Here is my last NGC7635 done with new Baader narrowband filters. At the bottom of the image below the Bubble you can observe a smal planetary nebulae called KjPn 8 or PLN 112-0.1.
KjPn 8 (PLN 112-0.1) is an unusually-shaped (14′ x 4′) planetary (PN) nebula located in the Constellation of Cassiopeia at RA 23h 24m 10s and DEC +60d 57m 30s. It is partially embedded in hydrogen nebulosity from the Bubble Nebula complex and the open cluster, M52. The signal is mainly in Ha and a small amount in OIII (I have very small signal with SII 7nm).


Voici ma dernière NGC7635 réalisé avec les nouveaux filtres à bande étroite de Baader. Au bas de l'image, sous la bulle, vous pouvez observer une petite nébuleuse planétaire appelée KjPn 8 ou PLN 112-0.1.
KjPn 8 (PLN 112-0.1) est une nébuleuse planétaire (PN) de forme inhabituelle située dans la constellation de Cassiopée à RA 23h 24m 10s et DEC + 60d à 57m 30s. Elle est partiellement noyée dans la nébulosité d'hydrogène du complexe de la nébuleuse de la Bulle et de l'amas ouvert M52. Le signal est principalement en Ha et un peu en OIII (j'ai un très petit signal avec SII 7 nm).
