Refractors vs Reflectors, focal ratio and magnification

Hello IIS members,

My first search was for a forum, and it took me here earlier this week. I have already learnt quite a bit thanks to this site. My first post and I'd like to say a great forum with a great community. Well done!!!
I have never looked through a telescope before. I have my 15 x 70 binoculars on their way from Andrew's. All thanks to the research done here.

My questions-

To what degree are reflectors more suited to DSO's and refractors suited to planet/moon observation?

How does the focal ratio and magnification affect what is viewed when comparing the two scopes in respect to DSO's and the planets?

Is a high focal ratio simply inferior to a low focal ratio? Or does a high focal ratio allow for sharper images at higher magnification compared to a low focal ratio?

I know I should look through a scope to help my understanding and I will, perhaps visit the pony club?... when I understand the sky a little more so I'm not too overwhelmed.


Last questions- how heavy is an 8" and 10" dob and does the OTA detach from the mount? I'm wondering how a dob is transported, back seat/boot/trailer?

So, until I have a chance to see for myself, I await your answers.

Pat.
