PiScope is an open source project to do basic astrophotography using a RaspberryPi, Arduino, 3d-printed parts, and a telescope. When it is done we hope to have autotracking via OpenCV working and at the moment can use a keyboard to jog the telescope view, take photos, take videos, and stream images to a laptop via a wifi hotspot. It also has a neat little screen where everyone can see the eyepiece view. This is quite handy for star parties.
Lots of people pitched in to make this happen and was quite a fun project to work on — some woodwork, 3d design, printing, electronics, software all mixed together to make this work. Here are some very early photos taken with the PiScope. Note: The image quality is not indicative of what PiScope is capable of.

Wed 22 July By Toby Kurien Electronics open source github electronics house4hack making raspberry pi arduino piscope astronomy.The history of the telescope can be traced to before the invention of the earliest known telescopewhich appeared in in the Netherlandswhen a patent was submitted by Hans Lippersheyan eyeglass maker.
Although Lippershey did not receive his patent, news of the invention soon spread across Europe. The design of these early refracting telescopes consisted of a convex objective lens and a concave eyepiece.
Galileo improved on this design the following year and applied it to astronomy. InJohannes Kepler described how a far more useful telescope could be made with a convex objective lens and a convex eyepiece lens. Byastronomers such as Christiaan Huygens were building powerful but unwieldy Keplerian telescopes with compound eyepieces.
Isaac Newton is credited with building the first reflector in with a design that incorporated a small flat diagonal mirror to reflect the light to an eyepiece mounted on the side of the telescope. Laurent Cassegrain in described the design of a reflector with a small convex secondary mirror to reflect light through a central hole in the main mirror. The achromatic lenswhich greatly reduced color aberrations in objective lenses and allowed for shorter and more functional telescopes, first appeared in a telescope made by Chester Moore Hallwho did not publicize it.
John Dollond learned of Hall's invention   and began producing telescopes using it in commercial quantities, starting in A number of 4-metre class inch telescopes were built on superior higher altitude sites including Hawaii and the Chilean desert in the — era.
The era of radio telescopes along with radio astronomy was born with Karl Guthe Jansky 's serendipitous discovery of an astronomical radio source in Many types of telescopes were developed in the 20th century for a wide range of wavelengths from radio to gamma-rays.
The development of space observatories after allowed access to several bands impossible to observe from the ground, including X-rays and longer wavelength infrared bands. Objects resembling lenses date back years although it is unknown if they were used for their optical properties or just as decoration.
Actual use of lenses dates back to the widespread manufacture and use of eyeglasses in Northern Italy beginning in the late 13th century. The first record of a telescope comes from the Netherlands in It is in a patent filed by Middelburg spectacle-maker Hans Lippershey with the States General of the Netherlands on 2 October for his instrument " for seeing things far away as if they were nearby ". The States General did not award a patent since the knowledge of the device already seemed to be ubiquitous   but the Dutch government awarded Lippershey with a contract for copies of his design.
The original Dutch telescopes were composed of a convex and a concave lens —telescopes that are constructed this way do not invert the image.
Who Invented the Telescope?
Lippershey's original design had only 3x magnification. Telescopes seem to have been made in the Netherlands in considerable numbers soon after this date of "invention", and rapidly found their way all over Europe.
In Dutch diplomat William de Boreel tried to solve the mystery of who invented the telescope. He had a local magistrate in Middelburg follow up on Boreel's childhood and early adult recollections of a spectacle maker named "Hans" who he remembered as the inventor of the telescope. The magistrate was contacted by a then unknown claimant, Middelburg spectacle maker Johannes Zachariassen, who testified that his father, Zacharias Janssen invented the telescope and the microscope as early as This testimony seemed convincing to Boreel, who now recollected that Zacharias and his father, Hans Martens, must have been who he remembered.
In the minutes of the Royal Society in London Robert Hooke noted Thomas Digges ' Pantometriaa book on measurement, partially based on his father Leonard Digges ' notes and observations seemed to support an English claim to the invention of the telescope, describing Leonard as having a fare seeing glass in the mid s based on an idea by Roger Bacon.For those who prefer to look up at the sky rather than down at your feet, a telescope may be a worthwhile investment.
It can provide you with a lifetime of entertainment as you observe the ever-changing universe and deepen your understanding of its intricacy and beauty. Astronomy is as old as mankind and purchasing a telescope lets you inherit a legacy spanning thousands of years. A telescope gives you the opportunity to see galactic phenomena that would otherwise be invisible to the naked eye from the comfort of your own home. From stargazing to planet watching and satellite spotting, a multitude of activities become readily available to you weather permitting.
PiScope Raspberry Pi Optical Tracking Telescope Created
If you have a child, a telescope can be a great birthday gift, and it will allow you to bond over your mutual fascination for the mysteries of the cosmos. Serving both educational and recreational purposes, a telescope is a must-have for amateur astronomers and physics enthusiasts alike.
In this digital age, it grants one the much-needed ability to reconnect with nature. There are three basic types of telescopes: refractors, reflectors, and catadioptric telescopes. Each one uses different optics in order to magnify distant objects, refractors being the most common. The most important thing to look out for when buying a telescope is the diameter of the aperture, as this will determine what celestial bodies you can actually see and their level of detail.
Often overlooked, the sturdiness of the mount will also heavily impact your viewing experience. Mounts include the altitude-azimuth which is the most similar to a photo tripod, and the equatorial mount which provides tracking capabilities. Skip to main content. More options available.

