M27 in Vulpecula This is my first image through a CMOS camera (other than the Canon 60Da). The image is of M27 in O[III] and Ha, which is a planetary nebula discovered by Messier in 1764. It was taken through an SBIG STC-7 CMOS camera through a Takahashi E-180 f/2.8 astrograph mounted on a Paramount ME on the nights of 5, 7 November 2021 (42 x 120 sec OIII lights, 36 x 120 sec Ha lights, grain 5.5 electrons/ADU, corresponding darks, flat darks, flats all at -5 degrees C). Processed in PixInsight 1.8.8-9 Ripley (x64).
