11 Travel Tips for Participants Valid Passport --- good for at least 6 months after dates of travel. Australian Visa is mandatory, can be obtained online with your ticket #. Bring a modest amount of U.S. cashmajor credit cards accepted widely. Pack lightly --- primarily casual clothes. No formal wear necessary.

12 More Travel Tips Bring ample personal medications, and Rx, in case meds are lost/taken. Some venues we visit will have HOT climate, humidity --- dress lightly, with an ability to layer your garments. Remember baggage limits: 2 checked bags per passenger, w/o extra charges.

13 Yet More Tips Take plenty of sunscreen, with SPF of at least 15; SPF of 30 is better yet. Take a wide-brimmed sun hat along. Insect repellant is a must!! Bring spare camera batteries, cable releases, a small tool kit, AC power adapter kit.

14 Equipment Pointers This eclipse is very, VERY brief. Large amounts of hardware are unnecessary. We will be visiting 6 venues --- leave the heavy stuff behind!! Your tour leader will be taking a scope for nighttime observing leave yours home!! Eclipse h/w: 35mm SLR or digital, tripod, wide angle lens/zoom lens, cable release.

18 Photographic Guidelines Again, a very short totality --- be sensible about your objectives. Limit yourself to ~ 6-8 photos max. Advise wide-angle images, not telephoto/narrow angle shots. Practice your routine, with a timer. Bracket, bracket, bracket your shots!

19 More Photo Suggestions Film speed: 200 or 400 ISO. Exposure range: 1/15 second down to a maximum of 2 secs. Anchor your tripod and use centerline weights (sand, water, rocks) in a jug. Do not spend all of totality looking through a viewfinder --- gawk!

20 Yet More Photo Help Digital video cameras (CCDs) should be set to a manual iris setting, not automatic. Preset your zoom factor to yield a wide angle/landscape formatted scene. When panning around the horizon, move slowly and use a steady motion. Fluid head tripods are best for this.

24 Eclipse Etiquette HUH??

25 During Totality, Please Don t: Use any white light sources. Use your strobe/flash on your camera; disable it completely/cover the lens!! Run amok at the viewing site and disturb others while they are observing. Play obnoxious, loud music (> 60 db) that would disturb your neighbors.
