You don't have to have a telescope, but you should at least take a set of binoculars and install the SkySafari app on your cell phone or tablet. Make certain to be familiar with the SkySafari on your mobile device because urban and suburban astronomers often become disoriented because dense star fields make dark skies look so different. I also keep a copy of Sky & Telescope's Sky Atlas with me as a hard copy... Source: about 1 year ago

Binoculars like these. And an app like this or this. Head out to dark skies if you can. Pro Tip: a bean bag makes a great binocular observing chair. Source: over 1 year ago

As for apps, feel free to try out my app Nightshift if you're on Android. Other often recommended apps are SkySafari and Stellarium. Each app offers different features, so in the end it's a matter of personal preference or needs. Source: about 2 years ago

Stellarium as suggested gives you the opportunity to see which planets are above the horizon at any given time. If you want to to see what planets are visible in any given night without the need to scroll through the entire night, most astronomy apps like SkySafari have a 'Best of Tonight' feature that also lists the planets.

This is the Encoder Kit, like this one here. You need to connect your encoders to another device, like Nexus II (which what I have) or Nexus DSC Pro. Nexus II has its own WiFi network, which you can connect to with your phone/tablet. Then you can use app like SkySafari on your phone/tablet to connect to your telescope/Nexus II, by doing this your telescope will be a "Push-To" not "Go-To". Source: over 2 years ago

I also found HereJS and their pricing seems good, but again I have no idea. Source: almost 3 years ago

Here has a freemium tier (no credit card required) which gives you 250k transactions per month for free. https://developer.here.com/pricing Disclaimer: I work for here. - Source: Hacker News / about 3 years ago

Here has a generous free tier. You can get routes between locations, but you can't do isochrones anymore (they killed it due to lack of interest). Source: about 3 years ago
