Sharpless 221 and 216
Two neighbouring nebulae in the northern constellation of Auriga illustrate different outcomes for an ageing star. The nebula on the right, #221 in the Sharpless catalog, is a supernova remnant, created when a star exploded catastrophically. The nebula on the left, Sharpless 216, is a planetary nebula created when an ageing star expelled its outer layers.
This image is an integration of a total of 22 hours of data captured with a William Optics Redcat51 telescope and ASI2600MCPro camera. An Optolong L-eXtreme filter was used and all post-processing was carried out in PixInsight.
