Build your own OpenAstroTech mount!

June 11 2021, Stefan Taube

A photo mount allows you to track the rotation of the night sky on a camera equipped with a photo lens or a small telescope. This allows for long exposure shots of large areas of the night sky.

The manufacturer OpenAstroTech now offers a very functional, yet particularly inexpensive variant of a photo mount. The OpenAstroTracker is a mount you can build yourself!

Building the mount yourself is not only fun and educational, you also get a powerful GoTo mount at an extremely low price thanks to the DIY approach!

Some of the features:

GoTo: The mount comes with full, computer-control functionality. The electronics are compatible with commonly used astronomy software.
Suitable for DSLR cameras with a maximum total length of 35cm (camera body with lens). The maximum recommended focal length without autoguider is 200mm.
High-precision stepper motors: GoTo positioning accuracy of approx. 1 arcmin, tracking accuracy of 25 arcsec, guided accuracy of approx. 1 arcsec.

What you will need: A USB power bank able to deliver at least 5V 1A

The OpenAstroTracker is available in different latitude setting versions. We will supply you with a set that allows you to set up the mount for a latitude of either 35° to 45° or 45° to 55°.

No need to worry: The electronic components are all designed for easy use. No soldering is necessary.

A matching DIY autoguider is also available as an option: OpenAstroGuider V2

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.

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!

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.

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.

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.

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

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!

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!
