February 2023 marked a small but significant turning point in our journey at CSTERC Techno Science LLP.

For years, we had been conducting telescope construction workshops in schools and colleges, taking students through the fascinating process of building their own telescopes. We had learned by doing—cutting tubes, working with mirrors, assembling optical systems, solving problems along the way, and, most importantly, understanding what it takes to turn a collection of components into a working telescope.

But somewhere along that journey, another question began to emerge.

What if we could build these telescopes ourselves—not just as a workshop activity, but as a product that more people could actually afford?

That question eventually led us to a rather unconventional place: Bharath’s home in Elachipalayam, Namakkal.

And that is where our first telescope factory began.

A Factory That Didn’t Look Like a Factory

It was not a large industrial facility. There was no production line, no polished factory floor, and certainly no impressive signboard at the entrance.

It was a home-brew telescope factory—an experimental production setup created with whatever space and resources we could put together.

Bharath, one of the founding members of CSTERC Techno Science LLP, took the responsibility of managing the telescope production and quality checks. His home gradually became a place where ideas, tools, metal tubes, mirrors, paint, and plenty of experimentation came together.

We purchased a few basic machines that allowed us to cut and work on the telescope tube assemblies more precisely. We experimented with welding, fitting, grinding and finishing. Slowly, the space started to resemble a small telescope workshop—and eventually, our first telescope production setup.

The objective was simple:

Build good-quality telescopes, keep them affordable, and learn how to produce them ourselves.

From Teaching Students to Building for Them

Our telescope construction workshops had already taught us something important: there was genuine interest in astronomy and telescopes, but affordability remained a major barrier.

A telescope can open an entirely different window to the universe. But for many students, schools, families and amateur astronomers, commercially available instruments can be expensive.

We wanted to explore whether there was another way.

Instead of simply importing or assembling everything, could we develop the capability to manufacture important parts ourselves?

The answer would take time. But the first step was to begin.

So, in early February 2023, we started experimenting.

Cutting, Grinding, Welding and Painting

The new setup became a place of constant activity.

We cut the telescope tubes to the required dimensions. We worked on the tube assemblies and experimented with welding and fabrication. We ground the mirrors and worked on the optical components. We painted the telescope tubes and assembled the different parts into complete instruments.

Nothing was perfect in the beginning.

Every telescope taught us something new.

A cut that needed to be more precise.
A joint that needed better finishing.
A mirror that required more careful handling.
A tube assembly that needed another modification.

This was not merely manufacturing.

It was engineering through experimentation.

Even today, when we look back at those first telescopes, there is something wonderfully human about them.

While painting our first telescope assemblies, our fingerprints were literally left on the tubes.

Those marks were not imperfections we wanted to hide. They were reminders of where we had started.

These were telescopes made by our own hands.

Building the Capability One Component at a Time

We were not manufacturing every component ourselves from day one.

Some parts still had to be sourced from outside, particularly specialised components such as eyepieces. Developing every component internally requires different kinds of machinery, expertise and investment.

But we saw that as part of the journey rather than a limitation.

Our immediate goal was to develop the capability to manufacture and assemble the major telescope structures ourselves, while continuously improving our processes and quality.

And somewhere in that workshop, another dream quietly took shape:

One day, we would make our own eyepieces too.

Perhaps that sounds like a small ambition. To us, it represents something much bigger—the gradual transition from being telescope users and workshop facilitators to becoming telescope builders and eventually telescope manufacturers.

The Beginning of a Bigger Dream

The first telescope factory in Elachipalayam was never intended to be the final destination.

It was our proof of concept.

It was where we tested whether our ideas could actually work. It was where we learned how to turn workshop experience into a repeatable production process. It was where we began thinking seriously about quality control, manufacturing precision, affordability and scalability.

Most importantly, it gave us confidence.

We had started with telescope construction workshops.

Then we began building telescopes with students.

And now, we were building telescopes for others.

That progression represented an important change in CSTERC’s journey.

The dream was no longer simply to teach people how a telescope works.

The dream was to build telescopes that could put the universe within reach of more people.

A Small Room, A Big Dream

Looking back, the Elachipalayam setup may seem modest compared with what we eventually hope to build.

But every large manufacturing facility begins somewhere.

Ours began at home.

With a few machines.

With tubes and mirrors.

With experiments that sometimes worked and sometimes didn’t.

With Bharath taking responsibility for production and quality.

With our hands covered in dust, metal particles and paint.

And yes—with our fingerprints still visible on some of those very first telescopes.

That is what makes the beginning special.

Before there was a telescope factory, there was a dream.

In February 2023, in a home in Elachipalayam, Namakkal, we took one more step toward turning that dream into reality.

And this was only the beginning.

Someday, we hope to look back at that small home-brew setup and remember it as the place where the CSTERC telescope manufacturing journey truly began.
