Hi Kamil
Here is my two cents. Like you, I'm fairly new to astronomy.
Like the others said join a club (at least check it out). The info you'll pick up is mind blowing, there is more to astronomy that looking in telescopes, stuff like :- Spectrograph ect. The wealth of knowledge and experience of the members is great. Some club have loan telescopes (that's how I learnt dods mount was easy, and my friend's equatorial mount frustrating).
Binos or telescope it pays to deal with an Optical shop (most of them are astronomers their advice very helpful), as apposed to a non optical (dept type) stores who sell camping equipment ect as well as optical stuff.
If you get a dobsonian you need to think :-
Collapsible or Truss type - easy to transport ect.
Solid Tube - can be mounted on an equatorial goto type mount.
For me 10" dobsonian (solid), mid next year EQ6 Pro mount (by then I would have leant enough from the club to understand it, & not get frustrated), by the end of next year astrophotography.
Hopefully I was able to help you.
