New: Diamond Steeltrack focuser with Steeldrive from Baader

June 17 2019, Stefan Taube

Diamonds really are astronomers’ best friends – at least since the Baader Diamond Steeltrack focuser has been available. It uses real diamonds in its drive system!

In contrast to conventional Crayford or rack-and-pinion focusers, the Diamond Steeltrack’s micronized drive system guarantees entirely backlash-free operation, is completely non-slip and torsion-free – and has a vertical load capacity of 6 kilograms!

The Steeldrive II motorized focuser drive permits automated focusing of a telescope via computer, as well as precise and vibration-free focusing using the buttons on the hand-held controller.

A good focuser considerably enhances observing pleasure and is essential for high-end astrophotography. The Steeltrack focuser is currently the best possible solution available!

 

iOptron mounts: A new addition to the CEM family

April 4 2019, Stefan Taube

CEM series mounts from iOptron are already widely used in the US and are becoming increasingly well known in Europe too. The CEM25P mount for portable astrophotography with Newtonian telescopes of up to 6 inches aperture and the CEM60 mount for use in observatories have proved particularly popular.

With their new CEM40 and CEM40-EC with encoders, iOptron now provides a middle range mount capable of carrying loads of up to 18 kilograms. The CEM40 is hence ideally suited for astrophotography with telescopes of up to 8 inches (200 millimetres) in aperture.

iOptron CEM40

The CEM40 is the latest addition to iOptron’s CEM series

The abbreviation CEM stands for centre-balance equatorial mount, i.e. for equatorial mounts which are supported at their centre of gravity. This design ensures an excellent relation between weight and carrying capacity. The CEM40 weighs only 7 kilograms and yet can carry OTAs up to 2.5 times heavier. The amazing carrying capacity of CEM mounts has been constantly reaffirmed by our customers – especially regarding the CEM25P.

The CEM40 comes equipped with an electronic pole finder, known as ‘iPolar’. A laptop is required to operate this however, so the CEM40 is particularly suitable for astrophotographers who already use a laptop for their camera. iPolar and built-in GPS provide easy and accurate alignment and GoTo computer control initialization.

The encoders installed in the CEM40-EC version ensure very high GoTo accuracy and allow worm gear permanent periodic error correction – a problem that all mounts suffer from. The CEM40-EC does away with the need for guiding with your astrophotography.

The CEM family now covers a wide range of load carrying capacities, offering a suitable model for every budget!

New: NB1 nebula filter from IDAS

March 25 2019, Stefan Taube

Luminescent emission nebulae, supernova remnants and planetary nebulae are all particularly beautiful objects pertaining to the night sky. This applies both to the simple process of visual observation, as well as to astrophotography. Nature illuminates such nebulae in specific spectral colours: the red light of hydrogen, the blue-green light of oxygen ions and also in the colours of sulphur and nitrogen ions.  Nebula filters enable these colours to pass through whilst blocking the diffused light of the natural luminance of the sky and of light pollution. The result is a marked increase in contrast.

With the Nebula Booster NB1, the filter specialists IDAS are introducing a new, very high-performing filter of this type onto the market, and one that is not overly expensive! As the transmission curve shows, the filter has high transmission and is permeable for all relevant spectral lines, with a surprisingly narrow passband: A real nebula intensifier!

Transmission curve IDAS NB1

 

The filter is ideal for photographing large nebula regions since it enables the typical colours of these objects to pass and blocks the disruptive skyglow. The filter quickly and completely cuts off near infrared up to 1100 nanometres. This is important since cameras are sensitive to this range, but telescopic lenses are optimised for the visible spectral range and are faulty in the infrared range.

The Nebula Booster NB1 is available with two versions which cover both of the common filter thread sizes and can be screw-fitted to the housings of eyepieces or cameras.

New focus motor for Celestron telescopes

February 26 2019, Stefan Taube

When it comes to astrophotography, the right focus is the most important thing. Even the best optics only deliver sharp images if the focus is spot on. A motorized focus has two advantages over manual focusing: it is vibration-free and very precise. If you remotely control your telescope via your PC, you definitely need motorization.

For the very popular SC telescopes of the Celestron brand, numerous solutions from different suppliers have been available. Celestron now offers its own model, the focus motor for SC and EdgeHD optics.

Celestron Fokussiermotor für SC- und EdgeHD-Optiken

Celestron focus motor for SC and EdgeHD optics.

The motor fits all SC, EdgeHD and RASA optics, as well as the two new Maksutovs with CGEM-II and CGX mounts. Exceptions are optics built before 2006 and the 9.25″ EdgeHD. An additional adapter is required for the RASA 1100, as the RASA 1100 is already supplied with a FeatherTouch micro-focus. The adapter requires you to dismantle the focuser partially to fit the motor.

If you are using a Celestron mount, power is simply supplied via the mount’s AUX port. A cable for this is included in the scope of delivery. If all AUX ports on your mount are already occupied, simply use the Celestron Aux Port Splitter.

