There is a wonderful opportunity coming up in August of this year. A total solar eclipse doesn't happen over populated areas very often. If you get the chance to make the journey to the narrow path of totality, I would urge you to take advantage of the situation and get out there - but be prepared. Of course, never look at the Sun directly, even during an eclipse (one exception, buried in the first link below). Special solar viewing are mandatory, as well as special filtering for cameras, telephoto lenses and telescopes.

I have assembled some resource links below, and will update and add to them as I find them. Feel free to place useful links in your posts below. If you have your own photos of solar eclipses from the past, please share them too (only your own photos please). If you embed or link your own photos, adding pertinent EXIF data and what type of filter you used would be most helpful.

I plan to road trip myself and camera gear to a western part of the US where the chance of cloud cover will be much less than Carbondale, IL. The Carbondale area has the distinction of the longest viewing time of totality (2 min 41sec). Oddly, the 2024 Solar eclipse path also comes through Carbondale. The party will be there, if you like big crowds and what will be sure to be a media frenzy. While that's the closest to me, I prefer less crowds and less chance of clouds.

Solar viewing Filters for photography? Have one? What type? (An ND10/400 won't do, BTW). If you'd like, give examples of your equipment and setup for solar eclipes. We'd all love to learn from your past experiences.

Do you plan to be in the path? If so, where? Maybe we can get some eclipse photo parties going.

I looked through both the cardboard and higher quality plastic pair, and the Sun was orange with either.

    Thanks for posting this, David! I was out with some folks from my photo group Saturday, and we were talking about shooting the eclipse. I'll probably be somewhere in South Carolina or the mountains of western North Carolina. It will be interesting to see what everyone comes up with.

    I live very close to American Science and Surplus, so luckily I can see and touch their products in their Geneva store. They currently have a ton of stock of Solar Eclipse viewing glasses, both the cardboard type and the less-nerdy heavier duty black plastic "sunglass" style. The price of their cardboard model is less than $2. I don't think you can beat that. I looked through both of those at the sun directly overhead out their front door. The sun was orange tinted. There are some glasses out there that will make the Sun appear blue-grey, effective perhaps, but the color is weird.

    Discovery Number 1: I was prepared to pop for the more expensive ($15) pair, but the sun appeared blurry. Well, that was a moment, since I wear glasses. So I decided to buy a couple pairs of the cardboard type, cut the front elements out and tape them to spare pair of prescription glasses. That way, I can actually see the eclipse, if I am not already buried behind my camera changing the settings.

    Thousand Oaks sells photography supplies dedicated to solar eclipses.

    There are several interesting locations that will be in the "zone" that might be worth considering:

    The Grand Tetons. You can bet this will be packed with people, but still.
    Just the edge of St. Louis (this might not work well, but imagine the eclipse with the Arch in the shot).
    Charleston, SC is on the very bottom edge but with so many cool sites this might be worth some consideration but do your homework to make sure that you'll get the eclipse.

    Once you know where you'll be (and the local time of the eclipse) you can you this site to match up the sun with any interesting buildings or mountain or whatever.

    Good links! Thanks. There's also the Photographer's Ephemeris, a free desktop app, and also a phone app. The Sun will be largely overhead this year during the event. Not much horizon/eclipse shooting this year. The Arch is a good idea -- but one potentially several thousand photographers and i-phoners will no doubt also come up with at the last minutes. Could be a zoo. I expect a general migration of masses of people towards the primary total line almost everywhere in the country. That's why I want to be in the middle of nowhere, but near something interesting nevertheless, just in case the eclipse is a bust. 800 miles of driving I should have a plan B.

    I've only been to one previous total solar eclipse, Zambia 2001, and it was well worth it. Here are a few thoughts:

    1. Book a place to stay -- now! Thankfully, our country is really big with nice infrastructure, but many good spots have already filled up, I'm sure.
    2. Don't count on air travel -- get there early. Flights will be overbooked as normal, but no one will be willing to give up their seat, so there will be issues.
    3. Get your solar filters and lenses early. Shortages will happen! Though eclipse glasses tend to be available pretty late.
    4. Test your equipment before the event! Most folks here don't need this reminder, but snapping the sun is pretty easy to test.
    5. Have a backup plan. If it rains, can you drive somewhere? Will the roads accommodate all the traffic trying to divert?

    You can get welder's glass which is dark enough to safely view the eclipse. It's pretty cheap, BUT, it's not optically straight, so photographs will not look that good if you stick one in front of your camera.

