I'm not much of an observer but I was start testing my C11 tonight after some major surgery and then I got carried away and spent 2 hours with my daughter looking around the moon, saturn and other stuff. The moon details were ultra sharp. Saturn was very clear too. I noticed that when jumping from the moon to saturn I had to refocus and vice versa. The collimation was spot on and it wasn't mirror flop either but because saturn is side on right now it was very obvious I could see two lines for the ring until re-focusing. The focus point was extremely tight and very obvious but clearly different for the two. Is this normal? I thought whether you looked at a star or a planet or the moon you still focused to the same point (infinity)?
