We absolutely use short exposures. It's actually more important for us than the pros because the mounts are a lot less stable and polar assignment is far worse.

We absolutely use short exposures. It's actually more important for us than the pros because the mounts are a lot less stable and polar assignment is far worse. Doing a lot of short exposures is a lot easier than nailing your polar assignment. It also help with bad seeing; you throw away the blurriest quarter of your images and the stack looks a lot better. Filtering is less advanced, but masking outliers (and their neighbors) and replacing them with an average of the others isn't advanced filtering. It's annoying the way getting cut off in traffic is annoying, not the way getting T-boned is annoying.
