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.

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

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

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
