The device on top of the 'scope (where the finder scope should be) is a Celestron StarSense AutoAlign. If you haven't the space for a permanent observatory / shed in the garden, then every time you use a telescope with an equatorial or 'go to; mount, you have to spend half an hour aligning it with two or three bright stars and logging these into the mount's memory. Hopefully this new gizmo should do the job automatically: once it's standing on a flat area, you turn it on and it scans the sky until it works out where everything is! Then you just use the handset to navigate and lock on to hundreds of pre-loaded objects. Just need a clear sky now to try it out!
