Description

Here I have processed data from last year of these quite faint objects from the Sharpless catalogue using the latest processing tools including starless processing. They were once thought to both be supernova remants (planetary nebulae) but now only Sh2-224 (the one to the left) is recognized as a supernova remnant, with the typical blue Oiii mixed with Ha emission. Sh2-223 does not contain any detecatble (Oiii) and is now thought to be a Ha emitting nebula energized by the star BD+41 1144. For those that want to read more about thes objects a good start is, as allways, to read Gary Imm's description of his rendention of these objects (https://www.astrobin.com/380492/F/), where also BD+41 1144 is pointed out.

To me Sh2-224 looks like some kind of flying creature, or rather gliding, coming in for landing on Sh2-223. On Astrobin I have seen a few different suggestions for names for Sh2-224, including the Chef in Hat Nebula or Rice Hat Nebula.
