The Dynamic Eclipse Broadcast (DEB) Initiative team developed projects for the 2023 annular and 2024 total solar eclipses, building on the group's success from the 2017 Citizen CATE Experiment. The DEB Initiative instrument captured the inner white-light corona at a roughly 5 second cadence and had slight overlap with the SOHO LASCO field-of-view. The DEB Initiative data imaged the inner 90 arcsec of the corona which is not visible with the new Proba-3 ASPIICS instrument. During the 08 Apr 2024 total solar eclipse, DEB citizen science teams operated 80 telescopes at sites both inside and outside the path of totality. Within the path of totality, more than 30 teams collected approximately 500 Gbytes of imagery at locations from Mazatlan, Mexico, to Moncton, Canada. Team positioning provided over 90 minutes in coverage from the first image to the last image, but cloudy weather, combined with geographical spacing, resulted in gaps with no data during about 37 minutes of that time. We discuss the image processing from single exposures to spatially-filtered HDR summed frames using several of the types of analysis produced by Druckmuller and co-workers with some changes for our particular instruments.  We also discuss spatial and intensity calibration among several of the telescopes which collected scientific data.
