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.

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!

iOptron: A variety of astronomical mounts

September 15 2017, Stefan Taube

Mounts from iOptron are becoming more and more popular, not only in the USA, but also in Europe. Reasons for this also include product diversity, mechanical quality and excellent equipment. Let us introduce a selection of mounts from  iOptron:

The iEQ45 Pro GoTo is of particular interest for astro-photographers.

iEQ45

The mount can support twenty kilogrammes and is thus in the size range that is preferred by most ambitious amateur astronomers. It can also accommodate ample sized optics, but is still easy to transport. The tripod with its 50 millimetre legs ensures stability.

While stargazing, the iEQ45 Pro is quickly ready for use. Its readiness is assured by the integrated GPS, the electronically supported alignment of the mount with the polar star and the various initialisation methods for the GoTo system. The GoTo system will assist you in finding your way through the sky. The iEQ45 Pro is equipped with an eight-line remote to make sure that you won’t lose track.

If you are a novice and would like to start slightly smaller, then the CEM25P GoTo would be the right choice. This mount is available for a considerably lower price, but still is able to carry 12 kilogrammes. A 6-inch Newton telescope is a good match for this mount.

 

Unbelievably quiet and load-bearing AZ Pro GoTo

AZPro

The only time you need an equatorial mount is when you want to take photos of faint nebulae and galaxies. In all other cases, the azimuthal mount AZ Pro GoTo is a highly interesting alternative. The AZ Pro is simply remarkable: It works almost silently, when carrying even heavy optics of up to 15 kilogrammes!

This mount does this with all imaginable comfort: Large display, GPS, automatic alignment and installed power pack. You don’t need a Powertank! Without an external power supply and due to its dice-shape design, the AZ Pro is very compact – more mobility is hardly possible!

With an azimuthal mount of this kind, you can, in addition to visual observations, also take photos of the Moon and planets, or use the Atik Infinity camera for video astronomy.

 

The smallest mount from iOptron is the SkyTracker Pro

SkyTracker

Over many years, the photo mount SkyTracker Pro has found lots of friends. No further explanation required.

Photo mounts like this one enable astro-photography directly with a DSLR, i.e. without any telescope.

This is simple, possible anywhere and very well suited for taking photos of large constellations, allowing you to take photos of the Milky Way or just atmospheric landscape shots with the night sky.

 

The observatory mount from iOpton: CEM60 GoTo

CEM60

With a load bearing capacity of 27 kilogrammes, the CEM60 GoTo is not the biggest mount at Astroshop. However, it is a very interesting solution for stationary operation on a concrete column, because it meets the requirements of many small garden observatories and is available for quite a reasonable price.

Special ports below the dual mounting saddle enable the operation of accessories for astro-photography applications. In case you do not want to constantly operate the mount stationary, the scope of delivery also includes a transport case. For mobile use, we can also supply you with the matching iOptron tripod or even an especially high-quality wooden tripod from Berlebach.

This is a selection of particularly interesting mounts from iOptron. You will find the whole product range here.

Experts on Tour – Leica has invited us to deepen our expert knowledge!

August 1 2017, Stefan Rieger

In order to refresh our expert knowledge, we occasionally get up early in the morning: The plane to Hamburg took off at 6 o’clock already, from there we travelled to Schleswig-Holstein. Leica had invited us to comprehensively check and compare their range of binoculars and spotting scopes over a period of two days. For this purpose, we travelled to the Kaltinger Watt. During a walk through the tidal flat and intensive watching out of the sheds of the NABU station, we were able to put the Leica binoculars and spotting scopes extensively to the test.

Hinflug mit Nikiair MUC-HH

During a delicious supper in a sociable group of people with dealer colleagues and Leica employees we explained which product developments the market is looking for. Let’s see, whether the one or the other idea will find its way into the product development.

On the second day, a theoretical part first explained, what a Leica product is characterised by. Leica describes this as the “Leica-DNA”: A specification profile that any product in the Leica portfolio must attain in order to make it from development to production.

The Leica DNA includes:

  • Compared with other premium products in their class, Leica products should have the best balanced transmission curve in the visible wave range of the light. This ensures excellent contrast and outstanding colour neutrality.
  • Besides the optics Leica also places high demands on the mechanics and the robustness of the housing. All models must pass some tests, both during the development phase and, at random, during ongoing production. As an example, Leica binoculars must withstand temperatures from 40 to 85 degrees over hours, i.e. they must work correctly immediately after. They must also withstand sudden shocks.
  • Leica products should always be the most compact binoculars of their class, but still highly ergonomic. For this purpose, Leica tries to balance the weight perfectly in comparison to their competitors, so that tipping the binoculars does not always need to be prevented by hand.
  • All Leica binoculars and spotting scopes are made for everyday use!

The following series of binoculars are currently in the Leica product range:

Leica Noctivid - das Non-Plus-Ultra für den Naturbeobachter

Leica Noctivid: This is currently the non-plus-ultra in binoculars for nature and bird watchers. Due to the extremely short close range of approx. 1.5 metres, it is most suitable for watching insects and crayfish as well as plants. Among the premium binoculars from European production, it currently offers the biggest field of view of its class and has – as preferred by many nature observers – an open bridge. Moreover, this instrument is characterised by a very plastic representation, which gives the impression of a very high focal depth.

