I was at Palm Cove for the eclipse with my wife and two sons and we were incredibly luck that the clouds cleared just before totality. It was an incredibly moving event particularly with the clouds "just" clearing, I was still shaking for some time after totality.
My camera was busy collecting a series of exposure with the intent to stack then to reveal the extent of the corona. See attached image. This image is a stack of ten images each varying in exposure by one stop.
Software used was Fitswork as suggest by Phil from a suggestion by Geoff Sims. And of course, Photoshop.
WOW - you've nailed it! I'm glad that technique worked for you, this is an outstanding image.
I am wondering what happened to the Earthshine portion of it though? There is obvious structure visible, but the details are not there. I wonder if that could have been because of all the processing steps. Is it possible to use one of your longer exposures, stretch the hell out of it to see Earthshine, and stack it on top?

Edit: I actually cannot stop staring at this image. It is probably the best representation (of what I remember seeing with the naked eye) that I have come across so far.
Thanks Laurie, Rick, David, Paul, Mike, Geoff and Stephen for your kind words and glad you liked the image.
Geoff,
My plan was to capture earthshine and I practiced just after the last new moon on the earthshine beside the thin crescent moon sorting out what exposure was needed and applied this to the eclipse but for some reason I did not capture it. I took some of my longer exposures and stretch the hell out of them and all I got was something like what is in my image :-( In the end I just took the moon part of my image stack and stretched the hell out of it and then blended it on top of the corona to generate what you see in my image. Where I was at Palm Cove there was quite a lot of thin wispy cloud that may have hidden the earthshine from me, I still don't really understand why I cannot see it in my images.
Using the suggested Larsen-Sekanina filter, Fitsworks seems to do a great job selecting the radial nature of the corona and in some ways filters out the cloud. When you apply the Larsen-Sekanina filter you specify the centre of the sun so it knows the orientation of the radial features.
I see David (h0ughy) has captured the earthshine very well, I'll have to ask him what he did. He seems to have a *lot* of data in his image
Note that I followed the tutorial at your link using the "combine images with manual offset" option to stack my images. In addition I applied some wavelet filtering/sharpening to the mask before multiplying with the image stack.
BTW Nice time lapse Geoff, it is great to see the shadow and you can see the camera working away!
Wow that looks absolutely stunning, breathtaking corona details there! I can only imagine the quality of images that'll come out once all you guys finish processing your data.
Excellent job, Mark! My wife and I made it down to Cairns from the US specifically for the eclipse (under the guise of a vacation). We were positioned along the highway just south of Rex Lookout. We saw totality for literally 3-5 seconds between the clouds. Unfortunately, I was still focused for the solar filter, so it was out of focus when the clouds broke and I removed the filter now that it was in totality. Ugh. But witnessing it was absolutely amazing.
Not sure how you'd feel about this, but I run a free-to-schools science magazine that generally includes a classroom wall poster. This image would be perfect for one of our posters if you'd be OK with us using it? No problem if not, just thought I'd ask
I'm not on ice in space as often as I'd like, but can be contacted at timwetherell@gmail.com if you're interested
And a very well deserve IOTW it is too. It's a stunner.
