10×42 EclipSmart solar binoculars by Celestron

February 27 2023, Stefan Taube

In order to safely observe the Sun, you need certified special filters, which provide enough protection from its intensive radiation, including the high proportion of UV radiation. Such filters are available for various optical instruments and are placed in front of the lens.

In the 10×42 EclipSmart, the manufacturer, Celestron, has created binoculars with this filter already pre-installed.

The benefits are clear and easy to see:

  • The ergonomic binoculars are always close at hand and can be kept in your car, for example. They also fit easily in your luggage when travelling to see the next solar eclipse.
    Solar observers can routinely follow developments in sunspots.
  • The 10×42 binoculars’ optics are powerful enough to be used for this purpose. Mounted on a tripod, the binoculars can reveal their full strengths.
  • The inbuilt filter cannot accidentally fall off and is protected against damage. This is not only important for solar observers, but also for outreach work carried out by observatories.

The 10×42 EclipSmart binoculars are exclusively designed for solar observations. This is why they are listed in the shop as a solar telescope.

New: CQ350 Skywatcher mount with high load capacity!

February 9 2023, Stefan Taube

In the CQ350, Skywatcher has created a heavy mount, which is still suitable for mobile astronomy. Thanks to its load capacity, it sits between the smaller EQ6-R and the larger EQ8-R.

The CQ350 is equally well suited for astrophotography in your own garden as it is for observatories; and thus represents an excellent compromise between mobile and stationary use.

77373_5

Summary of key features:

  • Load capacity up to 35 kilograms
  • State-of-the-art computer controls (GoTo) with SynScan V.5 hand control box
  • Integrated database containing 42,900 objects
  • Toothed belt drive for smooth operation without gear backlash
  • Dual dovetail clamp to accommodate all popular telescopes

This quietly operated mount is moved using belt drives with stepper motors in both axes (Encoder resolution: 55,193,600 counts/rev, 0.023 arcseconds). Its quiet operation and high slewing speed makes this mount even appeal to observatories with public guided tours.

New mount from Skywatcher: the AZ-GTiX WiFi

December 5 2022, Stefan Taube

Skywatcher is introducing a new mount from the AZ-GTi series. These altazimuth mounts feature:

  • Low weight and compact design
  • Motorisation with computer control (GoTo)
  • Integrated WLAN to connect to a smartphone or tablet

The new version, the AZ-GTiX WiFi, offers a higher load capacity and two saddle plates for mounting two instruments, for example a telescope and a camera, side-by-side.

77227_4

The AZ-GTiX mount can be used with any sufficiently-large camera tripod with a 3/8-inch photo thread. Skywatcher also offers the mount in a set with a tripod: AZ-GTiX WiFi with tripod.

The AZ-GTiX mount has a built-in WLAN module so you can control it wirelessly using a smartphone or tablet. All you need to do is install the free SynScan app for iOS or Android. Using its servo motors, the mount slews the telescope to any of the 10,000 celestial objects that you can select via the app.

All mounts in the AZ-GTi series can be found here in our shop.

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.

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.

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.

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 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.

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.
