Astronomy Highlights in Winter 2022/2023

November 30 2022, Marcus Schenk

Mars at opposition, two planetary occultations by the Moon, the Geminids and beautiful triangular arrangements between the Moon and the planets. This winter, there are many reasons to look towards the stars. And you should join in!

In the “Astronomy Highlights in Winter 2022/23” infographic, you can find important celestial events for the next three months. Have fun observing!

December

02/12 Conjunction between the Moon and Jupiter

When darkness is upon us, we can gaze at the Moon and Jupiter on the south-eastern horizon. The gas giant will be blazing with an intensity of -2.5 magnitudes.

05/12 The Moon occults Uranus

The Moon and the planets travel along an imaginary line known as the ecliptic. This is the plane along which the planets and the Sun appear to move. Every now and then, the Moon occults one of the planets. And that time has come once again, as the dark side of the Moon approaches and occults Uranus at 5:34pm.

07/12 Conjunction between the Moon and Plejades

In the early hours of 7 December, the almost-full moon reaches the Golden Gate of the Ecliptic, which is flanked by the famous Hyades and Pleiades star clusters.

08/12 The Moon occults Mars/Opposition

Mars is at opposition to the Sun today and is  shining particularly bright and looks magnificent through a telescope. During this year’s opposition, the planet reaches a diameter of 17 arc seconds and a height of 66 degrees above the horizon from central Europe. And today is also a double event as, in the early hours of 8 December, at around 6am, our Moon occults the Red Planet.

14/12 Geminids

If the skies are clear in the evening, look towards the south. You will see the Geminids meteors emerging from the constellation of Gemini. Or more precisely, from a spot two degrees above the star, Pollux. With 120 meteors per hour, this shower is one of the events with the highest fall rates. In the early evening, up to 10pm, you can view it undisturbed by the Moon, as this is when our satellite appears over the horizon.

Lunar phases:

08/12 Full moon, 16/12 Waning quarter, 23/12 New moon, 30/12 Waxing quarter

January

01/01 Conjunction between the Moon and Uranus

Over and over, encounters or occultation between the Moon and planets take place along the path of the ecliptic. At the start of the new year, the Moon scrapes past Uranus at a distance of only half a degree.

03/01 Conjunction between Moon and Mars

Two bodies are competing for brightness today… the Moon and Mars. Both appear in the eastern skies when darkness falls. The Moon passes eastward beneath Mars.

03/01 Quadrantids

The next meteors are on their way to us – the Quadrantids. This meteor shower originates in the constellation of Bootes. The meteors shoot across the sky at a maximum rate of 120 per hour. The Moon only leaves our field of vision in the early hours of the morning.

16/01 Pallas at opposition

With a diameter of 588 kilometres, the asteroid Pallas is the second largest in the asteroid belt between Mars and Jupiter. During its opposition, it is so bright that we can easily see it with a small telescope and, theoretically, even with binoculars. To tell it apart from the stars, you should use a star chart whilst observing.

22/01 Conjunction between Saturn and Venus

A good view of the horizon is essential for this event. During twilight, the stunningly bright Venus outshines the considerably weaker, but still bright, Saturn above the western horizon. From 5:30pm, we have an hour-long opportunity to follow this celestial pair, both of which become weaker and then disappear into the haze.

23/01 The Moon near Venus and Saturn

An attractive event for all who are interested… Today a slim crescent moon joins the planets Venus and Saturn. Together, they are a dream team for a wonderful twilight photo.

30/01 Conjunction between the Moon and Mars

This evening, the Moon visits the Red Planet. During the night, our satellite draws nearer until both objects are around one degree apart in the morning hours.

Lunar phases:

07/01 Full moon, 15/01 Waning quarter, 21/01 New moon, 28/01 Waxing quarter

February

15/02 Conjunction between Venus and Neptune

Venus and Neptune come to within 0.25 degrees of each other – a very close encounter between two very different planets. Whilst Venus beams like a floodlight, Neptune shines 50,000 times less bright.

22/02 Conjunction between Venus and Jupiter

This evening, the crescent moon appears with two planets. A beautiful view which you should not miss.

27/02 Conjunction between the Moon and Mars

This evening, Mars and the Moon can both be found in the constellation Taurus.

