After looking more critically at the D460 image I took of Jupiter last night I noticed the red and blue “fringes” on the planet. I discovered this is a phenomenon known as Atmospheric Prismatic Dispersion. I don’t see it in any of the webcam images so it could possible be something about the optical coupling of the camera to the eypiece… or perhaps more likely is that the D460 is more sensitive to those wavelengths than the LPI.
Another indication of my poor conditions is the fact that Jupiter was about 59º above the horizon and I was still experiencing this effect… if it truly was APD.
