This photo is attempt to capture the Sun and its Corona in situ restoring the Solar disk to the Corona in its starry setting with Regulus glowing the lower left.

Your Equipment: Vixen VSD Astrograph (380 mm F3.8) mounted on an iOptron Alt AZ with a Nikon D500 camera. Equiv FL 520 mm

Your Data:Location a farm in Idaho 43 51 05.80 N 111 26 53.94 W that had 2 min 11 sec TSE

Your Processing: This is a total of 10 images, One white Light image captured just before C1 to capture Sunspots and Solar disk and 9 images captured as an HDR at ISO 200. The resulting images (NEF) were converted to TIF with Photoshop, the white light image optimized and the solar disk cut out to place over a HDR (Photomatrix Pro) of the Corona/Sun/surrounding space also processed to TIF and adjusted with Photoshop. The combined composite then flattened and adjusted for posting.

Equipment:

Orion ED80T CF at f/6, Orion field flattener, Canon Rebel T6, Celestron Evolution mount (chosen for simplicity over polar aligning an equatorial mount during the day).  I controlled the camera via Backyard EOS.

Processing:

This is a blend of 14 exposures, ranging from 1/4000 of a second at ISO 100 to a half-second at ISO 200.  Pre-processed each frame in Adobe Lightroom, and then blended together in Photoshop CC as a Smart Object.  I think I used "Mean" mode for the blending.  Then I tweaked the stack further with the Camera RAW filter to taste.
Location:

Land Between the Lakes National Recreation Area in southern Kentucky (about 20 miles as the crow flies from the point of greatest eclise), 2 minutes, 18 seconds of totality

Equipment:

Canon EOS 70D at TS Photoline 60 mm f/5.5 - FPL-53 apochromatic refractor with flattener

Tracked by Skywatcher StarAdventurer mount on carbon tripod, no filter

Controlled by Eclipse Orchestrator software via laptop

 

Data:

Location: Total Eclipse Camping, between Mitchell and Service Creek, Oregon

Exposure: Composite of 39 images with exposure times from 1/3200 seconds to 4 seconds, ISO 200

 

Processing:

At first, I calibrated the single frames (dark frames, flat frames for images with exposure times longer than 1/30 sec exposure time. Then I applied the Pellett method (with a radial blur filter, amount: 10, method: spin, quality: best) as described by Jerry Lodriguss on his website, by using Adobe Photoshop. And then I additionally applied the Larson-Sekanina-Filter with Fitswork (5 different versions with radius 0.5 pixels and rotation 1, 2, 3, 4, and 5 degrees, respectively). I multiplied each of these filtered results with the original stacks. Then I removed artifacts (2 dark spots next to each brighter star) with the clone stamp tool in PS and stacked the 5 images together.

Then I created another composite of 2 images with 1/2 sec and 1/15 sec exposure time, extracted the moon's "disk" from that exposure, enlarged it slightly, and pasted it onto the TSE composite image.

The whole procedure with several intermediate steps (and a few alternative versions not included in this contest) is documented here:

Summary of software used: Fitswork, Adobe Photoshop

Your Equipment: Takahashi FC-100DF, Avalon M-Zero, Canon 6D
Your Data: 30 exposures from 1/125 sec to 4 sec., 21/08/2017 - Cedar Hills Vineyard, Ravenna, NE.
Your Processing: Processed in Pixinsight: Dynamic Alignment, HDR composition, Masked Stretch, Larson Sekanina, HistogramTransformation. Minor blemishes corrected in Photoshop.

 

There were high clouds which washed out all the detail from the Moon surface and made general image processing quite hard! I have used a black mask in Photoshop to cover the Moon.

My humble offering - click on it for higher res.

 

I was able to record polarisation in the corona by shooting two back-to-back sequences, short to long, flip polarisation then long to short. The sequences were processed individually then false coloured and superimposed.

 

Polarisation V5

 

Images shot from Lost Springs, WY.

 

APM 115/805 with Tak TOA130R reducer and a Canon 5D Mk II. Everything carried by my AP 900GTO. The scope was fitted with a home-made adapter and a polariser from my camera so that the effective aperture was about f/6 and T/8. The trip and my processing were covered in a special edition of Nightfall.

Sorry for the late response on getting the winners posted. Was a busy weekend for me.

 

The winner is Robin! Congratulations! You did a great job balancing the corona as well as getting both the neighbors in on this shot :)

Great job, Robin! Love the striations of the corona radiating from the sun's magnetic pole in your shot! I actually saw this with my own eyes through my telescope, but could not capture it as well as you did through my camera. It was my first total eclipse and I learned a great deal. With lessons learned and if the Lord agrees, I will do much better for the 2024 event.

 

Congrats!

Mel

Thank you very much for the nice feedback! :-)

I spent a lot of time on the preparation for the eclipse trip last summer. Many hours for an event that only lasted for approximately 2 minutes... And I really must say that I learned a lot about eclipse photography and image processing on this forum.
