When you receive your package and open it up, you will see a cylindrical black foam with a red tape placed in between the mirror mount of your Unistellar telescope and the onboard computer. The foam is here to protect the telescope and prevent any damages or shocks that could occur during shipment which is why we made it very tough and tight.
The foam has to be removed but kept in case of return. Because of how tough (but protective) this foam is, it can be hard to remove. The easiest way to do so is by pushing it out from the back and it will slide on the side.
