Eclipse from Cacalotan/Mexico : first results / motion in the corona
Hi,
Here are some first results of the processing of the TSE images see from Cacalotan/Mexico (south of Mazatlan).
The sky was covered with cirrus of various density during totality. Still, conditions seems to have been a bit better than at Mazatlan (which was our originally planned spot).
I could make use of about 20 s of clearing for this first HDR composite. The objective at this stage was not to have a pretty picture (more work is needed for this ...), but to identify coronal structure and motions in the corona.
Here is the HDR composite at 50% resolution :
http://astrosurf.com/viladrich/astro/ec ... 4000px.jpg
Stars are visible up to mag 11.
More interesting are the motions detected in the corona :
Here at 50 % resolution :
http://astrosurf.com/viladrich/astro/ec ... m-50px.gif
and 100% resolution :
http://astrosurf.com/viladrich/astro/ec ... R25-10.gif
- Expansion of streamers can be seen at 11h, 9 h and 5 h directions,
- Dark "voids" going downward (i.e. to the Sun) are seen at 1h and 5 h directions,
- A small expanding bubble is seen near the 9 h direction.
It is better to display the GIF at 50% to 100% zoom to identify these motions.
Stars are seen to move too. This is because of the relative motion between the Sun and the stars (images are registered to the Sun).
Too bad only 90 images could be actually used out of the 500 taken during totality :-(
The instrument was a ZWO FF 80/600 refractor with a Nikon Z7 II on an iOptron HAE29EC mount.
More to come (but much latter ...) with a complete version including prominences.

Hi,
Here is a much improved version including the inner corona and proms :
http://astrosurf.com/viladrich/astro/ec ... e2024.html
Still a lot of work to be done.

Thanks Alexandra !
This is still an ongoing project. More work is yet to be done.

Re: Eclipse from Cacalotan/Mexico : first results / motion in the corona
Very interesting Christian
The final results will be more than impressive I'm sure
I think you mad ea good choice on your location...I was in Mazatlan and the cloud was thick enough to ruin attempts ate the fainter corona details.

Thanks Brian and Mark !
I working on a near final version. I'll post it next week.
Moving south of Mazatlan was a bit of a gamble. Too bad you were clouded at Mazatlan Brian.

Re: Eclipse from Cacalotan/Mexico : first results / motion in the corona
Hi all,
Here is a much improved version of the image of the eclipse.
In fact, there are two version ...the first with a lot of contrast to detect the maximum of structures in the solar corona :
http://astrosurf.com/viladrich/astro/ec ... ne2024.jpg
The second version has a more "usual" look :
http://astrosurf.com/viladrich/astro/ec ... ne2024.jpg
Full-resolution images and processing information are presented here :
http://astrosurf.com/viladrich/astro/ec ... e2024.html
Clear skies !

Hi Christian...
You updated image look fabulous
The structure you have recorded and processed is amazing.
Brian
BTW, we had a good view of the eclipse but the thin cloud limited our ability to capture the outer corona.

It is also good news you could have a view at the corona, even if the fainter extensions could not been seen.
