I finally had a chance to get a Celestron Starsense attached to my Dobsonian and test it out to see how it performed and also to download and try out Astrohopper, a free open source website that you can download to your phone and use to help you locate objects in the night sky. In this video I'll show you how they work, how to attach them, how to use them, and tell you my thoughts about both of these apps.
