Explore Scientific Twilight AZ – the uncomplicated mount!

March 27 2017, Stefan Taube

The equatorial mount with GoTo functionality is not necessarily a must-have.  Sometimes you just want to have a quick look at the moon or the planets, search for a comet or observe large areas of the sky with a suitable refractor. In this case, an uncomplicated and quickly available azimuthal mount is fits the bill.

The new Twilight I AZ from Explore Scientific is just such a mount. It accommodates telescopes with a weight of up to eight kilograms – which is quite strong for a mount of this class.

ES-Twilight-AZ

Moving to the desired objects is a simple task: With just one lever each you can loosen the clamps of the elevation and the azimuth axis and quickly move the telescope. Once you have retightened the clamps, you use the two flexible shafts and the precision worm gear for fine tuning and tracking.

The mounting saddle accommodates telescopes with a prism rail, compatible with the very popular Vixen standard. With the enclosed Allen key, the mount arm can be adjusted to optimize the viewing height of your optical system and to make sure that the telescope will not hit the tripod leg. Speaking of tripods: the Twilight I AZ comes with a steel tripod with extendible legs and an eyepiece tray.

The mount Twilight I AZ is currently available for a price of 279 Euro – an excellent price for a mount of this quality!

DeepSky-Set: Cooled camera ASI 1600 with filter and filter wheel from ZWO

March 13 2017, Stefan Taube

ASI 1600 MM series cameras from ZWOptical have really found their place in astrophotography. With its small pixels, the highly sensitive CMOS sensor offers high resolution, and this even in connection with a relatively big sensor diameter.

We now offer the cooled black and white camera of the ASI 1600 series in a set with a motorized filter wheel and suitable filters: ASI 1600 MMC DeepSky-Imaging-Set for a price of 2,019 Euro. You save 29 Euro when compared with individual prices!

ASI-1600-MMC-Mono-DeepSky-Imaging-Set

A camera with active cooling is optimal for taking photos of nebulae and galaxies, because the cooling reduces sensor noise and thus enables long exposure times. This enables you to even take photos of very faint objects in the sky.

Even though the cooled ASI 1600 is available as colour or black and white camera, only the black and white camera offers the full resolution of the sensor. Ambitious photographers therefore favour this variant. In order to show the colour of the celestial object you just simply take photos through three colour and one luminance filters – the latter to increase brightness. The computer then uses these four images to produce a colour image (L-RGB method).

The filters are placed into a filter wheel, so that the camera does not have to be removed and realigned again for each filter change. The filter change simply takes place by turning the wheel. The filter wheel in the Set with the ASI 1600 is electrically powered and controlled via the camera, meaning you do not need an additional cable connecting to your computer. You simply use the camera control to change from one filter to the next, and this, above all, without having to touch anything.

The four filters in the DeepSky-Imaging-Set were specially developed for the ASI 1600. The colour weighting has been optimized for its sensor, which in this case is a high-quality interferential filter. Since the filters are parfocal to one another, the focus position does not change when changing the filter. Besides the three filters for the red, green and blue channel, the set also contains an UV/IR band-rejection filter for luminance.

Just as the graph concerning the filter transparency (transmission) of the set indicates, the filters block out the disturbing light of many street lamps, but are highly sensitive in the red range of the H-Alpha and SII-line. The transmission rate is greater than 92%.

With the ASI 1600 MMC DeepSky-Imaging-Set you receive a high-quality, yet reasonable, camera system with almost unlimited possibilities!

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!

Now available: Omegon Autoguiding-Set with 15% price advantage

February 6 2017, Marcus Schenk

Simply useful for astrophotography: a guidescope and an autoguider, with which you can control your long exposure photographs and ensure perfect and dot-shaped tracked shots.
Omegon now offers a mini guidescope with a 50 mm or 60 mm diameter. With the Touptek Autoguider GCMOS01200KMB Mono the whole system becomes an astrophoto control base.


Even more economical in a set

You can also buy the mini guidescope in a set with the Touptek guider.
Your advantage: buying the set you save up 15% compared with the individual products:
1. Omegon camera Easy Autoguiding-Set50
2. Omegon camera Easy Autoguiding-Set60

 

Why these guidescopes are so convenient

Until recently, photographers used long refractors mounted parallel to the main telescope, which require their own tube clamps, are impractical and, all in all, very heavy. Used on a stationary telescope, there is no problem. But what if you want your telescope to be portable? With the new mini guidescopes, it is as simple never before. Simply mount the guidescope to your existing finderbase, connect the camera – and you are ready to go. Plus, it is not much heavier than a common finderscope. We think this is really convenient! This way you can even use smaller telescopes for taking photos of DeepSky objects.

What are your astronomical plans for 2017? To take your best astrophoto? With our new technology this dream can easily become a reality.
