StarTeller

This is a very handy app. Quick and easy to use. Helps prioritize what to focus on and what’s coming up. Huge database of DSO objects.

Great for beginners

I’m pretty new at Astro-photography but this app has been great so far. Not only does it let me know the best things to see each night but it shows where it exactly is and the path it traces through the sky. Definitely would recommend for anyone new

Seriously Great App! Pro and casual stargazers!

I went star gazing the other night and tried this app primarily because it doesn’t have a crazy tier structure that requires higher payments for the features I actually want for the few times a year I go out on a serious trip - like the red light background that doesn’t mess with my night vision while using my phone. Long story short, it’s pretty awesome. I may even go out more after seeing some of the pics of what’s out there and the fact that the app actually helps me find them.

Great app

This is a really great app. Very easy to use. Quick. Lots of useful information regarding the best time to view thousands of galaxies, nebulae, etc. Highly recommended.
