Bright Star Monitor Stations
The Bright Star Monitor stations are a subset of the AAVSOnet. They offer members an opportunity to do CCD multi-filter observing of stars from 2.0 to 13.6 in Vmag with robotically controlled telescopes that are located from New Hampshire to Australia. Images are automatically calibrated and are provided to the user for analysis. They can also be directly forwarded to a VPHOT account.
