Fakta om bilden:<\/p>\n\n\n\n

* Nebulosan ligger cirka 1400 ljus\u00e5r bort. Bilden p\u00e5 nebulositeten \u00e4r tagen med smalbandsfilter H\u03b1 och OIII. Stj\u00e4rnorna \u00e4r tagna med R,G,B filter. De tv\u00e5 bilderna \u00e4r sedan sammanslagna till en bild.
* Som vanligt fotograferat fr\u00e5n Malm\u00f6 och dessutom denna g\u00e5ng under n\u00e4stan fullm\u00e5ne.  
* Bildf\u00e4ltet \u00e4r cirka 40\u00b4 x 30\u00b4 och uppl\u00f6sningen 1,31\u201d\/pixel.
* Bilddata.  Kamera: mono cmos med filterhjul.
 * Optik: Refraktor 130 mm  f\/4,5.
   * Exponering: H\u03b1, OIII  15 x 5 min vardera,  R,G,B  20 x 20 sek vardera.  Summa 170 min.<\/p>\n\n\n\n
