Observing the Sun with Coronado™ Telescopes
At around the turn of the millennium, the introduction of the Coronado range of solar telescopes and filters heralded the ‘coming of age’ of amateur solar astronomy. Before then, solar astronomy was mostly white-light only. Hydrogen-alpha systems were expensive and difficult to use, but today even the budget-priced Coronado PST (Personal Solar Telescope) provides a band pass of one Angstrom and is thermally stable. That means that today’s amateur solar observers can see – and image – sunspots, flares, prominences, plage, filaments, and active regions of the Sun, all in amazing detail.

Museum Digitisations and Emerging Curatorial Agencies Online : Vikings in the Digital Age
This book explores the multiple forms of curatorial agencies that develop when museum collection digitisations, narratives and new research findings circulate online.

Furthermore, it considers eco-systemic processes comprising computation, rare-earth minerals, electrical currents and data centres and cables as novel forms of curatorial actions.
