Description

This image of M51 was taken some years ago under exceptional seeing conditions ... no El Nino.  Since that time we have all the AI programs so it was time to reprocess the data with these new tools.
Planewave CDK 17 + SBIG 16803 CCD + AstroDon filters.
LRGB + some H-a.
Taken from my home in Foresthill, CA.
