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.

LPI-G: Planetary cameras and autoguiders from Meade

November 27 2018, Stefan Taube

 The abbreviation LPI-G stands for Lunar and Planetary Imager & Guider. These cameras from Meade are ideal for astrophotography involving the Sun, Moon and planets. Even small telescopes can safely carry these lightweight cameras. They plug into the telescope like an eyepiece and are connected to the laptop via USB.

Meade-LPI-G-LifeStyle1

Delivery includes Meade SkyCapture software – this allows intuitive operation and use of other programs via the ASCOM interface. The ST-4 socket means the cameras can also be used perfectly well as auto-guiders – that is, for the tracking control of your mount.

The standard version of the LPI-G series has a 1.2 megapixel sensor. The LPI-G Advanced camera offers a wider dynamic range, a 6.3 MP sensor and a high 59 fps frame rate. It has a USB 3.0 port to allow it to handle this data stream,.

The reasonably priced standard version is eminently suitable for beginners who would like to first get some experience. The Advanced model goes way beyond this and allows an intensive experience with planetary astrophotography to develop over many years.

Both versions are available as black-and-white or colour cameras. The black-and-white cameras have the advantage of higher sensitivity and resolution. The cost of colour imaging is higher as you will also need the appropriate colour filters and a filter wheel.

All the models available in the LPI-G series can be found here in the Astroshop.

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.

The new Gran Turismo 81 Apochromatic Refractor by William Optics

August 24 2018, Stefan Taube

William Optics, the specialist for high-quality lens telescopes, is bringing a very interesting “photo machine” to the market with the Gran Turismo GT 81. This refractor features a travel telescope forma-factor, so it’s still easy to handle – a real dream for astrophotographers!

The GT 81 is fitted with a three-element lens that ensures high colour correction and ultra-sharp depiction. In addition to the usual high-quality workmanship of William Optics, the equipment of this apochromatic refractor is worth looking at: A high-quality eyepiece holder, pre-mounted guide scope rings and a prism rail. A special highlight is the patented focus mask that is also included in the scope of delivery.

We are offering a matching guidescope and a field flattener with this telescope. With the Gran Turismo 81 by William Optics, you’ll be receiving a high-quality piece of optical equipment for life-long fun with astrophotography!

New: Star Discovery telescopes by Skywatcher with a smartphone app

June 25 2018, Stefan Taube

An increasing number of telescopes can be controlled with a smartphone. The advantages are obvious: Smartphones offer, with their colour display, touchscreen and GPS mobile, more possibilities and are more intuitive to operate than a classic hand-held controller. The app can be kept constantly up-to-date and the telescope can be controlled wirelessly.

So, the manufacturer, Skywatcher, now offers its azimutal one-arm mount, Star Discovery, without a hand-held controller only. Instead, a Wi-Fi module is included, with which the smartphone can be linked. The telescope can then be controlled with the free SynScan app.

At the moment, Skywatcher is offering the Star Discovery mount with two telescope optics. We can recommend in particular the Star Discovery P1 50i:

Star Discovery P1 50i

The 150/750-Newton optic of this telescope has proven to be valuable for beginners and can be used in many variants. With a mirror diameter of 150 mm, objects from the Deep Sky guide can be viewed, but it is also a pleasure to observe the Moon and the planets with this telescope! Thanks to the relatively small focal length of 750 mm, the telescope is still very compact and transportable.

Those who prefer to observe with a classic telescopic lens should get hold of a Star Discovery 90i. Thanks to its deep eyepiece, it is especially suitable for children.

Both optics can be removed from the mount by way of a handy screw to they can be transported. The Star Discovery has a classic prism rail connector thanks to which almost any small telescope optic weighing up to five kilogrammes can be secured. The mount is also an attractive option if you already have a telescope.

Take another look in the App Store for the SynScan app. You can get the right telescope from us.

New mount from Skywatcher: EQM-35 Pro SynScan GoTo

May 16 2018, Stefan Taube

Many amateur astronomers started their hobby with the EQ-3 by Skywatcher. There’s one reason: The mount is excellent value for money and easy to transport. It can be used as an equatorial mount with motorised tracking for astrophotography and offers the functionality of larger mounts with its SynScan control.

