Frequently Asked Questions

Please reach us at contact@cassi-telescope.com if you cannot find an answer to your question.

Your kit includes everything you need to start sky watching. All you need to do is assemble the telescope body, insert the mirrors and scope, set up a fine-tuning system, and attach a scope or camera.


Don't worry! Just like you, when we started working on Cassi, we knew very little about telescopes. We wanted this project to serve as your guide to the exciting world of astronomy.


Cassi includes an introduction to telescopes — a short book written by young scientists like yourself. You will learn about various types of telescopes, their operation, and the key components that play a crucial role in space imaging.


We also asked our engineers to share their fascinating stories about how they were drawn to science and decided to pursue this field as their career.


We are currently developing the Challenge Atlas, an AI-powered portal that will make space exploration even more exciting.


Lead times vary depending on the product availability. We are working to deliver the first orders by Christmas 2025.
