Photographs of galaxies far far away rarely convey just how large what you're looking at really is — after all, how can you even fathom something that is measured in light years across. But these photos of the cosmos do an even worse job. By applying the tilt-shift effect in post, these photos show galaxies and nebulae look like they could fit comfortably in the palm of your hand.
Credit for the idea belongs to Imgur user ScienceLlama, who took photographs from ESA, NASA and the Hubble Heritage Team and altered them by applying a tilt-shift effect in post. By narrowing the depth of field, ScienceLlama makes you feel like you're staring at a little puff of pink smoke when, in reality, what you see is a nebula that is multiple light years across.

Trying to figure out what Tilt-Shift Photography is, that web site doesn't explain it.

This does:

Tilt–shift photography is the use of camera movements on small- and medium-format cameras, and sometimes specifically refers to the use of tilt for selective focus, often for simulating a miniature scene. Sometimes the term is used when the shallow depth of field is simulated with digital post-processing; the name may derive from the tilt–shift lens normally required when the effect is produced optically.

"Tilt–shift" encompasses two different types of movements: rotation of the lens plane relative to the image plane, called tilt, and movement of the lens parallel to the image plane, called shift. Tilt is used to control the orientation of the plane of focus (PoF), and hence the part of an image that appears sharp; it makes use of the Scheimpflug principle. Shift is used to adjust the position of the subject in the image area without moving the camera back; this is often helpful in avoiding the convergence of parallel lines, as when photographing tall buildings.

Scheimpflug Principle:

The Scheimpflug principle is a geometric rule that describes the orientation of the plane of focus of an optical system (such as a camera) when the lens plane is not parallel to the image plane. It is commonly applied to the use of camera movements on a view camera. It is also the principle used in corneal pachymetry, the mapping of corneal topography, done prior to refractive eye surgery such as LASIK, and used for early detection of keratoconus. The principle is named after Austrian army Captain Theodor Scheimpflug, who used it in devising a systematic method and apparatus for correcting perspective distortion in aerial photographs.

Ah! It's all clear now

I'm gonna get them up on my wall, they are beautiful.