Skywatcher has developed the EQ-3 mount further. We would like present to you the new EQM-35 Pro SynScan GoTo!

 

Die neue Montierung von Skywatcher: EQM-35 Pro

Combine the EQM-35 Pro with a 6-inch telescope. The much-loved Newton optics N 150/750 is very suitable. You will receive this telescope with an improved eyepiece holder: N 150/750 PDS Explorer BD. It has a gear reduction that is useful for astrophotography. If you are interested mainly in photography, the new apochromatic refractor EvoStar 72 ED would be a great choice!

The special highlight of the EQM-35 Pro is the removal declination axis. This way you can use it as a photo mount , with a camera and lens taking the place of the telescope. The EQM-35 Pro then tracks the sky’s rotation, allowing long-exposure shots of larger constellations.

Die EQM-35 als Fotomontierung

With the new EQM-35 Pro, you’ll be getting a versatile and very light mount on a sturdy steel tube tripod. A very good choice for taking up astronomy as a hobby without breaking the bank and a good travel mount for experienced astrophotographers.

Value for money set: Celestron CPC 800 telescope with StarSense AutoAlign

April 27 2018, Stefan Taube

We are currently offering you a valuable set, comprising a CPC 800 telescope and the StarSense AutoAlign module. You save €345.00 compared to buying all the items individually!

Celestron CPC 800 mit StarSense

The telescopes in the CPC series are modern classics! The American developer, Celestron, offers Schmidt Cassegrain optics with this series in a very sturdy azimuthal bracket mount. This compact system is great for when you’re on the move. If you want to drive to a dark sky, you can load this robust CPC into any small car and set it up quickly and easily at your observation site. The NexStar computer control will help you to adjust to interesting celestial objects at night. There are hardly any other telescope systems that will allow you to use your precious observation time so effectively as the CPC by Celestron.

Before you can use the NexStar control, you must first of all initiate your computer. This means you must tell the computer where the telescope is, enter the date and time, and orient it to the starry sky. The CPC telescopes shorten this procedure, too: The built-in GPS tells the NexStar control the location, date and time, and thanks to the SkyAlign technology, you don’t have to already know the stars for initialisation. It’s enough to adjust to three bright celestial objects of your choice in the telescope.

But it gets even easier: With the StarSense AutoAlign module, this last procedure isn’t necessary. Switch on the telescope and just wait for a short while. The telescope will initialise fully within three minutes and be available for you to start your observation session.

The StarSense AutoAlign module is suitable for GoTo telescopes by Celestron. There is also a special version for Skywatcher mounts.

You can now get the CPC 800 with StarSense AutoAlign at a great price!

Celestron CPC Teleskope

The telescopes in the CPC series come with an 8 to 11-inch aperture (200 to 279 mm). With your compact SC optics, these are real all-rounders, and are especially suitable for observing and photographing the moon and planets.

New Skywatcher Apochromatic Refractor: EvoStar ED 72 DS Pro

March 29 2018, Stefan Taube

The telescopic lens tubes in the EvoStar series by Skywatcher have been greatly appreciated telescopes for years for both beginners and advanced users.

With the EvoStar 72, the Skywatcher now offers a dual-lens ED apochromatic refractor at a good price: You can purchase the EvoStar 72 ED DS Pro OTA for just €349.00!

EvoStar 72
The very decently priced EvoStar 72, thanks to its short design, is the ideal instrument for travel, but more than that, it’s great for constellation astrophotography. You only need a small parallactic mount with a load capacity of 5 kg.

The apochromatic refractor has a double lens made from particularly tough ED glass. High-quality glass by Schott is used for the crown glass element. Every glass-air surface of this optical item is fitted with a metallic anti-reflective coat to achieve high maximum light transmission of 99.5 %! The optical construction of this apochromatic refractor considerably reduces chromatic aberrations and creates a much sharper image!

The apochromatic refractor comes with a carry case and a sensitive eyepiece holder with 1:11 reduction. For visual observation, you will also need a zenith mirror and eyepieces. You can find these in the “Recommended accessories” section for EvoStar 72.

We will be pleased to advise you personally!

New Explore Scientific Dobson with 20-inch mirror!

