Telescope question

Hi I'm new here,

I’m trying to figure out the best telescope for my requirements which will be suitable for a long time and I would value any advice you might be able to give. The moon and planets are certainly of some interest but I’m very interested in the deep sky as we live with dark skies on 40 acres at 900m altitude with a 360 degree view. I’ve been reading excessively about various characteristics of aperture, f ratios etc and have come to the conclusion that a good all-round size is the 200 x 1200mm reflector, as is often used in Dobsonian arrangements. The f 6 ratio sounds more forgiving in the optics and a good light gathering scope. Unfortunately, I’m not all that keen on the Dob mount as I can see the situation where I get it all set up for the kids to see and then the object has either moved out of view or they bump it slightly and we’re off a few million kms.

It seems that an excellent package would be a 200 x 1200mm reflector (with 2” Crayford focuser) on an EQ5 mount. No one seems to sell such specs. The longest seems to be 200 x 1000. Is the 1200mm too ungainly to work, or is it the strength of the mount that is the issue? Further to that, if the mount is the issue, is it the head or the legs? I’m more than happy to set a pier into the ground. Would the EQ5 head be adequate and can it be readily attached to a pier?

So many questions…