Lunar phases:

05/02 Full moon, 13/02 Waning quarter, 20/02 New moon, 27/02 Waxing quarter

The PrimaLuceLab experience

November 24 2022, Jan Ströher

PrimaLuceLab, the Italian manufacturer from Porcia, specialises in high-end astronomy accessories. Products includes the high-quality PLUS range of prism rails, support rings and clamps, together with adapters, guiding systems, radio telescopes and a variety of products for holistic astrophotography solutions. PrimaLuceLab’s aspiration is to make astrophotography uncomplicated and accessible for all – this aspiration is fully realised with their specially developed PLAY software and their EAGLE, ECCO, ARCO, GIOTTO and SESTO SENSO series of products. The aim is to create a complete package that functions as simply as possible and makes the technology behind astrophotography as convenient for all users as it can be: a PrimaLuceLab experience, so to say.

PrimaLuceLab EAGLE control unit

When combined with the PLAY software, this system comprising various PrimaLuceLab products offers a complete set-up for all telescope models, regardless of brand. The PLAY software is very clear, user-friendly, offers an all-in-one solution with full ASCOM compatibility and works providing you use at least an ESATTO micro focuser or the SESTO SENSO 2. Instead of various software applications, you have everything combined in one clear and simple solution – indeed the name PLAY suggests the simplicity of the application – which allows even beginners to engage in astrophotography in an uncomplicated (yes, playful) and yet immediately successful manner. All other PrimaLuceLab products can be controlled using this software.

The ESATTO micro focuser

Functionality and technology are continuously tested and further developed by PrimaLuceLab. Products are always checked in the in-house workshop before they are sent to the warehouse or prepared for shipment. I was able to see this for myself during a visit to the company in October 2022. There, the founder and president of PrimaLuceLab, Filippo Bradaschia, gave me a live demonstration of the PLAY software functionality using a complete set-up comprising a Sky Watcher AZ/EQ5 mount, a cooled QHY163 monochrome camera, PrimaLuceLab EAGLE/ARCO/SESTO SENSO products, together with a Sharpstar 80mm apochromatic refractor. I was impressed by the overview of the operation as well as the functionality! The software even replaces the mount’s hand-held control. Filippo Bradaschia compares this to buying an Apple©™product: PrimaLuceLab offers you a complete experience and ensures that the individual components are all compatible with one another: the PrimaLuceLab experience!

Back in stock: Baader FlipMirror II

November 9 2022, Stefan Taube

Multiple faces – multiple uses

Baader’s multi-purpose flip mirror is back in stock! In combination with its level camera connector, the FlipMirror II offers a third connector, ideal for accessories such as off-axis guiders or calibration lamps for spectrographs.

63172_1

 

The FlipMirror II can be permanently mounted on the telescope as its optical finish is comparable to that of a high-quality zenith mirror. The flip mirror can also be used for visual observation.

Why do you need a flip mirror?

Unfortunately, every telescope only has one connector on the eyepiece side despite there being a large range of accessories that you may want to connect: eyepieces, cameras, off-axis guiders, guiding eyepieces, spectrographs and many more. For astrophotography and spectroscopy, these components need to be mounted at the same time.

The FlipMirror II provides more opportunities for this than other flip mirrors and it also provides solid screw adaptors. This is why multiple thread adapters are included amongst the accessories.

Hold the stars in your hand – the new Vaonis Vespera!

October 18 2022, Elias Erdnüß

The impressive Vaonis Stellina arrived on the market 3 years ago. With its fully-automatic alignment, autofocus, live stacking and app-based controls, it more than deserves the title of smart telescope!

Now the Vaonis is upping the ante… The new Vespera is a miniature version of the tried and tested concept. With a weight of just 5kg, this new observing station is more compact and more mobile than its alternatives. The Vespera can be taken anywhere quickly and at the drop of a hat. As with the Stellina, alignment takes place automatically using plate solving. Select your desired object for observation from the singularity app – the telescope finds the target and starts imaging. Watch on your smartphone or tablet as the celestial object becomes clearer, more colourful and more contrast-rich, minute after minute, whilst the Vespera collects more and more light using live stacking.

