Image Description and Details: IC 443_IC444_Sh2-249

Hello everyone. I propose my latest work. It is the Medusa Nebula (IC 443) present in the constellation of Gemini, accompanied by many other objects including IC 444 and Sh2-249. If you go to look at the high resolution photo in the direction pointed by the white arrow there is a small nebula...even with the astrometric resolution it has not been resolved. Does anyone know what it is?

IC 443 is a supernova remnant located in the constellation of Gemini. It is believed to have originated from a supernova that exploded in a period between 3000 and 30,000 years ago

IC 444 is a small reflection nebula of 32 square arc minutes in the constellation of Gemini.

Sh2-249 is an emission nebula visible in the constellation of Gemini. It is located in the western part of the constellation, in the direction of the bright star μ Geminorum, whose light disturbs its observation; it appears immersed in a rich star field.
