As a general question and more in specific regarding the image above: Which part of the milky way, planets, stars, clusters are included in the image?

How can I know which entities are included in different pictures?

I wholeheartedly recommend astrometry.net for this sort of thing. It Just Works(tm); running on your image produced this output with absolutely no hints or guidance from me:

For avoidance of doubt, I have no association with astrometry.net.

In addition to Saturn and the stars astrometry.net circled, the frame includes several Messier objects:

  • open clusters M16, M18, M21, M23, M24, M25
  • globular clusters M22, M28
  • bright nebulae M8, M17, M20

This chart from freestarcharts.com indicates which is which.

Continuing on Philip Kendall's answer, Saturn is the bright object to the lower left of center (on the line from 14 Sgr to Kaus Borealis in the astrometry.net version of the image).