    We have family coming internationally to view it, so we've booked our place to stay in Driggs, Idaho. It's just outside the Tetons, so even if nothing good happens with the weather, we can visit a nice national park (along with thousands of others, probably)!

    Just ordered a 77mm filter through Thousand Oaks. $59 plus the $10 shipping/handling chg.

    Has anyone here used a threaded solar filter on a lens before? My worry is that I won't be able to live view through such a dense filter. Looks like this is 1/100,000, or roughly 16 stops. Yeesh!

    Since this is a multi-hour event, I will need to (manually) point the rig towards the sun, and adjust it every few minutes, fully filtered. I don't have a telescope guider. Might this be a problem? Easy solutions for manual alignment?

    Yes, I am planning on testing the filter in the next few weeks after it arrives. I will report back with results good or bad. I'll be using my Canon 5D3 and a 400mm Canon L 5.6 lens on a firm tripod with a ball head.

    Live view works great with a threaded solar filter! It's almost mandatory to be able to get a sharp edge; magnify and focus. Though I haven't used it with my 7D2 yet, the 50D definitely struggled with autofocus. I'm not going to be using a guider either, as long as the Sun isn't taking up the whole sensor, it's easy enough to re-orient and shoot. Up until close to totality, it's fairly relaxed (then it can get crazy).

    You may want to think about a TC with that 400mm lens, especially since you're full frame. I don't have them yet, but I plan on having 1.4TC along with the 100-400 zoom. That gives me about 896mm of effective focal length, which is a little more than half the frame.

    FYI, I ordered my 77mm filter from Thousand Oaks back in January, and it still hasn't shipped... possibly because of high demand for the annular eclipse this past weekend? So expect a little bit of a wait! Oh, but it was the glass version.

    I asked about glass filters as the first question, as I remember seeing them on their site a while back. They mentioned there is no glass 77 thread-on filter option anymore. The website also currently has no mention of glass, except for scopes. You might want to call and check on your order if you're waiting. They told me 10 days for the solarlite filter. I also asked what material the ring is made of and she didn't know that either. So it could be aluminum or brass, or ???. Hopefully not plastic! I was told I'd receive email when it ships and my card is charged.

    I do have a Canon 1.4x TC, but the 400 L 5.6 is slower to focus with it on. Heck, the almost 20-yr. old 400 5.6 is slow focus on it's own accord, even with the 5D3. I've never thought the files were any better with it on or off, when cropping, but during trials I'll be sorting it all out with, without, etc.

    Good to know you've been able to live view focus through a 16 stop filter. It's difficult enough with my ND400, which is 9 or so stops.

    My older screw on filter was made of aluminum, but I bought it 8 or so years back.

    opticalinstruments has some 77mm screw on filters made by Thousand Oaks.

    For some odd reason, they make you use the search button to find this filter instead of listing it under filters.

    Two weeks, and no email confo from Thousand Oaks. @ChrisJ, have you had any luck with your 2 month old order?

    Hi @David_S85 , I got worried at your last message... but I received my order today with the 77-G and another filter for my small telescope. Whew! Maybe I got part of the last batch?

    I have a much older non-glass (black polymer?) filter from them, and it has a metal ring, aluminum I think. It's still in good shape and usable, but it's only 58mm. So now I don't have to play with step-down rings!

    Glad for you it finally arrived. Maybe they're just getting backed up again. If it goes another several days I'm going to call and check in with them. I really want to experiment and test the system together.

    My filter arrived today, though I never got an email about it being shipped or charged. The ring is aluminum and screws on very easily onto my 400. One side of the filter is black and the other side looks to be some dull reflective material. Now I need to wait for a sunny day and test it with the 5D3. It weighs almost nothing.

    Woo hoo! I still haven't had time to test mine yet, either. Hopefully this weekend! The rain is supposed to clear out after Saturday...

    Testing, testing.

    It was warm and sunny this morning, so I did a quick handheld test with the Thousand Oaks Solar filter. 5D3, 400mm f/5.6, ISO 400, 1/1600. Full manual except for focusing. I used live view. Pointing was relatively easy and autofocus worked at 16 stops below daylight! I was hoping to see a sunspot, but none were present today.

    CORRECTION: There is a sunspot, though small, at the 0 o'clock position and 30% in from the edge. I confirmed this with spaceweather dot com.

    Next test will be with tripod (heavy weight below center column), manual focus at ISO 100 and with 5 or 7 shot bracketing to simulate what I might do at the actual eclipse. Target exposure will be ISO 100, f5.6, 1/400th.

    Not one hotel available within 125 miles of the centerline now. Sleep in my car?
