New CMOS-optimised line filters from Baader

July 1 2021, Stefan Taube

The manufacturer Baader presents new filters for astrophotography in the spectral lines H-alpha, OIII and SII.

Filtersets

The half-width of the narrowband filters is 6.5 nanometres, and for the ultra-narrowband it is as little as 3.5 to 4 nanometres. The f/2 filters are optimised for very fast astrographs such as Celestron’s RASA optics.

All filters are available in standard sizes:

With a line filter, astrophotography of luminous nebulae is possible even under a light-polluted city sky! These filters only allow those wavelenghts of light in which the selected celestial object shines to fall on the camera sensor. All other wavelengths are blocked. This produces high-contrast images of planetary nebulae, supernovae remnants and star-forming regions.

Three types of line filters are used in astrophotography, each of which is transparent to the brightest spectral lines of oxygen, sulphur or hydrogen atoms. Depending on the astronomical object, a single filter may be enough for a spectacular image. Combining three shots, each taken through a line filter, creates an ideal result.

The new generation of Baader CMOS-optimised filters is characterised by, among other things:

  • Reflex-Blocker™ coatings, for maximum insensitivity to retro-reflection from adjacent auxiliary optics, even under the most adverse conditions.
  • FWHM on each filter category carefully designed to allow for 1:1:1 exposures, matched for typical CMOS quantum efficiency and S/N ratio.
  • Blackened edges all around, with filter-lead-side-indicator in the form of a black frontside outer rim, to additionally eliminate any reflections due to light falling onto the edges of a filter.
  • Each filter is coated individually, with sealed coating edges.
  • Life-Coat™: Hard coatings to enable a non-aging coating for life – even in the most adverse environments.

Declare war on viruses and bacteria!

January 12 2021, Patric Leibig

During the colder seasons, we spend more and more time in enclosed spaces, therefore increasing our risk of contracting viruses.
It only takes a short amount of time for us to lose our ability to assess air quality as we adapt to smells. This increases the importance of counteracting this.

Significantly reduce the risk of infection due to SARS-CoV-2 / Covid19 (Coronaviruses) and other viruses by using ambient air filters with Hepa H13 filter systems and CO2 monitors.

Seben HT-2008 CO2 Monitor

Air filters reduce aerosols in the ambient air.

SARS-CoV-2 / Covid19 and other lower respiratory illnesses are transmitted via aerosols/water droplets, amongst other things. Air purifiers with class H13 HEPA filters can filter these minute particles out of the ambient air and therefore significantly reduce the risk of infection. A combination of regular ventilation and air purifiers with class H13 “High Efficiency Particulate Air Filters” HEPA filters is the best way to reduce the risk of infection in enclosed spaces. H13 HEPA filters remove minute aerosols (<5µm) from the air and improve air quality. CO2 monitors can also be used to support ventilation.

Air filter

 

According to estimates, the risk of a person in a room becoming infected with SARS-CoV-2 / Covid19 (coronaviruses) due to the presence of a superspreader is reduced sixfold by using air filters with H13 HEPA filter technology.

Monitor and improve the air quality in your office, your flat, the classroom, etc, using the following measures:

  • Proper and regular ventilation / cross ventilation
  • CO2 monitors which support your ventilation
  • Air purifiers / air filters with H13 or H14 “High Efficiency Particulate Air Filter” HEPA filters

Calculating the filter output for your room:

The ambient air filter should be able to filter the entire volume of air in the room at least 2x per hour in order to considerably reduce the concentration of aerosols and particulates. It is easy to work out the filter output you require:

To calculate the volume of your room, and therefore the volume of air, multiple the room’s length x breadth x height. Multiply this result by 2 and you have calculated the filter output in m³/h for your room.

Example:

Length: 5m, width: 4m, height: 2.5m

5m x 4m x 2.5m = 50m³

50m³ x 2 (per h) = 100m³/h

For classrooms / schools or other spaces where groups of people gather, we recommend calculating the air purifier’s output at 5 to 6 times the volume of the room.

Example:

For a room with a volume of 50m³, the air purifier used should have a minimum output of 300m³/h.

New in stock: CO2 monitors

November 6 2020, Patric Leibig

These air monitors display the carbon dioxide content in the air.

What is the ideal maximum indoor CO2 level?
According to the German Federal Environment Agency, indoor air quality is categorised as follows:

  • Good ambient air quality: < 800ppm
  • Average ambient air quality: 800 to 1,000ppm
  • Moderate ambient air quality: 1,000 to 1,400ppm
  • Poor ambient air quality: > 1,400ppm

Regular and proper ventilation…

The German Federal Centre for Health Education and the Robert Koch Institute advise regular ventilation of offices, schools, flats… Indoor spaces in general. Aerosols provide a possible transmission path for Coronavirus SARS-CoV-2 and other viruses. They build up very quickly and disperse themselves in closed indoor spaces. Proper ventilation is important to prevent risk of infection and improve the indoor climate.

