Opaque Orb in the Night Sky in Murrieta

I was outside at night looking at the stars through my binoculars right above Sagittarius. Suddenly, as I was panning the sky I saw an opaque blurry orb moving downward in a straight line. As soon as I saw it, I followed it until immediately, it disappeared. I knew it couldn't have been a helicopter or an airplane because I still would've been able to see the blinking lights. It also couldn't have been a meteor because a meteor is just a fast streak in the sky which is completely different from what I saw. This orb was large compared to the stars in the night sky, it was thick and blurry as if it were an unfocused star in a telescope.
