Get the Most out of Your Universe2go with Our Tutorial Videos!

January 9 2018, Joshua Taboga

For those, getting started with Universe2go or trying to troubleshoot, check out these helpful tutorial videos to help you get the most out of your Personal Planetarium.

Getting Started

With Universe2go, getting started is quick and easy.  The app set-up is straightforward and learning how to navigate the menu takes only a few minutes.

First make sure that you have the Universe2go packaging on hand.  Inside the top lid, you will find the activation code for Planetarium Mode.  After starting Planetarium Mode for the first time, follow the steps on the screen and then let the narrator guide you through navigating the planetarium and menu.  Focusing on an object provides you with a wealth of info about that object and the app will track your head movements in relation to the stars in the night sky.

Look down to activate the menu.  Don’t forget to keep your head level and use only small movements when navigating the menu.

Star Calibration

The star calibration takes place only at night, and three prominent stars should be visible.

Passepartout Customization

The passepartout secures your phone within the goggles.  The adhesive makes the placement of the foam pieces permanent.  If you would like to use multiple phones with Universe2go, we recommend keeping the paper on the foam pieces.

Eye Calibration

Eye calibration allows you to readjust the dual screens on your smartphones display to fit your eyes.  Sure beats seeing double!


Infographics: Astro highlights for winter

January 3 2018, Marcus Schenk

The new astrological calendar for the next three months summarised in graphic form. The astronomical infographic, “Highlights in the winter sky”, shows you at a glance what is going on in the sky. The following text will tell you more about some of the events taking place.

08.12. Moon obscures Regulus
At the beginning of September, the waning moon will obscure the bright star, Regulus, in the constellation of Leo. It is a noticeable event because Regulus, at 1.3 mag, is one of the brightest stars in the sky. Binoculars or a small telescope are sufficient to follow this event. But: You need a good view of the north-east horizon. The best thing to do is observe from a wide open space or from a raised point. It is important that there are no houses or trees that could block your view.

13.12. Moon meets Mars
The slim crescent of the waning moon will meet up with Mars before sunrise. It is currently at a distance of 6 degrees. There are, however, more things to discover: These two heavenly bodies plus the star, Spica, form a triangle. A little lower down, on the horizon, you will be able to see Jupiter. It almost looks as if all heavenly bodies are forming a kind of arrow that extends towards the horizon.

14.12 Geminids
If the evening sky is clear, look towards the south. The “Geminids” meteor shower can be seen coming out of the constellation of Gemini. To be more precise: From a point two degrees above the star, Pollux. Between 21:00 and 6:00 is the best for observing. The Geminids, with 120 meteors per hour, is one of the meteor showers with the highest incidence rate. This year, however, the full moon will obscure the view somewhat. However: You should not miss this event.

21.12. Winter solstice
Every year, on 21 or 22 December, we have the shortest day and the longest night. On 21 December, winter starts and the sun sets at 16.21. Night-time lasts around 12 hours. This is a dream for amateur astronomers who want to stay out observing the sky for a long stretch.

31.12. Moon obscures Aldebaran
Just before New Year, during the night from 30 to 31.12, the moon obscures the star, Aldebaran. It is the main star of the constellation of Taurus, and is one of the brightest stars in the sky. That is advantageous because the occultation of bright stars is fascinating. We almost have a full moon, but the moon gets closer to Aldebaran from its darker, interesting side. Aldebaran disappears around 2:25 and then reappears 30 minutes later on the opposite side of the moon.

01.01. Mercury in its largest westerly elongation
Mercury goes around the sun so quickly, and so close to it, that we cannot observe it all the time. But Mercury is now once more at a larger angle distance of 22° to the sun. In the morning sky, the rare guest rises around 6.30 in a south-easterly direction. Soon after that, however, sunrise starts and it fades as day commences. Luckily, Mercury is quite bright, and can, therefore, be seen until around 7.30. If it is cloudy over the New Year, you can still observe Mercury until 10 January.

03.01. Quadrantids
The next meteor shower is on its way to us: the Quadrantids. This meteor shower comes from the Boötes constellation. The meteor shower continues at a rate of 120 per hour across the sky. If you observe during the early hours of the morning between 2 and 3 January, you will have the greatest chance of having a successful session.

07.01. Mars meets Jupiter
On the morning of 7 January, two neighbours meet: Mars and Jupiter. In the middle of the constellation of Libra, they both light up very brightly at a distance of just 12 arc minutes. This is just a little over a third of the diameter of the moon. You can observe both of these planets on this day together with your telescope in the same field of view.

