Last night I was looking at the planets using my Celestron 8SE.
I saw Saturn just fine, but I wasn't able to spot Titan except by using my averted vision. Titan's magnitude (according to Stellarium) is 8.83.
Then I used the Go-To feature to slew the telescope to Neptune. I saw something which looked bluish towards the center of the field. Or maybe I was just hoping it was bluish. So I drew a diagram of Neptune and the stars nearby on a piece of paper, and compared my drawing with Stellarium. Success! I saw Neptune for the first time!
But here is my question: all the stars around Neptune in the FOV had magnitudes around 8 or 9. I was able to see them plainly, without using my averted vision. Why can I seem them plainly but not Titan, which has about the same magnitude? Is it a reflectance issue?
