WebThe role of amateurs and small-scale equipment in astronomical photometry is reviewed. The value of suitably selected projects for both research and educational purposes is stressed. Recent technical developments are noted, and a brief extrapolation to possible future arrangements included. WebAccurate measurement of magnitudes, however, was only made possible in the 20th century through the advent of photoelectric devices. Stellar photometry is that branch of astronomy that deals with the accurate measurement of the brightness of stars and the changes in their brightness over time. It probably had its beginnings in the 18th Century ...
WebPhotoelectric photometry (Henden and Kaitchuck 1990) provides precise measurements of variable stars that can be recorded and then reduced to accurate magnitudes. Using different filters, color indices can also be measured yielding additional information of astrophysical significance.
