[QUOTE="blackstar, post: 721715, member: 47518"] Oh, thank you so much, Cindy -- for all the detailed explanations and helpful information. I have studied about hyperfocal distance earlier and got the photopills app finding the HD for my camera & lens as 4.66m (all in my previous post). And I already experimented with that to somewhat satisfying, not ideal though, outcome: since D3500's mechanics in auto-focus is very sensitive to moving and vibrating, once auto-focusing to hyperfocal distance is done and mode changed to "M", the focus ring would at least swing a little out of focus. But it is still close at HD and I can do some micro-focusing to make sure everything (stars) in focus. I think I have mostly (not completely and perfectly) done my work on focusing infinity for preparing night star shoot. The other night's moon shooting practice came with some focusing issue that, I think, was due to natural foggy conditions. I picked one bad night after all. Now I am also dipping into learning post-processing. So many things to study, learn, and experimenting on photography! I am taking all in hard fashion, but enjoying them at the same time.
