Sale: Beginner Telescope Bresser Messier-130 EXOS-1

December 12 2017, Stefan Taube

The Newton Telescope N 130/1000 Messier EXOS-1 von Bresser is an excellent beginners scope.  The primary mirror at 130 mm diameter allows for observations of brighter deep-sky objects, like the binary star Albireo in the constellation Cygnus, the “double-double” Epsilon Lyrae in the constellation Lyra or the famous Orion Nebula in the constellation with the same name.

Observing the Moon and planets is quite enjoyable  with the Newton, since it does not show any color distortions as a result of its build.

New: Pro camera by ZWO and more accessories for astrophotographers

December 8 2017, Stefan Taube

We would like to present to you a small selection of items that we included in the range recently:

  1. ZWO camera ASI 1600 MM Pro Mono

The ASI 1600 series is the favourite model range by ZWOptical. The ASI 1600 cameras have a relatively large sensor and a small pixel size. There are, therefore, models without cooling that are used mainly by planet photographers and DeepSky cameras that can be used by anyone. We offer the cooled models in a set with special filters and a filter wheel.

The spearhead of this model range is the new ASI 1600 MM Pro Mono. It is ideal for astrophotographers who want to capture faint nebulae with exposures lasting for hours. The incorporated 256 MB of buffer memory provides loss-free transfer even with USB 2.0.

ZWO-ASI-1600-Pro

  1. Orion camera StarShoot AutoGuider Pro Set

If you want to take exposures of several minutes, you should think about tracking control. With this procedure called autoguiding, the mount must run in a controlled fashion because the camera mount must always be exactly oriented towards the desired area of the sky for the shot to be successful. A separate camera is mostly used with its own optics for autoguiding. The camera continually follows a star and gives control impulses to the mount if the star moves.

Thanks to sensitive camera sensors with a high resolution, these autoguiders can be made to be compact. A very well-made example is the new set from the camera StarShoot AutoGuider Pro Mono and the Ultra-Mini Guidescope by Orion.

Orion-StarShoot-AutoGuide

  1. Baader MPCC V-1 Mark III Newton coma corrector set 2”

Newton telescopes are very popular with amateur astronomers because they cost relatively little money and can gather a large amount of light. As with any optical design, Newton telescopes suffer from image aberrations. On the edge of the field of view, the stars are exploded forming a “comet”. What are referred to as coma aberrations are particularly noticeable in astrophotography. The manufacturer Baader-Planetarium offers an excellent coma corrector that is also included in the set with the matching adapters: Baader MPCC V-1 Mark III Newton coma corrector The special feature of this coma corrector is that it does not increase the focal length of the optics. There is as much light as without the corrector, so that the exposure time does not have to be increased.

  1. Oklop padded bag for the Newton 150/750

About the Newton telescope: We now offer padded carrying bags by Oklop. They are made so a specific telescope fits perfectly and can be transported securely without taking up a lot of space.

We offer, for example, bags for the Newton telescope 150/750, Newton telescope 150/1000 or the Celestron telescope SC 1100. Other bags by Oklop can be found here.

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!

Der Astrograph VSD 100 von Vixen

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).

Catalina-VIXEN-VSD100

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: Improvement to the Orion-Dobsons and the Skywatcher EQ-5, new QHY camera and apos by William Optics!

October 27 2017, Stefan Taube

We would like to present to you a small selection of items that we included in the range recently:

1.Orion Dobson telescope N 254/1200 SkyQuest XT10 PLUSOrion XT10 PLUS

Dobson telescopes with 10-inch aperture by Orion are, of course, nothing new. Orion now offers its 10-inch in an improved PLUS version.

New features:

  • Friction brake for the height axis. This enables the use of heavy eyepieces.
  • Filters for observing the sun in safety.
  • Crayford focuser with reduction for fine focusing.
  • 2″ wide-angle eyepiece and Barlow lens
  • Eyepiece tray

With the XT10 PLUS you will receive an easy-to-use telescope with small improvements for even better performance and more fun during your observation sessions!

