Order the new version of the OCAL collimator now!

October 18 2023, Stefan Taube

The OCAL PRO collimator has revolutionised  precision collimation of reflector telescopes since its introduction in 2021! Now you can get an improved version of the collimator: OCAL V3.0 electronic collimator

Transportation and general usage can cause telescopes to lose their collimation. This is because the scopes’ primary and secondary mirrors shift position. The instrument can no longer show off its capabilities. An abundance of collimation accessories help to redress this.

The OCAL V3.0 uses a camera for this. This makes it unbeatably precise.

The OCAL V3.0 has an entirely new design:

  • Inside, it has an in-built, light-sensitive CMOS sensor. This makes collimation easier in poor light conditions.
  • Exposure time is also now only 1/20, compared to previous models.
  • The OCAL V3.0 has a much bigger lens than both of its predecessors.
  • The new OCAL V3.0 can achieve considerably higher resolutions. This makes images clearer, even in critical conditions and improves the precision of the results.
  • The new version comes with different adaptors.

You can find further information, price and purchase options using the following link: OCAL V3.0

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
  • Motion detector
  • DARK mode– disables all LEDs on the Eagle
  • Industrial grade SSD/RAM
  • ECCO2– optional module to control dew heater temperature For automatic real-time monitoring, over and above the standard Eagle functions, equipped with a humidity sensor and an air pressure sensor.

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

CEM40 GoTo LiteRoc – 62121

CEM40 GoTo with tripod – 61904

CEM40-EC GoTo high precision encoder with LiteRoc tripod – 62122

CEM40-EC GoTo high precision encoder with tripod – 61906

As always, this promotion is on a “first come, first served” basis and only as long as stocks last!

Promotion period: 01 to 31 August 2023.

Total lunar eclipse on 16th May 2022

April 25 2022, Marcus Schenk

After more than three years, we are once again about to enjoy a total lunar eclipse. It is a memorable experience when the full moon gradually disappears from the sky, smouldering with an unearthly rust-coloured glow.

This year, we are only able to view the first partial phase up until the start of the totality. You can find everything you need to know in the “Brief information about the total lunar eclipse” infographic.

We wish you a very happy lunar experience! With the naked eye, a telescope or binoculars.


Useful products for the lunar eclipse

Do you have a telescope and want to quickly and easily photograph the Moon? The Omegon Easy-Pic smartphone adapter is ideally suited to this. Simply attach it to the eyepiece and lock your smartphone in place –  and you’ll soon have a lasting memory of this unique experience.

Smartphoneadapter für die Mondfinsternis

Our infographic provides the most important information about the current lunar eclipse. When the Moon shines red in the sky, it shines several magnitudes less bright. Photographing it with a long enough focal length without a telescope can be a challenge – especially during totality. Is there a simple solution? Yes. The Omegon Mini Track. Although most often used for the Milky Way and deep sky astronomy, it is also an excellent tool here. Tracking provides sharp images of the red Moon.

Die MiniTrack nimmt auch eine Mondfinsternis auf

Of course, every telescope and every pair of handheld binoculars are suitable for observation. Take a look at our product pages – you can find a suitable device for every type of observation.

Like our infographic? You can share and print out our graphic, hang it in your observatory for visitors or create a link to it on your website (at: www.astroshop.eu).

Want to soak up some of the atmosphere? In this blog post, you can see images of the lunar eclipse created by our colleagues in 2018.

New version: the Polarie U star tracker mount from Vixen

October 28 2021, Stefan Taube

A few years ago, the Japanese manufacturer Vixen launched the Polarie, the first tracking unit for cameras that can fit in every photographer’s bag. The tracking device, also called a star tracker, compensates for the celestial rotation. With it, a camera remains aligned with a section of the night sky for many minutes, and can gather light from faint stars, the Milky Way and cosmic nebulae.

Vixen now offers a new version of its successful star tracker mount, the Polarie U Star Tracker.

Polarie U star tracker mount with camera and optional ball head

Compared to the classic Polarie, the new Polarie U is significantly lighter whilst at the same time having a higher load-bearing capacity. The distance between the two bearings supporting the rotating shaft is approximately four times that of its predecessor. This has led to a higher load-bearing capacity despite a 20% weight reduction. It can carry 2.5kg for wide-field astrophotography using lenses with a short focal length. The optional mounting accessories comprising a prism rail and counterweight can be used to increase the load capacity to 6.5kg, so that the star tracker mount can also carry cameras with large lenses.

In addition, the  Polarie U creates its own WLAN. You can connect your smartphone to the mount and control it using a free app. With a suitable cable release from the Polarie U accessory selection, you can also control the camera itself via the app, for example to set a series of exposures. This is not only convenient, but also very useful thanks to the hands-free operation.

The Polarie U can of course also be converted for use in the southern hemisphere. The lightweight mount is therefore ideal for your next expedition south of the equator.

Baader SunDancer II for observation and solar photography

October 7 2021, Stefan Taube

The Baader SunDancer II sun filter transforms smaller refractors quickly and simply into telescopes for solar observation using H-alpha spectral lines. In this wavelength, you can see the Sun’s chromosphere with dark filaments, bright radiation bursts and spectacular solar prominences!

Baader SunDancer II H-alpha 2″/1.25″ solar filter

Simply position the SunDancer II between the diagonal mirror and the eyepiece and connect it to a power source. The filter is then automatically brought to the optimal operating temperature so that no adjustments are required during longer observations.

The SunDancer II can be safely used on refracting telescopes with apertures up to 80 millimetres. An additional energy rejection filter is only required in front of the telescope for objective apertures upwards of 80 millimetres; alternatively, the telescope can be dimmed using an optional 80mm screen in front of the lens.

Telescopes with secondary mirrors, such as Newtonian, Maksutov or SCTs, always require an additional energy rejection filter, regardless of their size.

The complete solar disc can be seen in telescopes with apertures of up to 600mm.

The T2 thread beneath the eyepiece clamp facilitates easy adaptation for larger cameras:

New: Deluxe equatorial wedge for Omegon MiniTrack

August 27 2021, Marcus Schenk

Using the latest deluxe equatorial wedge, aligning the MiniTrack with the north celestial pole is easier than ever. The advantages? Spherical stars all night long.

How do you align your MiniTrack and other astrotrackers without an equatorial wedge? In theory, this is possible using a tripod head but the alignment and the fixed support sometimes resemble weather forecasting, in a word: uncertain. And yet, the photography session is meant to be a success.

The right tools for success

Thanks to the deluxe equatorial wedge, you can simply and precisely align your MiniTrack with the north celestial pole. It’s easy peasy lemon squeezy!
A robust locking mechanism provides permanent polar alignment, even when you are continuously focusing your camera on new targets.

In our set-up, we use an Omegon 32mm carbon tripod, the deluxe equatorial wedge and a MiniTrack 3 with pole finder.

Simple installation on any tripod

Using the 3/8 inch thread, you can attach the polar wedge to any camera tripod. To do so, you simply need a mini Vixen-style rail, such as the Omegon 55mm prism rail, which can be used with the MiniTrack. You can then connect and align your astrotracker easily.

Quality made in Portugal

The equatorial wedge is manufactured to the highest quality and consists of CNC components and stainless-steel screws. It is produced in small batches in Portugal and checked for quality.

The ideal addition to your MiniTrack: view the Omegon Deluxe equatorial wedge in the shop now.
