This workshop will introduce the first of the Skynet Robotic Telescope Network’s second-semester STEAM education labs from the upcoming Multi-Wavelength Universe! curriculum. In the lab, students will collect multiband images of open and globular star clusters with Skynet telescopes, then use Skynet’s web-based, open access tools to align and stack images, run calibrated photometry, and produce both colour images and cluster HR diagrams that can be used to estimate age, metallicity, distance and reddening through isochrone modelling. Workshop participants will work through the steps of this analysis, from data acquisition to image processing, source extraction and photometry, and to colour image production and multiband colour-magnitude diagram analysis and isochrone fitting.