Omegon HT-2008 CO2 Monitor

CO2 monitors help you to monitor ambient air quality and support your regular ventilation. Most devices warn you using a traffic light system or alarm sounds as soon as pre-programmed values are exceeded. This is important as people are generally very good at assessing a room’s air quality upon entry but they quickly lose this assessment ability as they adapt to smells, meaning that any deterioration is no longer noticed. We also tend to close windows too quickly when the temperature falls starkly and it gets colder.

The CO2 monitors use sensors to measure the air’s CO2 concentration and show the current carbon dioxide content range using the traffic light display.

These devices use sensors to measure the ambient air’s CO2 content, the temperature and usually also the humidity and therefore help you to learn how to ventilate properly in order to contain viruses.

You can find a large selection of CO2 monitors here in our shop.

Two new ranges of binoculars: BD II XD and SV II

April 1 2020, Betty Lux

This year Kowa have, once again, come up with new ranges of binoculars. With immediate effect you can benefit from the further development of two well-known product families.

Demand a wider angle of view: Kowa BD II XD binoculars

What can simplify birdwatching and the next nature trip? Presumably this is the question the Kowa developers were asking themselves as they put together the BD II XD. The answer is clear: the 6.5×32 model offers an exceptional visual field of 10° with which you will be able to locate birds, animals and other targets much more easily, and observe them effortlessly. On top of that comes greater ease of use – the BD II XD range sits wonderfully in the hand and is compact – as well as special Kowa XD lenses. The advantage: the lens material is enriched with fluorite, a material which yet again hugely increases not just contrast, but also resolving power.

Kowa wide angle binocular BD II XD

However the BD II XD range is not just of interest to ornithologists and outdoor enthusiasts, but also for amateur astronomers. Thanks to the wide field of view and crystal clear imaging performance, you can conveniently and spectacularly enjoy the Moon, the planets and constellations.

Further development of the proven SV range: Kowa SV II binoculars

The Kowa SV range is well-known and tried and tested by birdwatchers. But Kowa is not resting on its laurels, but instead has once again significantly improved their ease of use. The SV II range now has a fresh, green, new look and has improved lens caps which cannot be so easily mislaid. The eyecups are robust, the focusing runs smoothly and is easy to operate.

Kowa bincular SV II

So all in all a real outdoors binocular that offers excellent value for money. This range also includes the KR coating developed by Kowa, which makes the binoculars ready for action in any weather, while ensuring that water or dirt can accumulate on the lenses.

We offer all new products and of course all the well-proven Kowa optics ranges. Click through our selection and you will quickly find the perfect pair of binoculars for you.

The SkyGuider Pro camera mount from iOptron is now available with an electronic polar finder

January 8 2020, Stefan Taube

The SkyGuider Pro is a very light mount on which you can set up a camera with interchangeable lenses or a small telescope. This approach allows longer exposure times and so you can create fascinating wide-angle shots of the night sky.

iOptron Montierung SkyGuider Pro iPolar Set

iOptron Mount SkyGuider Pro iPolar Set

The SkyGuider Pro is now also available as a set together with the iPolar electronic polar finder, which has been built into the mount. With this accessory, you can easily and very precisely polar-align your mount.

The electronic finder has a built-in camera. This shows the position of the northern celestial pole and the location that the polar axis of the mount is pointing at, on your laptop. Simply bring the two points together by turning the adjustment screws for the azimuth and altitude axes of the mount – and you’re done!

SkyGuider Pro mit iPolar

SkyGuider Pro with iPolar

The location of the celestial north pole differs somewhat from the location of the Pole Star. The electronics calculate the exact position using the date and time. Thanks to the sensitivity of the camera and the large field of view, this so-called polar alignment is successful even when the mount has been only roughly positioned. This also works in the southern hemisphere and even takes into account atmospheric refraction at low latitudes!

If want to do without iPolar, you can of course still purchase the SkyGuider Pro mount without the electronic polar finder here.

Omegon MiniTrack LX3: get ready for liftoff with heavenly photos of the starry sky

November 15 2019, Marcus Schenk

A photo of the starry sky that looks exactly how it would look on a clear night in the mountains or in the desert: this is a dream you can now fulfil with the new MiniTrack LX3.  The new mini-mount ensures you are well-prepared and is now even more powerful than its predecessor, the MiniTrack LX2.

MiniTrack LX3 Montierung

The new MiniTrack LX3 mount

It is much easier than you think to take a fantastic photo of the starry sky. You don’t even have to be an experienced astrophotographer. In a dark location, align the mount to the north celestial pole, attach your camera, wind up the mechanism and start your recording. With the MiniTrack LX3, anyone can conjure up a beautiful photo of the starry sky – almost as easy as boiling an egg

Until now you’ve almost certainly been aware of the MiniTrack LX2: a fully mechanical small mount that you can attach to any commercially available camera tripod and which is so compact that it fits into any luggage. The new version, the MiniTrack LX3, has been revised yet again and is now better than ever. Sky&Telescope magazine awarded the MiniTrack the “Hot Product Award” and the users of the MiniTrack are also certain: you can not only take beautiful photos. With the MiniTrack LX3, the starry sky presents itself as if it were on the catwalk.

