Is this image an original picture which is not photoshoped? I see a huge number of Hubble Telescope images on Google and I'm curious whether they are real images or not. If not, where I can find the real images captured by the Telescope which are not photoshopped?
$\begingroup$ Can you provide a link to where you found the image? $\endgroup$– HDE 226868 ♦Jul 4, 2017 at 18:14
1$\begingroup$ I just googled "Hubble Telescope images" and it's one of them. $\endgroup$– lemoninciderJul 4, 2017 at 18:31
1$\begingroup$ With reference to the comment above, this image is titled Hubble Ultra Deep Field 2014 and can be found on the following official sources: hubblesite.org/image/3380/news_release/2014-27 and apod.nasa.gov/apod/ap140605.html $\endgroup$– Dhruv SaxenaJul 4, 2017 at 18:51
2$\begingroup$ Well, all images are post-processed, or reduced as it is called, to some extent. For a start, color images are combined from three different images taken with different filters in three different wavelength bands (e.g. RGB). Also, a deep exposure like the HUDF is combined from a large number of short exposures. $\endgroup$– pelaJul 4, 2017 at 20:04
1$\begingroup$ @lemonincider one way to think of it is that modern telescopes simply don't make "natural color" images (like a camera). You're probably familiar with an infrared camera or indeed just an Xray machine at the doctor's. Those don't make "real" images in any meaningful way - right? There simply is no "real" image of an infrared image. (If you as a human look at an "infrared scene" you simply see - nothing). Similarly modern telescopes, in short, simply don't at all make natural "human light" pictures. You can google Hubble "natural color" images (which the scientists make to look that way!) $\endgroup$– FattieJul 8, 2017 at 18:48
All images provided from large telescopes are a rendering of the data for viewing pleasure. Usually sensors are sensitive in a wide range of wave length, even outside what humans can perceive and color is added by using filters. Hubble uses infrared filters and the so-called Hubble palette (false color).
So, if you mean, do these pictures show what a human observer will see? No, they don't. They are a visualisation of the data collected.
All things observed at low light conditions are black and white, as humans lose color vision at low light.
