Patchick 4 (Pa 4 PN G089.3+12.8) planetary nebula in Cygnus. This PN was identified by Dana Patchick
of the Deep Sky Hunters research group. Taken over many nights from Aug. 02 thru Sept. 25, 2016.
Imaged with CCD Labís Q285M camera and a Celestron EdgeHD 9.25 at f10, on a Losmandy G11/Gemini mount.
The H alpha subframes were 20 and 30 minutes minutes binned 2x2, while the Oiii subframes were 30
minutes binned 2x2. The RGB subframes were 4 minutes binned 2x2, resulting in the following total
exposures (HA+OIII):(R+Ha): (G+OIII):(B+OIII) (min) = (840+480):(60+840):(60+480):(60+480). This image
is up sampled from the original and 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.
