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.

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.

Good things always return: The ETX-125 telescope from Meade

June 29 2017, Stefan Taube

It is available again, the ETX-125 from Meade. Easy to transport, versatile in use and computer controlled – this made the ETX-125 a classic in the past!

ETX125

The advantages of the Meade ETX-125:

  • Compact Maksutov optics: Longer focal length despite the short tube. Ideal for watching the moon and planets, but also for observing nature in the daytime. The robust Maksutov is stable in adjustment and, due to the closed tube, has a well protected mirror.
  • With its opening of 127 millimetres, it is the biggest optics of the ETX series and also suitable for watching objects beyond our solar system: The Orion nebula, the big star cluster M13 in the Hercules constellation, and many other objects.
  • The optical tube is fixed in a bracket mount. It reliably carries the optical system, its motors in both axes align it with the desired observation object and track the telescope in line with any rotation of the sky. The integrated battery compartment provides the required electric current for the motors during outdoor use. However, the ETX-125 can also be powered via an optionally available power supply unit.
  • The tube is actually fixed in the fork, but the fork can be removed from the tripod for easier transportation. The steel pipe tripod carries the telescope without any negative wobbling. Another special feature: The tripod comes with an integrated equatorial wedge. This makes the azimuthal bracket mounting an equatorial GoTo mount, as is needed for astro photography.

And all this for a fair price!

The Meade ETX-125 is a GoTo telescope. This means that it is equipped with computer control, which makes it possible for beginners to find and identify objects in the sky.

The telescope is controlled via the new AudioStar-Handbox:

AudioStar

With AudioStar, you can choose from 30,000 celestial objects. However, the control also suggests objects for watching. A special feature of AudioStar is the audio output. It provides interesting information about the chosen object – however, only in English.

The compact, robust and computer controlled Meade ETX-125 also convinces in its new design!

 

Now available: the new CGEM II mount from Celestron

May 17 2017, Stefan Taube

The American telescope manufacturer Celestron has revised their work horse for astrophotographers. The CGEM II is very popular, and rightly so, because when it comes to load bearing capacity it has a lot of reserves as compared to the smaller Advanced VX mount; but it is cheaper than the big CGX. In the field of equatorial GoTo mounts for mobile astrophotography the CGEM II takes a middle position.

CGEM II

The new CGEM II not only looks very trendy, but it also features a few real innovations when compared with its predecessor.

  • New powerful motor electronics with the latest firmware.
  • USB 2.0 port on the hand controller. This way you can simply connect the hand controller to a PC for software updates.
  • PPEC (Permanent Periodic Error Control) ensures precise tracking.
  • Autoguider port. Indispensable for sophisticated astrophotography!
  • Tracking beyond the meridian.
  • The mounting saddle accepts prism rails acc. to Vixen and Losmandy standard. No adapter required.
  • Improved tripod with height marks: This makes it even easier to place the tripod horizontally.

With this mount, the telescope, camera and guider may have a weight of up to 18 kg. This leaves a really big tolerance range.

We offer the CGEM II, but also as a set together with the Schmidt-Cassegrain optics with apertures ranging from 8 to 11 inch (~200 to 280 millimetres): CGEM-II telescopes.

Combined with the classic SC-telescopes this provides you with excellent astronomical equipment which will give you joy for the rest of your life! If you have extra spending money, you should consider the CGEM II with EdgeHD. This variant of the Schmidt-Cassegrain telescope already has the correction optics for the unavoidable coma error integrated, allowing you to take sharp photos right to the edge.

Whatever you will decide, with the CGEM II you can’t go wrong!

Celestron CGX: a mount close to the limits of perfection

February 27 2017, Stefan Taube

The Celestron brand once again has set the standard for hobby astronomers: The new CGX-mount combines the current technical standard with a well thought out product design – and all for an reasonable price.

CGX-Montierung

Some special features of the CGX-mount:

  • Toothed belt drive and spring pressure mechanism: The belt drive minimises the gear play when changing the direction of movement (“backlash”). The spring pressure mechanism ensures uniform contact pressure between the worm gear and shaft, reducing friction and optimising the operation of the gear – also evident by the reduced noise level.
  • Optical encoders register the position of the mount. The motors can then be stopped before the mechanical slew limit is reached and approach their home position. The mount is able to track objects up to 20° above the meridian.
  • Internal wiring: Only the power supply cable and the cable to the hand control box are exposed. However, the sockets for these exposed cables are arranged in such a way that they do not need to move with the mount.