Leica Ultravid HD-Plus, hier in der Sonderserie

Leica Ultravid HD-Plus: The Ultravid HD-Plus is the successor of the legendary Ultravid HD and the Ultravid models. At present, it is still one of the most compact binoculars for discerning customers. This model has not been changed from outside, but the newly developed coatings have been adapted to the SCHOTT-HT-Glass that is now used. This allowed for a further improvement of colour purity, contrast and transmission.

Leica Trinovid HD 8x32

Leica Trinovid HD: Leica binoculars have been available under the name Trinovid already since 1963. This model designation is therefore very popular and known by many nature observers. Even today one can see models from the 60s and 70s hanging around the neck of some nature observers. In the meantime, so-called HD glass is also used for the most current version of the Trinovid HD series. This increases the contrast range and reduces colour fringes, leaving you with a much clearer and sharper image. As a measure to slightly reduce the production costs, this binoculars model is produced in their own factory in Portugal. The quality and manufacturing standards are obviously the same as in their factory in Wetzlar. The Trinovid HD series addresses users, who would rather keep an eye on their money, when it comes to judging between costs and the last percent of what is optically possible.

Leica pocket binoculars: Even with the pocket binoculars there is a differentiation between Ultravid and Trinovid. The Ultravid has a shorter close range, a slightly better image performance and, apart from that, is nitrogen filled and thus watertight and protected against steaming up from inside. The Trinovid is a classic, which, in its present form, has been available since the 90s. But still excellent and, above all, compact binoculars.

Leica Geovid 8x56 HD-B

More interesting for hunters is the Geovid series with integrated rangefinder. Moreover, for customers looking for something special, there are various models or edition models.

Leica APO Televid 82 W

In case of spotting scopes the selection is more limited. Here there is only one series “APO Televid” which is available with various aperture diameters and always with straight or inclined view. The Vario Eyepiece is a so-called wide-angle eyepiece and provides a magnification range of 25-50x for all models.

In the field of digiscoping, Leica supplies adapters for their own cameras, but also for system cameras and it is currently the only adapter with diopter compensation in the market. This is simply made to fit via an optional T2-ring for the DSLR or system camera.

Leica Beobachtungshütte am Katinger Watt

All in all, a very successful journey. With less sleep, but excellent impressions concerning Leica products, the Leica market consciousness and the bird life at the North Sea. Over the next few days my colleague will write a bit more about our observations.

Astronomik: new clip filters for Canon DSLR cameras

July 31 2017, Stefan Taube

Northern German company Astronomik is a specialist for astronomical filters for astrophotographers or purely visual star gazers. Clip filters are a special innovation of Astronomik. These filters have a special mounting shape, which allows them to be placed directly into a DSLR or system camera – without using any tools!

Astronomik currently offer clip filters for:

The camera mentioned last is designed with extremely high sensitivity. We offer this camera as a specially astro-modified camera. For more information please follow this link: Sony Alpha 7s Astro.

For APS-C Format EOS cameras from Canon, Astronomik have now developed a new series. A special feature of these new XT filters is the very thin carrier with a thickness of only 0.3 mm, to which the filter layer is applied. When using filters with thicker glass carriers, image faults may become visible in the corners of the photos. Stars appear slightly dash shaped. This can be particularly noticed when using short focal lengths. So if you would like to use a Canon EOS with the camera lens on a camera mount to take wide angle shots of the night sky, an XT filter might be the right investment.

XT filters are available in the usual versions, from CLS to H-alpha all the way to SII filters. For novices we especially recommend the CLS filter, which suppresses artificial light pollution.

The red transmission curve reveals: The CLS filter blocks the light from the yellow street lamps.

By the way: Removing a clip filter from the camera housing is just as easy as putting it in.

SkyGuider Pro: the large camera mount from iOptron

July 17 2017, Stefan Taube

The SkyTracker Pro from iOptron is one of the most popular camera mounts. This handy unit tracks photographic equipment of up to three kilograms in weight to follow the rotation of the sky. This allows you to take panorama shots of the night sky with long exposure times.

The new SkyGuider Pro from iOptron can even carry up to five kilograms of photographic equipment. This is easily sufficient for a small telescope, such as the Photography Scope with camera. The scope of delivery already includes a mounting plate for small telescopes.

The scope of delivery also includes a counterweight for balancing the photographic equipment. This provides stability and takes pressure off the rotation axis.

However, you can also install a second camera with up to three kilograms in weight instead of the counterweight. This way you can take photos of the same sky area, but with two different focal lengths.
Alternatively, you can use the second camera as an autoguider.

On the product page for the iOptron Mount SkyGuider Pro you will find an illustration showing the vast variety of applications for this camera mount.

In addition to the counterweight, the scope of delivery of the SkyGuider Pro includes almost everything you need. The only thing missing is a tripod and a ball head might also make sense. Both these articles can be found under the tab “Recommended Accessories” on the product page.

The SkyGuider Pro comes with a power pack which can simply be recharged via USB. There is hardly any mount for sky photography available for use with photographic equipment of up to five kilograms in weight, that is more light-weight or more compact. As with other mounts from iOptron, the SkyGuider Pro also offers a satisfying, solid mechanical design. We are convinced that this new camera mount will meet your approval!
