20: Follow up with information about coronagraphs

After reading in a forum about Peter's Sirius B project I find it interesting to collect more information about coronagraphs.

This will just be a collection of links for you who are interested to get a bit deeper into it.

Useful links with theory and technical function:

• https://en.wikipedia.org/ wiki/ Coronagraph (Coronagraph, Wiki)
• https://jwst-docs.stsci.edu/ display/ JTI/ MIRI Coronagraph Masks (JWST)
• http://lyot.org/ background/ coronagraphy.html (Background Coronagraphy, Lyot.org)
• https://www.princeton.edu/ ~hcil/ papers/ rvdb_SPIE_Shaped_2004.pdf (Shaped Pupil Coronagraph, Princeton)
• https://pythonhosted.org/poppy/coronagraphs.html (Efficient Lyot coronagraph propagation, Pythonhosted.org)
• https://www.nasa.gov/feature/jpl/new planet imager delivers first science (Vortex coronagraph, Nasa)

I also found an amateur coronagraph project:

It's in French so you have to translate it maybe.
