Over the last few months, CADSAS has been contributing to this Citizen Science project on variable stars.
We capture images of specific night sky objects, process those images using dark and flat frames and then send them to the project leader Dr Dirk Froebrich of the University of Kent.
The project is studying newly-formed, blue stars. Our target winter objects are currently NGC 2244, NGC2264 and NGC1333. We have submitted 8 images so far.
CADSAS are one of a small number of amateur contributers to this project.
