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.

Omegon Advanced 150mm: now with 2″ focuser
June 16 2021, Marcus Schenk
The Omegon Advanced 150/750 EQ-320 telescope is a popular instrument offering an introduction to the exciting hobby of astronomy. With a new, large focuser, you can now even use 2″ eyepieces. For stunning observing and almost limitless views of the cosmos.
Until now, observers using the Advanced 150/750 EQ-320 have only been able to use 1.25” eyepieces and accessories, but with the new 2″ Crayford focuser (patent pending), you will literally grow your horizons. This gives you the freedom to choose the eyepieces and accessories you want to use.
These are advantages the focuser offers:
With the 2″ eyepieces available in our shop, you can reach a larger area of the sky than is possible with 1.25″ eyepieces. For example, you can capture full-size large nebulae or enjoy seemingly never-ending vast fields full of stars. It also makes it easier for you to find objects. In short, a 2″ focuser is a blessing for deep-sky observers who want to experience the skies as if through a panorama window.
What if you complement the standard 1.25″ eyepiece, as supplied, with a 2″ eyepiece? The Omegon SWA 32mm 2″ eyepiece offers a fantastic image and a real wow-effect for deep sky observing.
Smooth mechanics for precise focusing
Such large focusers are quite unusual for a 150mm Newtonian telescope. However, our development department wanted to ensure that even owners of medium and compact telescopes could benefit from wide-angle eyepieces. In contrast to a normal geared focuser, the new 2″ Crayford focuser with ball bearings runs totally free of play. This allows you to focus your object smoothly and with high precision.
The advantages of the Advanced 150/750 EQ-320:
- Experience sharp and clear objects: with the parabolic primary mirror
- 2″ Crayford focuser (patent pending) for 1.25″ and 2″ eyepieces: you can connect additional accessories at any time – even from other manufacturers
- Equatorial mount: so that you can precisely track celestial objects
- Trouble-free start in the sky: complete telescope with two eyepieces
- Find objects easily and successfully with an illuminated LED finder
- Immediately recognise stars, planets and nebulae – even if you’re an absolute beginner
The Advanced 150/750 EQ-320 telescope is available with immediate effect with a 2″ focuser.
New: Diamond Steeltrack focuser with Steeldrive from Baader
June 17 2019, Stefan Taube
Diamonds really are astronomers’ best friends – at least since the Baader Diamond Steeltrack focuser has been available. It uses real diamonds in its drive system!
In contrast to conventional Crayford or rack-and-pinion focusers, the Diamond Steeltrack’s micronized drive system guarantees entirely backlash-free operation, is completely non-slip and torsion-free – and has a vertical load capacity of 6 kilograms!

The Steeldrive II motorized focuser drive permits automated focusing of a telescope via computer, as well as precise and vibration-free focusing using the buttons on the hand-held controller.
A good focuser considerably enhances observing pleasure and is essential for high-end astrophotography. The Steeltrack focuser is currently the best possible solution available!
Focusers: This is how you optimise your telescope on the accessories side
June 19 2017, Marcus Schenk
A focuser is most likely the component, that is used most frequently and intensively on a telescope. How often do you plug in eyepieces, adapters and cameras? Yes, a focuser has to cope with quite a lot. But is it of sufficient quality? Many telescopes are designed for a very reasonable price – this can then be noticed on the focuser. Optimising the focuser has a tremendous effect at this point.
Having a good look at your current focuser quickly reveals whether you can achieve even better results with your telescope.
An interesting question: What is the purpose of a high-quality, accurately moving focuser? What should it be able to do?
Five arguments for a good focuser
A focuser should
… be free of play.
You probably know this? You turn the focuser wheel, but the mechanical system rotates without any effect. And all of a sudden, it starts to move. On the one hand this is annoying, on the other hand it gives you the feeling of working with low-quality material.
…be free of any shifting.
You turn the focuser wheel, but Jupiter performs a rain dance and is jumping about in the eyepiece. Even worse in a camera. The object may even jump out of the field of view. Diagnosis: Shifting. This should be remedied as quickly as possible by using a good focuser.
…not bend when a camera is connected.
Unstable focusers sometimes lead to fatal results for your astro photographs. If the focuser tube bends, a photo may be sharp in one corner, but blurred in the other. Now, who wants such a result after an otherwise successful photo session. Further down, you find a list with a load capacity that specifies the maximum camera load, which should help to avoid such problems.
…have an accurate, fine focus adjustment.
Anyone enthusiastic about astro photography knows: Focusing the camera on an object in the sky is a challenge. This is much easier with a smooth running focuser or a 1:10 dual reduction. This allows you to adjust the focus in the range of tenths of a millimetre. This all to find the exact sharpness.
…not slip when using heavy accessories.
A heavy eyepiece may have a weight of up to 1 kg, camera equipment may even be heavier. In this case, it is an advantage to have a focuser that does not slip under a heavy weight.
Our product range includes some Omegon focusers, with which you can easily optimise your telescope and enhance its performance. For even more fun when star gazing. Especially the Omegon products of the series V-Power, Omegon Pro and the Omegon Hybrid Caryford Dual Speed are dedicated for these five wishes and fulfil them with high precision. The mentioned Omegon Hybrid Caryford Dual Speed has even been designed with a very low construction height. On very fast Newton systems, with e.g. f/5, one can reduce the vignetting and enhance the illumination.
You surely want to know whether the focuser matches your telescope. How high is the backfocus? What are the adapter measurements? How high is the load capacity of the focuser? This new list provides all information at a glance. You can immediately see, which focuser would suit you best.
Omegon V-Power: toughened focusers for better astro photos
November 28 2016, Marcus Schenk
Taking astro photos means facing many challenges. One of these are sharp astro photos. It is not easy to focus on weakly glowing stars and nebulae during the night. A perfectly tracked astro photo, but blurred? Inconceivable!
However, the perfect solution for this is now available: the new Omegon V-Power focusers. Making sure that your astro photo does not end up in drama, but as a story with a happy end.
What makes the V-Power focusers so distinct?
Important parts of the V-Power focuser are made of stainless steel instead of soft aluminium. Robust V2A ball bearings and stainless steel rings ensure high precision focusing. A dual speed 1:10 reduction provides the basis for a sensitively focusedastro photo, and the laser engraving allows you to return to previous settings very quickly. And if you have planned the future use of a motorized control, this is also possible.
With the V-Power finder base you can now also connect your finder scope. Simply attach the base to the focuser – and you are ready to go!
With these sets you can simply connect the focuser to your telescope
The V-Power series is available in different versions: for Newton and Schmidt-Cassegrain telescopes. A plug & play solution is available in a set with matching adapters. Easy focusing in just a few steps.
