For me usually about 30 minutes or even a bit less, depends if i stuff up the process.
The set up can be fired up at a moments notice, however i let it reach ambient temp for a couple of hours before i start to do anything.
Ok, when it is dark enough, switch on the Gemini and send scope to a star of my choice, center it in the Tak finder scope, hit sync, focus on that star with eye only, i don't use any software at all, never have.
Send scope to desired object, and just let it run while i turn on the lappy, take one image at the length of time of the ones that i am going to take, check it on the lappy for focus, position, noise levels, more/less time, etc.
When happy, put mount in Photo Mode, set Canon Remote to length, amount of images, and gap, open Phd, find guide star, and callibrate, once done, press remote and walk away, well not really, but it is of and running.
