Solar Time Lapse - 2020-05-06

[PhotoGav]

Here is a time lapse of the beautiful prominences on the off going limb yesterday. It shows 64 minutes in 6.2 seconds. I captured two 8 second videos, one for the limb and one for the disk, about every minute for the duration. Kit used: Lunt LS50T Ha with Chameleon3 and a 2.5x PowerMate. Processed with AS!3, ImPPG and hours in Photoshop to make the animation! Depsite the poor seeing and subsequent wobble, I think this is my best effort yet at a time lapse. It's one heck of a hassle having to combine two images for each frame though - what's the shortcut to achieve this kind of timelapse with just one shot per frame?

Great capture. I watched a short video of (I think) a close up of  the same event on Space Weather. 
 

The plasma falling back to the surface is a sight to behold.

Holy F!

Fantastic time lapse well worth all the effort involved

Nice animation, Gav! (Indeed - animators have my respect!) 🙂

When I have done animations (a while back, so my memory fades! lol) I used
the "autorun" facility in FireCapture in a 1:4 min on-off (imaging) "duty cycle"?
I processed ALL the resultant .avi's separately through AS!3 (A bit tedious)! 🥳

I then loaded the resultant images into GIMP layers and hand aligned 'em! 🙀
Not as terrible as it seems, if you have a "system"? Basically I take images in
pairs, sequentially, and then set GIMP to "subtract" the two? I then use the
*arrow keys* to move the "top" layer (pixel at a time!) for "max blackness"?

Aside: I was quite successful with Prominences. Less so with (part) "Disks"...
With the typical thin clouds / contrails to passing by, the brightness varies!
So NOW might be a *better* time to try?!?! An unexpected challenge was
unexpected re-appearance of (faint) Newtons Rings adding "shimmering". 😏

The above is just "waffle", but I am reminded that I might profit from the
current "social isolation" to THINK more about automations!
I also do recall ImPPG had potential in this respect... 😎

Thank you for your comments, all.

@tomato - I just looked on spaceweather archives for the time lapse, but couldn’t find it (they do have a lovely time lapse of comet SWAN on there today though!). Any ideas where it is please?

@Macavity - I use Genika Astro for capture and run a sequence on repeat. It makes that bit much easier, though I suffered from hard drive lag (despite it being an SSD) and lost quite a few videos. The tracking with the Mesu200 wasn’t too bad, but it was moving off centre a bit. Irritatingly I forgot to shoot a flats sequence and there are a few wandering spots that spoil the finished article. Nevermind! The processing is not too difficult, but it does require large quantities of patience. ImPPG is very good for the frame alignment. Get out there and give it a go. The weather is set to turn colder with northerly flows which should settle the seeing down a bit, I hope. Good luck!

Amazing, I love the speed estimate for the falling plasma at 100,000 mph!

Love seeing the movement of the plasma!

Absolutely fantastic! I love this, dream capture.
