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?

The Meridian C160 comes as a kit that you can assemble in under two hours into a complete, fully working telescope. We offer two options:

  • Full 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.
  • 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.

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

Only if you choose the 3D Printing Kit. The Full 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.

What filament should I use?

PLA and PETG-CF have been tested and are recommended for printing the C160.

Other materials may also work, but they have not yet been tested.

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?

It is possible to assemble the telescope in under two hours. The exact time varies depending on your skill level and pace. The current record is 54 minutes 😄

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.
