I want to try photographing the transit of Venus across the sun on
June 5th, but I've never tried shooting the sun before. Any of you
guys have tips you can share? Is there a special filter I should use,
or would a polarizer or ND filter be sufficient? I'm planning on using
my K 500mm f4.5, so I'll
Do not I repeat do not point your camera directly at the sun, it will do
the same thing to it's sensor that it will do to your eye. No filter
you can afford will work. There are methods of using something like a
pinhole camera taking the photo of the back reflecting surface, (and by
reflectin
I have a 6 inch telescope that has a special attachment for solar
observations. Basically, instead of looking through the eyepiece, I
focus the light from the eyepiece onto a square of white painted metal
held beneath the eyepiece by a special bracket. I can place a piece
of paper or a card on th

If you are looking for a quick source of some Baader Astro Solar film,
I suggest finding your local Astronomy club and seeing if you can
beseech a kind soul to share/sell a small chunk with you. Many small

My plan is to wait for Thierry Legault's photos and just look at those.
He seems to be the "transit photography expert" in this world.

P.S.: Hey Aussie PDMLers, I loved your country! Just got home last
Friday. I hope I get to go back to Australia soon, especially to see
the outback and more of Tasmania.
Glad you enjoyed your visit.
Hopefully, next time I'll be in town when you're in town

Check out this page for some safety notes when using welding filters:
http://www.transitofvenus.org/faq/354-can-i-use-welding-glass-to-view-the-sun
I'm going to take my telescope to work, and try some solar photography (with a
Baader solar film filter for the telescope) this week, for a bit of pr
To be specific, a No. 14 welding glass (only) is safe. Do not stack
lesser opacities.
If you have a narrow telephoto, like the preset Takumar 200mm f/5.6
(which has a 49mm filter size) you might be able to get by with a
2-1/4" glass (and use a teleconverter).

Thanks for the info. It's been a very long time since I used welder's
glass, and I'd forgotten that different grades were available.

Nice page to calculate local transit times:

Looks like from my location I would get to see exactly 4 hours of a 6
hr and 44 min. event before the sun sets.

Yeah, I looked it up on Boz's site and not only are there no front
filter threads (which I knew), but the ou

You can always watch the transit here:
June 5: Venus Crosses the Sun
On next Tuesday, June 5, from noon to almost 7 pm HST, Venus will
cross the Sun for the last transit until the year 2117. It's the final
time anyone alive today will have a chance to see this rare
astronomical event and the Isla
