Special gift ideas for astronomers and nature watchers

December 7 2020, Stefan Taube

Are you looking for a little something? We are offering you selected gifts for young and young at heart nature fans.

To help you make your choice, we have grouped our gift ideas as follows:

Our specific recommendations from these categories:

For astronomy beginners

Omegon-150-750

Omegon Telescope N 150/750 EQ-3

The Omegon Telescope N 150/750 EQ-3 is a very popular beginners telescope, with which the highlights of the night sky can be observed easily.  Star clusters, the Orion Nebula, the Andromeda Galaxy, the Moon and the planets are all within the capabilities of this beautiful instrument.

For amateur astronomers

Omegon ADC

Omegon ADC Atmospheric Dispersion Corrector

Advanced observers will love the Omegon ADC Atmospheric Dispersion Corrector. Behind this somewhat long-winded title, lies an accessory that allows planets and other objects, even those close to the horizon, to be observed in sharper focus. This is a particularly useful and reasonably-priced tool for planetary astrophotography.

For nature fans

Omegon Fernglas Talron

Omegon Binoculars Talron HD 8×42

Omegon Binoculars Talron HD 8×42  belong in every home.  Equipped with these you can take a quick look at birds in your garden, and you’ll want to take them with you when you next go for a walk or a hike. The binoculars offer a sharp image which, at eight times magnification, remains steady when hand-held.  They are easy to carry and, thanks to the large focus wheel, comfortable to use.

For children and the young

Omegon-70-700

Omegon Telescope AC 70/700 AZ-2

The Omegon Teleskop AC 70/700 AZ-2 is a classical refractor telescope, which is especially suited to children and the young. The low eyepiece position is easy for children to reach, and the operation of the telescope is particularly intuitive.  Due to the favourable focal ratio it is possible to view the Moon and bright planets without annoying colour aberrations. But you can also enjoy observing star clusters and the Orion Nebula using this telescope.

That special gift

Oklop Leinwanddruck Orionnebel M42

Oklop Orion Nebula M42 Canvas Print 50cm x 75cm

Talking of the Orion Nebula: this beautiful celestial object is also available as a high quality canvas print. You can find further images in this range of prints from Oklop here in our shop.

Experience astrophotography with the Radian Raptor

November 3 2020, Jan Ströher

Under its own brand, Radian, the American telescope retailer OPT is now launching a high-performance, top-quality, and super-portable apochromat with triplet lens design, which has already created a great deal of enthusiastic anticipation among astrophotographers. The Radian Raptor is a light and compact photo machine which, with an aperture ratio of f/4.5, will, above all, ensure amazing deep sky images. With a shorter design and weighing just 1.8kg, the telescope can be attached to photographic tripods and travel mounts such as the Skywatcher Star Adventurer or the iOptron SkyGuide without any problem. This makes it a perfect travel companion that can be easily transported in the padded backpack supplied and fits in any hand luggage.

OPT has thought of everything you might need for successful astrophotography in this triplet apochromat:

A fast aperture ratio of f/4.5 allows short exposure times, ensuring that the Radian Raptor stands out as a fast wide-field device – ideal for images of emission nebulae, galaxies and star clusters.

The use of premium glass, coupled with multi-coated surfaces, results in this triplet apo’s colour-true, high-contrast and very sharp imaging capabilities. An already built-in corrector flattens the entire field of view, shows needle-sharp stars right up to the edges and so makes the use of full-frame sensors a pleasure. In addition, there is no need to purchase an additional flattener or reducer.

With a focal length of just 275mm, you have an ultra-compact telescope for extensive wide-field images: objects such as the Veil Nebula or the Horsehead Nebula in the constellation Orion fit completely into the field of view of a full-frame sensor. Here is an image of the California Nebula captured by the 61mm Radian Raptor:

A solid, rotatable 2.5″ rack and pinion focuser with a high load capacity and the 1:10 fine focusing ensure a stable connection to your camera and precise focusing. The hexagonal tube clamps have differently-threaded holes to attach various accessories and integrated cable channels in the clamps reduce cable clutter. Especially for astrophotography, other equipment such as guidescopes, dew heaters, control modules or remote controls are usually required in addition to the telescope itself. The Radian Raptor is designed by astrophotographers and takes all possible applications into account. The recommended back focus of 55mm can be achieved and precisely adjusted with the adapters included.

Another treat is the inclusion of two bars for attaching to your mount: a 4″ Vixen dovetail bar and a 6.5″ universal Losmandy bar with a correspondingly-wider surface area. Both bars also have threads to attach the Raptor to a photo mount. With these you have compatibility with all mounts/dovetail clamps.

