Patchick 10 (Pa 10, PN G035.2+05.2) Planetary Nebula in Serpens Caput. The nebula was discovered by
Dana Patchick of the Deep Sky Hunters collaboration project. Taken over several nights in July and
August 2018. 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 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) = (440+400):(68+440):(68+400):(68+400). This image is
displayed at 0.57 arc-seconds per pixel. Captured with Nebulosity, calibrated, sigma combined in Iris
with other processing using PixInsight LE and Photoshop CS. North is up.
