Cut down the file real small so it could be displayed here,  this is 700 frames.

      2x barlow

It is amazing how much clearer one day is from the next.   I captured 188 more frames,   you are looking at just twenty.   That active region looks pretty gnarly, with that spiral shape to it ( on the center right about 2 inches inward )

There is so much to look at in this it is difficult to just stare in one location

Seemingly, it was a nice clear day until I looked the sky with a telescope.  Then i saw how gross it really was with a 2x barlow, i could only capture a few frames due.

No barlow @1200mm

2x barlow @ 2400mm

awesome

Looks like you were shipped a good one !  Looking forward to the results from  a clear day.  

One thing I have noticed in all my calcium experience over the last 10 years is that it almost always works best in the "worst" quality of telescopes.   Name brand doesnt mean much to a calcium filter, so stellarvue , APM and astrophysics are just bumper stickers.  In fact, a scope with the most violet fringe you see on the moon is the best choice.   Typically a generic; $100.00 meade 90mm x 800mm standard plastic cell achromat will outperform just about any $1000.00 telescope out there at this wavelength.

Have fun discovering your new skill  ,

Fascinating - had never heard of those things, thank you!  What was the time-frame over which those 200 frames were taken (I have no idea how fast these proms move!) - cheers & stay safe

this was 50 minutes of recording,  2000 frame video captures were taken at 0 second delay  intervals.   Each 2000 frame video file is 15 seconds long, and i only keep about 100 of the frames per video.

very nice

love it

Good stuff. If you ever come across any "normalising" software let me (us) know!
Just a matter of unpacking image data into an array / matrix and "dividing stuff"? 😉

I will have a look around.   It would have to be a mass file editing software because doing this one frame at a time would hurt

I know photoshop can do it automatically, but i cannot justify paying X dollars a month to use a software in what most consider "play time."   No photo is worth a monthly fee unless you are getting paid hourly  to edit them  

awesome!

as seen in calcium;  imaging conditions were the worst kind of poo today.  fighting heavy wind and heavy haze.  Glad i at least got to grab this;

Most are familiar with the continuum white light granulation,  K-grains are similar .   The image goes dark because a thick haze appeared in the sky mid session preventing any further imaging.

different process.

How on earth do you do that?! 👏🏾

I use a Skybender to tilt my calcium filters until the prominences show up

nice!

thanks guys.

Having a bit of a light leak issue on my filter housing, when i figure out how to fix that i should be able to remove that nasty glare/overcast in the center.

 200  frames.

sharpcap costs money and is limited if you do not pay.,  firecapture is free and has no limits,  you can also use it to run multiple cameras simultaneously.   

It all boils down to personal taste,    processing is sorta the same.  Everyone has their own methods,  but stacking is typically an industrial standard method.  There is just about only one proper way to do this.

Those square patterns will not go away, it is from your camera;   Several ASI brand cameras just do not work for solar imaging.

Okay, you are getting better results now. 

First and foremost,  download firecapture and ditch the asi studio program you are using.   You want your video to be recording in .SER format and nothing else.   .avi causes issues.

Secondly,  you should be using the lowest exposure time possible with moderate gain, this is how you increase your frames per second.  This is different for every camera so i cannot suggest a setting for your current setup.   What you see on the screen,  in real time is what you will see on the captured file; 

You can always fix it up a bit in imppg or photoshop,  but it is important to experiment with camera settings and firecapture is the most widely used app for imaging.

Thirdly, the stack size is the option box in the top right corner of auttostakkert with the pink boxes and all those zeros, (number of frames to stack on top)  (percentage of frames to stack on bottom)   it and it does not matter if you have .png  ;  file type here does not matter to autostakkert or imppg;   However, .tif files will be the largest storage space eaters.      

Autostakkert automatically sorts all the good frames from the bad ones,  so by Alt+clicking on the vertical line you prevent  all the worst frames from entering your stack.    Then the 8% box,   stacks only 8% of the remaining frames.     

More frames is not nesscisarily better.

In regards to the alignment box code  !#@Anchor,    this means your video lost tracking.   You can remove all the bad frames by clicking spacebar; and then in the image preview slider bar at the top of the preview window you can move to the next frame.      

Some drift is okay in the video file as long as it does not reach the edge of the image preview boarder.    In some instances;  switching crop to expand will allow the picture to accept the drift and create a larger final image but it does not always work

Shut off planet mode , turn on surface mode.  enable crop mode.     hold alt and click on the first vertical line in your quality graph,  and change stack size to 8%.

tick the "sharpened button"  then 65% blend in raw.          Change the AP size to 104, since you have little to no surface detail on your color camera you need to make the align points bigger. 

If your video is very shakey, download PIPP, and try to stabalize the video and resave it to .ser format before running it into autostakkert.   (use the prominence as your stabalization anchor)
