Live Stacking for solar timelapses
Posted: Wed Jun 30, 2021 4:49 pm
OK, here me out
I'm really into full disk solar animations, and this would probably only work for this. But it would automate things, and save a lot of time!
Currently, I use Sequencer to take 500 frames every 30 seconds. Works like a charm! BUT it takes up A LOT of space if you image for hours and hours. Not to mention the time it takes to stack all these movies in AutoStakkert!!!
So what I'm thinking is this; what if we could use SharpCap's Live Stacking option in combination with Capture Limit?
You would set up Capture limit to run Live Stack every 30 seconds. Live stack would then take the number of frames you have selected (lets say 20), and save those as a stacked image. You will then use these stacked images in your animation, avoiding the AutoStakkert step.
Sure, you won't be able to align these frames as you take them. But with todays high speed cameras, just stacking them should be fine. At 100+ FPS, taking 20 frames will take no time at all, freezing the seeing.
Also, the short focal length we use for full disk imaging, is more forgiving when it comes to turbulence/seeing.
What do you think? Doable?
Thanks!
