Your experience of finding some objects harder to see than other times actually shows how your experience is actually growing to notice this change in seeing, and identify it from one session to the next,

Seeing is very variable. What seems like a good night might actually be quite poor. If you struggle to see the fainter stars that you would otherwise see, or the stars twinkle a lot, there is a tell tale sign. If you spot some of the faint fuzzy patches of the larger clusters, or the twinkle is less noticeable, then things are looking better.
