Description

TS 6" F6 Newtonian Telescope from GSO on Skywatcher EQ3 parallactic mount
... aperture 6" - focal lengh 900mm - f/6 with 2" crayford focuser
... powerful allround telescope for observing and astrophotography - good quality starter telescope

GSO 150mm f6 Newton on Skywatcher EQ3 

Newtonian telescopes made from GSO for Teleskop Service have a well known reputation for the highest quality optics avaiable in this price range. Due to the very stable steel tube as well as the precice dual speed crayford focuser the GSO 8" f/5 Newtonian telescope is a strongly recommanded combination for astro photography as well as visual observing.

This GSO Newtonian 150/900mm is on of the best solutions in this range. This telescope offers more contrast than the typical 6" f5 newtonian telescope. It adds a package of extra features that are in our opinion unparalleled in this class:

-- high definition parabolical primary mirror, better than typical Chinese mirrors
-- thin secondary mirror spider vanes for minimized obstruction
-- larger illuminated field through use of a well-dimensioned secondary mirror (50mm diameter)
--An ultra-smooth Crayford focuser for much smoother focusing motion and zero image shift.
-- 94% enhanced reflection for a brighter image
-- rigid steel tube instead of a wobbly aluminium tube

The Skywatcher parallactic mount EQ3

Skywatcher N EQ3 Mount

The rigid EQ3 of Skywatcher holds the newtonian telescope with a good stability. This combination is a good choice for beginner. You have a very transportable and rigid parallactic mount and a newtonian telescope without compromises!!

-- good and transportable aluminium tripod
-- upgradeable with polfinder, stepper motors or complete GoTo drive system

The 2" Crayford focuser:

GSO 150mm Newton - Fangspiegel

For this newtonian telescope we have used an excellent 2" Crayford style focuser. These focusers have zero image shift and move very smoothly. This GSO focuser is fully compatible with the TS Motorfocus system, allowing vibration free and easy focusing for high power visual observing or astro-imaging. The crayford holds eyepieces or cameras with a very good stabiltiy.

Parabolical Primary Mirror

The very precisely figured parabolical primary mirror of this telescope is not made of cheap float glass, but rather of BK-7 optical glass that is free of internal stress. Thermic properties are generally better than float glass. At the same time the mirror is way more affordable than more exotic primary mirror substrates that in our opinion bring hardly any advantage at all (see comments under "Primary Mirror Cooling Fan"). For easier collimation the mirrors are properly center marked.