11.01. The meeting of the moon, Mars and Jupiter
A few days later, in the same region: Mars and Jupiter start to move away from each other again. But on this morning, the moon joins in the fun. The narrow crescent shines a good three degrees above the planets. Even if you’ll have to wrap up warm on this morning, this wonderful view will melt any ice.

13.01. Mercury meets Saturn
Mercury gives us one last opportunity before leaving the stage and steps out into the limelight. On this morning, however, it lets us see it with Saturn. Just before sunrise, both of these journeymen appear over the horizon in a south-east direction.

31.01. Ceres in opposition
Ceres is one of the most well-known but smallest of the dwarf plants in the solar system measuring just 963 kilometres in diameter. It goes around the sun in the asteroid belt between Mars and Jupiter about every 5 years. On 31 January, it will be in opposition to the sun and you can observe it in all its brightness. With brightness magnitudes of 6.9, it moves from the head of Leo between the constellations of the Lynx. You can find it with a telescope or even with binoculars.

01.02. Moon meats Regulus/Mars meets Acrab
If you like observing during the early hours of the morning, there is an interesting event during this night. At around 4.00, the pincers of Scorpio rise over the south-east horizon. There is something there, of course: Mars. The red planet goes past Acrab at a distance of just 18 degrees to the left.

And on the following evening, the moon goes past Regulus – the main star in the constellation of Leo – at a distance of just 7 arc minutes. The time for a meeting is favourable: At 19.00, the moon reaches the smallest distance.

08.02. Moon obscures γ Lib
This occultation will probably not be followed by a lot of observers, because it takes places in the sky in the early hours of the morning. When most people are still warm in bed. This makes this occultation of the star, γ Lib, by the moon in the constellation of Libra, a rarely observed event. The moon is 45% illuminated and approaches the star from its “bright” side. At 4:20, the star disappears behind the moon and at 5:30 is reappears on the non-illuminated side.

11.02 Moon meets Saturn
The moon likes to pay the occasional visit or two to our planets. On 11 February, it will be visiting Saturn again. Such encounters always make an enticing spectacle. And a beautiful occasion for an atmospheric photo with a standing camera and lens. The moon is around 3.5° higher in the sky, so you will see it first. At around 5.00, Saturn peers over the horizon. It is actually not the best time for the ringed planet. In the coming months, it doesn’t come up until the second half of the night. It doesn’t start to rise at a more pleasant time until the approach of early summer. In June, it is then in opposition to the sun.

21.02. Moon obscures μ Cet
An occultation in the evening sky: And that’s before the news! At 18.20, the moon obscures the star, μ Cet, in the constellation of Cetus. After a good hour, around 19.17, the star rises again on the other side. This time, the moon approaches from its non-illuminated side. If you observe the star, it disappears so quickly it looks like someone just switches it off.

23.02. Moon obscures Aldebaran
A highlight is the occultation of Aldebaran. Like last December, you should not miss this event, because occultations like this are extremely rare. It is the last occultation for many years.

The moon approaches from its dark side. For many observers, it is surprising that the star disappears suddenly even though they are expecting it. Things get going at 17.50: Aldebaran disappears and then reappears at 18:50, a good hour later. It is interesting for amateurs to observe star occultations from the beginning to the end, monitoring the time accurately. This is possible, for example, with sensitive Touptek cameras and SharpCap 2.7 software, with which you can add a precise time signal.

The team of wish you much enjoyment observing and clear skies.


Merry Christmas!

December 22 2017, Marcus Schenk

The delicious aroma of Advent cookies is everywhere. Wherever you look, stars and Christmas lights are shining in windows. But, of course, as astronomers, we are not only interested in these earth-bound lights, but also in the stars in firmament. We have launched interesting new products under the Omegon brand this year to help you do this even better:

Our new, waterproof Omegon Panorama II eyepieces give you a wide 100° field of view to better enjoy the stars. Astronomical objects appear in a completely new light!

Omegon Panorama II Okulare mit 100° Gesichtsfeld
The new Omegon ADC Atmospheric Dispersion Corrector lets you take sharp planetary photos and reduces colour fringing.

Omegon ADC Atmospheric Dispersion Corrector
Another highlight for astrophotographers is our new released Omegon RC telescopes and fast astrographs.

Omegon RC-Teleskope
Our excellent ProDob Dobsonian telescopes – from 8 to 16 inches in aperture – will bring a gleam to the eyes of many visual observers.


This is just a small selection from among the many new products we have developed. Other manufacturers have also brought some interesting new products onto the market this year. More about this can be found in our blog as well as in our Facebook page.

