    Explanation:
    What are some of the most interesting astronomical objects you can see in the night sky, armed with a good pair of binoculars or a small telescope? If you live in the Northern Hemisphere, you can look for the very popular objects in the Messier Catalog (most of them, but not all, are also visible from the Southern half of the Earth). The featured image shows all 110 objects in the catalog, shown at uniform scale. Charles Messier created the catalog in the 18th Century. He was interested in comets, and his catalog was a list of known comet-like "objects to avoid" in the sky when observing or hunting for comets. The deep sky objects in the catalog include a supernova remnant (the Crab Nebula, M1), other galaxies (such as Andromeda, M31), nebulae (e.g. the Orion Nebula, M42, a star forming region) and stellar clusters (such as the Pleiades, M45, a bright young open cluster).

  2. STAR PARTY CHAOS

    1 Night at a Star Party… BEST NIGHT EVER

    one night. that’s all it took

    rocked up to the Messier Star Party thinking it’d be a chill night looking at stars… yeah nah

    ended up interviewing Norm about a planispheric astrolabe he literally designed and built, Hugh with his home-built 6" RC, and Phil from the radio astronomy crew about what they’re doing with the dish out at LMDSS

    ran Messier Bingo, gave away prizes, pointed telescopes at the Sun, then spent the rest of the night imaging under stupidly good skies

    and somewhere in between all that… just hung out with a bunch of legends I haven’t seen in ages

    one night, way too much fun, zero regrets

  4. Stargazers, bittersweet news — our 2026 Messier Marathon at Westport Observatory is cancelled. Today's the first day of spring, and spring showed up RIGHT on cue with clouds and rain to shut us down! We were ready to chase all 110 Messier objects, but Mother Nature had other plans. Clear skies ahead! was-ct.org/
