Ok, there is going to be a total eclipse visible across most of the US on August 21st 2017. (It's a Monday)
I want to photograph it.
The path of totality closest to me is from NE Kansas passing north of KC heading generally SW across MO passing south of St Louis. I consider that to be mostly in "day trip" range.
Anyone in the path of totality willing and able to host me and my camera for a couple of hours?
Edit to correct date/
-
Welp, that guarantees that there will be absolute monsoon rains in Northern Virginia that day.
-
Northern Virginia doesn't get to play with totality anyway.

Not total in CO. This interactive map might be helpful to those willing to put you up:

You might want to start looking at hostelries in that path to reserve a place looong before 21 Aug 17, then cancel out if some APS denizen can put up with you put you up.

I'm not sure how to read that map...
Does it show the totality zone, with lesser percentages visible to north and south, or does it mean the eclipse is only visible in that zone?
-
We are directly in the zone of totality. Should be exciting. Even if it's cloudy it will get really dark.
I witnessed a partial or total eclipse, i'm not sure which, in South Africa in 2002. I remember that it happened but for some reason have no memory of the actual event. So I'm looking forward to it.
-
I saw a partial in 1992 or so here in Northern Virginia.
Maybe 15%.
Not very amazing.
-
I'm not going to be in the path of totality, I'm slightly too far south living in KC. However, you're welcome to pop in here if you want. Take a nap, get refreshments, etc. =)
I've been debating heading up to St. Joe to check it out myself.

I saw a total or near-total eclipse in the late 1990's in Rochester, MN. I didn't know about it until a couple of hours before, so had to make a dash to the welding supply store for some filters. They didn't have any #14's; I think I stacked a 5 and an 8 and still had to squint.
-
I'm usually in Idaho that time of year. Even the correct part. I'll need to put this on my calendar.
The last time I saw one, I didn't see it because it was fogged out.

So, I shouldn't use my binoculars?

Missouri ranks #1 of the states in the path, with 3.4 million of its residents living directly in the path of totality. St. Louis has 1.6 million residents living within the path of totality and is tied with Nashville for the most [sic] number of residents living directly within the path.
Looks like we'll see it about 1 pm, and my workplace is a block or two from "totality."
-

I've read that a #12 welding filter is sufficient, but it's really not. Perhaps because my eclipse was not quite total?
The filters are cheap and the numbers are additive; buy an assortment and stack them to add up to about 14 or 15. Take a peek, and adjust.

The last really nice eclipse I saw was on January 4th, 1992. I was in San Diego so we ran up to Ft Rosecrans National Cemetery. It was an annular eclipse that happened at sundown, pretty neat. I knew nothing about taking pictures of eclipses (still don't) but I dragged my OM10, tripod and filters, GF and kids up there anyhow. Somehow I actually got a decent picture or two.

I wonder if the looters have started making plans for totality yet? =|

Guess my memory of eclipses is off.
I thought there had to be a full moon to have an eclipse and the full moon for Aug 2017 is on the 7th.

Ummmm..... the moon is the same size whether you can see all of it or not. Phase of the moon has nothing to do with eclipses, it is all positioning of the moon, earth and sun.

Interestingly, North County (Ferguson-land) is outside the path. Only the south side will go dark.

Not sure if serious. I don't think he said the moon changes its size.

Can't have a solar eclipse and a full moon. During a full moon, the moon is (roughly) on the opposite side of the earth from the sun, and thus couldn't obscure the sun. Solar eclipses can only happen with a "new moon", as that puts it between the earth and sun.

Full moon for a total LUNAR eclipse. Earth's shadow hits moon.
This is a solar eclipse. Moon's shadow hits earth.
Went up to Maine in the 1960s to catch a solar. Camped in the woods by some river, Kennebec, Kennebunk? Partly cloudy, so photography not so great.
Weird thing about it was how all the birds quit chirping during the time of totality. It was darned dark pretty suddenly.

The darkest I can ever recall was in the middle of nowhere Montana with zero light pollution during a total lunar eclipse. I could not believe how dark it got during the totality part.

For the link I posted for the 2017 one, the instructions are rather detailed and complex as far as durations, maximums, and locations, etc.
^^ Mine was this one:

Future Wife1 and I and two pals went up there for it.
Amusingly, she has movies of the campsite and all of us puttering about which I viewed with Son2 via digital copies of the 8mm movies. One of his comments was, "Mom was sure beautiful!"
She still is, actually. My comment was, "Yeah, yer old man knew how to pick 'em."
I still love that old broad, but don't tell anyone.

Not true. Think it out.

Heysoos Aitch Kreist, don't follow this advice. I know he's kidding, but...
You can project an image of the eclipse onto a screen using binocs or a scope, but looking at the eclipse directly through a scope or binocs without heavy filtering is dangerous. Sunglasses won't cut it, hence the remarks about heavy ND (Neutral Density, i.e. colorless, or gray) filters from a welding shop.
The screen itself may start to smoke before totality, too, depending on the optical device used to project the image.
You can also use a pinhole camera-like (look up camera obscura) arrangement to view the proceedings, but resolution of the image may not be the greatest, depending on the size of the "pinhole."
Around the times and locales of the eclipse, local media will give plenty of warnings about all this, but some folks just won't get the word.
It takes quite a bit of coordination and rehearsal WRT viewing devices, when to insert and remove filters, etc, etc, to capture a full solar eclipse adequately.
The business about "stacking" ND filters is good, because the available light becomes less and less as the eclipse approaches totality, and you can rapidly remove filters (with rehearsal) as it approaches a full annular eclipse.
By way of definitions, "full annularity" is the center image, courtesy Sky and Telescope magazine:

See my dad always said the mind was the second thing to go....just could never remember the first.
Thank you,

Yer welcome.

Quite possibly, since the least amount of light is in a full annular eclipse.

Of course it does.
There's a very intricate system that inflates/deflates the moon on a regular cycle.

I see an eclipse every day: an Earthly eclipse. Starts at sunset and ends at sunrise.

Being on the darkside of the planet during a diurnal rotation is not an eclipse.
It's called night. :P [popcorn] :rofl: ;)
