The Simple Observing Log (TSOL) was designed as a place where you can monitor and keep track of all your star-gazing information.

You may fill out forms for all the objects you intend to view in a session, then use the forms to keep track of your sucess, or you may observe as you always have, and record your observations during or after your session. After you're done, you can view and print your observing records sorted by date or by object.

There's even a space where you can sketch your observations on the page, or place scans of your sketches after you're done. An "astrophoto" section for each observation lets astrophotographers keep track of their exposures as well.

When you want to use TSOL in the field, simply choose "Nightvision Mode" to switch to a vision-saving red display
