I went to the local welding shop and they had a display for 3x5 pieces of glass for welding helmets setup that is safe for viewing the eclipse. I bought a couple of them as they were only a $1.65 each. It was a sunny day so I stepped outside and held it up and looked right at the sun with no issues.
Just an option I think.

Just finished a solar filter for my Sigma 150-600. Bought a 95mm - 105mm step up ring. Taped and glued Thousand Oaks solar film between two rings cut from foam posterboard (less messy than cardboard). Glued it into the step up ring. It looks like it could fall out, but the first piece of posterboard is snug (and glued) into the ring. I'm pretty happy with the results. It looks a lot better than the filter I made for my 100-400.

I have a quick question, if i plan on shooting more of a landscape will a regular ND filter be needed? im not pointing the camera at the sun, just will have that in the background. If i have say an 8 stop ND filter?

Im planning on using the Canon 24-70

can't imagine why you'd even need or want the filter. I'm going to have one camera set up with a wide angle getting the darkening landscape so I'll just have it set on one setting, for the most part and get the whole sequence.

Only necessary if you are pointing directly at the sun

I'll see about 88% coverage, so I'm not taking this too seriously. A few minutes and a $12 DIY filter is all the effort I have for this. Plus 70-200mm is my max.

Anyway, here's a quick handheld test. Not sure I'll even bother with the tripod since I'll be at work.

200mm and a pretty hefty crop.

How much of a crop was that?

Maybe my 70-200 won't be be enough -?

200mm is enough to get a decent shot... especially if there are a few clouds in the foreground which can enhance the image. For instance, the shot below (which is featured on the cover of the current issue of NEBRASKAland magazine :-)) was taken with my 70-200 f/4L at about 180mm (by accident... it was meant to be 200mm!) back in 2012. It's been cropped a bit, but still looks OK.

It was at 6:38am on November 14th 2012, about 1 hr after sunrise, with the Sun (and Moon :-)) 14 degrees above the horizon.

Can anybody provide a link to what I'd need to shoot the eclipse with my 500 f4? I have safety glasses but I'm thinking of shooting it too. Thanks !!! Obviously I'm probably limited to amazon at this point to get something in time.

1 -- Thousand Oaks 77mm threaded filter on a 5D3 cropped from 400mm 5.6 non-IS, at ISO 100, f/5.6, 1/640:

2 -- Cropped from 400mm with 1.4x TC, ISO 100, f/8.0, 1/320

IMAGE: https://photos.smugmug.com/photos/i-tGKSqrj/0/36491ea1/X2/i-tGKSqrj-X2.jpg

The above are 1:1 image crops. I'm not able to discern an IQ difference when I look closely. Can you? I'm thinking of ditching the 1.4x TC to allow for nine focus points vs. one if I use the TC. I'll take focus with auto, and then switch to full manual focus using gaffing tape to lock my lens at infinity for subsequent shots. The 5D3 at f/8 allows only the one center cross-type focus point, unfortunately, which can get tricky when it is that dim.

Another consideration is how wide the corona might become during totality. With the TC, I might miss some dimmer tendrils at the boundary of the frame, as they can sometimes be seen eight solar diameters out (when bracketing).

I have a question for you....I've been practicing with a solar filter...using my 70-200 with 1.4ext on a 7D body for crop factor help. My test shots of the sun have come out white. Nothing with the color tint you show here. Am I not shooting fast enough?

They come out white because of the type of filter you are using. In post processing slide the color temperature warmer until you like the color of your sun.

Edited to include pics. First pics is SOOC second pic is cropped added clarity 35% and slid color temp to make image warmer.
