The model IQ is the smallest car made by Toyota in 2015 and has significant cubic space available when the rear seats are in the down position. At this location, a high powered and dense array of science equipment is stowed. When the hatchback is unlocked, the telescope is unveiled and the mobile observatory appears.
The mobile observatory is driven to a dark country location where temporary observing will be optimal. As this is a full celestial observatory, access to power and accessories are available. The IQ can also carry blankets, provide napping or sleeping for two, and stow food.

It's possible to extend functions with a tiny two wheel trailer which opens up into a camper with equipment, cooking stove, porta potty, housing tent, and additional amenities of home.
Photos: The Smart car, with about the same horsepower engine is capable of pulling the illustrated trailer. The example shows that a more powerful Scion IQ car can also pull a trailer. In another example design, the trailer itself can become the observatory, housing the telescope and equipment. The snap off roof can be a waterproof canvas material for the ultimate in light weight portability.
