If there is a field you might not expect to do by crowdsourcing, it might be space exploration. But this is exactly what the Open Space Agency (OSA) is doing. OSA is a network of amateur citizen scientists founded by entrepreneur James Parr who position themselves as a complement to professional space agencies. The agency is even working on its own space project, the open source 3D printing telescope Ultrascope, an automatic astronomical telescope built on 3D printing, controlled by a smartphone.
In fact, we have introduced the Ultrascope project many times in the past, and as early as 10 in 2014, it started beta testing. Since that time, Ultrascope has been continuously improved as an open source 3D printing design by the OSA community. Until now, OSA officially released the official version of the open source 3D printing astronomical telescope, Ultrascope Explorer Plus, through Wevolver. According to Parr, using a 3D printing and laser cutting technology, the cost of the astronomical telescope is only about £200.
However, OSA did not release all the build instructions for Ultrascope Explorer Plus at once, but hoped to release a part of it later. Step 1 just released includes all design files for the parts manufactured by 3D printing and laser cutting technology; steps 2-5 relate to how to make focusing devices, telescope tubes, optical paths, split rings and pedestals; It mainly consists of the assembly of electronic devices, including the Arduino circuit board as the "brain" of the telescope; step 7, and the final step, to observe the celestial body.
This is an astronomical telescope that anyone can build and use in his backyard. But its functionality has gone beyond the scope of being just a tool for an amateur astronomer. Using a smartphone as a camera and input/output device, Ultrascope enables amateur astronomers to capture and measure, effectively providing useful data for discovering scientific applications such as asteroids or planets.
“Interestingly, some of the off-the-shelf product technologies that consumers use today are starting to approach the level of expertise of a decade ago,†Parr said. “The camera on NASA's Mars probe and the camera on a contemporary smartphone. The quality is basically the same. The rapid development of current consumer technology has made me almost curious to use the off-the-shelf technology on the market to achieve or replicate the results of some space programs."
In fact, OSA believes that Ultrascope and its users will be able to play an important role in NASA's Asteroid Challenge Lab project. NASA's project encourages citizens to help identify asteroids that may pose a potential threat to the planet. Is it very attractive? Create an Ultrascope and you might even save the world!
So how do Ultrascope users share the photos, measurements, and observations they capture? Of course it is cloud computing! A smartphone app can record the photos and information obtained by the telescope and send it to a cloud database where anyone can access the database. At the same time, the app also records the location of each Ultrascope. So, as more people make and use this astronomical telescope, a global astronomical observation network is formed.
"When we have thousands of Ultrascopes in use around the world, you can say, "Oh, I want to know what the sky in South Africa will look like. "Then you can connect to the telescope in South Africa and see what it sees," Parr added.

1)Ideal cold light effects
Using the new LED cold light source, ensure energy saving and environmental protection and long service life up to 80,000hours and more.
The temperature increase of surgeon`s head below 1℃. LED do not engender infrared ray and ultraviolet radiation, without the temperature
rise and tissue damage caused by halogen shadowless light, also it can accelerate the wound healing after surgery, and without Radiation pollution.
With color temperature constant and soft, LED is very close to the sunshine.
1) Excellent shadowless effect
Lamp with the most scientific radian and Multi point light source design, ensure better uniform illuminance. When the lamps are partially occluded,
also can achieve perfect shadowless effect.Lamp panel radius of gyration ≥182cm, the lamp can be pulled to vertical floor, convenient to any angle illumination.
2) Excellent deep lighting
It is based on modularize method by Computer Aided Design, focused to irradiating with more beams of LED. It produces the deep lighting which beams
more than 1200cm,the illumination of center up to 180,000Lux or more, and offer the color temperature that can be adjusted from 3700K to 5000K which
is close to sunshine. Absolutely, it really reflects the color of human tissue and satisfied by all kinds of operating light needs.
3) Advanced control system
The use of liquid crystal display button control, to meet the needs of the medical staff of different patients with the brightness of the operation.
It offers illuminance memory function.
It does not effect using when a single circuit or one bulb is broken.
4) Universal suspension system
Rotating arm, a new type of alloy material is made of eight edge type.
Balanced system using imported arm module, more than 5 group universal joints, every cantilever must has more than 3 joints which can be rotated in 360°,
The structure is light, easy to manipulate, accurate positioning, can provide the maximum range of regulation.The equipped with fatigue correcting unit and
fix position hand handle device, easy to fix position after long time use.
5) Modern laminar lamp
The thickest part of lamp-chimney is not more than 10cm.
The lamp-chimney is made of ABS, The handle on the central of lamp can be detachable, can take high temperature (≤ 134°C) sterilization treatment,
easily adjust, flexible fixed.
