When astronomers dream of their ideal telescopes, it’s not that different to what people want from their TVs and computer monitors. Images they produce should be large and high definition, such as those from the Australian Square Kilometre Array Pathfinder (ASKAP), which have ~10k resolution (beyond the typical quality you get from digital TVs and digital cinematography). And they should have a high dynamic range, indicating high quality imaging with deep sensitivity to faint objects.
But not every telescope can do it all. That’s why complementary science – using some telescopes for some tasks, others for different but related tasks, and then combining the data – is so important in astronomy.
