Elp Posted July 12, 2023 Share Posted July 12, 2023 And here's me looking for the chance to image it just for an hour or so before it disappears for another year. Do you think it'll look anything like this? Link to comment Share on other sites More sharing options...

However, maybe they do, some apparently only show up in IR. I had a look at Liverpool Telescope HaRGB data (a 2 m RC on La Palma) that I processed several years ago (https://www.astrobin.com/286659/). And, those additional star seen in the JWST image are NOT there, so clearly JWST Near-IR images reveal stars that we do not see in visible light. I am still puzzled. Cheers, Göran Dust stops light with a wavelength smaller than the dust grain size. So longer wavelengths pass through dust like it’s not there. I have been meaning to try a NIR filter on a partially transparent dust cloud like the Iris Nebula to see if it can resolve any hidden stars. 1 Link to comment Share on other sites More sharing options...