The Christmas season is traditionally a time of reflection on what really matters in life – for example helping other people. So this year we are making a donation of 10,000 € to the ‘Mercy Ships’ , relief organisation, who operate the world’s largest private hospital ship which is used to carry out operations in the world’s poorest countries.

We wish you a host of clear nights under the stars and a Merry Christmas with family and friends. We would like to thank you for your confidence in us and look forward with you to a happy and astronomically successful year in 2018!


Good value set offer: Meade N 150/750 LX70 telescope

December 19 2017, Stefan Taube

The telescopes in the LX70 series by Meade have proven over many years to be good models for beginners. The basic set offered by Meade includes telescopes without motors and without pole finders.

So, we have put together a set that contains all these accessories: The Meade N 150/750 LX70 telescope set for only €699.00.

You save €279.00  compared with if you had bought all the items individually!


For this set, we opted for the Newton telescope with a 150-millimetre aperture, because we think that these optics make the ideal combination with this mount.

The LX70 telescope with Maksutov optics is over the budget of many beginners. The refractor has a very deep eyepiece for the LX70 mount. The Newton telescope with a 200-millimetre aperture  is a little heavy for the LX70 and has a relatively large leverage effect.

The N 150/750 LX70 telescope, however, is a well-matched system at a decent price! You can very easily use a camera for photographing the moon and the planets on this system. We are pleased to be able to offer the telescope as an entire package with really useful accessories at a very good price at the moment!

Sale: Beginner Telescope Bresser Messier-130 EXOS-1

December 12 2017, Stefan Taube

The Newton Telescope N 130/1000 Messier EXOS-1 von Bresser is an excellent beginners scope.  The primary mirror at 130 mm diameter allows for observations of brighter deep-sky objects, like the binary star Albireo in the constellation Cygnus, the “double-double” Epsilon Lyrae in the constellation Lyra or the famous Orion Nebula in the constellation with the same name.

Observing the Moon and planets is quite enjoyable  with the Newton, since it does not show any color distortions as a result of its build.

Bresser Messier N130

A tried and tested beginner telescope: N 130/1000 Messier EXOS-1

In combination with the EXOS-1 Mount, you can focus on an object and follow the rotation of the heavens by turning the flexible shaft.  You can even motorize the mount, as well as use a polar finder, to make using the scope a breeze and more exact.

We offer the entire set, comprised of the telescope and mount with tripod, currently for the price of only 298 Euros.  That means you save 131 Euros off of the recommended price.

Mit der EXOS-1 Montierung können Sie das Teleskop auf das gewünschte Objekt ausrichten und über Drehung an der biegsamen Welle der Himmelsrotation nachführen. Es ist auch jederzeit eine nachträgliche Motorisierung möglich, sowie die Verwendung eines Polsuchers, um dieses Nachführen bequemer und genauer zu ermöglichen!

The set is delivered with a 26mm Super Plössl eyepiece.  Three other eyepieces are also available at special price:

That way you can get your telescope with a fitting set of eyepieces! The offer for the telescope and eyepieces is valid until the 31st December 2017 and only while supplies last.


New: Pro camera by ZWO and more accessories for astrophotographers

December 8 2017, Stefan Taube

We would like to present to you a small selection of items that we included in the range recently:

  1. ZWO camera ASI 1600 MM Pro Mono

The ASI 1600 series is the favourite model range by ZWOptical. The ASI 1600 cameras have a relatively large sensor and a small pixel size. There are, therefore, models without cooling that are used mainly by planet photographers and DeepSky cameras that can be used by anyone. We offer the cooled models in a set with special filters and a filter wheel.

The spearhead of this model range is the new ASI 1600 MM Pro Mono. It is ideal for astrophotographers who want to capture faint nebulae with exposures lasting for hours. The incorporated 256 MB of buffer memory provides loss-free transfer even with USB 2.0.


  1. Orion camera StarShoot AutoGuider Pro Set

If you want to take exposures of several minutes, you should think about tracking control. With this procedure called autoguiding, the mount must run in a controlled fashion because the camera mount must always be exactly oriented towards the desired area of the sky for the shot to be successful. A separate camera is mostly used with its own optics for autoguiding. The camera continually follows a star and gives control impulses to the mount if the star moves.

Thanks to sensitive camera sensors with a high resolution, these autoguiders can be made to be compact. A very well-made example is the new set from the camera StarShoot AutoGuider Pro Mono and the Ultra-Mini Guidescope by Orion.