The motor can be controlled in three ways:

  • With the NexStar+ controller: Simply press the MENU button, select Focuser and you can use the two arrow keys to control the motor and adjust its speed. Version 5.30+ of the installed firmware is required. You can update your Nexstar control via the Internet at any time. The controller is not only suitable for visual observation, but also for astrophotography with a DSLR, i.e. without a laptop.
  • With a laptop or PC: If you operate your telescope remotely or have connected an astrophotography camera, it is best to use the free program Celestron Focuser Utility for Windows. For this purpose, you need to connect the NexStar hand controller to the computer via USB, not the focus motor itself. The new CGX and CGX-L mounts can be controlled with the Celestron PWI software. The focuser can also be addressed via this program. The CGX and CGX-L mounts can be connected directly to the laptop or PC via USB without manual control.
  • Without a Celestron mount: If you have a Celestron optic mounted on another brand’s mount, you can control the focus motor via the USB port. The USB port should supply 900mA. As an alternative to the USB power supply, you can also operate the focus motor via main power or a Powertank. However, a power supply unit or power cable is not included in the scope of delivery.

The Celestron focus motor for SC and EdgeHD optics is a really useful accessory that is easy to adapt and operate.

ASIAIR – astrophotography has never been so easy!

December 17 2018, Elias Erdnüß

The brand ZWO is, especially thanks to its powerful and user-friendly CMOS astrocameras, a frequently heard name in amateur astronomy.

With the ASIAIR control unit, ZWO now promises to fundamentally change the astrophotography scene! It’s a compact computer (Raspberry Pi), that is secured to the telescope of the mount. The device can do everything you expect a computerised telescope system of the 21st century to do!

Mount, camera, filter wheel, and autoguider are connected with the ASIAIR. Via an app for Android or iOS, everything can be controlled centrally and wirelessly via WLAN from the smartphone or tablet. You’ll no longer need to take your laptop with you to autoguide and to use cooled astrocameras. There are also advanced functions such as plate solving at the press of a button.

 

 

ASIASI communicates with the telescope mounts via the instrument neutral distributed interface (INDI) and so is compatible with most available GoTo mounts. The only snag: The device only supports ZWO cameras, autoguiders and filter wheels.

Other manufacturers like PrimaLuceLab with the EAGLE 2 are following similar approaches to computerisation. This one may feature higher performance and a wider range of functions, but there’s also the user-friendly ASIAIR for just a fraction of the price.

SALE: The Hyperion Universal Mark IV zoom eyepiece at a special price!

December 12 2018, Stefan Taube

A zoom eyepiece is really practical: It combines several focal lengths that can be adjusted simply by rotating the body. So, you don’t need a whole eyepiece set, and don’t have to switch them out if you want to increase magnification. Unfortunately, zoom eyepieces do not attain the edge sharpness and field of vision of a fixed focal length lens.

With the  Hyperion Universal Mark IV zoom eyepiece by Baader Planetarium it’s a different matter! This tried and tested zoom eyepiece has been improved even further, and offers, for magnification factors with 24 to 8 mm focal lengths, a very good image and at the greatest magnification factor, a field of view of 68°. Unlike other zoom eyepieces, the field of view is not narrowed at greater magnification!

You can now purchase the Hyperion Universal Mark IV for just 220 euros. You save € 25 on the recommended retail price!

Hyperion Mark IV Zoomokular

In the set with the 2.25x Barlow lens you can now even save 27 euros!

The word universal in the name of the Hyperion Universal Mark IV aims to offer almost unlimited uses: Use the zoom eyepiece visually with a long focal length Dobson telescope to view the planets and planetary nebulae, or with a Bino viewer or with a spotting scope for bird and nature watching.

This zoom eyepiece is also very good for a-focal photography:

Many adapters are available for the wide range of uses of the Hyperion Universal Mark IV.

By the way: Until the end of January 2019, you can purchase Hyperion series eyepieces at a special price!

New: Celestron Powertank Lithium Pro

November 29 2018, Stefan Taube

 The Celestron Lithium Powertank has quickly proven itself and is already used as a power supply for countless astronomical telescopes. Celestron has now also packed two LiFePO4 elements into one battery to give twice the power with its Lithium Pro Powertank!

Celestron Lithium Pro 1

Some special features:

  • Up to 17 hours of power for your telescope!
  • Multiple devices can be powered simultaneously.
  • Socket for vehicle power plug (cigarette lighter cable). This cable is included with most telescopic mounts as an accessory.
  • High shelf life – unlike other power tanks, this battery does not need to be used regularly in order to maintain its performance.
  • Long operating life – up to 2,000 charging cycles, which only take about 3 hours.

Like its little brother, the larger Powertank also employs Celestron’s well thought-out design – it can be attached to the tripod with the loop and Velcro fastener provided. The torch has a red light function and the lid with the connections can be closed to protect against dust and moisture.

Celestron Lithium Pro 3

Thanks to its cigarette lighter connection, the Lithium Pro Powertank can be used with almost any mount. A powerful portable power supply such as this is highly recommended for slightly larger mounts, such as the Celestron CGX or the Skywatcher EQ6-R.

Celestron Lithium Pro 2
