Explore Scientific Ultra Light 16" Dobsonian GENERATION II

Explore Scientific Ultra Light 16" Dobsonian GENERATION II

The Explore Scientific Ultra Light 16" Dobsonian GENERATION II is the ultimate in collapsible, large aperture, portable telescopes - featuring full aluminium construction for strength, durability and lightness. This system has very easy to collimate primary and secondary mirrors, which is vital for instruments of this type. The whole telescope folds and packs down into a couple of very compact packages, the main mirror box has a hinged lid for protecting the primary in transit, but also forms an integral part of the structure of the telescope in use. Getting up and observing is a simple procedure: fit the struts and altitude bearings to the main mirror box, fit the Secondary/Focuser head to the support struts, collimate - and you're ready to observe. The Explore Scientific Ultra Light 16" Dobsonian's focuser is a buttery-smooth dual speed low profile Crayford-style/Rack and Pinion Hybrid, capable of supporting the weight of heavier 2" eyepieces and accessories. With 16" or 405mm of pure aperture available, familiar Deep Sky really come to life and a wealth of objects outside the remit of smaller instruments are all within your reach. Planetary and Lunar resolution at this aperture have to be seen to be believed!
