Taken with the 100mm at 2000mm focal length, this is a stack of only 10 frames from autostakkert2. The image is slightly noisy as a result, but does show a wealth of small scale fine details. I do wonder that by stacking with image stacks up in the 100s of frames if some of the details are just being smeared out by seeing variations or through temporal distortion. Either way, the use of smaller stacks at these shorter wavelengths is something I will be exploring in more detail when the sun returns again.
