Interesting tool, would probably be super useful if I had more knowledge of the things floating around out there. I'm usually just concerned with photographing the galactic core on dark nights. I didn't have enough domain knowledge to figure that out with this tool though. I use PhotoPils on my iOS devices for astrophotography planning and that works great for my limited level of knowledge.
Don’t let lack of familiarity keep you from exploring. More and more tools/apps are available like TFA that lets you find things without knowing about them before hand. There’s no better way to learn than diving into the new to you object you just images all night. Don’t let some one tell you that you have to know an object intimately before imaging. How you progress through your journey in astronomy is up to you. Keep looking up!
