Kronberger 33
(Kn 33)
PN G147.2+8.3

Kronberger 33 (Kn 33, PN G147.2+8.3) planetary nebula in Camelopardalis. The nebula was discovered by
Mattias Kronberger of the Deep Sky Hunters collaboration project. Taken Dec. 17, 18, 21 and Dec. 28,
2016. Imaged with CCD Labís Q285M camera and a Celestron EdgeHD 9.25 at f10, on a Losmandy G11/Gemini
mount. The H alpha and OIII subframes were 20 minutes binned 1x1, while the RGB subframes were 4
minutes binned 2x2, resulting in the following total exposures L:R:G:B = (Ha+OIII):(R+Ha):(G+OIII):
(B+OIII) (min) = (260+300):(64+260):(64+300):(64+300). This image is displayed at 0.57 arcsec/pixel.
Captured with Nebulosity, calibrated, sigma combined in Iris with other processing using PixInsight LE
and Photoshop CS. North is up.
