The tube is made from light weight aluminium alloy with CNC machined components. A tough matte pearl powder coated tube and hard-anodised fittings give durability and great looks.
Visual observing with the Starwave 70ED-R: Detail is easily visible on the larger planets such as Jupiter, with both the four principle moons and main cloud belts easily visible at high power. Saturn's rings and thousands of lunar craters, as well as volcanic plains and mountain ranges are all easily visible. Add a high quality Kendrick solar filter or Daystar Quark Hydrogen Alpha solar eyepiece and you have the perfect 70mm solar observing system. The 420mm focal length is ideal for the Daystar Quark, allowing you to capture the entire disc of the sun at low power, enabling viewing of solar prominences and their development over a few hours. The 70 EDT-R will easliy reveal detail and structure within sunspots with white light solar filters. Viewing bright extended deepsky objects or star-clouds with a low power eyepiece is very rewarding too, with the inherent contrast of a high quality refractor giving objects that visual "pop" against a dark background - something not possible with reflecting telescopes.
Ergonomics: The light weight dual speed 2" Rack and Pinion Geared focuser gives a good balance between lifting power and stability for large eyepieces or cameras. Fine tilt-adustments can be made using the focuser, so you can adjust the optical tube to produce very round stars at this fast F6 focal ratio. The focuser has a 2" rear accessory port with a zero-flex 3 thumbscrew compression ring and a 2"-1.25" adapter with compression ring and dust plug.
Grab 'n go portability: The Starwave 70 EDT-R is a great "grab 'n go" portable telescope-kit for visual observing or astro-photography. The telescope is about the same size as a telephoto camera lens, so it will easily fit in your camera bag.
Mounting the Starwave 70 EDT-R: Designed to fit most mounts which support "Vixen/Synta-format " dovetails such as the Skywatcher EQ5, and so-on will fit directly. A standard tripod thread also makes this instrument compatible with most photo tripods on the market.
Using Starwave 70 EDT-R on a camera tripod as a spotter: Attaching the telescope to a photo or video tripod mount takes seconds by means of the 1/4" photo thread on the dovetail-base. A photo-tripod is perfect for grab and go visual astronomy, digi-scoping and use as a terrestrial spotting scope with superior astro-eyepieces. Astro telescopes usually have higher quality optics than spotting scopes, however they display a reversed, upside down image, which is perfectly acceptable for night-time viewing but not for daytime use. To use your 70 EDT-R as a spotting scope, simply plug in any 1.25" 45 degree erect image prism diagonal and add an eyepiece. which produces an upright, correctly orientated image. Needless to say there are few if any spotting scopes which compare to a triplet refractor with FPL-53 ED glass element when it comes to colour correction and sharpness at high powers.
