Sky-Watcher EXPLORER 250PDS 254mm F4.7 PARABOLIC NEWTONIAN Telescope  #10221 + EQ6i PRO Synscan WiFi GOTO German Equatorial Mount & Tripod

Brand New UK Stock, boxed with full Guarantee

The new Sky-Watcher EXPLORER-250PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-250P Black Diamond Series, but with two significant advantages. A Dual-Speed 10:1 ratio focuser is now included for excellent focusing precision. Also the tube length has been slightly shortened to optimise performance for prime-focus photography.

Even better performance for astro-photography and visual use can be achieved when used in combination with Sky-Watcher’s Newtonian coma corrector (Prod.Code 20233)

PARABOLIC PRIMARY MIRRORS
Features High Quality Parabolic Primary Mirrors to eliminate spherical aberrations inherent in 'fast' focal lengh reflectors with spherical primary mirrors. The mirrors are parabolized to bring all the light rays to the same focal point to give sharp, constrasty images, which are full of detail.

SKY-WATCHER DELUXE MIRROR COATINGS
Most reflectors today usually have a coat of aluminium as the mirror surface and then an overcoat of silicon monoxide or silicon dioxide to protect it. Silicon dioxide produces a much more durable coat than silicon monoxide but requires specialized equipment to apply it and is therefore more expensive. Protection is needed, because in most reflectors, the mirror is open to the elements and deterioration of the reflective layer reduces the resolution of the telescope. ALL Sky-Watcher reflectors are Multi-Coated with Silicon Dioxide as standard for Optimum Durability and Long Term Performance.

For amateur astronomers seeking superior equatorial control and the ease of a precision computerized GO-TO system, the EQ6i PRO SynScan is a great heavy duty platform for both visual astronomy and astro-imaging. 

Quiet in operation, the EQ6i PRO has a maximum payload capacity of 25kg and is fully controllable with a smart device via it's Synscan Wi-Fi adaptor using the free Synscan Pro App for iOS, Android or PC.

The EQ6i PRO also features a built-in illuminated polar scope for precision alignment, interfaces for USB, autoguider, optional SynScan hand controller and a SNAP shutter control port for your DSLR (programmable via Sky-Watcher’s free SynScan Pro app for iOS and Android).

Supplied complete with a very sturdy stainless steel tripod with 2" diameter legs and two 5.1kg counterweights.