  1. Baader MPCC V-1 Mark III Newton coma corrector set 2”

Newton telescopes are very popular with amateur astronomers because they cost relatively little money and can gather a large amount of light. As with any optical design, Newton telescopes suffer from image aberrations. On the edge of the field of view, the stars are exploded forming a “comet”. What are referred to as coma aberrations are particularly noticeable in astrophotography. The manufacturer Baader-Planetarium offers an excellent coma corrector that is also included in the set with the matching adapters: Baader MPCC V-1 Mark III Newton coma corrector The special feature of this coma corrector is that it does not increase the focal length of the optics. There is as much light as without the corrector, so that the exposure time does not have to be increased.


  1. Oklop padded bag for the Newton 150/750

About the Newton telescope: We now offer padded carrying bags by Oklop. They are made so a specific telescope fits perfectly and can be transported securely without taking up a lot of space.

We offer, for example, bags for the Newton telescope 150/750, Newton telescope 150/1000 or the Celestron telescope SC 1100. Other bags by Oklop can be found here.



Infographic: Astro-highlights in Winter 2017/18

December 7 2017, Marcus Schenk

The new cosmic calendar for the next three months at a glance!  Our astronomy infographic shows you all you need to keep an eye out for in the coming months.  Check out the text below for more details of each event!



08 Dec – Moon occults Regulus

At the beginning of December the waning Moon will occult the star Regulus in the constellation Leo.  It is a special event, since Regulus belongs to the brightest stars in the night sky at 1.3 mag.  A pair of binoculars or a small telescope will suffice, to witness it all.  However, you will need a good view of the north-eastern horizon.  Best case scenario would be finding a nice open area or a hill, from which to observe.  It is only important that no houses or forest obstruct your view.

13 Dec –  A Lunar Meeting with Mars

The narrow sickle of the waning Moon will show itself shortly before dawn, meeting up with Mars at about 6 degrees.  Yet there is more to see: with the star Spica, the two celestial bodies will create a triangle.  Closer to the horizon, you will also be able to see Jupiter.  It will appear, as if all four form an arrow pointing towards the horizon.

14 Dec – Geminids

If the night sky is clear, look to the south to see the Geminid meteor shower, originating from the constellation Gemini.  More precisely, the point of origination will be roughly two degrees above the star Pollux.  Between 9 PM and 6 AM is the best time for viewing the Geminids, with roughly 120 meteors per hour . making it one of the most active meteor showers.  Unfortunately, the full Moon will create some competition as it rises, but the event should nevertheless not be missed!

21 Dec – Winter Solstice

Every year on the 21st of 22nd of December, we get to experience the shortest day and longest night of the year.  This year on the 21st, Winter officially begins and the Sun will set early.  The night will last about 12 hours – a dream for every hobby astronomer, who wants to observe for long periods.

31 Dec – The Lunar Occultation of Aldebaran

In the night of the 30th to the 31st, the Moon will occult the star Aldebaran, which is the most prominent star of the Taurus and belongs to the brightest stars in our night sky.  Such an occultation of a bright star is quite an experience.  Almost completely full, the Moon will approach Aldebaran on its dark and interesting side.  The star will disappear sometime around 2 AM and reappear around 30 minutes later on the opposite side.

01 Jan – Mercury at Its Greatest Western Elongation

Mercury orbits so fast and so close to the Sun, that we cannot see it all the time.  Yet, today the planet will be at a distance of 22 degrees from the Sun.  During dawn, Mercury will appear around 6:30 AM in the south-eastern sky.  As the sky brightens, however, you will quickly lose sight of the planet.  Luckily, Mercury is quite bright, so you will be able to see it at even 7:30 AM.  In case it is overcast or you are sleeping off ringing in the New Year, you will still be able to see Mercury until the 10th of January.

03 Jan – Quadrantids

The next meteor show is already upon us: the Quadrantids.  This meteor show will originate from the constellation Boötes and will rain down a maximum of 120 meteors per hour.  You will have the best seats for the show if you happen to be out from the 2nd to the 3rd of January.

07 Jan – Mars Meets Jupiter

On the morning of the 7th, Mars and Jupitar will have tea and crumpets.  In the middle of the constellation Libra, both planets will be illuminated at a distance of 12 arc-minutes from one another, which is about a third of the Moon’s diameter.  You will be able to use your telescope to view both planets in one go!

11 Jan –  The Meeting of the Moon, Mars and Jupiter

A few days later in the same region, Mars and Jupiter will create some more space.  Yet, on this particular morning, the Moon plays a role.  The thin sickle will shine about 3 degrees above the two planets.  Even if you have to dress warm to see it, the sight will melt any ice in the vicinity.