What has changed?

  1. More load-bearing capacity: now you can attach a camera up to 3kg in weight.
  2. New Teflon bush for even smoother movement.
  3. Adjustable suspension system: you can slow down or speed up tracking, making it more precise and the stars rounder.
  4. CNC body: more stable and even more finely finished.
  5. An optical polar finder is already included. This allows more precise polar alignment of the MiniTrack LX3 – and you can expose your photo for longer.

 

Let yourself be inspired by the Omegon MiniTrack LX3  and learn more about the compact travel mount here.

New Smartphone Mount by Celestron: NexYZ

August 28 2018, Stefan Taube

The trend of using smartphone cameras for photography with optical instruments has remained steady. This is, of course, an obvious choice because everyone has this camera with them, ready to send pictures; and these cameras are always improving. The large range of smartphone mounts  has been extended by Celestron, adding a very interesting model.

NexXY

The  Celestron NexYZ is not only particularly robust; it can be adjusted in all three axes using a rotary knob. This means you’ll be able to set the perfect distance between the eyepiece and the adapter. This feature, in combination with the ease, with which the smartphone can be changed, is interesting for public shots at observatories, because all visitors want to take their personal moon photo home with them.

NexYZ-1

The clamp of the NexYZ adapter is also wonderfully suited for use on spotting scopes.

NexYZ-2

With the NexYZ adapter, we are offering you a smartphone holder with the usual clever design by Celestron.

Observe the night sky with Celestron SkyMaster binoculars!

June 4 2018, Stefan Taube

For many observers is not a telescope, but rather a pair of binoculars that is used as the main optical instrument for exploring the night sky. That is, after all, only logical as real nature lovers are already equipped with binoculars.

Observing the night sky with the binoculars is more than just a compromise – binoculars, with their wide field of view and using both eyes, do have certain advantages over a telescope. And as binoculars are always close at hand in the truest sense of the expression, they follow the golden rule of observing the night sky – the best optical instruments are the ones that are used the most.

The SkyMaster series from the American brand Celestron are extremely popular binoculars often chosen for astronomical observing. These astronautically optimized binoculars offer a generous aperture at a great price.

For successfully getting started observing the night sky with binoculars we recommend the SkyMaster 15×70 SkySurfer set. You get it for the very affordable set price of only 133 Euros!

SkyMaster 15x70 SkySurfer Set

In addition to the binoculars, you also receive a SkySurfer III red-dot finder from Baader, which will help you to orientate yourself in the night sky. The red dot finder projects a red dot onto a transparent window. This lets you see which part of the night sky the binoculars are pointing at and lets you orient yourself using a star chart.

The set also includes is the particularly sturdy Stronghold-Bino tripod adapter from Baader. Unlike the usual adapters made of plastic or aluminium this adapter is made of steel, ensuring that your binoculars are held really firmly and safely on the tripod.

This offer is valid until August 31, 2018. And if you buy the Celestron SkyMaster 15×70 SkySurfer Binoculars set before 27.07.2018, you will be able to observe the lunar eclipse on this date. So make sure you grab yours in time!

Solarquest, the new mount by Skywatcher for observing the sun

April 19 2018, Marcus Schenk

Adjusting your telescope while observing the sun is not as easy as you might at first think. The telescope should, of course, already be oriented towards the sun using a sun filter before setting up. When attempting to orient the telescope towards the sun, you can quickly become careless and peer without eye protection through the telescope at the blazing sun. Help is at hand here with the solar finder or the new Solarquest mount by Skywatcher.

Skywatcher Solarquest

The Solarquest mount has GPS, an automatic level and an electronic solar finder, Heliofind®. You only have to fit the mount. After a short initialisation, the mount moves by itself to the sun. But, of course, the  Solarquest can do more than that: The mount guides the telescope as the sun moves across the sky, so that it is always in line with the eyepiece or camera sensor. This precise tracking can also be done via the built-in Heliofind® finder.

Skywatcher Heliofind

Of course, you can also correct the orientation of the mount by hand, for example, if you are working with greater magnification, and would like to move to a specific place on the solar disc. To do this, there is a slider button on the mount so you can guide the movement yourself.

Solarquest

The azimuthal single arm mount, Solarquest, can hold small optics weighing up to four kilos, making it especially light and quiet. The Solarquest, in combination with a small sun telescope, forms an easy-to-transport system that is quick to set up – that is both particularly comfortable on your balcony at home and ideal for travel or for training purposes.

Skywatcher Vixen

You can also place a small refractor on the Solarquest and fit a sun filter  to it. In combination with a QUARK by DayStar, it is even possible to observe in H-alpha or Calcium-H light. You can even use it for night astronomy without a sun filter using the Solarquest mount. The Solarquest mount becomes a part of your versatile system for night observation.
