Here's a very quick look at just one HDR image set from just one of our Dynamic Eclipse Broadcast Initiative sites.  We have something like 40 sites reporting data from the path of totality, and each site collected about 50 HDR exposure sets like this one.  This is from site 33 near Jackman Maine.

 

This is a quick look image where the HDR exposures are roughly aligned (better alignment coming soon) and the average radial intensity of the corona is removed (the actual intensity drops by a factor of 1000x from inner corona to edge of FOV).  

 

Our volunteers all used 40mm Askar FMA180 Pro telescopes, Player1 Neptune-M camera, iOptron SkyHunter mount, and a SharpCap Pro script to collect the data with a laptop.  During partial phases each site uploaded one image per minute (stacked and processed with PlanetarySystemStacker) and during totality each site ran a script to collect HDR coronal image sets.

 

Looking forward to a lot of data processing!

 

Was this this year's eclipse or a previous one.  I didn't see any long corona rays this year in sulphur springs Texas; like I did in previous Casper Wyoming eclipse.

I originally was planning to go to Winchester, but I got an offer to stay at a friend's place in Plainfield west of Indy. I gave up ~ 17 seconds of totality to be able to stay somewhere safe and with friends. We had a beautiful spot on a small lake with very few people around us. I was hoping to be standing on the center line but my choice of location ended up being a very good one. Now I'm planning my next totality to be the one in 2028 Australia. I won't go to the 2026 event because we're planning a trip to Australia for 2026 so I won't have the funds to make it for either the 2026 or 2027 eclipses.

Tom, that sounds like a beautiful spot to watch and photograph the eclipse from; hopefully you got some wide-angle images from there. There ended up being very few people in Winchester also. I rented a camping spot ($50 for the weekend) so I could set up on Sunday to practice and run through to make sure I had everything, and I ended up being all by myself (along with two friends) in the middle of a field outside the racetrack. There were a few people 100 feet or so North of us and a few people maybe 300 feet or so Southwest, so it definitely wasn't crowded. There were more people inside the racetrack, but it wasn't crowded either. Your site by the lake still sounds better.

 

My wife is talking about saving up the money to send me to Australia in 2028 also. Time will tell. I'd have to get some new equipment though; I won't be taking my AP900HDA and A-P portable pier on that trip...

I finally got around to looking at the photographs I took of totality.   I wasn't expecting good results because I was intentionally unprepared.  I was determined not to use my camera; I wanted to ensure I saw totality with my own eyes.  Still, in the eerie darkness, I couldn't help but grab my camera.   I fired off a hand-held shot, chimped it, and I could see I had the wrong ISO setting and was not bracketing exposure.  I looked down and started fooling with my camera for a few precious seconds when I thought: what am I doing?   I'm not watching the eclipse!    I slammed a -3 EV exposure compensation into the settings, took this final photo on a prayer, and put the camera down.

 

It doesn't quite capture the detail I saw, but it's not a bad memento.

The process to get this image made my brain hurt just trying to figure out the best way to create an HDR image using my existing software. First, I grouped 83 different images by exposures into 8 folders. Those folders were stacked using Siril. The 8 stacks were then processed in GiMP using the circular motion blur / subtraction method. Those images were then blended as layers. I tried multiple different ways of trying to get to this end result, and this was the best method I came up with. I think the thin whispy clouds that were floating through Russellville, Arkansas might have contributed to my having problems. It seemed like every time I tried stretching an image something wonky would pop up, and I'm guessing it was also the reason I wasn't able to pull any Earthshine out. Oh well...it was still one heck of an experience, and likely my last TSE.

All images used were taken using my trusty Canon T3i, riding on a Sky-Watcher Star Adventure 2i, using the kit 75-300mm lens at 300mm. F/11 and ISO 200. Exposures varied from 1/640 to .8 seconds, controlled by BackyardEOS. All of my longer exposures just got too blown out.

Now back to our regularly scheduled programming...

I'll call it Rev A. More cautious approach to stacking & processing than my first rev.

@kdenny2: Wow!

From Erie PA.

 

Was an interesting trip.

Got to experience an earthquake in New Jersey.

Then Niagra Falls

Then the Eclipse.

A different kind of eclipse time lapse - I've never seen it done this way before.

Really liked that.

Some great shots here!

 

I went to Dardanelle, Arkansas and had very good, though not perfect, conditions. A very thin haze and slight cloud ruined any attempt to get earthshine, and my tracking mount died shortly before totality, forcing a quick change in my approach.

Here is an HDR blend and aggressive processing of 22 sets of 7-bracketed exposures (spanning from 1/1,250 to 0.8 seconds) through my AP92 at f/5.3 with a Canon 70D.

Camera could have focused a bit better, but it's just a memory aid anyway.

Joe, I borrowed your shot.  Here’s pretty much what we saw in Carthage, New York:

 

[Susanna144]

I drove 1800 miles in my RV, visiting Sulphur Springs Texas, where we got a view of totality through a field of fast-moving small clouds.  This was taken with my Pentax KP mounted on the finder bracket of my telescope, using a 15x zoom lens.   I used the camera to make an HDR composite out of three frames, which are imperfectly aligned, with bits of cloud everywhere.  I also took a video of totality with the Canon using the telescope at about 450mm focal length.

On close inspection, I've noticed that my photo also shows the tight loops in the corona that are seen in your photo near the dark streamer coming out of the corona at 5 o'clock.  They look like the ripples a stone would cause when throne into a pond.   I thought they were post-processing artefacts in my photo, but now that I see them in other photos, they must be real.

Hi kdenny2,
Would you mind sharing your workflow, Rev A result is breathtaking. So far I got here with my images:

[swalker]

I finally completed processing all my data (I think). Turns out I did record Earthshine. Here is a version meant to be fairly natural.

AP Stowaway at f/5.3, Canon 70D at ISO 100, 154 exposures.

[ecuador]

Didn't get a lot of Solar corona detail due to clouds, but I did get a second corona (an atmospheric refraction effect) so here's my HDR of my least cloudy bracket:

 

If interested, there's more of the eclipse here.

[ecuador]

Oh, I should perhaps add a cloudy diamond ring photo which I quite like:

 

 

as I said, more details for the curious in this blog post.

Here is a one-minute time lapse/video compilation of still images from Richford, VT. 

 

https://timroske.smu...phy/i-3Jbd8k3/A

 

Partial phases captured with Lunt 50mm and ZWO178MM. Totality captured with Nikon D7500 and Nikon 200-500mm lens at f/9.

 

Eclipse Orchestrator and Sharpcap used for capture. Lots of programs used in processing, including Autostakkert 4, imPPG, PixInsight, Lightroom, Photoshop and Premiere Elements.

Indeed, results are marvellous. Although no much information about the processing flow.

Nice Images from the April 8 2024 every one. I and my buddy Mel Dawson viewed and photographed the event from  Garland TX, just east of the Dallas  area. I was impressed with  the views even though the sky was partly cloudy. I made a modified image of what it looked like to me when I looked up at it with the naked eye. It looked like a hole with the solar corona around it. From our vantage point we experienced about 3 1/2 minutes of totality.
