Sharpless 224, a supernova remnant
A rather faint nebula in Auriga, Sharpless 224 is the remnant of a supernova explosion. This image is an integration of 19 hours of data captured with an Optolong L-Ultimate dual narrowband filter and it really needs at least double that. I also took 7 hours with a luminance filter for the stars. The camera was the QHY268C and my telescope was the William Optics Zenithstar 103. All post-processing was carried out in PixInsight.
