Jones-Emberson 1 (JnEr 1, PN G164.8+31.1, PK 164+31.1) Planetary Nebula in Lynx. Taken over several
nights from Feb. 06, 2022 thru March 23, 2022. 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
15 mintues 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) = (495 + 390):(54+495):
(54+390):(54+390). Captured with Nebulosity, calibrated, sigma combined in Siril with other
processing using PixInsight LE, Photoshop CS and GIMP. North is up.
