I'll spend the night at the home of friends who live in Goose Creek, S.C., just north of Charleston. Their back yard is comfortably within the totality zone.

Wade, don't use the new camera for the eclipse unless you put the appropriate filter on the lens. Else, looking through the finder you will lose the sight of an eye, while simultaneously destroying the camera. It takes only milliseconds after the end of totality, and you can't react quickly enough to save yourself. Take pix of the people you're with. Take pix of the cute duckies waddling across the road. Take pix of the kittycats freaking out. Don't take pix of the sun.

I likely won't even try. I certainly won't be photographing anything that requires protective filters to look at.

We will have about 2:15 of totality. I been told that the corona (and all that other stuff) is about as bright as a full moon and of course is safe to look at with unprotected eyes. And cameras.

I suspect though, that since the lens only goes out to 280mm (35mm equivalent) that my images of the totality event will be puny and unimpressive. And there will be many online images I can point to and say "Yeah! It looked just like that!"

So you think if I limit myself to the first minute of the event and put the camera away I'll be safe?

****

On edit: I just checked pricing on a 58mm diameter solar filter and $60 or so is to rich for me, especially since NASA will be making much better pictures than me and giving them away. That and the aforementioned puny composition. That's just too much for a filter I'll use once.

I do have an older Fuji digital camera that I may take and put on a tripod to video about 5 - 10 minutes before/after the totality of peoples reaction and let folks see just how dark it did get. That might be fun.

Once I see the event with bare eyes though, I'll be mindful of the clock anyway as I'll be putting the goggles back on right about the 2:00 mark to catch the "diamond ring" effect.

Yes, that's correct. What people do sometimes, though, is get so involved with the corona, and their telescopes, and their binoculars, and their cameras, that they lose track of the time -- 2:15 can fly by -- and they're looking at the lovely corona through, say, a 50mm-diameter objective when the sun starts to come back out. That 50mm objective is rather larger than their eye's pupil is (perhaps 4mm max) and gathers about 300 times as much light. Bingo, no retina any more, and no more looking at pretty faces. Ever.

It happens to someone, somewhere, every eclipse, and it ain't worth risking.

Ten million people, and NASA too, will be taking pix, and surely some of them can take better pix than you or I can.

But I have a pair of filters for my binoculars (Fujinon 7x50), and I'm not gonna take them off during the eclipse.

Where we will be at Lake Hartwell State Park we will have about 2 minutes and 15 seconds of totality. Fair Play appears to be the closest community just a few miles to the east of the park. You can check out the path for SC here: http://www.eclipse2017.org/2017/states/SC.htm If you want to look at other states in the path just change the state abbreviation in the address.

I read somewhere you want to be facing west, or slightly northwest now that I think about it. You will see the moons shadow approaching (at about Mach 2 or 3, I'm told) when totality begins and the the approaching light as totality ends.

Only visible for a second but worth seeing. I guess well get out a compass (I always carry one for finding off-the-air TV) and scout out a good westerly spot.

I found this webcam that's located on the Clemson U. rowing team building at Lake Hartwell. Gives some idea of weather conditions.

http://www.clemson.edu/webcams/?q=rowing

I wish it were tilted up just a bit more to see more of the sky. Maybe I'll find some others.

ON edit: This is a good sky shot, but 28 miles away in Anderson, SC.

I collected this time of event data for Lake Hartwell State Park.

Lat.: 34.4969 N
Long.: 83.0429 W

Total Solar Eclipse
Duration of Totality: 2m11.6s
Magnitude: 1.007
Obscuration: 100.00%

Event Time (UTC/Z)
Start of partial eclipse (C1) : 17:08:07.3
Start of total eclipse (C2) : 18:37:16.9
Maximum eclipse : 18:38:22.8
End of total eclipse (C3) : 18:39:28.5
End of partial eclipse (C4) : 20:02:38.1

You can get your own local data from this map:

https://eclipse2017.nasa.gov/sites/d...map/index.html

The map gives you some other data that might be useful for a telescope. But, alas, I couldn't get the data formatting to survive

So, start 1:08pm eastern daylight time and end 4:02pm. I didn't think the total time would be that long. We should have a good view from the east shore of the lake, no trees to block it.

I just got off the phone and talked to Ruth at the park about staying another night. Got extended to leave on Wednesday the 23rd instead of Tuesday. Nearly the entire park will empty on Tuesday and the dump station will be a test of patience that day. There are 115 campsites and about 110 will leave on Tuesday. I told Ruth that was my reason for staying an extra day, she said "good thinking". For a look at campsites here is a web site to look at them. https://www.campsitephotos.com/campg...ll-state-park/

Yes. Using solar viewers it takes about 1 hour 20 min for the moon to begin encroaching the sun until it covers it completely for just over 2 minutes.

I'm planning on leaving Wednesday as well. Just haven't told the park that, yet.

It's not just the dump station line (btw there are two dumps) but all the crazy traffic headed back home. We'll let things calm down a bit before venturing out.
