  • Instrument for beginners in deep sky observation
  • Compact, foldable, aesthetic and easily transportable
  • Easy to use

This patented innovation saves space, ease of use and time . In fact, it is not necessary to disassemble the instrument every time it is used, as in "classic" Dobsonians, and reassemble it. The same applies to collimation, after having set it on first use, it does not need to be set again for each observation. In effect, the structure that supports the secondary mirror slides using two rigid rods towards the cage of the primary mirror.

With a 150mm primary mirror, the Sky-Watcher 150mm Heritage Dobsonian FlexTube gets you started in earnest with its ability to collect 73% more light than a 114mm telescope . Under a very dark sky, you can discover your first nebulae or globular clusters (the brightest objects in the famous Messier catalogue). You will be able to locate them and for the Orion Nebula, for example, see many details. In summer with the majestic Milky Way (our galaxy) you can see a maximum of objects.

The Dobson FlexTube Heritage 150 mm promises beginners who want Invest in a telescope that is both bright, without being expensive, many nights of observations rich in discoveries. In planetary observing after collimation, you will reveal many details about Jupiter, Saturn and the Moon using a Barlow or short focal eyepiece.

Optical design

Its Newton-type design offers several advantages over other families of instruments (Cassegrain refractors and telescopes). First, mirrors are cheaper to manufacture for the same diameter and their focal ratio is generally smaller (hence shorter focal length and larger field with the same eyepiece). Then you benefit from an attractive budget with a brilliant telescope . The central obstruction is also weaker than Cassegrain type telescopes, if collimation (mirror adjustment) is well respected, the image quality is good in planetarium.

Unlike very cheap manufacturers, the Newton (Dobson) SkyWatcher has a parabolic primary mirror . First, the mirrors are polished spherically and then trimmed to achieve a paraboloid shape (more expensive and difficult to obtain). This is an essential selection criterion for instruments above 114 mm and with a short f/D.

At once beautiful, efficient and practical, there is no doubt that the Sky-Watcher FlexTube Heritage 150mm will please you and make you appreciate Astronomy!
