The remote-controlled eagle – PrimaLuceLab Eagle

September 5 2023, Bengt Lindqvist

A comprehensive, intuitive to use WiFi and remote-control unit, no matter where, how, or what you need to control. No other system offers such a wide range of configurations, regardless of whether it is for controlling a camera, focuser motor, automatic flatfield box, or even the rotator. Operate two imaging devices simultaneously? It’s happy to help. Various connection options are available depending on the Eagle model you choose. The entire power supply runs via the Eagle and can therefore also be controlled and regulated. Tilt angle and motion sensor, absolutely no problem. From the Eagle 5 version onwards, these functions are fully available to you, not to mention the Eye sensor, which permanently measures the quality of the sky in the direction that your telescope is pointing. Windows or IOS – sure thing! N.I.N.A. or SharpCap, but of course! Put simply: if your preferred software is Windows-compatible, then the Eagle also supports it, without restrictions. It’s an open platform for the end customer.

Special features of the Eagle LE

You’re not keen on a Sesto Senso 2 motor focuser, and would rather work with a device of your own choosing? Happy to oblige. You will be able to connect it to the Eagle. In addition, you can use any software you choose. There are no limits here. We’ve all been there before. The camera freezes and will not deliver an image, what now? Pull out the plug? But let’s do that digitally. You can switch the Eagle and/or USB ports on or off remotely which can be tremendously helpful in tricky situations.

Even CPU-intensive image processing can be carried out on the fly thanks to powerful processors and a large memory, piggybacked on the imaging device of course! A full-feature, controllable Windows computer that leaves nothing to be desired, apart from the external power supply. 12 volts are required (max. 16 amperes), no matter whether power supply, power bank, or battery, and probably also the only downside. GPS, inclinometer, or even a humidity sensor; for the correct choices, depending on your requirements and setup, the following function and overview list should be a huge help. Should you still be unsure, our consultants will be happy to help you by telephone or e-mail.

Eagle series features

Key features depending on the Eagle model

  • WiFi – wireless connection
  • Ethernet – wired control
  • Remote On/Off – external access to turn the Eagle on and off
  • Remote On/Off USB – External access to turn the USB ports on and off
  • GPS sensor – location detection
  • Eye sensor – to monitor sky quality
  • Inclinometer

Infographic: Astronomy Highlights of Autumn 2023

August 31 2023, Marcus Schenk

Discover exciting celestial events in autumn 2023. Here are the highlights that are worth observing.

There are some really thrilling celestial events awaiting us in autumn 2023 that we really should not miss. From the best morning visibility of the planet Mercury, to a partial lunar eclipse, to the occultation of gleaming Venus by our Moon. Once again, the next three months have plenty of excitement in store. This infographic shows you all the highlights of the coming months of September, October, and November, and the text below the graphic gives you more details. I wish you lots of observing fun.



01/09 The Aurigids

During the night of 1 September, hobby astronomers can observe a special celestial event in the night sky: the Aurigids. This is an impressive meteor shower that appears to originate from the constellation of Auriga. The Aurigids are known for their bright and fast meteors, which travel at up to 65 kilometres per second. It is worth for us all to get up early or stay awake late, so no one misses this impressive event in the night sky!


04/09 Conjunction of the Moon and Jupiter

We are presented with another highlight on 4 September: the Moon and the gas giant Jupiter meet in the night sky. These two celestial bodies appear above the eastern horizon in the late evening. They climb higher over the course of the night, and will remain until the morning hours, eventually fading in the splendour of the new morning.


05/09 The Moon at the Golden Gate of the Ecliptic 

On 5 September the Moon crosses the Golden Gate of the Ecliptic. This phenomenon is a must-see for all celestial observers and offers a wonderful opportunity for observing with the naked eye.

The Golden Gate is neither an object nor a celestial event in itself, but an asterism in the constellation of Taurus. Its luminous pillars are formed by the open clusters Hyades and Pleiades.

The ecliptic, the apparent path of the Sun, runs along this gateway, through which our Moon and the planets appear to pass.


18/09 Venus at its brightest

Venus is at its brightest on 18 September. The evening star shines especially bright with a magnitude of -4.7, and can be seen to the east in the early morning hours. Venus appears almost like a spotlight because it is so bright, and we can still see it in the sky for some time – even as dawn begins to break.


19/09 Neptune at opposition

Neptune is at opposition to the Sun on 19 September, making it visible all night long. Hobby astronomers can observe the gas planet with a telescope, it appears small but intense in colour.


