Calcium limb flare 7/14

[Kitsunegari 571]

 

 

this little active region put on quite a show and i captured till i ran out of drive space.

160 frames x 40ms delay.   (220 frames in each stack)  (8 seconds per video capture) (160 captures)

Animated with https://gifmaker.org/   

Cropped with avidub.  Logo applied with avidub . Levels adjusted with avidub.

Files converted with PIPP and registax 5.1

Three pass Processing done in ImPPG (.xml files attached)

127mm x 1200mm explore scientific first-light achromat with Meade 2x tele-negative barlow.  Basler aca720-520um camera. 

Baader planetarium 36mm B-BCCD filter for energy rejection 

1 angstrom calcium filter from Apollo Lasky @ http://calcium.solar

Excellent! To me it's the best thing to image on the Sun: a boiling, spiking active region  right on the limb. Good to know it can look spectacular also in CaK.

Don't forget to try the mass cropping of your frames in GIMP.

i figured out that i can use PIPP to do the mass cropping with autosaving.   I did not see an mass saving feature in Gimp  and each one needed saving individually which took a very long time.   Do you know a trick to do a batch process?  That would help me out a ton!

 

I am in love with CaK right now,  nobody else is doing these 393nm timelapses so  it makes these captures incredibly unique.     The ES127 first light achromat has proven to be a winner at this wavelength.      

 

I am very satisfied with the basler aca720-520um despite its tiny resolution,  it is invaluable with the fast capture speed  for this.

 

Today i captured at 350 frames per second, with no delay per video.  Each video capture is about 4000 frames and  I stacked 220 per frame..

Right, you cannot save the layers individually with one command. In my workflow, though, it's not needed: I "open as layers" to load all frames, crop and/or resize, check the animation using Filters/Animation/Playback..., and then export straight to an animated GIF.

Gimp .gif animated timelapses are hundreds of megabytes with the amount of frames i am using.  They are also display very bad image compression which degrades the image big time..    

 

Currently i use https://gifmaker.org/ to develop my aligned images.

This sounds like color-reduction side effects (GIF uses lossless compression, so compression artifacts like in e.g. JPG are in fact not possible). Make sure to select Image/Mode/Grayscale before exporting.

attached are the zipped raw files for anyone that wishes to process this time-lapse with  their own style.

i just learned another user (rigel123) captured this same event in hydrogen alpha,

Absolutely stunning work!! I am loving your CaK results
