Enjoyed This One...
Love the gorgeous subtle green and blue colours in the nebulosity. Seen heaps of images of this wonderful planetary, but never the different contrasts across the planetary disk.
I think you will find the magnitude of the nebulosity is not 14th but is more like either 11.6v and 11.5B magnitude.
Considering the brightness of this object, it remains extraordinary that it was discovered so late by Lewis Swift in 1857. You should note that the central 9th magnitude blue star is not the central star of the nucleus, but is the one below it - being 11.35v or 10.96B magnitude.
The red star is RZ For - a semi-regular variable star, and is near maximum brightness at 8.4v magnitude. The blue star also makes a nice contrast - often not placed in the image field in preference to the planetary.
I really like this pic Eric.
