Skywatcher Skyliner 400P 16 "F / 4,4 FlexTube Dobson Pyrex Telescope


Skywatcher Skyliner 16 "FlexTube Dobson - opening 406mm / focal length 1800mm

Transport, assembly and operation have never been so easy.

An evolution of the Dobson by Skywatcher: The Skyliner series.
The tube can be pushed together. Due to its ultra-compact dimension, it is ideal for transport and storage. For observation you have to pull the tube apart and have within seconds a fully operational and adjusted telescope. Do not worry: when fully extended this Dobson has a high stiffness.

The Skyliner 16 "FlexTube Dobson

This is the largest Skywatcher Dobson, a larger system would then have to be stationary. This one, however, can still manage and build a strong person by itself.
16 "opening is a limit for a transportable Dobson.
At this mirror diameter you can see the structure of nebulae and galaxies, details are resolved. Finest details in nebulae and galaxies reveal edge stars of star clusters, do not stay hidden from you. Even the color perception with some bright mists is possible!
Details in abundance in the moon and planets will captivate you for a long time, this abundance of image information will not cease. The excellent optics and its enormous image brightness make every observation a special pleasure. The visual image is already reminiscent of the quality of professional recordings!



SKFXD16 Skywatcher Skyliner 400P FlexTube

The adjustment of the Skyliner 16 "FlexTube:
The telescope sits on a so-called Rockerbox, which forms a stable, wobble-free substructure. The desired sky objects can be targeted by pushing on the tube.
The tripod plate runs on plain bearings and the telescope can be rotated by the side handles in the desired direction (azimuth). The height adjustment has a so-called "Tension Control" (see picture above). This allows you to adjust the movement of the height adjustment and even clamp the telescope firmly.

The 2 "focuser:

The Dobson is equipped with a smooth and precisely worked 2 "Crayford focuser with a reduction for 1.25" accessories. You can thus use powerful 2 "eyepieces, a bright picture and a broader view is possible.All 1.25" eyepieces can of course also be used.
Since the drawer is ball-bearing, heavy and accurate adjustments are guaranteed for heavy accessories.
To achieve a particularly accurate focus, the extract has a 1:10 micro reduction.

The mirror carrier made of Pyrex: It is characterized by a rapid cooling and offers even during the cooling phase a slightly better picture than other mirror carrier (such as Float glass or BK7). Cooled, the type of mirror carrier is no longer crucial, concerning the quality of the image. Here it becomes clear that the advantage of the PYREX is the fast operational capability of the telescope. Diffraction-limited imaging of the telescope is guaranteed.
