Altair Astro Starwave 80ED Refractor Telescope with 3" Crayford Focuse

Prijs: 625,00 EUR

 
Product Details

The Starwave 80 ED refractor's ED optics produce a high contrast image with very good colour correction, and the over-engineered optical tube is strong and rigid enough for long exposure astro imaging.
The oversize, tension-adjustable 3.0" Crayford focuser can handle heavy loads like a large eyepiece or DSLR easily. The ED Doublet design offers good colour correction while keeping the optical tube compact enough for transport. The 80ED lens is well regarded for visual observing. Optical smoothness, figuring and low temperature performance is very consistent, and the field is flat enough not to be distracting with wide field eyepieces - with most eyepieces function very well at the F7 focal length.
As with most refractors, a high contrast image is delivered at the eyepiece because there is no central obstruction like mirror telescope designs.
When it comes to astro imaging, the Starwave 80ED optical design has become an ideal choice for customers wanting a cost effective dual imaging and visual capable telescope all in one unit, offering better colour correction than an achromat telescope with same or even longer focal length. The over-engineered 3" rotating dual speed focuser can handle heavy loads, with a direct threaded connection to the optional dedicated Starwave 0.8x reducer.
Tube rings have the standard M6 hole pattern to fit most hardware mounting systems on the market. A Vixen-style dovetail bar and case are included.
You will need a mount, eyepieces and a star-diagonal to use this high quality telescope.
A finder scope or RDF (Red Dot Finder) isn't strictly necessary at this short focal length if you find the object with a low power eyepiece and increase the power from there onwards. Most finder scopes will fit the Starwave 80ED focuser directly, and we recommend the Starwave 50mm Deluxe Finder Scopes, which are a perfect fit, and can be used for an auto-guider when imaging.
The aluminium tube achieves thermal equilibrium very quickly, and the metal construction conducts heat easily to the front optics (essential for imaging) . The over-engineered 3" rotating dual speed focuser can handle heavy loads, with a direct threaded connection to the optional dedicated Starwave 0.8x reducer (reducer option available in dropdown menu below) . Tube rings have the standard M6 hole pattern to fit most hardware mounting systems on the market. A Vixen-style dovetail bar is included.

Specification:

Included:
- 80mm F7 ED Doublet optical tube (555mm focal length).
- Oversize Dual Speed 1:10 ratio 3.0" Crayford Focuser, 360° rotation, with stainless steel rail and tension adjustment (ideal for imaging).
- Crayford focuser rear assembly can be remove for direct threaded attachment to the optional Planostar 0.8x reducer (for imaging).
- Retractable dew shield.
- 2" to 1.25" eyepiece adapter with brass compression rings.
- 2x Tube rings with standard M6 30mm hole pattern (enabling the telescope to be balanced more easily for imaging, or dual-mounted as a guide scope).
- Standard "Vixen-format" dovetail bar.
- Transport case.
