The small planetary J320 seen in this image was discovered by Jonckheere 1916. Current estimates of distance as of 2008 put it at around 6120 parsecs, with the brightest central disk about 10 arc seconds along its longest axis. For comparison, M57 is 787 parsecs away or about 8 times closer, making them not dissimilar in size.

Recent studies estimate the age based on the spectrogaphically measured velocities of the nebula's components and its distanced at somewhat over 1825 years, with the the three bright lobes (two seen here roughly perpendicular and one toward us) being produced by the central star during several events during the life of the nebula. In addition, the knots that can seen outside the bright disk were ejected from the central star along yet different axes during several episodes, the most recent of which occurred about 820 years ago.

Seeing was good for a couple of nights this week, giving me a chance to image some small bright planetaries during the full moon. Seeing was approaching as good as it gets from my backyard, which is closed to sea level. This planetary nebula is quite small and bright, so I live-stacked 0.5 second exposures with careful focusing and as tight a FWHM filter setting as possible for sky conditions. Each of the 5 subs stacked to produce this image were captured by live stacking 360 half second frames to produced 3 minute images, with 2 of the 5 images using an IDAS filter (when the full moon was up) and the remaining 3 a couple of night later using a IR/UV Cut filter before the moon rose. I then stacked/processed the 5 images using Fitswork 4 to produce the final image here. The two faint adjacent galaxies don't show up well because of the short exposures geared toward capturing the much brighter nebula. Two or 3 second subs when live stacking would have showed these galaxies much better.
