ghoulish prominence

Some nice prominences from a sunny weekend:

Prominence 
10/12/25
22:08 UTC

anyone see a ghoul dancing on the sun?
or maybe kokopelli (wikipedia)


animation from the day before (worse seeing):

Solar Prominence 
30 minute animation
10/11/2025 
19:37 to 19:57 UTC

Imaging details:

Here's the lunt on a tracking mount:





Lunt 60 PT B1200 single stacked
zwo ASI 290MM
20 second captures
best 75%
animation
10/11/25
unguided solar tracking on celestron CGX
single frame
10/12/25
manual guiding with alt-azm mount
East Bluff, CA

as you can see, the "seeing" wasn't great during the animation with frames seeming to go in and out of focus.  
took a stupid amount of time to process the 59 frame continuous animation.  
should have put a delay between frames.  
the seeing and prominence shape was better the second day, but didn't have the time for an animation

maybe a little oversharpened on the single frame ;)
