Zero-loss energy-filtered 3D electron diffraction experiments are performed using a post-column energy filter, and both data quality and structures are improved after energy filtration. A novel crystal tracking method is developed, based on a live high-angle annular dark-field image stream. This method can track crystals to achieve high-completeness data sets without adding any additional dose or removing any frames.
