All you need is a large-ish telescope 🔭, in this case the 3.6m Canada-France-Hawaii-Telescope on Maunakea, Hawai'i 🌋. 26 images of each 3min integration were combined into this video. Euclid had a distance of 920,000 km from Earth!
Here the very wide-field MegaCam on the CFHT #telescope was used, a camera 📷 that in its design was a precursor to #VIS, the wide-field visible wavelength instrument now onboard #ESAEuclid. How wide field? Well, the full area covered by MegaCam is about 80 times larger than the area shown in the video.
