Hi all,

 

Wanted to share my H-alpha timelapse, taken with my Lunt-40, from Arlington, Texas. Hope you like it.

I used the Skywatcher SolarQuest mount. Aligning the images was quite challenging. I used Imppg multiple times....1) first to align the pre-totality images 2) then to align the post-totality images in reverse order (i.e full sun first and then the crescent sun just after totality) and 3) re-aligning the post-totality images using one of the pre-totality images as a reference starting point. I had to try multiple times, via trial and error. Due to the changing shape of the sun..imppg was getting a bit confused and not quite aligning things as it normally would. Then I used Davinci Resolve to de-rotate the field rotation (as the mount is alt-az so the subs have field rotation)

I wish I had check H-Alpha images before the eclipse so I could have been ready for that large triangular prominence.

 

On the other hand, it was really cool to 'discover' it as it slowly emerged.
