Description

According to my records M57 is, by far, my most imaged deep sky object of all times. Not a year passed by without me having a go at it, sometime for no purpose at all. No surprise to find it here then. Attempted high resolution but I know that much better exists nowadays and even in my times it was good but not outrageously so. Be as it may, it is right and proper to find it here, in this graveyard of old glories...

The bulk of the luminance data (at full focal length of over 2 meters) was captured in 2005 and provisionally I used old (2004 vintage) RGB data. Following that I picked up the data again adding better matching RGB and H-alpha (blended in the R channel) data taken in 2008 (but at a shorter focal length) to create this final image (drizzled 1.5x).
