Discovery

It was discovered by amateur astronomer Dave Jurasevich using an Astro-Physics 160 mm refractor telescope with which he imaged the nebula on June 19, 2007 and on July 6, 2008.^[6] The nebula was later independently noted and reported to the International Astronomical Union by Keith B. Quattrocchi and Mel Helm who imaged PN G75.5+1.7 on July 17, 2008.^[7] The nebula measures 260″ in angular diameter with a central star that has a J band magnitude of 19.45.^[2]

Due to the faintness of the nebula and the fact that it is embedded in a diffuse nebula, it was difficult to discover.^[8]
