Reduced prices for the Meade LX200

September 23 2022, Jan Ströher

The systems most widely used by experienced amateur astronomers include the LX200 series of telescopes from Meade. There are good reasons for this: the LX200 series combines coma-free ACF optics with a stable fork mount and modern electronics. The telescope is so compact that the smaller models are ideal for mobile astronomy and the larger instruments suit relatively small garden or club observatories.

Meade ACF-SC 254/2500 UHTC LX200

In addition to the advantages of the telescopes themselves, the LX200 series offers other useful features: the primary mirror lock prevents image shift and holds focus during long exposure times. The high-quality worm gear on both axes ensures smooth running at all speeds. Thanks to SmartDrive, the periodic worm error is permanently corrected (PPEC).

You have the universe at your fingertips with the AutoStar II control. This GoTo system will take you to over 140,000 objects! Of course, the LX200 telescopes can also be controlled from an external computer using third-party software.

We currently offer a selection of LX200 models at reduced prices – namely the 8″ and 10″ versions, with or without a tripod. Here’s an overview of the discounted products:

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).

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.

Special offer: Omegon Basic telescopes at a special price

September 8 2022, Marcus Schenk

If you are choosing your first telescope, then take advantage of our summer astronomy sale. For a limited time, and only during September, we are offering Omegon entry-level telescopes at discounted prices. Taking your first steps in the world of the stars has never been more fun.

Have you ever taken a look at the major planets Saturn and Jupiter? No? Then now is definitely time. With Omegon entry-level telescopes, you can see these distant worlds with your own eyes – and not just as faraway specks. Anyone who discovers Saturn and its orbiting rings for the first time will find the starry sky totally irresistible!

Omegon Basic: closer to the stars

The Omegon Basic series is for everyone! For children, adolescents and adults alike. These telescopes are easy to operate thanks to their equatorial mounts. With the integrated fine adjustment shafts you can follow a celestial object wherever it goes and you can – if you want – marvel at it for hours. Best of all: once you have aligned your telescope with the Pole Star, you can track a star or planet using just one axis.

So which one will it be?

The telescope’s aperture is the diameter of the primary lens or the mirror that collects the light. The larger the aperture, the more light the telescope can collect. This dimension is more important than the focal length.

Choose your favourite from the Omegon Basic range of telescopes:

  • With the Omegon Basic AC 70/900 EQ-1 you can take your first look at the Moon and the major planets.
  • The Omegon Basic AC 90/1000 EQ-2 opens up the world of the Moon and planets. This stable entry-level telescope is our top suggestion for the whole family, because even children will quickly learn how to use it.
  • The first steps along the road towards a well-priced mirror telescope is via the Omegon 114/900 EQ-1
  • With the 126/920 EQ-3 and the 130/920 EQ-2, you can get even closer to the stars because, besides the Moon and planets, you can successfully observe bright nebulae.
  • From an aperture of 150mm – with the Omegon Basic 150/750 EQ-3 and Basic 150/750 EQ-4 – you open the door to many deep sky objects, such as nebulae and star clusters.

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.

New: Dobsonian telescopes from Celestron with StarSense technology

July 25 2022, Stefan Taube

With the StarSense Explorer series of telescopes from Celestron, it’s very easy to find objects in the night sky. All you need to do is install a free app and insert your smartphone into the special dock on the telescope.

Celestron combines classic Dobsonian telescopes with this new technology – a combination of proven and new technologies.

There are two models to choose from:

Both telescopes are complete systems with all the accessories you’ll need.

Celestron Dobson-Teleskop StarSense-Explorer

Celestron StarSense Explorer Dobsonian telescope

Unlike other PushTo technologies, no encoders are used. The StarSense app uses the smartphone’s camera to capture the current visible star field and compare it to an internal database. In this way, the app knows where the telescope is pointing, and can guide the observer to the desired object with arrows on the smartphone display.

Of course, the app also offers plenty of information about the celestial objects, together with suggestions for your observing night.

StarSense-Explorer-Technologie

StarSense Explorer technology

StarSense Explorer telescopes can also be used without the app, for example for a view of the Moon or another easily identifiable celestial object. For this purpose, a red dot finder is included.

