Celestron 80mm Guidescope Package
With the Celestron 80mm Guidescope package you can easily track stars throughout the night. First of all, you focus on a star. Then you adjust the telescope. Now it is very easy to keep tracking the star of your choice because of the double perspective.
The finderscope is indispensable for astrophotography. Especially when dealing with longer shutter times, you really cannot do without the finderscope. As the stars arc across the sky at night, the camera will have to be moved along to keep the image intact.
