stars were visible, we lowered the big telescopesnearly to the western horizon in search of the challenging galaxies. Thistime, we found M77, but failed to get the other early evening galaxy,spiral galaxy M74 in Pisces, one of the 20 faintest of the total list. Ohwell. But we were successful with the next 109 objects.

In between the Messier Marathon, we also observed Mars, Jupiter,Saturn and Venus, and 8 moons of Saturn, the 4 Galilean moons of Jupiter,and two comets. Added to the 90 lunar features, this brought my totalto 109 additional observations.

Observing in the desert

The dry high altitude desert air is great for observing. We always bringplenty of water, and take frequent breaks. After every observation, weremembered to have a sip of water to keep from getting dehydrated. Wealso bring a trash bag which stays in the car, and bring all our garbageback with us, leaving nothing behind. We also bring plenty of layersof clothing. It was 70 degrees at sunset, and 38 degrees at dawn.

The Messier Marathon is not the best way to see these splendidobjects. For example, the great Andromeda Galaxy, M31, is best viewed inthe fall, when it is higher in the sky. Seeing it as it sets against thesunset haze in March shows a faint glow, if you are lucky. It reminds meof the view we have of our own sweethearts first thing in the morning.We know they are beautiful, but we also know they'll look a lot betterafter they've been up a while.
