Hi Vars
I think the remote control idea is a good way to go if you really want to view the night skies. There are eyepieces that can be connected directly to TV's to enable you to see objects.
Meade #902 Electronic Eyepiece
You can control your ETX90 from a computer also.
Meade also have electronic focusers to suit ETX90 as far as I know.
I guess it's up to you as to what you want to do !
Good luck mate !
