Ruland-Maksutov 300

Work In Progress Posted on Tue, May 27, 2014 19:11:19

Work in progress: Ruland-Maksutov 300


Sky-Watcher is currently prototyping a new catadioptric telescope based on a new design by Lichtenknecker Optics. The design is a sub-aperture corrected telescope with integrated field flattener. The sub-aperture corrector and the field flattener are designed to work as a two group of two lenses system.

The two group of two lenses system allows unrivaled correction. The polychromatic Strehl ratio of the instrument is more than 0.95 for wavelengths between 420nm to 880nm, far better than the diffraction limited value (0.8 Strehl ratio)

From this design Sky-Watcher is prototyping a 300mm F/D 10 telescope with a central obstruction of 0.35 and a 62mm field. Without the need of a full diameter frontal meniscus the weight will be kept below the maximum load of the AZ-EQ6 mount.

Please remember it is a current work in progress and specifications are subject to change (to even better values smiley) anytime in the development phase.



Star Adventurer

Coming Soon Posted on Tue, May 27, 2014 17:24:27

Item: “Grab-and-Go” equatorial mount
Availability: Currently available


The Star Adventurer mount is eager to enter your backpack for remote
astronomy. This equatorial mount designed for deep-sky large field
photography and time-lapse animations supports up to 5kg. payload and
can be configured for a multiple of roles.

Your companion to photography the next remote eclipse or to come along
for your next trip to observe the desert’s nights is now awaiting.



ED Mount

Coming Soon Posted on Tue, May 27, 2014 17:08:50

Item: Equatorial mount for Newton and newtonian astrographs
Availability: end 2014

The ED mount is a revolutionary equatorial mount designed for newtonian
astrographs. The ED mount can track past the meridian without the need
to flip the RA axis (like on German equatorial mounts) and is far more
compact and sturdy than any fork mount.



Dob18

Coming Soon Posted on Tue, May 27, 2014 17:05:01

Item: New lightweight 18″ Dobsonian telescope
Availability: end 2014

The Dob18 is unlike previous dobsonians created by Sky-Watcher. The entire structure is using a skeletal
like design to save on weight. The primary mirror design provides fast
cooling and light weight! The primary is 2″ in
thickness and has a focal ratio of f/4.12 producing a low eyepiece
height! Please
remember this is still a prototype.