Finally, you get a waterproof and padded backpack to safely store the Radian Raptor, which also offers space for a CMOS camera and other small items.

Experience a new chapter in astrophotography and optimise your equipment with the Radian Raptor**!

New: StarSense Explorer telescopes from Celeston

June 30 2020, Stefan Taube

The idea of controlling a telescope with a smartphone is nothing new. With the StarSense Explorer range, Celestron brings  another option into play, which may be particularly interesting for beginners.

A special feature of the StarSense Explorer telescopes is that a WLAN connection does not need to be established between the telescope and the smartphone. The free StarSense Explorer app orients itself directly to the night sky, via the smartphone camera and a sophisticated mirror system.

Celestron StarSense Explorer DX

Celeston StarSense Explorer DX

 

Here’s how it works: All you need to do is install the free StarSense Explorer app and insert your smartphone into the special cradle attached to the telescope. The app uses location data from your smartphone to determine the observing location and does not require you to separately enter the current date and time.

The StarSense Explorer app uses a special lost-in-space algorithm (LISA), which is also used for the orientation of satellites. Star patterns recorded by the smartphone camera are compared with the internal database. These calculations are combined with information from the smartphone’s gyroscope and accelerometer. All this leads to a very high degree of precision that no other planetarium app can achieve! So you can move confidently through the night, even with no prior knowledge!

In drei Schritten zum Erfolg

Insert your smartphone, launch the app and you’re ready to start observing.

The StarSense Explorer app will suggest rewarding objects to observe that night at your location. You can also use the planetarium view to pan to interesting objects and identify them.

StarSense Explorer telescopes are supplied with an altazimuth mount so you can move the telescope simply about the altitude and azimuth axes. Two shafts with large grips allow fine adjustment and tracking. The telescopes are not equipped with a motor, but belong to the class of PushTo telescopes.

By the way, of course you can also use your StarSense Explorer telescope without a smartphone, for example, for a quick view of the Moon, which you should be able to find without an electronic helper.

Gran Turismo GT 81: the high-end telescope from William Optics!

April 9 2020, Stefan Taube

The Gran Turismo 81 refractor is a triplet apochromat with a lens unit with FPL-53 glass from Ohara, Japan. This combination ensures maximum colour purity and high contrast! The GT81 is therefore a versatile refracting telescope which satisfies every requirement!

William Optics GT 81 Astroshop

Apochromat refractor AP 81/478 Gran Turismo GT 81 from William Optics.

Equipped with an optional diagonal mirror, with this apochromat you can observe the Moon and the planets in high contrast. This fast telescope also enables sustained observing of more difficult deep sky objects: star clusters, galaxies and nebulae. Thanks to needle-sharp star images, resolving and observing globular clusters becomes a particular pleasure.

For astrophotography, we recommend the field flattener and focal length reducer (flattener/reducer) Flat6AIII. With this, the telescope delivers a flat field with the same focal position, even for full-frame cameras. The Bahtinov mask integrated into the telescope body helps with precise focusing.

Using the dovetail plate integrated into the frame, you can equip your Gran Turismo with a finder scope or guiding scope.

The very robust and stable GT81-Apo is ideally suited for mobile astronomy and astro-photography. The tube weight of four kilograms is easily accommodated by medium-sized mounts. Take this apo with you to a dark sky and discover the best objects from the Messier and NGC catalogues. The GT81 from William Optics will be, after the Firstlight, your new favourite telescope!

New Starfleet: The Omegon PRO Apochromats for Astrophotographers

November 19 2019, Marcus Schenk

These photos almost look like you were there. As if Captain Kirk was giving me a personal tour of the Pleiades on his command bridge screen on the Enterprise. However, what you see in the pictures below are images taken with the new Omegon PRO apochromats. And we swear, they were all taken from Earth 😉

So on to more beautiful photos.

Omegon’s new doublet, triplet and quadruplet refractors are a real compact Starfleet for astrophotographers who value brilliant and needle-sharp photos of the universe. The lens apertures range from 65mm to 107mm. There’s the right telescope for everybody.

Der Omegon Pro APO 60/330 OTA

The Omegon Pro APO 60/330 OTA.

Features include: Ohara FPL-53 glass for a true-colour image, CNC tube, hybrid rack and pinion focuser with, ball bearings and 360° rotation, tube clamps, dovetail bar, viewfinder shoe and Vixen-style dovetail bar.