The Vespera also provides even better value for money than its predecessor thanks to its reduced size! Yet its optics still meet the highest possible standards. The in-built 50/200 (f/4) quadruplet apochromat in combination with the modern Sony IMX462 sensor provide high-quality astronomical images. Share these with friends and family!

Telescopes from Bresser’s Messier range

September 19 2022, Stefan Taube

The manufacturer Bresser offers a rich variety of telescopes for hobby astronomers in their Messier range. Options range from economically-priced entry-level models through to telescopes which make all of your wishes come true.

Large selection of scopes and mounts:

Within the Messier range, you can find optical telescopes, Newtonian telescopes and compact Maksutov scopes. The latter are very good for travelling and are designed for planetary and lunar observations.

These telescopes are equipped with a rail to attach them to astronomical mounts. As these rails conform to the Vixen style, the telescopes can be used with almost every mount.
For the Messier range, Bresser has developed both the EXOS-1 and the EXOS-2 mounts. They are adapted for these scopes. The mounts can be purchased with or without a motor. If you want a reasonably-priced entry-level model, you can leave the motor out. You can always add one later. Motors are especially necessary for astrophotography. You can find upgrade sets here in our shop.

The EXOS-2 mount is also available with computerised controls (GoTo).

Bresser Teleskop AC 102/1000 Messier Hexafoc EXOS-2

Bresser AC 102/1000 EXOS-2 GoTo Messier telescope

Ideal for beginners: Dobsonian telescopes

Within the Messier range, Bresser also offers a range of Dobsonian telescopes. The larger models feature altitude bearings which provide high levels of stability in all positions. Thanks to the OTA brackets, the tubes on these Dobsonian telescopes can also be placed on other mounts.

Dobsonian telescopes are ideal for optical use and are very reasonably priced.

Bresser Dobson Teleskop N 254/1270 Messier Hexafoc

All telescopes come with a suitable solar filter which is placed on the front end of the telescope. This makes it possible to safely observe the Sun.

All telescopes from Bresser’s Messier range can be found  here in our shop.

Astronomy highlights in Autumn 2022

August 31 2022, Marcus Schenk

Autumn is on its way, and the evenings get dark earlier. For many, this marks the start of a great observing season. And it’s all there: Saturn is eye-catching as it shines in the night sky, Jupiter is at opposition and there will even be a partial eclipse of the Sun! What’s more, the Moon will occult Uranus. And that’s just the start!

In our “Astronomy Highlights in Autumn 2022” infographic, you’ll find many of the important celestial events at a glance. Information and further explanations of the events can be found in the accompanying text.

Have fun observing!

September

11/09 Conjunction between the Moon and Jupiter

The Moon and Jupiter rise almost together and we can admire them at around 9 p.m. above the eastern horizon.

14/09 The Moon occults Uranus

The Moon and the planets move along an imaginary line in the sky known as the ecliptic. This refers to the apparent path along which planets move around the Sun. Once in a while the Moon occults one of the planets. Now, on the 14th, it’s that time again: the Moon approaches with its illuminated side and occults Uranus at around 10 p.m.

16/09 Conjunction between the Moon and Mars

Shortly before midnight, the constellation Taurus climbs above the eastern horizon and will look particularly attractive today, because it also marks the meeting place of Mars and the Moon. Together with Aldebaran, Capella and the Pleiades, it makes a lovely sight.

16/09 Neptune at opposition

Our farthest planet is at opposition to the Sun tonight. Neptune is currently 4.3 billion kilometres away from us and shines with a magnitude of 7.8. Its light takes 4 hours to reach the Earth. We can even see Neptune with binoculars, though it cannot be distinguished from a star. It is only with a telescope that can we identify it as a planet with certainty. But it’s not so easy to find as Jupiter or Saturn. A star chart or app will help you.

26/09 Jupiter at opposition

An opposition is quite special: for this is when a planet is directly opposite the Sun and shines brightly all night long. Jupiter is currently at an altitude of 42 degrees above the horizon. This is considerably higher than in recent years, which greatly improves the quality of our observations.

Lunar phases:

03/09 First Quarter, 10/09 Full Moon, 17/09 Last Quarter, 25/09 New Moon

October

05/10 Conjunction between the Moon and Saturn

Tonight, the Moon passes below the ringed planet. On the Moon you can also observe the phenomenon known as the Golden Handle, an illuminated mountain at the Moon’s terminator.

