The image is a mosaic made of 16 smaller fields of view, which, once stitched together form a high-resolution image of 204 Million of pixels! As of matter of fact, this is not the work of a single person but by a team of five french amateur astronomers called "Ciel Austral"
Ciel Austral" owns a remotely-controlled observatory located in the most prestigious skies of the planet, in Chile, and more precisely at the El Sauce Observatory (Coquimbo Region). A 160-mm APO-refractor telescope and a Moravian CCD were used to obtain this wonderful field. The datasets were taken over several months, ranging from 2018 and 2019. The heavy files handled represent 620 GB and needed few hundreds of hours to get out of the image processing step! Once stacked together, they make up the stunning figure of 1060 hours of exposure.
astrophotographers used a couple of special filters which transmit narrow parts -lines- of the visible spectrum : the Hydrogen Alpha line at 656 nm, the Sulfur line at 672 nm and the Oxygen III spectral line at 500 nm. These kind of filters enable to emphasize chemical components located in high-density gas regions like nebulae, what standard RGB imaging can not perform.

With luck someday humanity will explore those places.
Impossibility begs to differ.

I wonder if you could attach another telescope to the telescope above and zoom in even further.
The science team that developed the new Advanced Camera for Surveys be installed in SM3B points out that the high resolution channel of the ACS should resolve two fireflies separated by about 10 feet at a distance corresponding to the distance between New York and Tokyo..