Previous Page 1 2 Telescopes For those who prefer to look up at the sky rather than down at your feet, a telescope may be a worthwhile investment.The telescope is one of humankind's most important inventions.
The simple device that made far away things look near gave observers a new perspective. When curious men pointed the spyglass toward the sky, our view of Earth and our place in the universe changed forever. But who invented the telescope? The answer remains a mystery today. It was probably inevitable that as glassmaking and lens-grinding techniques improved in the late s, someone would hold up two lenses and discovered what they could do.
The first person to apply for a patent for a telescope was a Dutch eyeglass maker named Hans Lippershey or Lipperhey. InLippershey laid claim to a device that could magnify objects three times. His telescope had a concave eyepiece aligned with a convex objective lens. One story goes that he got the idea for his design after observing two children in his shop holding up two lenses that made a distant weather vane appear close.
Others charged at the time that he stole the design from another eyeglass maker, Zacharias Jansen. Jansen and Lippershey lived in the same town and both worked on making optical instruments.
Scholars generally argue, however, that there is no real evidence that Lippershey did not develop his telescope independently. Lippershey, therefore, gets the credit for the telescope, because of the patent application, while Jansen is credited with inventing the compound microscope. Both appear to have contributed to the development of both instruments. Compounding the confusion, yet another Dutchman, Jacob Metius, applied for a patent for a telescope a few weeks after Lippershey.
The government of the Netherlands eventually turned down both applications because of the counterclaims. Also, officials said, the device was easy to reproduce, making it difficult to patent.
In the end, Metius got a small reward, but the government paid Lippershey a handsome fee to make copies of his telescope. InGalileo Galilei heard about the "Dutch perspective glasses" and within days had designed one of his own — without ever seeing one. He made some improvements — his could magnify objects 20 times — and presented his device to the Venetian Senate. Galileo was the first to point a telescope skyward.
He was able to make out mountains and craters on the moon, as well as a ribbon of diffuse light arching across the sky — the Milky Way. He also discovered the rings of Saturn, sunspots and four of Jupiter's moons. Thomas Harriot, a British ethnographer and mathematician, also used a spyglass to observe the moon. Harriot became famous for his travels to the early settlements in Virginia to detail resources there. His August drawings of the moon predate Galileo's, but were never published.
The more Galileo looked, the more he was convinced of the sun-centered Copernican model of the planets. But his ideas were considered heretical, and Galileo was called to appear before the inquisition in Rome in He struck a plea bargain and was sentenced to house arrest, where he continued to work and write until his death in Elsewhere in Europe, scientists began improving the telescope. Johannes Kepler studied the optics and designed a telescope with two convex lenses, which made the images appear upside down.
Working from Kepler's writings, Isaac Newton reasoned it was better to make a telescope out of mirrors rather than lenses and built a reflecting telescope in Centuries later the reflecting telescope would dominate astronomy. The largest refracting telescope one that use lenses to gather and focus light opened at Yerkes Observatory in Williams Bay, Wisconsin, in But the inch 1 meter glass lens at Yerkes was soon made obsolete by larger mirrors.

The PiKon hardware kit and design are undergoing an upgrade. The printed case support also fits Pimoroni cases for the Raspberry Pi 4 which is different to the Pi 3 and previous Pi cases.
He has completely motorised the PiKon, even down to the focusing mechanism. YouTube Link. The exhibition continues in Bradford England until January The idea was to show the citizen scientist, maker or enthusiast just what could be done with disruptive low cost technologies.
The project combined affordable 3D printing with the low Raspberry Pi computer and its camera. For the best images, it good to get the axis of the parabolic mirror lined up with the axis of the PiKon tube.
You can do this in 2 ways:. One you have built the mirror assembly you can ensure that the spring loaded adjustment bolts are set right by trapping a 5mm or similar drill bit between the mirror mount 3D printed part and mirror base 3D printed art.
By positioning the drill bit near each of the springs and adjusting the bolt until it just releases, you will get the mirror reasonably aligned. In normal use this would slot into the eye piece of a telescope and bounce a laser beam off the primary and secondary mirror.
There is a target in the device set at 45 degrees where the laser beam is aimed during adjustment of the mirror. There is no eye piece in the PiKon, so we have just made a 3D printed alignment tool available.
It is then a matter of adjusting the spring loaded adjustment bolts until the laser beam, which is reflected off the mirror, hits the centre of the target on the laser collimator.
