WebApr 4, 2024 · WASHINGTON — Researchers have developed a new way to produce and shape large, high-quality mirrors that are much thinner than the primary mirrors previously used for telescopes deployed in space. The resulting mirrors are flexible enough to be rolled up and stored compactly inside a launch vehicle. “Launching and deploying space … WebMay 27, 2024 · There was a thread on the PI forum where somebody asked or a solution to eliminate spike artefacts on a alt-az telescope. (the spikes rotate in respect to the background because of the field rotator and that is virtually impossible to correct in post). Not sure if it is appreciated if I post the link here. Therefore a short summary.
