Altair Starwave ASCENT 70ED Telescope Visual Bundle

Further details

Featuring Genuine ED optics, the travel-friendly Starwave Ascent 70mm F6 ED Doublet refractor can be taken anywhere. The optical tube folds down to just under 30cm length with the dewshield retracted, and weighs about 2kg. The Starwave Ascent 70ED is capable of both visual observation and wide-field imaging in a single telescope. The included accessories are high quality items, designed to do the Starwave Ascent70 ED optics and build quality justice.

Starwave Ascent 70ED advantages and features
Retractable dew shield (not fixed or removable) for compact transport and quick setup.
All metal. No plastic parts, anywhere in this product.
NEW Quality Rack and Pinion Geared focuser all metal with 1:10 ration microfocus knob.
Focuser has 3 thumbscrews for astro photography (NEW) and a brass compression ring so your diagonal barrels aren't marred.
Focuser rotates independently for framing.
Flat field fast focal ratio F5.6 imaging with the optional 0.8x field flattener/reducer.
Very good photographic performance with better colour correction an Bokeh than some ED lenses costing a lot more.
You won't find anything like these quality accessories in other packages - they would have to be bought separately.
Quality 17mm flat field eyepiece with large rear lens for easy eye placement and comfortable viewing.
Adjustable lens cell tuned at factory and guaranteed to arrive in collimation, giving razor sharp views.
High quality all-metal Red Dot Finder (RDF) with adjustable brightness (not the cheap plastic ones which fall apart and lose alignment).
High quality ultra-durable star-diagonal mirror with 99% reflective dielectric coatings.

Included n the box:
Starwave 70mm F6 ED Doublet optical tube with retractable dewshield.
2" Dual Speed Rack and Pinion Geared focuser, 3x thumbscrews and brass compression ring for holding heavy accessories.
RDF finder with variable brightness, metal body and mounting stalk, plus quick release finder bracket.
1.25" Dielectric Diagonal with 99% reflective coatings.
Wide field 17mm Eyepiece giving 25x magnification, with 65° Field of View (FOV), 16mm Eye Relief, 1.25" barrel and dust caps .
2"-1.25" Push-Fit Adapter with brass compression ring.
Front Aluminium dust cap, and rear plastic dust cap.
Metal mounting ring (rotatable) and dovetail base with standard 1/4-20" threaded "photo tripod format" holes, so you can use the scope with a camera tripod or attach it to the Starwave 200mm Vixen-format dovetail bar.
Carry case with strap, padded foam inserts, and space for accessories. * (FREE item - see note at bottom of page)
Dust cloth for eyepiece and RDF, two allen keys for adjustment of the RDF reticule and for mounting it to the metal finder stalk.

The advantage of ED optics for Astronomical visual observation:
When compared to small Achromatic refractors of similar size, length and focal ratio, the Starwave 70 ED offers better mechanics for easier focusing, and truer colour rendition due to the ED optics. The Starwave 70 ED delivers a sharp "contrasty" image with good colour correction and tight star images. The 70mm aperture gathers about 100 times more light than the human eye, and in a dark-sky location, observation of star clouds and larger more extended objects is most enjoyable. With a higher power eyepiece or Barlow lens, this telescope will show plenty of detail on the moon, and it will show the planetary disc of Jupiter, with the major cloud bands visible across the disc, as well as the four largest Galilean moons and their movements from hour-to-hour. Saturn's rings are visible as distinct from the planet at high powers as is the Cassini Division when the skies permit - a good test of any small refractor.

Feature summary:
The light yet tough optical tube folds down to 30cm in length and weighs about 2kg, sporting a retractable dew shield.
ED optics offer improved colour correction, which produces a higher contrast image, whilst allowing a short, portable telescope tube.
The eyepiece, diagonal and RDF finder accessory package is of high quality, justifying the high quality optical tube.
The dual speed rotatable focuser has a steel bearing plate on the base, and is easily able to carry a DSLR or medium size CCD camera without slipping when the focuser tension is adjusted to suit. Fine focus is easy to achieve with the dual speed 1:10 ratio thumbwheel.
The SW70ED telescope can be mounted on a photo tripod with standard 1/4" thread and for attachment to other scopes or imaging systems, it can be attached to a longer dovetail bar with two commonly available 1/4" tripod thread screws.
