M97 (PN G148.4+57.0, PK 148+57.1, NGC 3587) Planetary Nebula in Ursa Major. Taken over several nights
from April 17 to April 28, 2013. Imaged with CCD Labís 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) = (330+360):(60+330):(60+360):(60+360). Captured with Nebulosity,
calibrated, sigma combined in Iris with other processing using PixInsight LE and Photoshop CS.
