But getting a dramatic image from a stack created by a script is something I would use and add to my folder of "shots I like".
I think I agree with you.
From that perspective, we could think of yass4 as a tool to provide what I would call "natural bracketing": you rely on Nature - specifically, on Earth's rotation - to give you the variety of exposures you'd otherwise had to artificially produce by changing the camera's exposure at a given moment.
In this sense, what yass4 does is just to follow what is given outside the camera, that is, a natural change in luminosity, as opposed to the artificial exposure change in standard, instant bracketing.
Interesting to think about it this way, I guess.
Changing subject, maybe it would be interesting that you guys create a sub-forum for people to share their work, maybe creating, from time to time, some kind of contest. I saw something like that on an astrophotography forum and the share-your-work sub-forum seemed very active. I'm sure that after creating it, a simple call in your Facebook page would atract many people. Since it wouldn't be a Q&A sub-forum, it wouldn't give you admins much work I guess.
