The new travel-friendly Starwave 70mm F6 ED Doublet refractor folds down to just under 30cm length with the dewshield retracted and weighs about 2kg, so you can take it anywhere. The Starwave 70 ED is capable of both visual observation and wide field imaging in a single telescope.


Beginner? Why not start out with quality equipment? This is a great scope to get you and your friends familiar with the night-sky or started in astro-photography, without sacrificing optical or mechanical quality. By adding accessories, it has dual terrestrial and astronomical use.

Altair's philosophy is not to start with low quality equipment which inevitably needs to be sold on at a loss to the customer.

The Starwave 70 ED is an ideal beginner's choice for wide-field imaging with your DSLR or compact camera. The Starwave 70 ED is a lot easier to use than a Newtonian reflector, due to it's small size and light weight, and because the optics do not require collimation.

For visual observing you don't even need an astronomical mount right away - the Starwave 70ED will fit a camera tripod to get you started with wide field observation.


The advantage of ED optics for Astronomical visual observation: 

The Starwave 70 ED has good colour correction and delivers a sharp "contrasty" image with 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 as stripes across the disc, as well as the four largest Galilean moons and their movements from hour-to-hour. Saturns rings are visible as distinct from the planet at high powers. 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.


Daytime terrestrial viewing:

By adding an optional image-erecting prism diagonal, the Starwave 70 ED becomes a real performer when it comes to terrestrial and nautical observation, offering performance in the same category as spotting scopes costing many times the price.


Mount choices:

Due to it's compact size, this is an ideal telescope to use with the iOptron Cube or Smart EQ GOTO mounts, or the Skywatcher EQ3 Pro series mounts. However you don't have to buy an astronomical mount right off to enjoy the heavens, because the Starwave 70 ED fits directly to a standard photo tripod, having two Standard 1/4 thread photo tripod holes in the base.


Travel friendly: 

A tough, high quality flight case is included, falling well within any known cabin luggage size restrictions (at 28x39x15cm) to protect your scope on it's travels. The case has enough space inside for a some eyepieces, a diagonal and a finder.


Astro imaging or terrestrial photography with the Starwave 70ED: 

A smooth and rotatable dual speed "non-slip" 2" Crayford focuser is supplied, with tension adjustment, able to carry a basic light weight DSLR or a light weight CCD camera. The focuser sports a steel guide-plate which eliminates slippage and increases the focuser's carrying capacity to about 2.5KG, which is more than enough for a DSLR or CCD camera and filter-wheel. The ED Doublet lens system features a Japanese ED glass element, which results in less colour aberrations in the image. The optics are compatible with the Lightwave field flattener and reducer range, in particular the Lightwave 1.0x Field Flattener (not supplied). The rear 2" visual back can be removed from the focuser, revealing a female M54x0.75x threaded accessory port. Various adapters are available to attach your particular camera system via this method. The machined aluminium tube transmits heat to the optics, which benefits users of dew control systems.


Finder scopes and auto-guiding: An RDF or Red Dot Finder can be attached using a separate finder stalk and Universal Finder Bracket. The Altair 60mm Deluxe Finder Scope / Miniguider system (not supplied) attaches to the focuser directly using the Universal Finder Bracket, enabling auto-guiding and easy guide-star selection, in a compact light weight package.



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 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.
  • A compact and tough foam-filled transport case is supplied with space for accessories.
  • 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.

Please note -

OTA supplied on its own, finderscope/field flattener/mount not included

You will need a 1.25" Star-Diagonal for the telescope to come to focus with a standard eyepiece. You will need at least one eyepiece

For imaging with your DSLR, you'll need a 40mm M48 Extension Tube and M48 DSLR adapter to insert into the 2" focuser aperture.

For CCD camera imaging, you can attach a camera or filter wheel with M54x0.75mm threads directly to the focuser by unscrewing the rear 2" "push-fit" visual back. You can convert this to M48 male thread, by means of an M54x0.75 to M48 converter.
