He was using a filter slider with an OIII filter in one slot. By sliding the filter in and out, it was possible to see which &#8220;star&#8221; was actually the nebula. He let me borrow the filter and slider so I could make a sketch at my scope. The star at the center of the sketch (also noted by hash marks) is the planetary nebula. Moving your mouse over the sketch will simulate the blinking effect. It looked like the nebula may have exhibited some dimension, but the seeing wasn&#8217;t the greatest, so I couldn&#8217;t be sure.<\/p>\n<p><b>Object Information<\/b><\/p>\n<p>NGC 5873 was discovered by Ralph Copeland in 1883.<\/p>\n<p>NGC 5873 is also catalogued as PK331+16.1, ESO 328-PN034<\/p>\n<table color=\"ffffff\" width=\"470\" border=\"0\" cellspacing=\"2\" cellpadding=\"4\" style=\"line-height: 150%\">\n<tbody>\n<tr>\n<td bgcolor=\"#3f4d6d\"><b>Subject<\/b><\/td>\n<td bgcolor=\"#3f4d6d\"><b style=\"color: white\">NGC 5873<\/b><\/td>\n<\/tr>\n<tr>\n<td bgcolor=\"#3f4d6d\"><b>Classification<\/b><\/td>\n<td bgcolor=\"#3f4d6d\">Planetary Nebula (2)<\/td>\n<\/tr>\n<tr>\n<td bgcolor=\"#3f4d6d\"><b>Position*<\/b><\/td>\n<td bgcolor=\"#3f4d6d\">Lupus [RA: 15:12:50.73 \/ Dec: -38:07:32.9]<\/td>\n<\/tr>\n<tr>\n<td bgcolor=\"#3f4d6d\"><b>Size*<\/b><\/td>\n<td bgcolor=\"#3f4d6d\">.22&#8242;
