Not accurate to an original Observatory since they open sideway, you can flip the sphere to reveal the scope and turn the head with the gear arm.
The scope need to be pulled out to extend.
I will admit it doesn’t look like a architecture at first glance and look like a deformed Darlek, but I hope you understand what it’s suppose to represent.
It’s not LDD - they don’t have the Mahri armor available as a part on that program. It’s most likely Stud.io by Bricklink. You can get it here: Studio Download [BrickLink]
@Square Could you fix the font size in the descriptions? It’s tiny!
(Edited for Stud.io referring and concerns over font size.)
