Solar Eclipse - March 20th
Discussion
I'd love to try photographing the solar eclipse in a few weeks time, but I'm unsure as to the best way to get good results.
Clearly nice weather is needed, but given that what's the best approach. Thought of using the trusty Nikon with a Sigma 150-500.
I'm also unsure as to which type of solar filter is needed - any experts on this subject?

I was going to try this too, was planning to use a 500mm f4 and putting a 10stop ND filter in the drop in filter section. Something like this....

It is only a partial eclipse where I am, which makes me very worried about overheating the filter/lens..anyone done this before ?
Also it is early in the morning so the chances are it will be affected by clouds/fog.

Well this is interesting.

Gives the maths to calculate the heat generated by different f/stops and focal lengths.
Turns out about 12 watts for a 500mm F4......I am guessing this is going to quite a lot of heat, too much for a raw sensor and needing to be filtered.

Wind may scupper my plans, but cloud cover won't :-)

You just need to make a filter out of Baader AstroSolar Safety film (or similar). It is designed for solar observation with good optical qualities and blocks 99.999% of UV and IR radiation. You can pick up an A4 sized sheet of the film for about £15-£20 from good telescope suppliers and comes with details on how to make a filter.

This is good information, I have been googling this morning, and Baader film is definitely the most recommended, and it seems ND filters don't block all IR light which means they can be dangerous. And it seems it would be better ( for me ) to block off the entire objective of the lens rather than drop in filter.

What about using live view to do the focusing etc - no danger to the eyes but can you burn out your sensor?
Not only can it burn out the sensor but possibly lens internals (iris) too (could also buckle the shutter if you come out of live view).I think I used welding glass for the last eclipse (gives a green colour cast though) but I've invested in the Badder film this time around. For totality you don't need any filter but we won't be getting totality in the UK this time.
To be honest the most interesting photos of the eclipse are the shadows cast by the partial eclipse. As the light source (sun) becomes cresent shaped the tiny gaps between leaves in trees etc. all act as pinhole cameras casting cresent shapes on the ground e.g.:

Unfortunately everyone seems to look at the sun and forgets to look at their feet for this interesting effect.
just realised I'm staying in the Shard Thursday night in a city facing room, so will be there for the eclipse.
How do I best capture this from a scenic perspective, over the city, rather than taking a picture of the actual eclipse.
how do I set the exposure?
Do I either set it according to the light at 8:00am and use a manual metering or should I place it on auto metering that will alter as the light changes?
I hope to set my D7000 up for a time lapse for say 3 hours 8:00 to 11:00 (taking a pic every 10 seconds and playing back @ 5 fps giving a 3 1/2 minute clip, if my maths is right)
thanks in advance for your advice

Just set focus to infinity.FunkyNige said:
