Sorry but you do not understand the instruments used to obtain those images, which are nothing like your eyes or a regular camera, which can not see IR or UV and can not detect the plane-wave fronts, the simple lens of your eyes just can not do it. You need to accept that humans in space will always have to use instruments in order to be able to see what's out there.
Yes and once again I suggest YOU recheck what YOU assume about what these cameras see with regards to IR & UV.
When you make an assumption and someone posts an image that contradicts your claim you move the goal posts and you keep doing that.
These instruments are almost like your eyes remember your eye is a detector its your brain that assembles the picture!!!
The lens of your eye projects an image on the retina to its light sensitive cells, they react produce a signal that goes along the optic nerve were the picture is assembled by your brain.
A digital camera lens projects the image onto the sensor (ccd or cmos) that is turned into a signal which is converted and processed by the cameras processing chip (brain) and the image stored in the memory.
Modern digital cameras have an IR filter on them you get special models like the Canon 60Da
Canon 60 Da
This camera has the IR filter removed for astrophotographers and as you can see from the top 2 images on the link produces better images of nebula & galaxies.
It will produce strange colours if used for normal images unless a filter is used and you also have problems with auto focus.
The images from shuttle/ISS are from a normal Nikon DSLR , also like I said in a previous post you kept going on about no images of stars/clusters/moon taken from the shuttle/ISS yet when links were posted you claimed to have posted the images yourself on other threads care to explain that
