New entry-level Dobsonian telescope from Omegon
January 28 2024, Benjamin Mirwald
The Omegon-Dobson family has grown. The Advanced X N 152/1200 telescope expands the “Advanced X” series with a high-quality, yet affordable model.
With a mirror diameter of 152 millimeters, it collects enough light to see even distant galaxies. The slim telescope shows its strengths primarily when observing planets and star clusters. The focal length of 1200mm makes it easy to achieve slightly higher magnifications. The included 25 mm eyepiece gives 48x magnification, with additional eyepieces a range of 30x to 240x is usable. We particularly recommend the Premium Flatfield eyepieces as accessories.
Sometimes at high magnifications you can see the flickering of the air, but there are nights with perfect “seeing” – and this telescope is made for them. As a Dobsonian telescope, it consists of two parts and is ready for use in just six steps:
- First set up the so-called rocker box (8 kg),
- Place the optical tube (9 kg) in the rocker box,
- attach springs on sides,
- slide in the finder scope,
- insert eyepiece.
- Don’t forget: remove the lid 😉
This only takes a few minutes. So it is possible to simply peek through a few gaps in the clouds every now and then. The good-natured design is also suitable for use all night long – the telescope can easily handle dew or frost.
A Crayford focuser for 1.25″ eyepieces allows you to precisely focus on the celestial object.
Because it is intuitive to use and really robust, the instrument is highly recommended for children aged 10 and over.
Like its larger siblings in the Advanced X series, the N 152/1200 can also be retrofitted with a digital “sky navigation system”, the Omegon Push+ Go system. The 6×30 finder scope is the classic way to find the objects – in combination with good celestial atlases .
Tecnosky OWL – magnificent, sharp focusing apochromats
January 27 2022, Jan Ströher
A few years ago the Italian company, Tecnosky, started producing their new, own-brand triplet apochromats known as “OWL”. The first model in the series was the OWL 80/480 apochromat, which was released in spring 2021. The OWL 90/560 was hot on its heels, with the OWL 130/900 SLD soon following in autumn. Soon the range will be blessed with new 70mm and 125mm aperture models. All OWL telescopes are based on a triplet lens design with FPL53 fluoride glass. However, the soon-to-arrive 125mm OWL will be an ED doublet.
The OWL 90/560 triplet
These features, combined with fully multi-coated lenses, blackened lens edges and a lens hood on the tube guarantee Strehl ratios upwards of 0.95! An optical interferometric certificate is attached to every single OWL telescope. Every specimen, therefore, undergoes a detailed quality check before distribution.

These compact apochromats are great devices for astrophotography and also offer first-class, pure-colour image quality and joy for observing. Tecnosky also supplies reducer-flatteners calculated to suit the optics for each model. This means that OWLs, with their aperture ratios of f/6 – f/7, are ideally suited to photography.
Aesthetically, these “owls” also make an impression – they are all manufactured from high quality materials, are multi-coated, elegantly manufactured and have a white, black and red colour scheme to complete their look.

All OWL models come with compatible prism rails, pipe clamps, Vixen viewfinder shoe, carry handle and retractable dew shield. These are this apochromat’s main features alongside the rotatable focuser with 1:10 reduction and locking mechanism, as well as a sturdy carry case. All in all, you get a first-class telescope with numerous great features for a reasonable price for this size category. The OWL 70 and 125 models will be available in our shop from spring 2022.
