The OCAL PRO collimator has revolutionised precision collimation of reflector telescopes since its introduction in 2021! Now you can get an improved version of the collimator: OCAL V3.0 electronic collimator
Transportation and general usage can cause telescopes to lose their collimation. This is because the scopes’ primary and secondary mirrors shift position. The instrument can no longer show off its capabilities. An abundance of collimation accessories help to redress this.
The OCAL V3.0 uses a camera for this. This makes it unbeatably precise.
The OCAL V3.0 has an entirely new design:
- Inside, it has an in-built, light-sensitive CMOS sensor. This makes collimation easier in poor light conditions.
- Exposure time is also now only 1/20, compared to previous models.
- The OCAL V3.0 has a much bigger lens than both of its predecessors.
- The new OCAL V3.0 can achieve considerably higher resolutions. This makes images clearer, even in critical conditions and improves the precision of the results.
- The new version comes with different adaptors.
You can find further information, price and purchase options using the following link: OCAL V3.0

Binoculars from Celestron’s NATURE DX range are ideal for nature lovers and hikers. They are weatherproof, compact and lightweight – ideal for on the go!
However, the price of these binoculars is perhaps the most impressive thing. Although they have all the features of more expensive brands, they are offered at an exceptionally attractive price. This makes them the ideal companion for all hillwalkers, skywatchers and, in particular, for amateur bird watchers.
The latter benefit especially from the NATURE DX binoculars with ED lenses. The extra-low dispersion lenses provide true colour images at high resolution and contrast – with almost no colour abberations. This is particularly beneficial when observing colourful plumage on bright days.
Binoculars from the NATURE DX range are true all-rounders for all nature lovers!

German manufacturer, Baader, has produced a new filter for 511 and 514 nanometre spectral lines which is available to fit both available filter thread sizes:
These Swan Band emission lines, which are named after their discoverer, are produced by carbon. They make up the majority of a comet’s gas tail in the visible spectrum. The filter only allows light from these two carbon wavelengths to pass through and blocks the ever-present light pollution. Structures within a comet’s gas tail, therefore, become more pronounced even in good observing conditions.
At the same time, it blocks the 501 nanometre OIII spectral lines. This increases contrast and makes it easier to distinguish comets with gas tails from comets with dust tails.
Both C2 Swan Band filters belong to Baader’s new CMOS-optimised filters:

Like a Barlow lens, a telecentric extends a telescope’s focal length. However, the telecentric generates a parallel optical beam. This is particularly important when using etalon filters for solar observation in H-alpha light.
The new Telecentric TZ-4S from Baader is perfect for use with the Sundancer II H-alpha filter. It replaces the integrated telecentric which has a 3x focal length extension. Thanks to the 4x focal length extension created by the TZ-4S, the ideal aperture ratio of f/30 is achieved, even with f/7 to f/8 optics.
The achromatic Telecentric TZ-4S is designed for the entire visible spectrum, and can therefore not only be used with H-alpha systems.

For some years now, the manufacturer Skywatcher has been featuring the Skyliner Classic series: well-proven and highly popular telescopes in the Dobsonian design. They offer great optical performance for very little money because the substructure, affectionately known as a rocker box, is relatively inexpensive.
We have put together the Skyliner Classic Dobsonian Set for you, which is even more inexpensive! The set comprises:
You get the largest telescope in the series, the 10-inch version, which features a 254 millimetre primary mirror, additional eyepieces, a filter for observing the Moon, and a practical laser to quickly collimate the telescope optics – and you save €108.85 on the cost of the individual parts!
All Skyliner Classic Dobsonians impress not only with their optics, but also with their standard equipment: two eyepieces, finderscope, eyepiece holder, carrying handle, and ascension axis tension fine adjustment are standard on all models!
More information, prices and options for ordering for all models can be found here in our shop!

StarAid Revolution standalone autoguider
Now back in stock: the latest ‘C’ version of the StarAid Revolution autoguiding camera
The new ‘C’ version no longer needs a splitter as power supply and data transfer both take place using a USB-C port.
What does the StarAid Revolution camera offer?
StarAid enables you to use your mount’s guided automatic tracking without the need for an additional laptop or PC. This means you can take long exposures of fainter celestial objects! This is known as autoguiding.
With the StarAid Revolution, this is unbelievably easy – autoguiding starts automatically as soon as the camera is connected to a power supply. Point the telescope anywhere in the night sky and the StarAid will find multiple stars which can be used for autoguiding.
Use the StarAid app and built-in WiFi for further interesting possibilities:
- Very simple mount orientation
- Mount initialisation using plate solving
- Special object guiding for comets: Take long exposures of these fleeting objects!
StarAid Revolution works best with a guidescope with a short focal length between 100 and 150 millimetres, such as the UltraGuide MKII 32mm.
You can find additional information about the StarAid Revolution camera here in our shop.

SEGA, the Japanese manufacturer, is expanding its Homestar series of planetariums with a new model. The Matataki planetarium simulates the twinkling of stars and has an integrated loudspeaker that produces atmospheric natural sounds. Choose the sound of the sea, river, or mountain as your soundscape.
As with all Homestar planetariums, you can change the Matataki’s projection disc and choose a new theme from a wide range. It comes supplied with two discs so you can enjoy your new planetarium experience immediately.
The planetarium also features a timer, so it can be used to lull children young and old to sleep.
The Matataki planetarium has a built-in battery that is recharged using a USB cable. This battery means that the planetarium can be used independent of any power supply.
More information, prices, and ordering options can be found here in the shop.

Redshift 9 Premium astronomy software delivers a true-to-life representation of the night sky on your computer.
Of course, the software offers much more besides: simulations of the movement of celestial bodies, 3D models, flights to celestial bodies and many other amazing possibilities! For example, you can observe the night sky from the perspective of an imaginary observatory on Phobos, the Martian moon. The integrated encyclopaedia and 29 interactive guides offer a didactic approach to astronomy.
With Redshift 9 Premium and an Internet connection, you always have the latest data to hand: newly discovered comets, huge star catalogues (e.g. Gaia DR3) or the trajectories of satellites and other spacecraft.
Redshift 9 Premium offers an observation planner and even an ASCOM-standard telescope control for real-world observations. The software can be switched to red light mode for outdoor use.
Redshift 9 Premium is a comprehensive software program with many possibilities, which can be used for learning about astronomy or simply having fun!
Note: Software is for Windows 10 und 11. A DVD drive is needed for installation.
