Astrophotography by Michał Markowicz
Warren A Keller Inside Pixinsight 2nd Edition
"Inside Pixinsight" is a very good guide book describing how to use the many available functions of Pixinsight for advanced astrophotographic processing of night sky photos. I have used it many times, I recommend it.
Stephen Hawking - A Brief History of Time
The book covers a number of issues related to black holes
Steve Richards - Making Every Photon Count
The book is intended for people who want to explore the secrets of astrophotography.
David H. Devorkin & Robert W. Smith - The Hubble Cosmos
A publication in the form of an album with many photos obtained from the Hubble telescope with detailed descriptions of how the photos were taken and information about the photographed objects.
David H. Levy - Heaven user's guide
A valuable collection of basic information about the night sky. We can learn from this book how to "read" what we see in the sky and how to observe, for example, meteors, comets or planets.
