Today was another mostly cloudy day, but there were breaks in the cloud cover. During those breaks, I made a number of AVI movies of the sun – ranging from 400-1300 frames in duration. I took the best 20% of the frames from the longest AVI and stacked them to create this image of the solar disk.
The bright plage that was at 10 o’clock yesterday has moved toward the interior of the solar disk revealing the sun’s rotation. The solar prominences from yesterday are gone, and new ones have taken their places. Below are cropped images of the prominences at the left solar limb and from the top of the disk image.
My photo workflow is as follows:
- Stack the best 20% of frames from the AVI using ASIVideoStack and save as a .jpg
- Adjust the curves and levels of the image in Canon Digital Photo Professional 4
- Apply Topaz DeNoise AI to optimize the image’s quality
- Use the Windows JPG editor to crop the final image as needed
Today, I remembered to take a picture of the solar rig mounted on a lighter mount than I used the first time. It is much easier to move out onto the deck and then return to the living room.
