Description

This interesting and well documented supernova remnant, located about 6500 light years from Earth, is always interesting to image. I like the story that the supernova was observed already in 1054 by the Chinese.  It looks very different in different wavelengths.  Visually,  by looking through a telescope, it looks mostly grey and fuzzy, and also so in many RGB images. In narrowband much more details are seen. My favorite is the Chandra X-ray image, showing some really interesting structure around the pulsar inside the nebula.

The nebula is a bit small for my telescope,  but still I tried to image it in late January 2022. Most images are from January 17, but some are from January 20, 28 and 30. I struggled with poor weather so I only got a small  collection of 5 minute exposures in SII (10), H-alpha (16) and OIII (16). I think I got some nice details.
