Re: Eclipse photography

I finally found a well-written and thorough discussion of solar photography and filters. It's on Canon's web site but is very much brand agnostic for the most part: http://learn.usa.canon.com/resources/articles/2017/solar-eclipse/solar-filters-eclipse-photography.shtml -- PDML Pentax-Discuss

Re: Eclipse photography

What i have done in the past is to use 2 polarizing filters and cross polarize them. 1st one (closest to sun) must be a non circular type. Done it this way as i am cheap and is all that i have. Also good results can be had with a welding glass. How you mount it however is entirely up to you.

Mine is a Sigma 300mm F2.8 EX APO in Pentax KAF mount. It's the last of their film lenses in that focal length, before they reformulated for digital. It has a detachable lens hood that reverses when it's in its case. Measuring across the outside of the lens hood it's 129mm. The Astrozap

Re: Eclipse photography

John, I'm thinking of getting this too. Is yours for the A *300/2.8? Thats what I'm going to use and haven't had a chance to measure the outside diameter of the lens end. On Tue, Jul 11, 2017 at 11:02 PM, John wrote: > On 7/11/2017 21:54, Mark Roberts wrote: >> >> I

Re: Eclipse photography

Hmmm, let me think. Scores of highly skilled photographers from all over the world will be shooting the eclipse, and their work will be displayed everywhere. Should I drive 8 hours to add my undoubtedly less than stellar image to the huge pile? Uh, no. Paul via phone > On Jul 11, 2017, at

Ran across this map on Twisted Sifter. It gives average drive times from locations in the U.S., Canada & Mexico to the center-line of the eclipse path. http://tinyurl.com/Aug21-Drive-Time On 7/11/2017 21:54, Mark Roberts wrote: I expect there will be more than a few of us attempting to

Re: Eclipse photography

Just as I was heading out on my road trip B sent out an eclipse mailer: https://www.bhphotovideo.com/c/solar-observing/ci/33818/N/3583558376/sba When I was in Portland I was talking to my rocket scientist friend Phil about watching the eclipse, he wants to make a camera obscura to project the

Re: Eclipse photography resource

Thanks. I took a look at it & it has some information I can use even if it is a Canon site. On 4/20/2017 10:09, Stanley Halpin wrote: John, others gearing up (pun intended) for the eclipse this August: I just noticed a reference to a Canon site that has tips on preparation for the event.
