I believe I finally found Neptune after a few weeks of trying to locate it. It was difficult because the object is so much fainter than Uranus. Also, it is much smaller than Uranus. When I first saw it I thought it was an out of focus star!
But what really was unexpected for me was how the disk brightness per unit area of the planets disk was lower than that of Uranus. I thought it would appear just like Uranus only smaller. Not so, it has a more blue-green-gray appearance versus blue-green for Uranus .
My guess is this because the planet lies some 10 AU farther away from the sun than Uranus? I would welcome some input from this forum for I want to know other observers opinions.
