The darkness becomes your stage. Your goal? To capture the night sky in a way that is impossible to see with the naked eye. You can achieve this special success with the right equipment—like our new telescope set offer.
Why this set?
It combines the Omegon Ritchey-Chretien Pro RC 203/1624 OTA with the ZWO AM5 Harmonic Equatorial Mount plus Carbon Tripod. This combination offers:
• Crystal clear, detailed images thanks to a large, fully sharp image circle.
• Modular and made for transport: The compact and lightweight mount is also perfect for travelling.
This bundle is much cheaper in the set than if purchased separately. Perfect for ambitious beginners and professionals, who are ready to take the next step in their astrophotography endeavours.
This great opportunity for you as an astrophotographer is only available until April 15th, 2025 and as long as supplies last.
Get the ZWO Smart Telescope AP 50/250 Seestar S50 and the Omegon handheld planetarium Universe2go+ as a set at a special price.
The offer is valid during the promotion period: 01.10. – 28.11.2024
ZWO AM5 N – the latest generation of the proven AM5 Harmonic Equatorial mount carries telescopes up to 13kg without counterweight and even up to 20kg with counterweight (counterweight and counterweight rod are optionally available). The compact and very light mount, weighing only 5.5 kg, can be used in equatorial mode for astrophotography and in azimuthal mode for observation.
A hand controller and the App for controlling the mount are included in the scope of delivery. Thanks to the built-in WiFi cables are no longer necessary!
Another new feature of this version 2 is that the App now also supports Bluetooth and the dual dovetail clamp has a DC connection, as well as an USB-C port. This means that the cables no longer get tangled up so easily. The AM5 N has a 3/8″ internal thread on its base, so it can be attached directly to suitable photo tripods. GoTo, Live Preview and many other features can now be controlled via smartphone or tablet. This makes the AM5 N ideal for the use in combination with the ZWO ASI Air!
The ZWO Seestar S50 takes a first place in the selection of new smart telescopes. The main reason for this is, of course, the significantly lower price compared to other smart telescopes. But the Seestar can also score points with other features and this may also be seen in the customer reviews in our store. More than 95% of our customers are absolutely happy with the Seestar and this is certainly mainly due to the easy handling, the extremely compact design paired with apochromatic optics and the worldwide good reputation of the manufacturer ZWO, which has been established for many years, especially with astro cameras. ZWO has also incorporated its experience with camera sensors and user-friendly operation via tablets or smartphones (see ASI Air) into the Seestar S50, and it shows.
This smart telescope will delight beginners and advanced users alike, as it is extremely easy and convenient to use, yet still produces fantastic astrophotos!

Innovative manufacturers have been offering astronomical mounts with a special drive design for a few years now. You can find these in the shop under the Harmonic / Strainwave link.
These mounts are equipped with a so-called strain wave gear. It is also known under the protected brand name Harmonic Drive.
The advantages are:
The strain wave gear is used for the axes of industrial robots, among other things. It is therefore a standard and does not need to be specially developed and built for astronomical mounts.
Although the periodic gearbox error is also high for strain wave gears, the error typical of worm shafts, which occurs when the direction of rotation changes (“backlash”), is eliminated. This means that the strain wave gear reacts immediately to the control impulses, so that the periodic error can be compensated very well by autoguiding.
For large mounts, such as the Skywatcher EQ-8, the mounts from 10Micron or the CGX-L from Celestron, a worm shaft is still the first choice, because optics with a long focal length require a very low periodic gear error and a counterweight cannot be dispensed with for heavy optics, even with a strain wave gear. In addition, the advantages of strain wave gears in terms of compactness, weight and price are lost as soon as a mount with a high load capacity is required.
There is therefore an ideal range of load capacity in which mounts with a strain wave gear can play to their strengths. The requirements for mobile astrophotography with small to medium-sized optics fall within this range. The harmonic mounts from brands like iOptron, PegasusAstro, RainbowAstro and ZWO are designed precisely for these requirements.
You can find all mounts with strain wave gear under the Harmonic / Strainwave link in the shop.

The advantages at a glance:
The ZWO Seestar S50 is currently available directly from our stock – so grab it quickly!
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.
