A pirate is a sailor who needs a telescope to see across the great ocean! I was watching pirates of the Caribbean and I noticed Captain Barbossa had a small hand held one that extends out. I took that as reference and made our pirate one.
This was pretty easy to model. I started with a pipe polygon and and extruded the faces making it thicker at the top. I also give it a bevelled round each at the bottom. I then duplicated the shape, scaling it smaller and placing it next to the bigger shape. I repeated this until I got the look of a telescope that can expand and retract into itself, as show below:
For the UV mapping Automatic seems to work well. I tried to stitch in places but it went distorted and looked better left alone. I selected layout and normalised the squares to get them straight. There is a seam but it can easily be hidden at the bottom of the telescope.