The Andromeda Galaxy, APO 71/450 Quadruplet, Canon 6Da, 25×240 seconds, Image: Philipp Keltenich

And here is the fleet of telescopes at a glance:

  1. Apo 60/330 Doublet OTA #60852
    A small doublet apochromat for travel and for striking panoramic pictures.
  2. Apo 71/450 Quadruplet OTA #60855
    For fantastically beautiful, true-colour and flat images right up to the edges of the field of view. Here you don’t have to worry about how to attach a field flattener to your camera, because it’s already built-in. A great flat field apochromat!
  3. Apo 72/400 Doublet OTA #60853
    If you like to travel and love shooting large-area objects, you will love this refractor. A clear picture and only 400mm focal length, it captures the Andromeda Galaxy and similar objects.
  4. Apo 80/500 Triplet OTA #60856
    An apochromat with a clear and true-colour image, even at very high magnifications. The expertly-crafted 2.5″ focuser is larger than that of most 80mm telescopes. The advantage: so much illumination that even your full-frame camera will have fun with it. By the way, we also stock the carbon version of these apochromats: chic, thermally-stable and even lighter.
  5. Apo 90/600 Triplet OTA #60858
    Weighing just 5 kilograms but with a 90mm aperture: this apo refractor is suitable for your mount at home or for travelling under a dark sky. The 2.5″ focuser holds your camera in a stable position all night long.
  6. Apo 107/700 Triplet OTA #60859
    Sophisticated three-lens design with Ohara glass for a clear and true-colour image. A 3″ focuser offers you a generously illuminated field of view and an enormous load-bearing capacity – a great advantage for heavy cameras.

Now in stock: The Vaonis STELLINA smart telescope!

November 6 2019, Elias Erdnüß

Vaonis STELLINA: innovative control, top-quality design, high-tech

Observing the starry sky through a telescope is an unmatchable experience. However, observing some targets can be an anti-climax or even a disappointment: faint nebulae and galaxies are often only visible as shadowy undefined spots of light.

Beautiful details and colours are usually only possible with the help of astrophotography, where the light captured by the telescope is collected and accumulated over long periods of time, creating stunning images of these faint deep sky objects.

Astrophotography however is a hobby with an extremely steep learning curve. For a beginner it can be many months before the first beautiful picture is produced. Even after mastering the first steps in astrophotography, it takes many hours of processing the images before the nebula or galaxy is revealed in all its beauty.

The fully automatic STELLINA smart telescope from the French start-up company  Vaonis  promises to combine the advantages of astrophotography with the direct experience of live observing. This is done in as user-friendly a way as possible since the telescope has no eyepiece, but instead has an integrated camera. This means that images are continually being collected and processed. Using a smartphone or tablet you can watch live as, over the course of a few minutes, more and more details of the target become visible.

The control and operation of the telescope is revolutionary and simple. At the push of a button, STELLINA orients itself completely independently using visible stars. The desired observing target is then selected using a smartphone or tablet. The telescope travels to the correct location in the sky – that’s it!

M83, the Southern Pinwheel Galaxy – with STELLINA, details and colours are clearly visible in the spiral arms.

Of course we at Astroshop were also curious whether  STELLINA  actually keeps its promises. Luckily, we have already been able to test it. As a matter of fact, we have never seen a GoTo telescope that can be controlled so intuitively and easily without prior experience. Even after a short time, the resulting pictures show an incredible amount of detail compared to what is expected from a conventional telescope. Although the quality of the images is not quite comparable to those from a professional astrophotographer, (here an automatic process can’t yet replace the expert), the images are almost immediately visible, not only after hours of processing. Therefore STELLINA is perfect for shared observing with friends and acquaintances.

Until now this telescope was only available by pre-order. From now on  Vaonis STELLINA is in stock and directly available. The ideal high-end Christmas gift!

New Starquest Telescope from Skywatcher

October 30 2019, Stefan Taube

Skywatcher’s new Starquest telescopes combine small optics with a lightweight equatorial mount in a new design. A lightweight aluminium tripod with a storage shelf is also included, the perfect telescope for easy transportation and a quick view of the sky.

Skywatcher Newton 130/650 Starquest EQ

Skywatcher Newton 130/650 Starquest EQ

The high-quality Starquest mount contains a worm gear with 122 teeth on each axis. This ensures high stability and sensitive manual tracking with the easy-to-use flexible shafts – even beginners can easily cope.

