My Corona
20

I just processed a composite of 5 images from the eclipse, using a Nikon D810A, Nikkor 80-400mm f/4-5.6 lens, mounted on the back of a Meade 10" LX200 and APMach1GTO. I used Backyard Nikon to automate the captures, taking 30 images during the 2 minutes, 15 seconds of totality, pus an extra 20 seconds on each end. The exposures were 1/500, 1/125, 1/30, 1/8, and 1/4 sec, at f/8, ISO 200. I can't believe the details I captured in the corona. Taken from Paducah, Kentucky, under a very clear sky.

Thanks for looking.

Very nice.  I agree, the best corona detail image I have seen posted here so far.

Well done.

Best I've seen on this forum so far. You can compare yours to what the Predictive Science, Inc predicted it would look like. http://www.predsci.com/corona/aug2017eclipse/home.php

Superb work. This is the closest I've seen thus far to what I actually saw with my eyes and binoculars in nearby Tennessee.  Incredible silky-thread detail.

That's a ripper Keith. You kicked a goal there.

Re: My Corona

Great final product. Please describe your software process. Doesn't need an extremely detailed explanation. Aligning + masking in PS? Automated HDR program?

Re: My Corona

Very nice.  How did you process your sequence? I have tried various HDR programs, as well as luminosity masks and still am not satisfied with my results.

Re: My Corona

Very nice Keith!  I have photos that are very similar - one from a stack of six images.  I posted them in the Canon 7D forum and it went over like a wet dishrag.  I should have come here first.  I will post in a separate thread.
