If you're a mobile user and it's finding it hard to explore the star map here, consider accessing the original website or downloading the app. I know there's links to it on the map itself down below, but I'm just trying to make it easier because i don't know how much it can look weird on a mobile device lol.
it's very simple but, a quick "tour" around the star map: Click on the tribar icon (≡) to hide the menu that shows up when you first load the page. The icons at the bottom of the screen turn grids, guides, and other features on and off. You can click on any object on the sky to see more detailed information on it. Also, in the "Observe" section on the upper right corner you can record your own observations and access the calendar to check events.