The correct telescope to choose from depends on your preferred application:

  • The refractor AC 102/500 shows large sections of the sky. Large objects such as nebulae, open star clusters or comets can be observed with it.
  • The Maksutov MC 102/1300 is particularly compact. Despite its small size, this telescope has a very long focal length. It allows high levels of magnification, and is a real specialist for the Moon and planets – but also planetary nebulae and double stars can easily be observed with the Maksutov. With this selection of potential objects and the rear-facing lens position, the Maksutov is ideal for the balcony observatory in light-polluted cities. Another advantage is the closed optical tube: the mirror cannot become contaminated.
  • The Newton 130/650 telescope is the best compromise. It has the widest aperture and therefore collects most light. Even faint nebulae can still be identified. The Newton telescope is also particularly inexpensive due to its design. However the relatively long tube has the greatest lever effect on the mount.

More information and all the models can be found here in Astroshop.

Celestron RASA Astrographs: Telescopes for Astrophotography

September 20 2019, Stefan Taube

The RASA range of telescopes were developed specifically and exclusively for astrophotography. They are very fast; with a focal length of f/2 they take pictures twenty times faster than a Schmidt-Cassegrain lens at f/10! Because of this a tracking control is not required, and generally fewer demands are placed on the mount!

The RASA 1100 model with a 279 millimetre aperture has already been on the market for some time, and Celestron is now also offering a smaller version, the RASA 800, with a 203 millimetre aperture.

Celestron Astrograph S 203/400 RASA 800

Celestron Astrograph S 203/400 RASA 800

This optical system is also within reach of smaller budgets with the RASA 800, particularly since it can be used with a smaller mount. The illustration above shows the RASA 800 with the AVX mount. This astrograph is optimised for astrophotography cameras with a 22 millimetre field diagonal. The larger RASA 1100 is the better choice for those who prefer to use a DLSR for their photography.

The abbreviation RASA stands for the developers’ names: Rowe-Ackermann-Schmidt-Astrograph. It is basically a normal, routinely-produced Celestron Schmidt-Cassegrain instrument; that is with a spherical primary mirror in front of which is a corrector plate invented by Bernhard Schmidt. Instead of using a secondary mirror to direct the light path towards the Cassegrain focus at the end of the telescope, the camera sensor is incorporated in the prime focus. A corrector assembly comprising four lenses made of especially high-quality glass ensures optimal illumination.

Die RASA-Optik von Celestron

The RASA telescope from Celestron

As the term astrograph implies, RASA telescopes are designed exclusively for photography. There is no option to use an eyepiece. But if you are an amateur astronomer who specialises in astrophotography, you will not see this as a disadvantage, instead you will quickly learn to appreciate the advantages of the RASA telescopes.

Improved Version of the Dobson LightBridge by Meade

February 7 2019, Stefan Taube

No other telescope produces the natural experience of the night sky as directly as a Dobson. Completely without a camera or any other electronic deflection – armed only with an infra-red lamp and star chart – discover nebulae, star clusters and galaxies.

Apart from good weather, two things are necessary to enjoy observation: As large a telescope as possible and a dark night sky. A Dobson is a reflector telescope with a relatively simple base. So, for your money, you’ll get a telescope that is bigger than others. The problem with the dark sky is, however, more difficult to solve. The Dobson telescope should fit in a car so you can drive to a good location for observing.

A large telescope that fits in a car is a contradiction in itself. This is resolved by the Dobson wire-mesh tube:

Gitterrohrdobson

This Dobson in the LightBridge series can be taken apart without tools.

As the figure shows, the telescope can be taken apart into relatively small parts. From left to right, you can see the rocker box, the mirror case, the tube rods and the carrier ring with the secondary mirror. On location, the truss tube Dobson can be built in a few minutes without any tools.

The manufacturer, Meade, was one of the first, with the Dobson telescopes in the LightBridge series to use this form of construction and at a price that is affordable for amateur astronomers. We can now offer the improved version, the LightBridge Plus.

Meade Dobson Teleskop N 254/1270 LightBridge Plus

Meade Dobson Telescope N 254/1270 LightBridge Plus

The new LightBridge Plus has an improved rocker box. It is somewhat lighter, has notched carry handles, a pre-installed eyepiece tray and a friction brake for the height axis. The box can be taken apart without tools so it can be easily transported. Meade now fits these telescopes with an improved eyepiece holder that has a fine-adjustment knob for precision focusing and comes with a high-quality 2-inch eyepiece with a 26-mm focal length.

As with the previous version, the LightBridge Plus has a main mirror fan for faster alignment of the mirror with the ambient temperature. As expected, the optics are fully adjustable. Thanks to the fast aperture ratio, the tube is relatively short and the viewing height at the zenith is not too high.

If you’ve always wanted a telescope with a large aperture, but just didn’t know how you’d carry it around, a LightBridge Plus is a very good choice at a fair price!
