The closest star to our home planet is Sol, our sun. I know it looks big in the sky but just how big is it? It has an approximately 1.39 million kilometers diameter. How big is that? You could fit 1 million Earths into the Sun. It is believed that Sol formed approximately 4.6 billion years ago. The sun produces energy through nuclear fusion, fusing 600 million tons of hydrogen into helium every second. This energy radiates outward with only a small portion actually impacting Earth. A pastime time of observers is to track Sun Spots. These are dark spots on the surface of the sun where it is cooler than the area around it. They occur when the Sun's magnetic lines get twisted and push through the surface. Because these magnetic fields block the regular flow of gases from the Sun's core the surface at those points cool. So how big are these sun spots? They are the size of our Earth and even larger at times. Be careful if you wish to observe the Sun because I do not want you to burn your retinas. There are special lenses and even special telescopes made for observing it safely. 

One of the challenges that some Seestar users have is finding the Sun. You think a giant ball of fire would be easy to be spot, you would be wrong. The Seestar will glide right past it and say it could not find it. The solution is a Sol Seeker, the white part you see mounted to the S50 here. The solar filter that comes with the Seestar snaps right into it and it slides right onto your Seestar. No adhesives or mounting hardware required. With this in place it was just a matter of moving the Seestar with the joystick function of the app until I saw saw the sun hit the target on the back of the Sol Seeker.
