M108-20230512-OSC1.jpg
M108 and M97 in one frame2 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.Nov 17, 2023
IC2118-20231111-NBZ_v1.JPG
IC2118, the Witch Hunt Nebula2 viewsFaint reflection nebula in Eridanus, usually known as the Witch Head Nebula, but it doesn't look much like a witch's head in this view, shot with an IDAS NBZ nebula enhancement filter, so maybe this version is best titled the "Witch Hunt Nebula." About 900 light-years away; illuminated by the nearby supergiant blue-white star Rigel in Orion.Nov 17, 2023
IC1848_20231021_RRBG_v2.JPG
Westerhout 5, The Soul Nebula1 viewsEmission nebula in Cassiopeia, 7500 light-years away. Also known as Sharpless 2-199, LBN 667 and IC 1848, although the last is properly the designation of a star cluster within the nebula. Eastern neighbor of the Heart Nebula.Nov 17, 2023
IC1805_20231020_NBZ_v1.JPG
The Heart Nebula1 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.Nov 17, 2023
M23-20230523-V1.jpg
M23 - Open Cluster in Sagittarius1 viewsIn front of an extensive gas and dust network. Around 300 million years old and 2050 light-years away.Nov 17, 2023
M33-20231111-OLQ.JPG
M33, the Triangulum Galaxy1 views2.73 million light-years away; third largest member of the Local Group of galaxies.Nov 17, 2023

M77 and Friends2 viewsBarred spiral galaxy in Cetus (left side of picture), about 47 million light-years from Earth. A Type 2 Seyfert galaxy with an active nucleus. The spiral galaxy at right is NGC 1055. The spiral galaxy NGC1072 is also seen as a tiny oval near the bottom center of the frame.Nov 17, 2023

NGC 5907 - The Splinter Galaxy1 viewsAlso known as the Knife Edge Galaxy. About 50 million light-years from Earth. Located in the constellation Draco.Nov 17, 2023
M90-20230513-LRGB1.jpg
Messier 90, Spiral Galaxy in Virgo1 views59 million light-years away. Contains little gas and dust and hence does not have much star formation; believed to be evolving into a lenticular galaxy.Nov 17, 2023
M59-20230511.jpg
Messier 59, Messier 60 and friends1 viewsM59 is the eilliptical galaxy in the center of the frame; above it is the elliptical galaxy M60 with nearby spiral galaxy NGC 4647. Numerous other galaxies are also in the picture, including spirals NGC4606 and NGC4607 in the bottom left quadrant.Nov 17, 2023
