It's helpful not to lose sight of the forest because of the trees, IMO. I think it's real easy to get so caught up in the technical aspects of the ship, Starfleet, etc., that the story and characters are drowning in them. Details are important, but too much detail can be as bad (if not worse) as not enough detail because it can bog down a story. Not everything requires a full page or even a full paragraph explanation.
When I was writing fanfics (in ancient times), I tried to visualize them as 40-minute stories (an hour long episode without commercial breaks) and would read the dialogue of my characters aloud to see if the story was becoming too talky with exposition or if I was spending too much time describing things in the narrative and wasn't really moving the story or the characters along well.
