Description
Observers most commonly use imagers to gather Johnson/Cousins photometry, but cameras have a difficult time with stars as bright as alpha Orionis. Superior results are obtainable with single-channel photometers in the old-school technique known as PEP. We review such data in UBVRIJH from 2019-2020.
