In my sence a good setup must offer the capability to start quickly a stargazing session with the main objective to produce (high) quality CCD photo without any hardware and material preoccupation.
To get an observatory also facilitates the easy setup with the flipping of a few switches and powered up.
For the time being, my observatory is a project. Thanks to a 3D software it's possible to do some simulations like choosing the better place to fixe the telescope on its pier or evaluating the free zone around it. This software is also suitable to study the ergonomic of the different rooms, which includes the implantation of the desk, the computers or the best place for the wiring.
