360º Planetarium

i stumbled upon this technique sometime around 2012 and have since then been making these 'timy planets' and 'wormholes'. though there now exist 360º cameras capable of capturing these kinds of images, in one click, i prefer to use the old method of taking around 20 pictures in a circle with my DSLR and stitching them together on the computer. though much more time comsuming the Resolution i get is insanely BIG and detailed.
