Alternate uses uses for solar eclipse filters
squarebox:
Is there any use for a ND100000 filter outside of taking a solar eclipse?
The only thing I could think of is doing a super long exposure in the city to remove people.

That's a good thought.
I'm having trouble finding a Photography Solar filter film right now :( I'm trying to get ahold of some of the BAADER AstroSolar Photo film (ND 3.8 according to BAADER). Unfortunately, nobody has a sheet of the thing in stock, although supposedly a few places are going to get some more this week. I found 1 Canadian place that supposedly has some in stock (according to the online part), but I'm going to call and see if they really do, and how fast I can actually get it.
NOTE: The ND 3.8 is for Photography only, NOT for visual use, so if anyone gets some only use the LiveView or similar functionality. Get the ND 5 if you want to use it visually.

Just this afternoon I bought the last Baader filter that will fit the 7" lens hood of the 400 f/2.8. The lady had to bo back to the inventory room to make sure it hadn't been sold to somebody else or otherwise placed on hold.
If you don't already have your eclipse viewing gear, don't expect to be able to find it. Pretty much everybody is cleaned out.
As to what to do after the eclipse? Well, not only are we in an active sunspot cycle, but there's the transit of Venus coming up.
I should add: I'm not planning on using a filter for the money shot. That'll (hopefully) be your typical wide angle sunset-with-sun-in-the-frame picture, except the sun will be a ring, the light will be utterly bizarre, and who knows what that'll do to the Grand Canyon.
Cheers,

True TrumpetPower!, I'm still hoping to get it. Maybe I should just go for the pre-made filters, I just need to measure my lenses.
Do I need a Solar Filter if I'm doing a wide angle (~24-35mm) shot with the landscape? I've got 2 cameras, so one will be setup for that, the other I'm experimenting with the Opteka 800mm mirror lens with the 2x TC to give me ~1600mm close up of the sun. For that, I'm definitely going to need the solar filter. I'll likely make a 'hood' for the Opteka so the filter will stand off from the front element a good bit. Even at 800mm, I can do a pretty deep hood.

You could always photograph sunspots. Wish I was going to be able to see the eclipse, but it's not going to happen. I have my fingers crossed for the Venus transit, I got a nice series of photos of the 2004 transit at sunrise here in Florida. This one will be a late afternoon until sunset event. Shooting through a 2000mm f/10 with full aperture solar filter, the sun will more than fill the frame on my 40D.
