NGC 1977, The Running Man Nebula in Orion670 viewsA reflection nebula embedded in a bright HII region, Sh2-171, found in Orion's Sword near the Great Orion Nebula M42. Sh2-171 also includes two other nebulae and the star cluster NGC-1981.
M108-20230512-OSC1.jpg
M108 and M97 in one frame670 viewsBarred spiral galaxy M108, nicknamed the Surfboard Galaxy, about 28 million light years away; and planetary nebula M97, the Owl Nebula, 2030 light-years away, both in Ursa Major.

Messier 67 - Open cluster in Cancer670 viewsSometimes called King Cobra or Golden Eye Cluster. Distance 2600-2900 light-years. Estimated age 3.2 to 5 billion years.

M74, Spiral Galaxy in Pisces670 viewsGrand design spiral galaxy with two clearly defined spiral arms winding counterclockwise from center. About 32 million light-years distant.
M23-20230523-V1.jpg
M23 - Open Cluster in Sagittarius669 viewsIn front of an extensive gas and dust network. Around 300 million years old and 2050 light-years away.
NGC2237-20210205-LRGB-i3.jpg
NGC2237 - The Rosette Nebula664 viewsEmission Nebula / HII region in Monoceros, with open cluster NGC 2244 in center of nebula.

NGC 4244, the Silver Needle Galaxy in Canes Venatici661 viewsAnother "needle" edge-on galaxy, member of a group of galaxies associated with Messier 94 in the Virgo supercluster; about 14 million light-years from Earth.
NGC3521_LHARGB1.jpg
NGC 3521, "flocculent" spiral galaxy in Leo660 viewsNGC 3521 is termed a "flocculent" spiral galaxy because it has patches or clumps of stars breaking up the continuity of the spiral arms. Self-propagating star formation is thought to account for the patchiness. The galaxy lies about 26 million light-years away from us.
NGC2359_20220123_LRGB1D.jpg
NGC 2359 - Thor's Helmet659 viewsAn emission nebula in the constellation Canis Major; about 12,000 light-years away. Consists largely of interstellar gas swept up by the central star, and partly of material from the star itself, which is an extremely hot, massive Wolf-Rayet star in a short-lived pre-supernova stage.
NGC7023_20240706_RASA11_NBZ2.JPG
NGC 7023, the Iris Nebula658 viewsReflection nebula in Cepheus. Actually the nebula is LBN 487, and NGC 7023 is a star cluster within the nebula. 1300 light-years away and 6 across.
