Description

This image of the iconic emission nebula in Cassiopeia was taken over four nights, totalling 11 hours of integration from my Bortle 6 location. Despite weak sharpness and some problematic stars, this image represents a personal achievement as it was taken in poor conditions:
  • Shot near or at full Moon
  • Seeing was poorer than average
  • Focus was done manually on a Mak without a Bahtinov mask
  • Image scale is 0.33 arcsec/pixel

But despite all this, my own stubborn perseverance, careful focusing, accurate polar alignment, good guiding and choice of filter all came together to produce an image that, while never going to win any award, is a personal landmark.
