    Default Solar Eclipse in Corvallis, OR



    Here's my attempt to recreate the overall experience. Images were taken through a 400 mm f.l. tracker scope on stationary mount with Olympus E-510 at prime focus. The solar filter arrangement made this effectively f/9. Exposures were 1/125 sec, about 10 minutes apart (though I took images about every 5-10 seconds at totality!) It was a truly wonderful experience. One of my friends, who saw this first total eclipse after having over 40 years of experience with astronomy, reported, "my brain fried!"

    I've included two versions - one with the sun at proper scale with respect to its path through the sky during the course of the eclipse, the other with the sun enlarged four times with respect to the scale of the positions. It always intrigues me that even though I know the image with the small suns is "correct", the brain's insistence that the sun (and similarly, the moon) is much larger in the sky than it actually is, makes the image with the zoomed sun images seem better. Planetariums usually project the moon about 4 times larger than life-size so that it seems correct to the audience!

    Nice composites, wvinton! Interesting tidbit about planetariums projecting the Moon at 4x - must have something to do with the Moon illusion!

    At first I was thinking the diagonal was oriented wrong. I keep forgetting it was a morning event for folks on the West Coast, while it was an afternoon event fro us in South Carolina - I'm better now. Thanks for sharing - brain fried indeed!

    It would be interesting to me to assemble a set of images of roughly the same point in the eclipse from places on the Far West Middle West Central Middle East and East to see the different orientation.

    FYI, I determined the alt/az of the sun at different times during the eclipse with the location set at my observing site in Corvallis (I used SkySafari), made a graph of the alt/az in Excel with equal scale on x- and y- axis, and then used that as a template for placing my images...

    Very cool! Thanks for sharing it. The perspective helped me too with the (poor) images I did take. I have several frames that includes shots that look like yours surprisingly, but, appeared almost as a reflection. Not sure why that was and it comes off as a double exposure. I enjoyed looking at yours!
