Minkowski 1-64 (M 1-64, PK 064+15.1, PN G064.9+15.5) Planetary Nebula in Lyra. Taken over several
nights from July 19, 2019 through July 27, 2019. Imaged with Starlight Xpress’ SX-825 camera and a
Celestron EdgeHD 9.25 at f10, on a Losmandy G11/Gemini mount. The H alpha subframes were 12 and 15
minutes binned 1x1 and the OIII subframes 12 minutes binned 1x1, while the RGB subframes were
2 minutes binned 2x2, resulting in the following total exposures L:R:G:B = HA+OIII):(R+Ha):(G+OIII):
(B+OIII) (min) = (381+252):(40+381):(40+252):(40+252). Captured with Nebulosity, calibrated, sigma
combined in Iris with other processing using PixInsight LE and Photoshop CS. North is up.
