Description

This is the high resolution rendition of the NGC6543 PN image elsewhere presented (https://www.astrobin.com/xtfuos/?nc=collection&nce=2703). In this case, taking advantage of the rather good seeing in these two occasions (1.6" and 2") I have employed the drizzle technique to retrieve lost resolution due to undersampling. While probably not up to the raw resolution level of my first image many years ago it brings this image more in line with mainstream imaging canons showing more of the outer core as well as the envelope and, I can assure you, it wasn't easy sailing...
