| Feb 12, 2022 at 5:05 | comment | added | uhoh | For example all the bright stars in Hubble images have four points due to the four vanes supporting the secondary: Does this telescope only have a 4 blade aperture? and Why not use only one support vane for the secondary mirror, to avoid multiple diffraction spikes? and What is the cause of all of these sharp, concentric rings around bright stars in this HST image? | |

| Feb 11, 2022 at 22:46 | comment | added | Organic Marble | What is the relevance of this to space exploration? Are you asking about telescopes in satellites? If you are asking about ground scopes, ask at the astronomy stack. | |
