As currently-written, the moon and the availability of its light plays a major role in the last part of my WIP. At least, it was supposed to. I looked up moon phases and moon rise and set times for all the times I mention it, and I thought I had everything right. But a beta reader, who had to look into the same matter for her WIP, has pointed out that I got one appearance of old Luna screamingly, unscientifically wrong. I had a waning gibbous moon rising two hours before sunset, when they never, ever appear that early. In fact, on the date I want, the moon rose two hours after the sun went down. Don't know how I misread the lunar chart that badly--- that's what the screaming is about--- and the webpage I got my information from has disappeared. Yeah, I bookmarked the site, but the town I was using as my reference point no longer comes up in the search bar (Note to self: Make pdf copies of all crucial online research). I was thinking about saying "What the heck, this is fiction, I'll have the moon do what I want." But I'm not writing fantasy or other-worldly SciFi, and I don't want my readers poking holes. So, okay. I'll rewrite those sections using the stars instead. My protags will be out in a remote area with little or no light pollution on a clear night, so until the moon actually rises the stars will be out in all their glory. What I need to know is, can anyone recommend a good app or website where I can enter particular dates, times, and coordinates, and come up with the constellations, planets, etc., that would be visible then, and learn where in the sky they would appear, and how far above the horizon they would be? Thanks.