22/09 Mercury visible in the morning

Keep an eye out if you are an early riser! Mercury offers the best morning visibility of the year on 22 September. Back in January, the planet was hard to observe in the morning, but now we have a better chance. Shortly before sunrise, at around 05:50 CEST, the small planet is easily visible in the east, just above the horizon. Mercury is located in the constellation of Leo, so starting from the star Regulus, you can orient yourself around 10 degrees in a north-east direction.


26/09 Conjunction of the Moon and Saturn

The Moon joins the ringed planet Saturn on the evening of 26 September. This meeting offers a picturesque sight, and a highlight for all celestial observers.




1/10 Conjunction of the Moon and Jupiter

The paths of the Moon and Jupiter intersect once again. On 1 October we can marvel at this impressive event in the evening sky.


9/10 The Draconids

The Draconids shooting stars reach their peak on 9 October. This meteor shower originates from the constellation of Draco, which is located in a northerly direction above the Big Dipper. The number of shooting stars often varies from year to year. So, it is worth keep an eye out for them on different days at different times.


10/10 Conjunction of the Moon and Venus

Four days before the new Moon we can admire Venus and our Moon together in the morning sky. The two celestial bodies shine with a wonderful lustre above and below the star Regulus in Leo. An almost magical sight for every stargazer.


22/10 The Orionids

Meteor showers are lovely events for every avid star-gazer, the Orionids are no exception. They peak on 22 October and promise around 25 to 30 meteors per hour. However, the number of shooting stars often varies from year to year. To catch the best view of them, set your alarm clock and take a look outside in the early hours of the morning. A must for all shooting star fans.


24/10 Golden Handle on the Moon
On 24 October the Moon shows its most beautiful side: the Golden Handle is visible.

The flat light near the lunar terminator creates a breathtaking play of shadows and light. The Golden Handle is especially beautiful. For several hours, the peaks of Monte Jura are illuminated by the rays of the Sun, while the small Sinus Iridum valley is still in the shade. A veritable feast for the eyes that displays the Moon’s beauty in all its splendour.


28/10 Partial lunar eclipse

A special celestial event awaits us on the evening of 28 October: a partial lunar eclipse. The Moon moves into the Earth’s umbra at 21:35 CEST. However, the eclipse magnitude is quite low at only 12.7%. Nevertheless, the eclipse offers a beautiful, unmissable experience in the early evening. So, keep an eye out for this fascinating spectacle in the night sky!

More about the formation of lunar eclipses can be found in our magazine article “How does a lunar eclipse occur?”




03/11 Jupiter at opposition

Jupiter is at opposition to the Sun on 3 November. The gas giant is visible all night long and reveals itself in all its glory. This is a special event for all stargazers and hobby astronomers that you should not miss. Of course, you can also observe the gas giant in the coming weeks – not just today. But the planet appears much larger and it shines particularly brightly when it is at opposition. You can see the characteristic dark stripes on Jupiter’s surface with a telescope, along with its four largest moons: Io, Europa, Ganymede, and Callisto.


09/11 The Moon occults Venus

A special event awaits us on the morning of 9 November at 10:55 CEST: an occultation of Venus by the Moon. This is a very rare and impressive spectacle that is definitely not to be missed. It is the astronomical highlight of 2023 for advanced hobby astronomers. In order to observe this occultation, focus your telescope on the illuminated sickle Moon at around 10:50. The Moon will occult Venus from its bright side. The whole spectacle lasts around 80 minutes.


13/11 Uranus at opposition

Uranus is at opposition to the Sun on 13 November. The distant planet is visible all night so it is a great opportunity to observe it with your telescope. Despite its tiny size of 3.8 arcseconds, when you look for it with your telescope you will be able to distinguish it from a star because its surface looks wide and not point-shaped. In addition, its greenish colour is easily recognisable.


17/11 The Leonids

On the night from 16 to 17 November it is once again time – the Leonids reach their annual maximum and ensure a beautiful celestial event. Together with the Perseids, they are among the most well-known shooting stars that can be observed annually from Earth. There are even some years when the meteors fall from the sky in such abundance that it is almost like a rain shower. This spectacle is repeated every 33 years when the Earth comes into contact with the Leonids’ trail. But they will produce up to 20 meteors per hour even in normal years, which is an unmissable experience.


20/11 Conjunction of the Moon and Saturn

The Moon joins the ringed planet Saturn once again on the evening of 20 November. It is a fascinating sight that will accompany us in the evening sky.


25/11 Conjunction of the Moon and Jupiter

At the end of the month, on 25 November, we have another chance to marvel at an encounter between the Moon and Jupiter in the night sky.

New telecentric from Baader: TZ-4S Sundancer II

August 8 2023, Stefan Taube

Like a Barlow lens, a telecentric extends a telescope’s focal length. However, the telecentric generates a parallel optical beam. This is particularly important when using etalon filters for solar observation in H-alpha light.

