Optics and optimism: An inventor in Okara

Here’s looking at you kid A view of the moon’s craters Asad with his telescope

Al Battani would be proud. The 9th Century astronomer, who determined the length of the solar year, was also a skilled maker of astronomical instruments and gave us a blueprint of the sundial. The same ingenuity is reflected in Asad Mehmood, an unlikely inventor who has made the sixth most powerful telescope in Pakistan – all from items available in his native town of Okara.

Asad Mehmood’s story is one of ingenuity and improvisation. A pre-engineering student in the District Public School and College Okara, Mehmood has been fascinated with optics ever since he was introduced to the subject in Class 6. “I used to play with convex and concave lenses and perform a lot of experiments, just for fun,” he reminisces. “At that time, I didn’t even know about telescopes, their working or their internal structures.”

While many of us grow out of our childhood fancies, Mehmood’s interest in optics only grew with time, and he started doing some serious reverse engineering. “I not only bought lenses from optics shops but more frequently I got magnifying glasses from bookstores. Then I bought a toy telescope, checked out its internals and made another one identical to it.”

The success of this first invention spurred him on. Not content with toy telescopes, he says, “that was when there rose in me the ambition to build a telescope to view the sky and the moon, the stars and planets.”

But dreaming was one thing, actually building a working telescope quite another. Mehmood had never seen a real telescope in his entire life. There was no astronomy society in Okara that he could turn to; he didn’t even have an internet connection that he could use for research. Still, though he loathed reading, he pored over the books in his school library, reading every scrap of information he could find on astronomy, lenses and optics.

“Fortunately I found a book that dealt with the topic ‘light’, which was exactly what I wanted. I gathered a lot of information about telescopes.”

After a year of failed prototypes, he made a Galilean Telescope, consisting of two convex lenses placed at a specific distance to each other. At that time, he was in Class 8.

Holed up in his room for days on end, he toyed with the magnification and resolution of his telescope, taking great pains to bring small improvements to his design. The same year he also built a low-cost microscope that had the magnifying power of a lab microscope, despite never having seen a lab microscope in his life.

Soon, he found himself fascinated with Newtonian telescopes that consist of a primary parabolic mirror, a plane mirror strip and an eyepiece — all in his head, of course, since there was no question of gaining access to an actual Newtonian telescope in Okara. These reflecting telescopes offer the possibility of high quality images with very little blurring. And Mehmood was already raring to make one — now the challenge was to get a parabolic mirror. Mehmood was ready to do anything to get such a mirror, but parabolic mirrors for Newtonian telescopes were not to be had in Okara.

Finally, he got his lucky break. The Khwarizmi Science Society, a Lahore-based astronomical society, arranged a space observing event at Mehmood’s school. For the first time in his life, Mehmood saw a reflecting telescope, and observed the heavenly bodies. Wonderstruck by that experience and freshly inspired, his resolve to build a similar telescope only grew stronger. This was also the time when he met Ali Khan, a member of the Khwarizmi Science Society. After a barrage of questions from the fledgling astronomer, Khan was impressed by the boy’s zeal but told him that to build his telescope he would have to make his own optics and the task seemed impossible to him. Still, Khan was obliging enough to rake the markets of Lahore for the material required to make the telescope.

In his first year of F.Sc pre engineering part 1, Mehmood started work on the Newtonian Telescope.

First, he had to grind a thick glass and convert it into a concave lens. This was tricky and laborious business but he kept at it day and night, grinding the glass with his own hands, YouTubing videos (he now had an internet connection), making mistakes, and starting over. The failures he faced during this time would have discouraged anyone, but at no point did Mehmood even consider the possibility of failure. His family encouraged him, particularly his father, who would try to provide Mehmood any materials he needed for his experiments. Six months later, he was done with the first phase of his telescope.

Now the next step was to polish the mirror. The concave lens that he had ground and refined had to be converted into a smooth and polished surface. This was a delicate task but finally, a year and 9 months after he first embarked on the project, the glass had gained a fine parabolic concave curve.

He then fashioned the body of his Newtonian telescope with a PVC pipe: installing the mirror, adjusting the plane mirror strip and installing an eyepiece. He designed a stand on which to mount his creation, one which would not only bear the weight of the telescope but would also allow for up-down and left-right movement. Then he lovingly painted it. Asad Mehmood, FSC student from Okara, had just made the 6th most powerful telescope in the country!

Mehmood’s telescope is capable of viewing clear, magnified images of the moon’s craters, Jupiter, (along with its four moons), Saturn and Venus. This telescope magnifies images to 300 times the size visible to the naked eye. Incidentally, Mehmood is the first to build a telescope of this kind in Pakistan.

So is he now basking in his glory? No, the ‘Junior Scientist’ — as he has affectionately been nicknamed by his teachers and classmates — already has his eyes set on his next project: building Pakistan’s largest telescope and he is quite confident that he can do it. And so are we!

    And a piece of advice:
    Never fall for the traps like “Pakistan’s 6th biggest”, and “first time in world”, etc. These things may kill your creativity and soon you may find yourself burned out by a pointless race to “make records” instead of doing original science or engineering”. Good science comes out of creativity and ingeniousness. Records are made as a result of lucky accidents (a side-product).

    This was just a nice experiment. I did nothing extra ordinary. I want to tell you all that I am anxiously looking for a glass factory which can prepare a glass blank of 25″ diameter and 3″ thickness for me. To build this 25″ telescope is my current dream. In my city, there is no question for a glass factory. And in other cities, I’ve no Idea. So I would be thankful if someone helps me regarding this matter. Thanks.

    Dear Asad Mehmood,
    Congratulations. May the Almighty guide and help you in your future endevours. People like you are the real hope for Pakistan.
    Reading the newspaper piece was a kind of window into my own past where I experimented a lot with lenses and mirrors. Unfortunately, I did not enjoy the moral support of my family on these issues, neither did I have the funds to buy the equipement that I wanted to.. but in the end, I guess I just did not have the resolve that you certainly have.
    Keep it up and never quit.

    @Asad Mehmood, you are always welcome. Brilliant work. You make us proud. Pakistan Zindabad. I hope others follow you and wish you success in all future projects.
    I suppose credit also goes to atm_free@yahoogroup.com experts Mark, Jerry , Bethold and many others who helped freely at every step particularly during the tricky parabolizing stages, to stellafane.org for diagrams etc, to Irshad Sahib who also guided you in polishing and to Zafar Sahib of Islamabad who gave a reflective aluminum coating to your mirror and secondary free of cost and also to your Dad and your family for their constant monetary and moral support and your College Principal and Umair Asim sahib who each donated a powerful microscope eyepiece for your project.
    I also think that this a a very doable project and each young individual must take it up and thus gain respect for accuracy, be proud of his or her efforts and finally enjoy the views of our beautiful and grand universe.

  • Aug 29, 2011 - 11:44PM

    Congratulations dear Asad. Indeed this is a great achievement. Grinding a mirror is labourious but parabolising and polishing is loads of patience. In my youth I was frustrated by the lack of optical material and technical assistance, yet was able to ground a mirror but could not get it aluminised. My advice is to go for a 12″ Dobsonian now. You will get tons of experience with it. Moreover it would be portable enough to carry around. Congratulations are also due to Ali Khan, whose motivation, experience and guidance made it possible.

    Note: At international Erina mostly people (Scientist) are called by their family name (surname). That is the reason they have narrated in that manner. you must not care about these small things rather you have a great brain to be proud of.
