To use any of these in SNP, just download the file, unzip it to your desktop and then copy it into
the "Sky Data" subfolder in your Starry Night Pro installation. You will have to navigate to the directory
where you installed SNP and then open the "Sky Data" subfolder. In some cases, these will replace an existing
version of the file. ( You can make a backup copy of the corresponding ".ssd" file before you copy if you want
to have a backup.) If you find any more errors in any of these, send me an email (
henry@spacejunkies.info ) and I will fix and re-post.
