C8 with Moonlite focuser, Perfect Star focus controler, mounted on a EQ8, guided with QHY5l on a William Optics 71, and a QHY8Pro imager using a CLS filter. The whole thing is controled by a x86 mini computer running Ubuntu mate under the USB hub. Everything runs off of 12vdc. Roll off roof.... Weakest link in the chain is me.

In the pictures posted, I had not installed the ventilation. It is now in the bottom corner where the dust pan is.
I have a solar fan at the top (sucks out the air), and with the bottom corner drilled and protected by a vent grill outside and fine mesh inside, the air flow is sufficient to keep moisture out of the box. So far, no issues what-so-ever with condensation within the box, it has been out there since 23 Aug 2014 (only go the telescope in the box a month ago....) and has been dry since (minus one incident).
There was last year a nasty storm and due to a flaw in my lid design some water managed to get in. At this point, no mount or electronic was installed.
I wanted to have the box out there for 1 year at least to make sure it was good. A quick re-think and re-build of the lid solved that rain issue.
The key to fight condensation is a good air flow, do not try to get your observatory all air tight. You must have an air flow.

@ Gonzothegreat: very nice built! Would it be possible to show a bit more inside the box? How did you fix your mount to the ground? In the distant future I really would like to build a box simmilar to yours because my mount is also outside but just covered with a plastic tarpaulin.
