PN G194.2+02.5

Jonckheere 900 (J900, PN VV28, PN G194.2+02.5, PK 194+02.1) Planetary Nebula in Gemini. Taken
Jan. 25 and Jan. 26, 2022. Imaged with CCD Labís Q285M camera and a Celestron EdgeHD 9.25 at f10,
on a Losmandy G11/Gemini mount. The OIII and H alpha subframes were 3 minutes binned 1x1, while the
RGB subframes were 3 minutes binned 2x2 resulting in the following total exposures (OIII+HA):(R+Ha):
(G+OIII):(B+OIII) (min) = (72+84):(39+72):(39+84):(39+84). This image is upsampled 2x and cropped
from the original, and is displayed at 0.28 arcsec/pixel. Captured with Nebulosity, calibrated,
sigma combined in Siril with other processing using PixInsight LE, Photoshop CS and GIMP. North is up.
