Well, I just posted this to the previous APOD, but here it is again, since it is directly comparable, even if mine comes up short. Mine is essentially the same view, astronomically, taken about six hours later. Notice the moon's motion wrt delta and epsilon Piscium, along its line of motion. It is displaced to the upper left in my later exposure. My exposure is inferior largely due to sloppiness ... motion blur and poor focus. ( Focus is very demanding with the high resolution focal planes we have today. )

Aside from that, the APOD seems to have better exposure balance, noticeable in the moon. According to Starry Night, I had 5% illumination instead of 4% illumination 6 hours earlier, but still, the illuminated portion of the disk is subdued in the APOD, compared to mine. I'm thinking he had a shorter exposure at higher effective "speed" ( I was at 2000 ) but I don't know if he had something fancy going on there.

Anyway, as I say, very instructive for me.