March 6 2018, Stefan Taube

With the Ultra Light series, Explore Scientific is offering telescopes with the Dobson construction that can be taken apart easily for transportation. This means you can travel to dark observation sites with Dobson telescopes. For an unimpeded look into the night sky!

The latest model in the series has a 20-inch mirror: Dobson N 500/1800 Ultra Light telescope.

ES-500-UL

It’s no longer quite so ultra-light. There needs to be two of you to set it up at the observation site. But apart from that, it can be taken apart into practical parts just like the smaller models.

Other features of the Dobson N 500/1800 Ultra Light Hexafoc telescope:

  • Truss tubes made from solid aluminium: Very high level of stiffness
  • Main and secondary mirrors made from quartz with a test certificate
  • Low viewing height of just 1.63 m at the zenith
  • The main mirror can be adjusted from the top, and hence, during observation
  • Very transportable thanks to the small packaging dimensions
  • Large 2.5-inch eyepiece holder with 1:10 fine adjustment
  • Large powder-coated adjustment wheels for wobble-free tracking

The telescope is made in Hungary and Germany

“Hot Product 2018” by Sky & Telescope

February 9 2018, Stefan Taube

At the beginning of each new year, the magazine Sky & Telescope features interesting product developments. The criteria are innovation, an elegant solution to a typical problem, or the particularly high quality of a product.

We would like to present from this long list of “Hot Products 2018” those that we also considered to be particularly noteworthy:

 

Explore Scientific GoTo control PMC-8 with WIFi

ES-PMC-8

The company, Explore Scientific, has developed a control system that, in conjunction with the app, ExploreStars, enables wireless control of astronomical mounts via a smartphone, tablet or other mobile device. You will receive this control system in combination with two tried and tested mounts with completely different load-bearing capacity, namely:

 

Stargate Dobsons by Skywatcher

Stargate-Dobson

For the purists who would rather invest in optics than in electronics, the Skywatcher Dobsonian N 458/1900 StarGate-450P telescope is a dream! The Dobsonian telescope with truss tube, mirrors and a lightweight construction collects a great deal of light, but despite its size, it is still relatively easy to transport.

Sky&Telescope awarded both motorized Stargate versions with GoTo control:

They are equipped with the tried and tested SynScan control system, which helps you to find celestial objects and then automatically guides the telescope.

Mini Star Adventurer by Skywatcher

Mini Star Adventurer

Camera mounts have taken a positive development in recent years. Thanks to the high demand for this very immediate method of astrophotography, manufacturers are always coming up with new innovations. Sky & Telescope awarded the Mini Star Adventurer by Skywatcher. This mount also creates its own WIFI, so it can be controlled via the app. This eliminates the need for a manual control box; control is done wirelessly – and thus vibration-free – and the clear graphic user interface can be used for adjusting your mobile device.

Things that make the life of astronomers easier and lovelier

Orion Astrolampe

The many smaller things on which Sky & Telescope has bestowed the Hot Product Award 2018, include the Astro Lamp by Orion, which, of course, can also be operated with glare-free red light. The editors of the magazine also like:

  • Diagonal mirror with TwistTight fixation for 1,25″ and 2″ connector diameter, also by Orion. This special fixation centres the accessory, keeps it secure, won’t scratch, and can be screwed in place while wearing gloves.
  • The “bible” for one of the most powerful astrophotography programs Inside PixInsight by Springer Verlag. The book is available in English, and is very popular. The book is published in the Practical Astronomy
  • Sky & Telescope has also awarded its own Globes. At least for the Pluto Globe, this is most justified. The globe shows the spectacular view of the dwarf planet, Pluto, as the New Horizons spacecraft revealed in 2015.

Mount and accessories for observatories

Paramount Taurus

We can help you with advice and support for your observatory project. This also includes the high-end products by Software Bisque. So, we are pleased that Sky & telescope has awarded the recently developed bracket mountings, Paramount Taurus.

The Spanish company, Lunático, is making a useful accessory for observatories. Its remote control, Dragonfly, has made it to the list of Hot Products 2018.

Every year, it is interesting to see what products the well-known magazine, Sky & telescope, will award – and we are pleased that every year, these award-winning products are already part of our offer.
