Uranus September 8, 2020
45cm Newtonian reflection. The brightness of Uranus is about magnitude 6. In the 45cm aperture, Uranus appears to be a beautiful light blue disk even at 400x magnification. It’s a pity that the internal pattern is not visible. The reason the color and IR images aren’t beautiful disc images is because the optical axes are not perfectly aligned!
