DWARF II. A new way to look in the sky.

Reading Time: 3 minutes

Every astronomy enthusiast who likes to look at celestial bodies in the sky understands that such a telescope can be quite expensive. Moreover, traditional telescopes are large, heavy, and not mobile enough. This is why the DWARF II telescope was created by TinyScope CAM, which enables users to pursue their interests without difficulty. This smart telescope gives users incredible detail of an object, at the same time being extremely small in size.

The developers took into account all the shortcomings of the previous model DWARF I and created an improved version of the telescope, which is so beloved by users. Moreover, they added the ability to control the telescope using a cell phone. The developers also said that in the nearest future they will provide API and documentation for developers. So they will allow users to develop and run their own programs on DWARF II.

Developers claimed that this cutting-edge telescope is able to take pictures of objects located deep in space, and moreover, it is even capable of taking photos of other galaxies. Due to the diagonal of the sensor of the IMX415 telescopic camera, the diagonal of the 35mm frame is approximately 6.7. Thus, on a 35mm camera, this 100mm lens is approximately equivalent to a 675mm lens. The Developers say that this should be enough for taking fantastic pictures of the Moon and other bigger galaxies. DWARF II can capture multiple images using 2-axis scanning technology and, later, stitch them together to form one image. In this case, The number of pixels can even reach one billion.

DWARF II is compact, and has the following technical characteristics:

Lens: 100 mm focal length, is optimized to the diffraction limit

Motor: 0.001°/s~36°/s ultra-wide speed range, high-precision positioning

Sensor: SONY IMX415 Starvis, 8 million pixels, high sensitivity

CPU/NPU: 4-Core Cortex-A7 1.5 GHz CPU, 2 TOPS NPU

To take a photo of any deep-sky object, traditionally, astronomical observation telescopes must be equipped with an equatorial instrument and a camera. All these equipment prices start at $1500 and can be even higher. So, it can be concluded that for ordinary users it will be quite costly. Whereas, DWARF II early bird price starts from $459.

Summarizing everything that was mentioned before, It must be said that DWARF II is an awesome, light, user-friendly, and compact telescope. In comparison with traditional equipment, it is very cost-effective. Moreover, it allows users to develop custom software, using their API. And in my opinion, this advantage allows them to gain experience that simply can not be achieved with traditional telescopes.

The beginning of the construction of the largest optical telescope in the world

Reading Time: 3 minutesA promise to open the door to new astronomical research. Mountain Mauna Kea on the island of Hawaii, Australia, South Africa, northwestern China, as well as the Atacama desert, located in Chile, the climate in these areas will be built immediately after several installations. vast expanses of space, but also consider.

One of such facilities will be the Extremely Large Telescope (ELT) of the European Southern Observatory – the largest optical telescope of the new generation, equipped with a complex composite mirror with a diameter of 39 meters.

The main phase of the construction of the ELT began in May 2017, after several years of disputes and discussions on this topic. The object will be released in 2024. The total cost of the project is estimated at 1.12 billion dollars. In 2018, the cost of the telescope is 1.23 billion dollars. According to the latest forecasts, by 2024 the cost of the entire project should be about 1.47 billion dollars (with a inflation rate of 3%).

The construction of such a system is necessary in a higher region, where the effectiveness of observers will not depend on changes in the atmosphere and light pollution. The construction site must have an ideal flat surface. In search of years, the European Southern Observatory in this place and eventually decided to create their own – on top of Mount Armasones in Chile. As seen in the photos below, the builders have already laid the foundation for the future telescope.



The capabilities of the ELT will be in its main mirror, which will be constructed from 798 hexagonal parts, each with a diameter of 1.4 meters. A huge 39-meter mirror will be assembled from these pieces, which will receive data with the highest level of quality that none of the existing telescopes are capable of.


For example, the Very Large Telescope (VLT) – currently the largest and most technologically advanced optical telescope – is a design of four auxiliary 1.8-meter optical telescopes and four separate 8.2-meter telescopes, connecting in one system. The angular resolution of the VLT was equivalent to a telescope with a solid mirror up to 200 meters. The viewing area will be a hundred times larger, it will be able to observe immediately a huge number of light sources, also noting objects with a significantly lower level of brightness, which current telescopes are not capable of observing.

The resulting images will not need serious processing because the ELT diaphragm will be inseparable. According to the engineers, the ELT will be 200 times more efficient than the Hubble, making it the most powerful telescope operating in the infrared and optical ranges.

Project developers note that due to adaptive optics
and ELT will be able to conduct a direct observation of exoplanets located in the orbits of distant stars, which is currently very rare among current telescopes.


Due to the fact that the telescope will actually be the most powerful in its class and will be able to carry out observations on the partial for stony exoplanets, then one of its tasks will be to study the worlds of the atmosphere.
And this is not all of its potential opportunities. For example, with the help of this telescope, scientists will be able to directly measure the rate of expansion of the Universe, find out the role of dark energy in the evolution of space. There is an opportunity to more accurately study the past of space, astronomers will be able to create more accurate models of step-by-step development of the Universe.
