Well, I've finally processed my eclipse data, more than a month after the main event!
Taken with a Nikon D610 with the 24-80mm f/3.5 lens at 24mm f/4. The eclipsed sun is an HDR composite of three exposures - 1/250th, 1/30, and 1/4 seconds at ISO 200, and the 1/4 second exposure used for the landscape. Processed entirely in GIMP.
I wasn't originally planning on photographing the eclipse, but changed my mind on the day, looked up an exposure guide, and just held down the shutter whilst watching the eclipse. Needless to say, I was surprised that anything came out at all!
On the full size picture, Regulus is at about 8 o clock of the eclipsed sun, and prominences are visible at 2 o clock and 4 o clock. (Or at least I like to think so!)
Best viewed at full display brightness!

This image I'm presenting here for the Eclipse challenge came so close to not happening. What a tease the weather gave us all here. I tossed and turned all night hoping and praying for clear skies and kept getting up and going outside barefoot to see how it looked. Please be clear just one more time! This would make it 5 clear mornings in a row here on the Oregon coast. That's really pushing it I have to say. At 5 a.m. it looked amazing. Just crystal...Yes! I tried to sleep a bit more but again just tossed and turned At 7 a.m. I ventured out again.. it had started to fog over. Uh oh. At 8 a.m. it looked dismal. Fog below the treeline. Noooo! At 8:59 a.m. with only a few minutes left before the start of it it happened...The fog lifted to blue skies and stayed clear. Thank the stars and maker! Such an emotional ride.
This is what I was finally able to capture during totality. I've captured a few partial Solar eclipses but this was my very first total and the experience was life changing. Just the gradual light change was spectacular but during totality when the temps dropped from from 70 to far down enough for me to be able to see my breath and all the birds to stop chirping and crickets to be heard? Amazing. I was barely able to get a quick glimpse of it with my own eyes while snapping away at only 1 minute 2 seconds where I was but managed 15 hand bracketed exposures in less than 50 seconds.
I used a Stellarvue SV80ED doublet with a Canon full frame 5Dmkiii on an Orion AZ/EQ-G Atlas Pro tracking mount. Everything was done in manual mode and adjusting the full range of exposures by hand. No automation or computer was used at all. I used ISO 400 to speed the exposure times up a bit and shot everything in RAW format.
The final image is the 15 RAW exposures I was able to capture in 50 seconds fused together using Photoshop layers hand aligned and then that fusion flattened and then just slightly edited the shadows, highlights and contrast in Adobe Camera RAW.
Thanks for looking and the opportunity here. I hope you enjoy the results as much as I do.
All the best and look up!

What a ride!!
5 a.m. it was crystal clear.
6 a.m. it was completely fogged over.
7 a.m. it was cloudy and looking like a complete wash.
8 a.m. it looked horrible.
8:59 a.m. whats this blue sky?!!!
9 a.m. it cleared!!!!
Hands down the most amazing event of my life. The chromosphere and corona was glorious!! I hope you all had the chance to experience it. No words but I was able to capture it for you. This was done with 15 exposures using a Stellarvue SV80ED and ATFF2 on a full frame Canon at 560mm and slightly cropped. I hope you all caught it even if it was just on the telly. No words can really describe it.
Let me know what you think of the final results. Look up!
