Very likely my last image of 2023, this is the Jellyfish Nebula (IC443), the remnant of a supernova in the constellation Gemini. The two large orange stars are Mu and Eta Geminorum, two red giants at the feet of the rightmost of the two "stick figures" that form the constellation Gemini.

Astrophotograph of the Jellyfish Nebula. The "head" of the jellyfish is a oval ball of bright glowing ionized hydrogen and oxygen gases in dark orange with light blue color on the periphery. Fainter gases extend to the left in a triangular shape, formint the "tentacles" of the jellyfish.

This object at RA 06h 21' 40", Dec 23° 35' 00" approx. looks like a planetary nebula, however I could not find any PN in the Perek-Kohoutek Catalogue of Planetary Nebulae near these coordinates.

Closeup of the image from the original post showing a light blue blob of irregular shape with orange contour and details.
Annotated version of the image from the original post with a grid of celestial coordinates and a green circle showing the location of the the object shown in the closeup image.
