a heart shaped object in the middle of space

This one is a composite of 2.5 hours of H-alpha from my QHY9 CCD and 2 hours of RGB from my modified Canon XSi DSLR. Both through my William Optics 66mm triplet at f5.6. They didn't line up perfectly, but if you don't look to closely it's a reasonably nice blend of nebulosity from the h-alpha data and star colours from the RGB data. Framed it just for kicks.

IC 1805, an emission nebula approximately 7,500 light years from Earth in the constellation Cassiopeia, is named the Heart Nebula due to its heart shaped appearance. The open star cluster Melotte 15 lies in the middle of the heart. The nebula is part of a large star forming complex in the Perseus arm of the Milky Way galaxy. The bright knot at the lower right (which some might liken to a male body part) is separately classified as NGC 896, and was the first part of IC 1805 to be discovered…

The California Nebula in Perseus 🔭 Looking for an astrophotography project for this fall? The California Nebula is an exciting one. This emission nebula is 60 light-years across! How to Photograph this Nebula: https://astrobackyard.com/california-nebula/ My latest attempt includes about 8 hours of total exposure from the backyard. (ZWO ASI2600MM Pro and RGB + Ha filters).

The Skull nebula The nebula is an emission nebula, a large star forming region located in the constellation Monoceros, the Unicorn. The nebula is a large cloud of gas and dust that lies near a large molecular cloud and is closely associated with the open cluster NGC 2244, whose stars were formed from the nebula’s matter in the last five million years. The Skull (or Rosette) Nebula’s appearance in optical light resembles a rose flower or the rosette, the stylized flower design used in…

Universe & Space 🪐 on Instagram: "@spacemajorr Undoubtedly this is one of the coolest spots in the night sky. 𝗡𝗚𝗖 𝟲𝟭𝟴𝟴 is an emission nebula located about 4,000 light years away in the constellation Ara. The bright open cluster NGC 6193, visible to the naked eye, is responsible for a region of reflection nebulosity within NGC 6188. ————————————————— Follow @spacemajorr ⠀ Credits: 🔭| @astrofalls & @starpunker #space #astronomy #astrophotography #universetoday #universe #nebula…
