This instrument is equipped with a high quality 5.1inch diffraction limited primary mirror providing 30% greater light gathering than a 114mm reflector and optical performance with increased sharpness and detail.
An excellent package for those requiring a high quality telescope that is relatively lightweight and compact for easy transportation.
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.
"Our first test on the Sky-Watcher Explorer-130 was to check the collimation of the mirrors, which we found were well aligned. This scope has one of the largest mirrors in its price range, which is a great asset because it means it can gather more light...Optically, the quality of the field of view while studying the star Altair was very good using the supplied 25mm eyepiece. The star remained sharp across 80 per cent of the view, with only slight distortion close to the field edges….Taking everything into account, this telescope made observing the night sky enjoyable and relatively hassle free....great views coupled with ease of use."