Der neu konzipierte Antrieb der CGX-Montierung.

  • Large handles: Transport handles ensure easy transport, but all clamping levers are also designed for operation with gloves.
  • Compact design: The saddle plate position near the right ascension axis gives the mount very favourable oscillation characteristics. The declination motor serves as a counterweight.
  • Latest variant of the Nexstar+ control with internal clock to save the last settings and USB-port for simple software update.

Further information on our CGX product page.

Die neue CGX-Montierung mit dem EdgeHD 925 Teleskop.

The CGX-mount is available on its own or as a set with the well-established Schmidt-Cassegrain optics from Celestron. You can find all variants under the link CGX-Telescopes.For ambitious astrophotographers we highly recommend the CGX 925 in its Edge HD version. The most reasonably priced and recommended combination of SC-optics and mount for beginners is the CGX 800.

However, due to the dual Vixen/Losmandy saddle plate you can easily combine almost any other optic from other manufacturers with the CGX-mount.

Now available for a special price: Skywatcher 120mm EvoStar on EQ-3 mount

February 13 2017, Stefan Taube

For years this has been one of the most popular beginners telescopes: the AC 120/1000 EvoStar EQ-3 from Skywatcher. As of today, you can buy this telescope for a price of only EUR 489 instead of the previous EUR 599. You save EUR 110!

A tried-and-tested beginners telescope:

One reason for the popularity of this telescope surely is its classic form. This slim refracting telescope with a focal length of 1000 mm perfectly meets the idea you might have of a telescope. But it does not only look elegant; its power or capacity is also something worth mentioning. With its aperture of 120 mm this achromatic refractor already is one of the bigger telescopes of this design variant. With an aperture ratio of f/8.3 the colour errors have been corrected quite well. As a refractor it offers a particularly high contrast, which has a positive effect when looking at planets. Moreover, with the aperture of 120 mm numerous DeepSky objects, like the Ring Nebula and the far away Globular Cluster M13, are also visible.

EvoStarA solid base that can be retrofitted with motors:

The mount is a further development of the EQ-3. It provides a solid base for medium size optics and is most suitable for taking a stroll across the night sky.

If the equatorial mount is aligned with the North Star before starting a stargazing session, all that is left to do is to track one single axis – the right ascension axis, also referred to as hour axis – to keep the celestial object visible within the eyepiece. On telescopes with basic equipment this tracking is done by hand. However, you can, at any time, retrofit a battery-powered motor for the right ascension axis. RA drive motor for EQ-3-2 mounts.

If you would like to have both axes of the mount motorised, you should choose the EQ-3-2 motor set RA and DEC.

With such a motorised tracking system you can use this telescope to get started with astrophotography. The new EQ-3-2 motor set RA and DEC with ST4 even allows you to connect an autoguider – an advanced piece of technology in astrophotography.

The extremely robust and well-established telescope AC 120/1000 EvoStar EQ-3 can also be adapted to meet your requirements – and this even at a later date, after you have become familiar with the basics.

The portable telescope comes with complete basic equipment, which allows you to start immediately. The equipment includes 2 eyepieces and a relatively big finder scope with an aperture of 50 mm. Just unpack it, take it outside into your garden and start!

This offer remains valid as long as stock lasts – buy now!

 

Omegon APO 104/650 ED: these astrophotos show the beauty of space

January 30 2017, Marcus Schenk

We frequently receive beautiful photos of celestial objects from our customers. They are eager to show us, what they were able to achieve with their equipment. Very often we are over the moon, when we recognise the love of detail and the energy these astrophotographers have invested in these pictures.
Today we would like to present some very delightful astrophotos. The astrophotographer and filmmaker Sebastian Voltmer shows us beautiful impressions of space. These were taken, amongst others, with a Sony a7s and an ST-2000XM camera. The telescope used was a premium telescope: the Omegon apochromat 104/650 ED with field flattener.