The new Telecentric TZ-4S from Baader is perfect for use with the Sundancer II H-alpha filter. It replaces the integrated telecentric which has a 3x focal length extension. Thanks to the 4x focal length extension created by the TZ-4S, the ideal aperture ratio of f/30 is achieved, even with f/7 to f/8 optics.

The achromatic Telecentric TZ-4S is designed for the entire visible spectrum, and can therefore not only be used with H-alpha systems.

August promotion: iOptron CEM40 now at reduced prices

August 2 2023, Jan Ströher

CEM stands for centre-balanced equatorial mount, that is a mount supported at its centre of gravity, thanks to its design. This means that a lighter counterweight can be used, and it offers an excellent ratio of mount weight to carrying capacity: a CEM with a relatively low own weight can carry a comparatively heavy optic.

We are now offering the CEM40 series of mounts from iOptron at reduced prices for a limited time until 31 August!

The CEM40 mount weighs just 8.2 kilogrammes, but can carry optical instruments and accessories weighing up to 18 kilogrammes. This excellent payload/weight ratio of 2.5 is the reason why the CEM40 is so versatile. You can transport them to the best dark sky observation sites, or mount them on a small column in your garden observatory.

The following models in this series are available in August at a discount:

CEM40 GoTo with LiteRoc tripod and carrying case – 63903

Meade LX85 & LX200 on special offer

July 26 2023, Jan Ströher

From 15 July up to and including 31 August 2023, we are offering the following models in the LX85 and LX200 series from Meade at special summer-saver prices:

N 200/800 Astrograph LX85 GoTo for €2,799 instead of €3,299

This Newtonian is a compact, very fast device (f/4.0 focal ratio) for high-resolution astrophotography with short exposure times. It is especially suitable for large emission nebulae and galaxies. Despite the fast focal ratio and its optimisation for photographic purposes, it is also a pleasure to use for visual purposes – especially for deep sky objects! The large focuser with 1:10 fine adjustment ensures a bright image field and precise focusing. The secondary mirror struts are kept extra thin to cause as little obstruction in the light path as possible, which results in better contrast. With a generous 83.2 millimetre of back focus, there is enough working distance for other accessories, such as a coma corrector or filter wheel. Astrophotography with this fast focal ratio will definitely require a good coma corrector to obtain sharp and point-shaped stars across the entire field of view. A coma corrector may not be necessary for this Newtonian when combined with smaller camera sensors or for purely visual use.

The scope of delivery includes an 8×50 finderscope, a 35mm extension tube (important for visual use), a 26mm Super Plössl eyepiece, as well as a fan to ensure faster cooling for the primary mirror.

The LX85 mount is designed with mobile astrophotography in mind. With its powerful servo motors and Meade Smart Drive technology, it follows the rotation of the night sky and keeps the telescope aligned with the selected object for long exposure times – without the need for a meridian flip!

Meade LX85 Newtonian 200/800


ACF- SC 203/2032 UHTC LX85 GoTo for €3,669 instead of €4,580

With its Schmidt-Cassegrain design, this telescope leaves nothing to be desired: SC telescopes are suitable for all applications. No matter whether you want to observe planets, distant nebulae, or galaxies, whether purely visually or also for photography: anything is possible with a SC telescope!

The compact optics ensure low leverage stress on the mount and mean that the telescope is easy to transport. Focussing is carried out internally and is so adjustable that, even with astrophotography accessories attached, focusing is not a problem.

The LX85 mount is particularly lightweight and therefore ideal for mobile use either in the garden or at an observation location under particularly dark skies, and the GoTo AudioStar control helps you to correctly align the telescope and it automatically tracks your chosen observation object. This makes it ideal for beginners! The LX85 mount can be used with most commercially available telescopes up to 15kg in weight.

We have significantly reduced the prices of the following models from the  Meade LX200 series :

ACF-SC 305/3000 12″ UHTC LX200 GoTo without tripod for €6,399 instead of €7,999

ACF-SC 254/2500 10″ UHTC LX200 GoTo for €5,279 instead of €6,619

ACF-SC 305/3000 12″ UHTC LX200 GoTo for €7,679 instead of €9,589

Meade ACF-SC 203/2000 8″ UHTC LX200 GoTo telescope


ACF-SC 203/2000 8″ UHTC LX200 GoTo for €5,119 instead of €6,419

ACF-SC 203/2000 UHTC LX200 GoTo without tripod for €4,479 instead of €5,590

ACF-SC 254/2500 UHTC LX200 GoTo without tripod for €5,269 instead of €6,190

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

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).

All models covered by this summer sale are available from stock! This promotion is valid until 31 August 2023 only while stocks last!
