There is a funny story behind this capture. In SGP's Framing & Mosaic Wizard I entered in "Jones-Emberson 1". It brought me to this, which is obviously not Jones-Emberson 1, but Jones 1; even more faint and rare than Jones-Emberson 1. As with most faint planetary nebula, I usually just let it go capturing huge amounts of data automatically while working on my normal job that pays the bills, producing commercials. I let it go so long that I did not even go back to compare the data to Jones-Emberson 1. I find this hilarious and have to laugh at myself, yet at the same time this seems to be one of the best Jones 1 out there after I massaging the data. One of the best biggest mistakes I have ever made. lol

PK 104-29.1, Jones1, a Planetary Nebula in constellation Pegasus. OIII emission dominates the scene, hence the bluish color. There is some faint H-alpha emission in a nebula and very dim "blob" of Hydrogen alpha emission just under the nebula. There was no trace of SII emission. A very hot Central star can be seen as blue at the center of the Nebula.
