Please consider using an alternative browser - especially if you are on Windows XP which only supports the outdated Internet Explorer 8 browser - such as Google Chrome or Mozilla Firefox which do have support for these web standards. As well as not supporting modern features and web standards, old versions of browsers - especially Internet Explorer - can expose your computer to security risks. The Browse Happy website has a list of the latest versions of all major browsers, including Internet Explorer (but remember Windows XP only supports up to IE8!)
If updating/changing your browser is not possible, do not panic - all of the LAS website is still available to you and we are working to make the layout compatible with outdated browsers.
Once the sun menu is enabled you can either press enter to go to the sun, or when the unit is turned on press escape and manually move it to the sun. It will then track.
Because it is not aligned on any star it will get somewhere close when you press the go to. If it does not actually get the sun it will probably be in the finder. I use a homemade Mylar cover for the finder (the finder is a 9 x 50).
