This is a somewhat intriguing planetary nebula. Some of the professional images of it are taken in OIII, Ha and Nitrogen. This gives an almost Hubble palette of the object. So I thought I would try doing likewise. Alas that was not capable out of my meager instrument. The SII in this object is very faint and took quite a few hours just to get a reasonably bright image. In then end it did not add anything to the image.
The object is found in Ophiuchus at around 2500 light years. It is reasonably faint at 12.9 magnitude and would most likely have only shown a ring when observed by William Herschel. The fainter halo would not have been visible at all; perhaps only a faint nodule or two seen. An interesting challenge for anyone to try.
The image contains Luminance, Ha, OIII, and RGB. Totally 22.6 hours of integration.
