thank you for your advice, I really appreciate your recommendations. I have to say that in this moment I am really unable to take any decision. I got too many good advices from the people here!
My sky is a rural-suburban area, maybe between bortle 3 and 4. So there are better places for sure.
Let me add that identifying a scope suitable for binos is not an easy task, also because usually the critical parameters involved (backfocus, drawtube aperture) are not diclosed by the vendors.
If you can see the Milky Way with the naked eye, the achromat will work quite well. This will be when such a scope is at its best.
