Date/Time of photo:
1975 C-8 prime focus, CGEM mount, Orion Star Shoot Pro, Orion Sky Glow Filter, Orion Auto Guider with 80mm. 5 - 5 minute images stacked using MaximDL and Black Point set in Photo Shop.
Grocery Shopping center less than 1/4 mile away from house and the lights of Tijuana product a sky glow up to 45 degrees in the southern sky. Have a one hour window to image M20 between my house and the neighbors pointing due south. I'm surprised that a Sky Glow filter would allow an image as good as this; just wonder what it would be like taken at a Dark Sky Location.
