Secondary Mirror
Why does the camera take pictres that look different?
When I take with the secondary camera on my Nokia phone camera it looks like wayyyyyyyyyyyyyyyyy different... If I use the regular camera that I am more use to seeing what I look like on. The mirror pictures I take also look quite different.
Your regular camera was designed to be a camera and does its job very well.
Your phone is NOT a camera, but a really good phone with a camera feature that uses a tiny sensor and in many cases, nothing but a pinhole lens.

Hubble's View Of The Universe [Part 10]
What is the Shape of the Primary and secondary mirror of the Hubble?
Hubble uses a Ritchey-Chretien Cassegrain optical system, with a hyperbolic primary and a hyperbolic secondary.
The primary is slightly defective, resulting in spherical aberration. All instruments on board now incorporate corrective optics to compensate for this.
