from the direction of the shadows, and the orientation of the telescope's polar axis, the solar illumination appears to be from the north east. Unless this observatory is located in the southern hemisphere, where the polar axis is aligned with the south pole, this is clearly impossible.

I know its a nit-picky detail, but when you choose a telescope as your subject, astronomers will be especially vigilant for errors of this sort and intolerant of them. If this image were to be used in advertising for a dome kit, the customers would start with a negative opinion of the product and a loss of confidence in the manufacturer.

Equatorialy-mounted telescopes are usually shown in this orientation in their marketing literature because they look better, they appear more balanced and symmetrical when aimed right at the pole (just like advertising for timepieces often shows them set for 8:20). But it is a very awkward and difficult configuration for any scope to operate in, as anyone who has tried to observe objects near the poles can testify. Unless the scope mounting has a clock drive and a go-to feature or properly aligned setting circles, it is difficult for an observer to manually orient himself and almost impossible to locate and track objects near the poles