Der 104/650 ED-Apo von Omegon
The Heart Nebula IC1805

The name of this nebula refers to its special shape: a red heart in the night sky. You find this nebula between the constellations Cassiopeia, Perseus and Giraffe. The heart is located approx. 4° east of the star ε Cas. An open star cluster, which illuminates the nebula, is embedded in the middle of the emission nebula.

ic1805_omegonapo

The Dumbbell Nebula M27

The Dumbbell Nebula M27 in the Vulpecula constellation is the second brightest planetary nebula and thus a beacon in the starry sky. The originator of this nebula at a distance of approx. 1400 light years is a white dwarf, a star that has reached the end of its life.

M27

Pacman Nebula NGC 281

The names of some nebulae clearly demonstrate that astronomers have a vivid imagination. NGC 281 is also known under the name Pacman Nebula. If you still can remember the time of the Commodore 64 etc., you will surely also remember the computer game. And this nebula with its dark clouds starkly resembles Pac-Man. The nebula is 9500 light years away from us and contains the twin star Barnhard 1. With a strong telescope, we can discover its four companions.

ngc281_omegonapo

Crescent Nebula NGC 6888

Crescent: a half-moon in the form of a nebula. NGC 6888 is also known under the name Sickle Nebula. It is located right in the middle of the Swan constellation, at a distance of approx. 2.5° from the central Swan star, Sadr. Despite its prominent position in summer, the Crescent Nebula is not easy to see because of its small size of 18×13’ and its brightness of 10 mag. Scientists assume that the nebula has been ejected by a Wolf-Rayet star in the later stages of its life. For successful observation you need a crystal clear sky and an OIII-Filter.

Solar flare

The picture gives you an impression of the size of a solar flare in comparison to Earth. This solar flare that appeared on the 15th of August 2016 had a length of approximately 13 Earths lined up.

Celestron Astro Fi: beginner telescopes with App

January 16 2017, Stefan Taube

It all started with the NexStar Evolution: Celestron had this telescope series equipped with WIFI. This enables you to connect your tablet or smartphone with the telescope. This not only gives you the opportunity to control your telescope without cables, you can also utilize all functionalities of the free-of-charge App Celestron SkyPortal: Your display screen uses an appealing planetarium view to show the current view of the sky and provides you with a lot of background information. The most popular objects are available as images and even an Auto-Guide (in English).

Celestron now offers this technology also for reasonable starter telescopes. At present this series Astro Fi consists of four different instruments:

Newton telescope N 130/650 AZ GoTo Astro Fi 130

Refractor N 90/910 AZ GoTo Astro Fi 90

Maksutov telescope MC 102/1325 AZ GoTo Astro Fi 102

Schmidt-Cassegrain telescope SC 127/1250 AZ GoTo Astro Fi 5

astro-fi-5

Our tip: The Astro Fi telescope with SC optics.

The model Astro Fi 5 mentioned last is particularly interesting. With its aperture of 5 inches it is already relatively fast. However, the telescope is very compact and thus only has a minor leverage effect on the tripod. The closed tube protects the main mirror against contamination. Moreover, SC optics show a high adjustment stability. Despite their compact design and the high focal length, SC optics are highly suitable for taking photos of moon and planets – a well suited camera is the NexImage 5.

As already described before, all four Astro Fi telescopes generate a WIFI for the control via the SkyPortal App. In contrast to the NexStar Evolution, Celestron delivers the Astro Fi without an additional manual control box.

Just like the bigger Celestron telescopes, the Astro Fi also come with the SkyAlign technology. This is a particularly simple technique for aligning the computer control to the actual night sky and your station. At the beginning of your stargazing session you must align the telescope to three bright celestial objects, that is all. The telescope uses the angles between the objects and the GPS-data from the smartphone or tablet to calculate the actual view of the sky. After this short procedure you can automatically approach any object that the SkyPortal-App shows you. All you must do, just touch the object on the touchscreen.

The special feature of this SkyAlign method is the fact that you even don’t need to know the names of the three bright objects you use for initializing the control. For beginners this is a great help, but it is also a useful feature for experienced stargazers, because at dawn the number of visible stars is often too low to assign the correct names.

The Astro Fi telescopes are equipped with a battery compartment. However, the best power supply method surely is the LiFePO4 powerpack from Celestron.