13 Jan – Mercury Meets Saturn

Mercury will give us one more chance, before exiting the stage.  Yet, this morning, the fastest planet will be visible with the gas giant Saturn.  Shortly before sunrise, the two will appear just above the horizon in the south east.

31 Jan – Ceres in Opposition

Ceres is one of the most well known dwarf planets of the solar system with a diameter of 963 kilometers.  It orbits, with the asteroid belt between Mars and Jupiter, the Sun every 5 years.  On the 31st January, Ceres will come into opposition to the Sun and you can observe it at its greatest brightness.  With a bright 6.9 size class, it will move from the head of Leo between the constellations Lynx and Cancer.  You can use a telescope or a large set of binoculars to find dwarf planet.  More exact details can be found here:

01 Feb – The Moon Meets Regulus and Mars meets Acrab

If you like to observe during the morning hours, then there is something for you on the 1st of February.  At about 4 AM, the pinzers of Skorpio will rise in the south east.  Yet, there is more: Mars.  The red planet will push past the star Acrab at a distance of around 18″.

Moreover, the following evening, the Moon will be about 7 arc-minutes away from Regulus, the most prominent star of the constellation Leo.  The time for the meeting is quite good: around 7 PM, European Central Time, the Moon will be closest.

08 Feb – The Moon Occults γ Lib

This occultation may not be observed by so many star gazers, since it will take place in dawn, when most are still laying in a warm bed.  That makes the occultation of the star γ Lib by the Moon, within the constellation Libra, quite a seldom seen event.  The Moon will be illuminated at around 45% and be edging ever closer to the star with its bright side.  Around 4:20 AM, the star will disappear behind the Moon and reappear at around 5:30 AM on the un-illuminated side of the Moon.

11 Feb – A Lunar Meeting with Saturn

The Moon seems to enjoy visiting our planets.  On the 11th of February, our satellite will meet with Saturn.  Such meetings are always an amazing sight and a great opportunity for a great photo with a standing camera and lens.  The Moon will be visible about 3.5 degrees higher in the sky, and as a result easier to spot.  Around 5 AM, Saturn will peer over the horizon.  It is not really the best time for the ringed planet however, as it will only appear in the second half of the night for next few months.  As early Summer sets upon us, the planet will appear at more comfortable times.  In June, it will even stand in opposition.

21 Feb – The Moon Occults μ Cet

An occultation at dusk: around 6:20 PM, the Moon will occult the star μ Cet in the constellation Cetus.  After a good hour, at around 7:15, the star will reappear on the other side.  This time the Moon will approach the star with its un-illuminated side.  During observation, you will notice the star disappear so suddenly, as if someone just pinched its flame like that of a candle.

23 Feb – The Moon Occults Aldebaran

A highlight on this day is the lunar occultation of Aldebaran.  As in last December, you should not miss this event, because such occultations are quite seldom and this will be the last occultation of Aldebaran for years to come.

The Moon will inch towards the star with its un-illuminated side.  For many, it is quite a surprise when the star suddenly disappears, despite it being expected.  At around 5:50 PM, Aldebaran will disappear and at 6:50 PM reappear.  For amateurs, it will be interesting to following the occultation to the minute.  With a Touptek Camera and software from SharpCap 2.7 will both be helpful in such a scenario.

Enjoy stargazing and clear skies from the team at Astroshop.

Improved version of the CL Companion by Swarovski Optik

December 1 2017, Stefan Rieger

Swarovski Optik has revised the CL Companion. The ergonomics in particular have been improved.

The eyepiece cup has been enlarged and, therefore, fits better on the eye. This means that the eye is automatically guided to the image. Handling was improved further by moving the connecting bridge upwards towards the eyepiece. This means that the hand can hold the binoculars better. The focus button is easier to reach. The dioptre compensation has now been integrated into the central wheel. This reduces the risk of unintentional adjustment. The weight has also been reduced further. Compared to its predecessor, the 10×30 has been made 15 grams lighter.

The revised CL now uses the FieldPro carry strap connector. The risk of the carry strap getting twisted has now been considerably reduced. The CL companion now comes in anthracite or green and as a 8×30 or 10×30 version.

Swarovski has recognised the trend towards customisation and now offers a series of binoculars with three different bags and carry straps. The classic dark green bag with black carry strap bears the wording “WILD NATURE”.

For those who want something a little more modern, chose the binoculars in connection with the “URBAN JUNGLE” accessory pack, a light green bag with a grey carry strap.

The “NORTHERN LIGHTS” set has been designed for the tradition conscious. You will receive a grey felt bag with black leather appliqués and a grey felt carry strap.

All versions can be delivered from mid-November. The best thing to do is order your favourite combination now!
