Three Important App Setup Messages:
1. If using an Apple Watch connected to your phone the DEFAULT setting will disable the Notification Sound on your phone and send a ding and a vibration to your watch. You will not hear the Device Sound Check Test #3 notification audio on your phone! To hear it on your phone you must change the settings in your watch to disable Bluetooth, WiFi, and cell service (if your watch has a plan). These changes will make the phone primary for notifications.
2. Android phones keep the phone as the default for notifications in the initial setup. If you are not getting the notification audio to your phone, go to your watch settings and deselect the setting called "Mute notifications on phone."
3. Device Sound Check Test #3 Help. Phone operating systems have made configuring the Notifications too complicated with too many variables. This page provides screenshots to help you configure your phone to get Device Sound Check Test #3 to function properly. Click/Tap Here.

 Written In An Easy To Read Style, Making Things Simple To Understand.
The unique format of this book takes Eclipse Day and divides it into 28 separate essential elements, from arriving at your observation site to leaving at the end of the eclipse. Each of those elements is its own chapter where the information about the astronomy, the science, the observation, photography, and videography techniques are discussed together. The Appendix is organized more like a traditional eclipse book with the following chapters: Basic Eclipse Astronomy, Simplifying Eclipse Photography, Wide Angle Eclipse Photography, Video Recording Ideas, Mistakes I've Made, The Next 10 Total Eclipses.
The book contains 240 photos, 225 illustrations, 175 dialogue boxes, 12 image galleries, 10 embedded videos, 18 audio files.
The foreword is written by Bill Kramer, a world-renowned eclipse chaser and eclipse educator.
(Note: The PDF version does not permit printing but does permit copy and paste, and screenshot capture as an image for printing)

I don't sell eclipse t-shirts, coffee cups, maps, or eclipse glasses.  But I do highly recommend eclipse glasses from American Paper Optics. Click on a picture to be linked to the glasses for a great price on bulk glasses. BUY ECLIPSE GLASSES EARLY!  I'M SERIOUS!