08/10 Conjunction between the Moon and Jupiter

Time for a planetary evening! The Moon and Jupiter meet today in the constellation Capricorn. In September, Jupiter was at opposition to the Sun and is still an excellent object for any telescope. Tonight, we won’t be disturbed by a bright Moon.

11/10 Mercury in the morning

From 5 October, we can catch Mercury in the morning sky. The closest planet to the Sun is usually too close to it, which is why we rarely see it. October is the only time this year that it is visible in the night sky.

14/10 Conjunction between the Moon and Mars

From midnight, we get a taste of winter because then the constellations Auriga and Taurus appear above the horizon. In the middle of all this we can also see Mars and the Moon, which are particularly close to one another today. Can you see the red colour of our neighbouring planet?

21/10 Orionids

The Orionids are a small meteor shower producing around 20 meteors per hour. The radiant is located in the constellation Orion near the star Betelgeuse. Although you can observe the shooting stars throughout the month, they will be at their peak between 20 and 21 October. The best time to observe them is between 10 p.m. and 4 a.m.

24/10 Conjunction between the Moon and Mercury

Are you an early riser? Perfect, because this morning you can take a quick look at the slender crescent Moon and Mercury. For this you will need an elevated location or an unobstructed view towards the horizon. Then, just before sunrise from 6:50 a.m., you will discover the two celestial bodies.

25/10 Partial solar eclipse

The last partial eclipse that was visible to us was on 10 June 2021. A little more than a year later we can follow the next one. It starts at around 11a.m. on 25 October when the Moon moves in front of the Sun and obscures around 25% of it.

Important: use a solar filter when observing. Safe filters are available in our Astroshop.

Lunar phases: 09/10 Full Moon, 17/10 Last Quarter, 25/10 New Moon

November

01/11 Conjunction between the Moon and Saturn

The waxing crescent Moon and the planet Saturn are now to be found together in the constellation Capricorn.

04/11 Conjunction between the Moon and Jupiter

This evening, the waxing Moon meets the planet Jupiter, which was at opposition in September. Over the course of the night, the two celestial bodies approach at a distance of around 2 degrees.

09/11 Uranus at opposition

Uranus is one of the most distant gas giants. It appears only as a tiny, greenish disc in a telescope and we cannot make out any detail. However, you can still distinguish it as a planet. Find Uranus with a star chart or, easier still, with your telescope’s GoTo system. Then you can identify the planet using 150 to 200 times magnification.

11/11 Conjunction between the Moon and Mars

Tonight, the waning Moon finds itself close to the planet Mars. The Red Planet is between the Moon and Aldebaran, the brightest star in the constellation Taurus. An interesting task for today is to compare the intensity of the red colours of Mars, Aldebaran and Betelgeuse.

17/11 Leonids

From 16 to 17/11, the Leonids reach their peak. Together with the Perseids, they are among the most famous meteor showers. In some years these meteors fall like raindrops from the sky. This usually happens every 33 years when the Earth meets the Leonids’ debris cloud. In normal years, the peak does not exceed 20 meteors per hour. This year, you can observe them during the first half of the night, undisturbed by moonlight.

Lunar phases: 08/11 Full Moon, 16/11 Last Quarter, 23/11 New Moon, 30/11 First Quarter

Sky Quality Map of Europe: Where can dark night skies still be found?

August 9 2022, Stefan Taube

Following the success of the Sky Quality Map of Germany, Oculum Verlag has produced another pull-out map showing light pollution. The Sky Quality Map of Europe is a comprehensive source of information for anyone looking for dark skies in Europe.

Sky Quality Map

Additionally, the map can play an integral role in the public relations activities of observatories and also contribute towards the conservation of nature as light pollution is not only annoying for astronomers, but it is also a significant cause of insect death.

Satellite images were used to generate data which renowned Italian researchers Fabio Falchi and Riccardo Furgoni then processed.

This data was carefully calculated, taking numerous factors into account, to enable them to reach reliable scientific conclusions about artificial light in the night sky.

Sky Quality Map

A high-quality travel map was used as a cartographic basemap. Even small towns, bodies of water, train tracks, streets and attractions are listed on the map. This means the map can be used for planning as well as for navigation.