There is also an 8-inch Dobson by Orion in this improved version: XT8 PLUS.

 

2. Skywatcher mount AZ-EQ-5-GT SynScan GoTo

The AZ-EQ-5 mount by Skywatcher is actually not new. You will receive this mount immediately with a classic tripod as you known it with other mounts. Until now, Skywatcher delivered the mount with a column where the tripod legs didn’t fit right under the mount. This tripod was very compact for carrying, but not as sturdy as the classic tripod.

The AZ-EQ-5 mount is a real all-purpose mount that can take up to 15 kg: It is very light to carry and can be operated in either equatorial or azimuthal position, so for either astrophotography or for simple observation.

The mount is, thanks to the toothed belt drive, relatively light and fitted with the latest version of the SynScan computer control system.

 

3. William Optics apochromatic refractor AP 61/360 ZenithStar 61

Are there any astrophotographers who don’t dream of an apo by William Optics? With the ZenithStar series you will receive a lens telescope in William-Optics quality at a fair price!

The small optics with an aperture ratio of f/5.9 weigh less than 1.5 kg and can be combined with a photo mount. You will receive a light, compact system for travel with which you will achieve amazing wide-angle shots of nebula regions of the Milky way – all that’s missing is the suitable flattener and a DSLR camera.

 

4. ALccd-QHY camera 9c Colour

Alccd-QHY-9c

We are constantly extending our range of cameras by ALccd-QHY. We have recently added the the 9c Colour camera. It has a Kodak KAF-8300 sensor: 8.9 megapixels with a 22.5 mm diagonal and 5.4 µm pixels.

The most important information;

  • The chip is fitted with microlenses.
  • The active cooling with a larger fan cools down the camera to 50 °C under the ambient temperature.
  • The 32 MB SDRAM buffer ensures a quiet transfer of the images.

This camera meets the high requirements of advanced astrophotographers.

Compact and smart: The new mount AZ-GTi from Skywatcher

October 20 2017, Stefan Taube

Astronomy with a smartphone:

It all began with telescopes of the series Nexstar Evolution: Celestron equipped this series with WIFI, so that they can be controlled via mobile units by using the SkyPortal app.

The graphic user interface offers many possibilities and can be intuitively controlled. The omission of a hand controller is another benefit of controlling the system via an app. This way one needs only a limited amount of equipment.

Now available: The new AZ-GTi from Skywatcher:

The mount AZ-GTi GoTo WiFi from Skywatcher is completely new. It carries telescopes with a weight of up to 5 kilogrammes, which can be directed to almost 10,000 sky objects via a smartphone using the SynScan app.

AZ-GTi

With this GoTo control even beginners will easily find their way around the sky. The mount not only swings the telescope to the desired object, but also keeps on tracking, keeping the object in the eyepiece, despite the earth’s rotation.

The mount AZ-GTi is an azimuthal mount, which, in contrast to an equatorial mounting does not permit astrophotography with longer exposure times. However, azimuthal mounts are smaller, lighter and ready more quickly for use than equatorial mounts.

Skywatcher AZ-GTi telescopes:

Skywatcher currently offers the AZ-GTi in three sets. The most inexpensive set is the Explorer-130PS AZ-GTi. Here you can obtain the mount with a Newton telescope and an aperture of 130 millimetres. The combination is not only more reasonable in price, but also has the biggest mirror optics and thus the highest light gathering capacity.

The combination with the 127mm Maksutov is also very interesting: SkyMax-127 AZ-GTi GoTo WiFi. Despite its high focal length, the Maksutov still has a short tube and, as a closed system, is almost indestructible.

An app for the mobile unit offers more possibilities than a hand controller, and the smartphone is always close at hand. Controlling the system via smartphone makes sense especially for small mounts.

Photos taken of the sun in H-Alpha light with the filter QUARK and the new ToupTek camera.