Dobsonian telescopes are among the most popular entry-level telescopes. But they are also greatly valued by experienced astronomers for exploring the night sky without a camera. These telescopes’ minimalism makes them relatively inexpensive and are suitable both for beginners and advanced observers looking for an uncomplicated nature adventure. The StarSense Explorer series of Dobsonian telescopes combines this minimalism with a modern aid for navigating the night sky.

Affordable H-alpha solar telescopes from Lunt Solar Systems

June 29 2022, Stefan Taube

The most impressive way to observe the Sun is in H-alpha light. This is red light with a wavelength of 656 nanometres. With a normal solar filter, you will only be able to observe sunspots, whereas with H-alpha telescopes, prominences at the Sun’s edge become visible. Filaments, solar flares and much more can be seen on the solar surface. It is only in H-alpha light that are you able to appreciate the Sun’s dynamics.

Chromosphaere

Unfortunately, H-alpha filter systems often cost several thousand euro. However, the new LS40T Ha telescopes from Lunt Solar Systems make observing the Sun’s red chromosphere much more affordable: solar observation is accessible to everyone!

Lunt Solar Systems Sonnenteleskop ST 40/400 LS40T Ha B600

Lunt Solar Systems ST 40/400 LS40T Ha B600 solar telescope

LS40T Ha telescopes are available in three versions:

The difference between the versions lies in the size of the blocking filter. This filter element is located in the rear erecting lens, which looks like a star diagonal.

All blocking filters are suitable for visually observing the Sun. However, a larger filter is more suitable for photography, as it allows the exposure of a larger camera sensor. The B600 blocking filter is a very good compromise if you want to observe visually as well as photograph with an planetary camera.

The telescopes are supplied with a helical focuser, a Vixen standard prism rail, and a threaded connection for camera tripods. The practical solar finder helps to align the telescope.

An optional carrying case is also available, which makes use of the foam inserts in the original packaging. When you get your telescope, don’t throw away these inserts, instead use them to line the case. In this way, you replace the cardboard outer packaging with a beautiful and stable aluminium case.

Another important recommendation is the very practical sun hat from Lunt Solar Systems – not just for solar observing.

Dobsonian telescopes with special Bresser enhancements

June 28 2022, Stefan Taube

52181_1

Messier-series telescope with add-on sun filter

Bresser’s Messier-series Dobsonian telescopes  stand out from the crowd due to their features, which cannot be found on other brands of comparable telescopes:

  • The telescope tube is held in place using tube clamps. This means the tube can be rotated along its axis to find the perfect eyepiece position. It can be optimally balanced by adjusting the tube within the tube clamps. You can also fully demount the tube and use it with an equatorial mount, for example.
  • The altitude bearings have a comparatively large radius. This facilitates finer adjustments along the vertical axis. Many Dobsonian telescopes in this price range do not have proper altitude bearings!

    52181_3

    The altitude bearings with tube clamps glide along the rockerbox.

  • The so-called rockerbox, upon which the telescope is placed and which enables rotation in azimuth, is fitted with quick-release fasteners on the Messier Dobsonians, the kind you are familiar with from furniture. This enables the box to be quickly and simply assembled. In this way, the box can be disassembled again and again.
  • The Hexafoc focuser is superior to focusers on comparable telescopes by other manufacturers.
52181_2

The large Hexafoc focuser does not cast a shadow on wide-angle eyepieces.

  • A compatible solar filter is supplied with the product. As the tube is closed, no sunlight can enter the telescope from the side. This makes it possible to safely view the Sun.

In addition to these features, you also receive a Messier Dobsonian with high-quality optics and a parabolic mirror which is fully adjustable. This makes it possible to start a lasting relationship with the night sky. The Messier Dobsonians are available in two sizes. You can find both models here in our shop.

52181_5

The optics are fully adjustable.

Note: These telescopes are named after Charles Messier (1730-1817), whose “Catalogue of Nebular Objects” contains a number of celestial objects which you can observe using these telescopes. A modern guide to Charles Messier’s objects can be found in Cambridge University Press’ book The Messier Objects.
