Kohoutek 2-5 (PN K2-5, PN G014.9+06.4, PK 014+06.1), planetary nebula in Serpens Cauda. Taken over
several nights from July 10, 2023 to July 21, 2023. Imaged with Starlight Xpress’ SX-825 camera and
a Celestron EdgeHD 9.25 at f10, on a Losmandy G11/Gemini mount. The H-alpha and OIII subframes were
12 minutes binned 1x1, while the RGB subframes were 3 minutes binned 2x2, resulting in the following
total exposures L:R:G:B = (HA+OIII): (R+Ha):(G+OIII):(B+OIII) (min) = (396+360):(48+396):(48+360):
(48+360). Captured with Nebulosity, calibrated, sigma combined in Siril with other processing using
PixInsight LE, Photoshop CS and GIMP. North is up.
