November 14 2017, Joshua Taboga

Save 135 Euro – 10% discount – on the QUARK solar filter series!

The QUARK solar filters revolutionized solar observation, because they can be used with an available telescope with a lens just like an eyepiece. The image below shows how simple it is:

The QUARK Filter transforms a standard refracting telescope into a solar telescope.

A detailed test of the filters can be found here in our Astro-Blog.

Of the QUARK-Filter series, the most popular for observations are the H-Alpha-Lichts and the Calcium-H-Linie. In these spectral lines, the sun shows its active side on the daily.

But, you can not only get your hands on any of the QUARK-Filters for a special price: at the moment, we are also offering any of the DayStar Filters at an incredible price!

Additionally, the Solar Teleskope from DayStar Filters, in which the QUARK-Filter comes built-in as part of the set. The most superb of the QUARK-Solar telescopes is the Scout 80 with its carbon tube and helical focusser:

A QUARK filter is build into this 80/1400 Refractor.

The Apochromat VSD 100 by Vixen is now on special offer!

November 10 2017, Stefan Taube

We offer the apochromatic refractor VSD 100 by Vixen at the special prices of €5,399. You save € 600 compared with the recommended retail price! This offer ends on the 31st December 2017. Order now!

The Apochromat VSD 100 is a dream for astrophotographers: With an aperture ratio of f/3.8 it is very fast. That means you only need a relatively short exposure time. That not only means that it can capture more detail in dim objects during your observation night, but that you can do without guiding and get by with a lighter mount. With the Reducer for the VSD 100 you can even obtain an aperture ratio of f/3!

The optical system of the VSD 100 comprising five lenses ensures an even field of view and reduces chromatic aberrations. That provides a sharp image right up to the edge – even with a relatively wide aperture of 100 mm!

This example shot taken on 09.01.2016 shows the comet C/2013 US10 (Catalina).

To achieve a field of view that is sufficiently large, the Reducer is mounted on the VSD 100. 25 shots with an exposure of 30 seconds each were taken with a DSLR camera and added to this overall image. Thanks to the short exposure time, neither autoguiding nor an especially precise alignment were necessary.

New from Omegon: RC Telescopes for Better Astrophotos

November 10 2017, Marcus Schenk

Are you an astrophotographer? Are you looking for an instrument for taking perfect astrophotos? In this case, you most likely may have reached the end of your search. Because there is something for you: the new Omegon RC telescopes.

The Dream Telescope for Any Astro-photographer

Almost all professional observatories use RC telescopes. Coincidence? Probably not. They produce a coma-free field of view by means of two hyperbolic mirrors. When it pans the field of view through an area full of stars, these remain sharp and round, right to the edge of the field of view. Another advantage: the large usable field of view. It is considerably bigger than any other system, like e.g. Cassegrain or Dall-Kirkham. This provides you as an astro-photographer with a higher level of freedom! Take photos even without a corrector with an APS-C sensor.

The reason for enthusiasm: These images were taken by our colleague Carlos with Omegon RC telescopes:

Advantages of the Omegon RC telescopes:

Hyperbolic mirrors: extremely sharp images, large field of view without correctors
Mirrors made of quartz (8″ and bigger): for stable focus and sharp image, no refocusing required
Available as full tube up to 6″-10″ or as truss tube from 12″-16″ aperture
High reflection: 92-94% dielectric mirror coating for bright, high-contrast observations and astro-photography
Quick cooling-off time due to the open design
High capacity electric fan (8″ and higher): minimizes tube seeing and accelerates optical cooling
With 2″ or 3″ eyepiece holder, depending on model

The new Omegon telescopes are the right choice for any amateur astronomer: Choose from six different instruments with apertures ranging from 6″ to 16″.

Die RC-Volltuben gibt es in den größen 6", 8" und 10"

Die RC-Truss-Teleskope für eine stationäre Sternwarte sind in den Größen 12", 14" und 16" erhältlich.

The full tubes of the RC telescopes are available with 6″, 8″ or 10″. With a Vixen style and 3″ Losmandy rail to match your mount. At the top, the tube offers ample space for other accessories, like a guiding system.

The RC truss telescopes with sizes of 12″, 14″ and 16″ are perfectly suitable for a stationary observatory.

Until recently, RC telescopes were very expensive for amateur astronomers. Now let your dream come true: a reasonably priced “professional telescope” for your own mobile or stationary observatory.

Interested? Click here to find the professional telescope for your own observatory. Or ask for a personal consultation on the phone.

By the way: If you are thinking about an own observatory with an RC telescope – why not have a look at our observatory domes. You are planning on a big scale? On request, we will organize the complete construction and accompany your project right to handing over the key.

New carrying case by B+W International in the range

November 3 2017, Stefan Rieger

Known by photographers for many years and now available from us: the outdoor cases by B&W. These very high-quality cases were developed for use in extreme conditions.

B&W Outdoor Case Type 6000

These cases made from polypropylene come in various sizes and colours. If they are often outside at night, we recommend the light-coloured cases because they are easier to see, and you won’t trip over them. As a customer, you can choose whether you prefer an empty case, one with cube foam or one with variable partitions. If your equipment changes, and you want to divide up the case differently, you can always buy additional content later, at any time.

The smaller models are suitable for accessories such as eyepieces and filters (Type 500, 1000), the medium-sized models for astrophotography equipment (Type 3000, 4000, 5000, 6000) and the largest models for mounts (especially for the case series Type 5500).

B&W Outdoor Case Type 6700

The cases comply with the IP67 standard and are water and dust-proof. They can be stacked and have a pressure equalisation valve. Thanks to the eyelets, you can secure your expensive equipment from theft with a padlock. For many models, there is a shoulder strap or a rucksack carrying system as an accessory.

B&W Outdoor Case Type 5000

The stability and permeability of these cases have been subjected to various tests and the outdoor cases have been certified in accordance with the specifications of STANAG 4280, DEF STAN 81-41 and ATA 300.