October 13 2017, Stefan Taube

Our Spanish Colleague Carlos Malagon has a clear view of our day star almost every day. He sent us this image of the sun he had taken with the new camera EP3CMOS02300KMC from ToupTek:

H-Alpha-Sonne

The image shows the chromosphere of the sun: This is a part of the sun’s atmosphere above the photosphere, appearing in light with a wavelength of 656 nanometres. This wavelength is also referred to as H-Alpha. It represents a certain excitement condition of the hydrogen atoms in the sun’s atmosphere. At the edge of the sun you see a very nice protuberance.

Besides the camera from ToupTek Carlos Malagon used the H-Alpha filter QUARK from DayStar and the Omegon Pro Apo 80/500 on the mount SkyWatcher Star Adventurer.

This small mount is ideal for travelling. It carries a camera with small optics and tracks it parallel to the rotation of the sky. The Star Adventurer can be screwed on any photo tripod. For this purpose, Carlos Malagon used the Omegon aluminium tripod Titania 500. The photo below shows the complete equipment.

Carlos_Ausrüstung

By the way: Since the sun filter QUARK can simply be inserted into the eyepiece holder between camera and telescope, it can also be quickly removed. The easy to handle equipment can then be simply used to take photos of the night sky.

New telescopes from Omegon: On the right track with Advanced X and ProDob Dobson

October 6 2017, Stefan Taube

The new Omegon telescopes are impressive instruments for any visual stargazer. With the Advanced X and ProDob Dobsonian telescopes, gazing at planets, nebulae and galaxies becomes a lot of fun. Just as with other equipment? No. Because these telescopes are in many ways a lot better than other Dobson telescopes.

Both new series are equipped with a particularly good mirror with up to 94% reflection for bright images. And with a fan which allows you to start observing even earlier.

The Dobson telescopes from Omegon consist of only two parts. Even if you have a stressful day and little time, these telescopes will provide you with many pleasant stargazing hours. Because set up only takes a few minutes, you can start stargazing almost instantaneously. And all this for a lower price than comparable models on an equatorial mount.

Omegon now offers two new Dobson series – in excellent workmanship.

Omegon Dobson telescope Advanced X

A fast telescope for easy observation of planets, star clusters, nebulae and galaxies. Excellent workmanship, consisting of only two parts and very easy to operate. Suitable for any Astro beginner, because no axes need to be aligned. A simple principle: Set up and watch.

  • Teflon pads in height and azimuth axis
  • Primary mirror with 94% mirror coating
  • Primary mirror fan
  • 2” Crayford focuser
  • 8×50 finderOmegon Dobson Teleskop Advanced X

Omegon Dobson telescope ProDob

To make sure that you always stay on track when observing!

Omegon Pro Dobson telescopes for successful stargazing nights.

The new friction system makes the exact alignment and tracking of sky objects an even simpler task. The axes run in needle bearings in azimuth and ball bearings in the height axis, instead of Teflon pads.

This allows even lighter navigation of the telescope and extremely soft following of your movements. Keep celestial objects in your field of view, even with high magnification. An unbeatable advantage! For this purpose the range of high-quality accessories includes: e.g. the Omegon SWA 32mm eyepiece. It is of a much better quality than many other eyepieces, which are normally part of the scope of delivery of other telescopes. Our customers’ reviews: “Super!”, “Simply high-class.” or “[…] just perfect and good”.

 

  • Friction system: ultra-soft and precise movement
  • Needle bearings: soft and exact movement in azimuth – even with just one finger
  • Primary mirror with 94% mirror coating
  • Primary mirror fan: quicker cooling, ready faster for stargazing
  • Red dot finder Deluxe, premium eyepiece 2” SWA 32mmOmegon Dobson Teleskop ProDob

No matter whether you’re a beginner or an advanced stargazer: With an Omegon Dobson under the dark sky, you will experience everything the universe has to offer. If you are looking for a telescope for visual observations you should buy a Omegon Advanced X or ProDob telescope.

