This is a telscope that I did for the office scene that I am working on. I won't be able to upload it here as it is far to big to do that but I am posting some of the things that I am using in the scene. The entire thing is parented and the tripod legs are locked to rotational constraints so that they can be rotated by 20 degress from opened to closed. The same applies for the entire telescope, the pivot of the scope rotates from 60 to 135 degress and is also locked to its position. It's a functional model. Textures are from plaintextures.com and the environment image is from HDRIhub.com, a free sample.
