Q&A

Frequently asked questions

Can I use this telescope to look at the Sun?

No. Never use this telescope to look at the Sun. This telescope is not designed for solar observing, and no solar filter is provided or intended for use with it.

Do not use the telescope for daytime observing, as there is a risk of accidentally pointing it at or near the Sun. Looking at the Sun through a telescope can cause immediate and permanent eye damage or blindness.

Is this a finished telescope or a kit?

It is a telescope-building kit, not an assembled telescope. The campaign offers two options:

  • 3D Printing Kit – includes everything you need to build the telescope except the 3D-printed parts. Print the provided files, then assemble the telescope, and you’ll have a complete, fully working telescope.
  • Assembly Kit – includes everything you need to build the telescope. It arrives in two deliveries: the 3D Printing Kit and the 3D-printed parts. Once both have arrived, simply assemble it to have a complete, fully working telescope.

Do I need a 3D printer if I buy the kit?

Only if you choose the 3D Printing Kit. The Assembly Kit already includes all the 3D-printed parts, so no 3D printer is required.

What 3D printer do I need for the C160?

If you choose to print the parts, use a 3D printer with a build area of at least 205 × 218mm.

It should be capable of producing accurate, straight parts. Automatic bed leveling is recommended.

The printer must also be able to reliably complete an uninterrupted print of at least eight hours.

Can I build the telescope without buying a kit?

Yes! You’ll need to source all the required parts yourself, but it is definitely possible. The files and documentation are there to help you build your own.

If you manage to build one without a kit, send me an email — I’d love to show it off on my channel :)

How hard is the build?

The telescope is designed to be straightforward to assemble. If you’re comfortable following step-by-step instructions and using basic hand tools, you should have no trouble building it. The online assembly guide walks you through each subassembly with clear photos, and a YouTube video playlist is also available to guide you through the build.

How long does it take to build?

Assembly should take around 2–3 hours, depending on your experience and pace.

What tools do I need?

You’ll need scissors, a ruler, and a clean, soft work surface. A 3mm hex key is included in the kit.

Why a spherical mirror?

At this focal length, a spherical primary delivers very sharp views. That has been tested extensively. It also keeps the telescope affordable to build, without giving up a great observing experience.