Skywatcher AZ-5: The new azimuthal mount for small optics

September 29 2017, Stefan Taube

A small all-around mount for nature observations and star gazing. It does not always have to be the biggest telescope, many times you just want to have a glance at the Moon, planets or the Milky Way. For this purpose, the new mount AZ-5 Deluxe from Skywatcher is just ideal!

Skywatcher Montierung AZ-5 Deluxe mit Stativ

This mount is able to carry optics of up to five kilogrammes, whereby the standardised prism rail connection also accepts telescopes from manufacturers other than Skywatcher. With an optionally available L-holder one can also connect binoculars or a spotting scope with a camera screw.

The AZ-5 Deluxe is equipped with a friction clutch for quick adjustment of the desired object: Simply apply slight pressure to the tube to move the optics to the right direction. Sensitive fine tuning and tracking is then accomplished via two flexible shafts. The mount and optics rest on a sturdy aluminium tripod.

The mount can also be used for nature observations. The fork arm can be adjusted in various positions, so that looking down into a valley is also possible.

Skywatcher also offers the AZ-5 Deluxe in a set with different optics. We would like to briefly introduce these sets:

Explorer_130

The Explorer-130PS AZ-5 is a Newton telescope. Telescopes of this design offer the largest aperture for your money. They gather more light from faint star clusters and galaxies than other telescopes of the same price range.

This telescope in combination with the mount is well suited for beginners who would just like to watch, but not take any photos, and who are looking for a simple instrument for occasional observing sessions on the balcony.

Startravel-102

The name Startravel-102 AZ-5 stands for an achromatic refractor. This optical system is slightly more expensive than the Newton, but has some advantages. The refractor provides sharper images, because it has no secondary mirror in the optical path.

Even experienced stargazers may have lots of fun with this instrument, because it is very quickly set up for use and then enables the observation of large sky fields (“Rich field”) and comets. Equipped with a 45°-Amici-Prism, it is well suited for nature observations.

Skymax-127

The Maksutov Skymax-127 AZ-5 has been a very popular instrument for many years. With its large focal length, it brings the Moon, planets or other objects very close, even on a bright day, with sharp contours.

In combination with a motorised mount, this telescope’s optics are highly suitable for photographic purposes. Looking at it this way, the set Skymax-127 AZ-5 is an investment in the future or a supplement, if you already have an astronomical mount, but would additionally like to have a light AZ-mount and Maksutov optics.

 

 

Useful helpers: StarSense AutoAlign for Skywatcher mounts

September 22 2017, Stefan Taube

People who already have a Celestron mount know about the StarSense AutoAlign module for the automatic alignment of the mount. However, Celestron also offers this technology for Skywatcher mounts: The Celestron StarSense AutoAlign module for Skywatcher.

StarSense AutoAlign Modul

Why is this accessory useful?

Mounts with integrated computer control (“GoTo”) enable the search for sky objects from a database, simply by pressing a button. For this to work correctly, the computer needs some information, like date, time, observation location and alignment of the telescope right at the beginning. You can only use the GoTo control, after having completed the alignment procedure. The StarSense AutoAlign module is a convenient helper who will do most of the work involved.

For this purpose, the module is mounted to the optical tube and not to the finder scope. An integrated camera scans the night sky and runs the alignment automatically. If you are using an azimuthal mount with GPS (e.g. a Celestron CPC) the initialisation and alignment of the telescope will run fully automatically. You only need to switch the telescope on, and wait for approx. three minutes, until it is ready for star gazing!

When using an equatorial mount, you must also align the polar axis with the polar star. Also in this case, the StarSense AutoAlign module will help you: The hand controller of the module will assist you in the polar alignment, so that you don’t need a pole finder. Once the polar axis has been aligned, any further alignment will be automatically performed by the camera, just as with an azimuthal mount.

Use the possibilities of the StarSense AutoAlign for Skywatcher or Celestron for even more fun with your hobby!
