Totaity minus 26 minutes750 viewsC2 - 25 min, 57 sec

M11 - The Wild Duck Cluster749 viewsOne of the richest, most compact and most massive open clusters known; estimates range from 3,700 to 11,000 solar masses. Radius 95 light-years. 6,120 light-years away, in the constellation Scutum. Supposedly the cluster resembles a flying flock of ducks, although as far as I can tell it could just as well be geese, crows or magpies.

NGC 7293 - The Helix Nebula in Aquarius749 viewsOne of the closest planetary nebulae, at only 650 light-years from Earth. Around 10,600 years old and 2.5 light-years in diameter. Sometimes known as the "Eye of God" or the "Eye of Sauron."
IC4604-20230513-LRGB2.jpg
IC4604, The Rho Ophiuchi Nebula749 viewsPart of the Rho Ophiuchi complex, a gaggle of interstellar clouds centered 1 degree south of the star Rho Ophiuchi. Estimated distance from Earth is 460 light-years.

NGC 253 - The Silver Dollar Galaxy746 viewsSpiral galaxy in the constellation Sculptor.

NGC1499-20151107.jpg
NGC 1499 - The California Nebula745 viewsAn emission nebula in the constellation Perseus, so called because it resembles the State of California in shape (though not in this image). About 1000 light-years from Earth.

First Contact plus ~30 minutes745 viewsAbout halfway through pre-totality.
IC1805_20231020_NBZ_v1.JPG
The Heart Nebula745 viewsEmission nebula in Cassiopeia, 7500 light-years away from Earth. The Fish-head Nebula is also seen as a cancerous outgrowth from the Heart Nebula at lower left.
Medusa_20220127_HaLRGB2A.jpg
Medusa Nebula (Sharpless 2-274)744 viewsPlanetary Nebula in Gemini. Discovered in 1955, first thought to be a supernova remnant, but Soviet astronomers in 1971 determined it to be a planetary nebula.
