Minkowski 1-79 (M 1-79, PK 093-2.1, PN G093.3-02.4) Planetary Nebula in Cygnus. Taken over several
nights in Sept. and Oct. 2015. Imaged with CCD Lab’s Q285M camera and a Celestron EdgeHD 9.25 at f10,
on a Losmandy G11/Gemini mount. The OIII and H alpha subframes were 15 minutes binned 1x1, while the
RGB subframes were 4 minutes binned 2x2, resulting in the following total exposures (HA+OIII):(R+Ha):
(G+OIII):(B+OIII) (min) = (405+330):(64+405):(64+330):(64+330). 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.
