  6. -7% SkyWatcher Maksutov Skymax 127 SkyWatcher Maksutov Skymax 127

    The Sky-Watcher Skymax Maksutov-Cassegrains are the ultimate take-anywhere telescopes. Despite their small dimensions they pack a powerful punch. Their high-resolution, diffraction-limited optical systems are multi-coated to maximize contrast and image sharpness.

  7. The 8" Ritchey-Chrétien is the perfect telescope for astrophotography, but it is also suitable for visual observation.

    • ♦ Aperture 8" / 203 mm - focal length 1624 mm - focal ratio f/8
    • ♦ Hyperbolic primary and secondary mirror for very high sharpness on the optical axis and a large well-corrected field for astrophotography
    • ♦ Both mirrors made of fused silica for stable focus position
    • ♦ 99% high-reflectivy coating on main and secondary mirror for an even brighter image and more contrast - special service from TS
    • ♦ Quicker cooling down thanks to open construction and primary mirror ventilation
    • ♦ Two Vixen style dovetail bars supplied - ideal for accessories like guiding scopes or a piggyback camera mount
    • ♦ High-quality 2" dual speed MONORAIL focuser with 2" / 1.25" reduction adapter - motor focuser optionally available
    • ♦ RC correctors for larger sensors from APS-C upwards are optionally available

  8. The 2" CCD compressor reduces the focal length of telescopes with the factor 0.67x, thus allowing significantly shorter exposure times.

    • ♦ The focal reducer is perfectly suitable for RC telescope. It also works good with Celestron EHD or Meade ACF telescopes or with refractors up to the focal ratio F/9
    • ♦ The image field of DSLR cameras up to APS-C format is illuminated - full illumination up to 29 mm
    • ♦ Easy connection to the telescope via 2" barrel
    • ♦ Optimal working distance from the M48x0.75 thread to the camera sensor is 85 mm - enough space for accessories like off-axis guider or filter wheel
    • ♦ 2" filter thread at the telescope side

  9. The adapter allows connecting 2" accessories to adapters, correctors and focusers with male M48x0.75 thread

    • Telescope-sided connection: M48x0.75 thread (female)
    • Eyepiece-sided connection: 2" receptacle (female)
    • Length: 40 mm
    • Locking via 2 knurled screws and brass compression ring

  10. Introducing the new EAF, the latest innovation from the engineers at ZWO. This electronic focuser enables precise, dynamic focus control for planetary and deep-sky imaging. New version 5 volts

  11. -12% SkyWatcher EQM-35 PRO WIFI SkyWatcher EQM-35 PRO WIFI

    The Sky-Watcher EQM-35 provides a convenient, stable platform for refractors up to 100mm or up to 127mm Maksutovs. Designed as an imaging system, it also works astonoshingly well for visual use. This mount is perfect for the beginner as well as the more advanced astronomer.
    The removable dec assembly allows for the use of Star Adventurer L-brackets or ball head adapters, turning the mount into a heavy duty tracking system.
    If what you’re looking for is a lightweight, stable mount that is precise and easy to use, the EQM-35 is the mount you’re looking for.

    WARNING: the Synscan hand controller has now been replaced by the WIFI controller to be used with the app Synscan Pro by Skywatcher 

  12. The Sky-Watcher AZ5 is an easy to use, grab-and-go telescope mount for visual astronomy and daytime terrestrial observations.
    Constructed from cast aluminium and designed to attach small telescopes up to 9kg in weight, via a regular 45mm dovetail bar.

    • Containing: T-2/32 Diagonal with focusing 1¼" eyepiece clamp (#2458125) and 1¼" nose piece (#2458105)
    • Connection objective side: T-2 internal thread 1¼ "barrel
    • Connection eyepiece: T-2 external thread and focusable 1¼ "eyepiece
    • Excellent for Baader Maxbright binoviewer

    • Much larger prism as in the so-called "Erecting prism"
    • Many Erect image prisms have only 19 mm free passage opening and therefore are not suitable for terrestrial observations at low magnifications, because the field of the eyepiece is shaded by the too small prism.

    • High-quality lense system with apochromatic features, for magnifications from 2x
    • Modular design for visual and photographic (VIP) use
    • suitable for 1¼" and 2" focusers

    • Baader Q-Barlow lense 2.25x, 1¼" barrel
    • dual factor lens assy (1.3x/ 2.25x)
    • Modern High-Transmission Multi-Coating all air-glass surfaces delivers a remarkably brilliant image with extremely low internal reflections
    • Extends the possible focal lengths of the Q-Turret eyepiece set

    • The best visual and photographic filter for contrast enhancement for all telescopes, without loss of image brightness!
    • The effect of the element neodymium as filter material is very impressive. When added to optical glass, it enhances contrast, enhances the red colour in the image (especially with Mars and Jupiter) and it darkens the spectral region which is particularly marked by street lamp light, which is the biggest contributor to the nightly "Skyglow".
    • Planoptically polished and MC-coated – with IR-cut coatings!, without any loss of sharpness as a single filter in front of a binocular or be used for afocal projection with digital cameras (far from the focal point!)
    • The IR spectral range is blocked making stars much sharper when used with dSLRs.
