Well, yes I can acknowledge that dew is less of a problem than being outside, and as I am a ROR owner, that statement applies to ROR obs as well; however it may be impacted by how much you need to roll back the roof. My pier is located towards the Southern end of my obs, and with a partial open roof I can image fine and still have my workstation area under cover.
As far as screen light control goes, I use Backyard Red, which is a free application that gives your screen a red cast and is variable in intensity. I run Backyard Red, and turn the brightness slider down to dim. I also use a dark towel that I can work under, aka the old shroud that old time camera operators used to use to prevent stray light from entering images when they changed film plates. Once I have everything set up and running, I usually drape the towel over the screen and retire to the house, where I run Teamviewer on a small laptop to monitor and control the main laptop systems in the Obs. I run SGP as my imaging app, and it remotes well under Teamviewer. Teamviewer is setup so that only local LAN connections are permitted, and it uses my WiFi network.
