Askar 80ED

Askar 80ED - versatile ED 80/560 telescope for deep-sky and visual observation

Visit Askar 80ED is a telescope with a diameter of 80 mm and a focal length of 560 mm.
(f/7), designed for amateur astronomers who want a lightweight, easy-to-use instrument.
and capable of both visual and serious deep-sky astrophoto.
With its ED doublet, It offers excellent chromatic control, ideal for
enjoy nebulae, open clusters and large galaxies without the hassle.

An 80ED designed for the nomadic astronomer

The 80ED offers an excellent compromise between aperture, weight and size:

• 80 mm opening to find out more about the Moon, the planets and the deep sky.
• Focal length 560 mm (f/7) for a comfortable field of view, perfect with modern color cameras.
• Compact tube Approximately 404 mm with mist guard retracted and 505 mm extended.
• OTA weight 1.7 kg only, approx. 2 kg with collars and dovetail.
• 2-inch drain rear for diagonals, bends, correctors and wide-field accessories.

This featherweight design allows the bezel to be mounted on very compact frames. It fits easily into a
travel setup or a semi-fixed station, while leaving plenty of room for the camera, finder-guide and
the usual small accessories.

80 mm ED doublet optics for a clean, high-contrast field of view

The aim of 80ED is to ED doublet a low-dispersion glass lens combined with
an achromatic lens. This type of design is very popular with hobbyists, as it effectively limits
colorful bangs on the stars and high-contrast edges. The result is fine, well-shaped stars
This is a major asset for both imaging and high-magnification observation.

With its report f/7, the telescope remains fast enough for astrophotography without becoming
too demanding on collimation or tracking. It's a very healthy choice for a first tube dedicated to the
deep sky or as a complementary telescope to a larger-diameter instrument.

Mechanical design and ergonomics

The 80ED comes with all the essentials for a quick trip under the sky:

• Retractable mist guard to limit fogging and extraneous light, while keeping the tube compact for transport.
• Necklaces and dovetails (included in the manufacturer's gross weight), ready to be mounted on most common equatorial frames.
• Sortie arrière en 2″, This makes it easy to use wide-field eyepieces, curved eyepieces or a complete photographic optical train.
• Documentation The scope is supplied with a manual detailing diagrams and adjustment points.

Diagrams supplied by the manufacturer (dimensional diagrams, positions of locking screws, etc.),
optical path, speckle and longitudinal aberration diagrams) show a telescope designed
which supports modern sensors very well.

Astrophotography with the 80ED: wide field and dedicated accessories

80ED is particularly interesting for’wide-field astrophoto. Numerous images
reference models made with this bezel feature iconic objects such as :

• NGC 6960 (part of the Swan Veil),
• NGC 7000 (North America Nebula),
• NGC 6888 (Crescent Nebula),
• M8 (Lagoon Nebula),
• M16 (the «Pillars of Creation»),

as a 1.0x corrector (flattener) or a reducer 0.7x, specifically designed for
the 80ED. They flatten the field and, with the reducer, increase speed and useful field,
which is ideal for large nebulae with low surface brightness.

Whether with a ASI2600MC / QHY268C or a monochrome camera and filters,
the scope holds up very well: wide field, well-corrected stars and a setup that remains light on the frame.

For what kind of amateur astronomer?

The 80ED is particularly suitable for :

• For the enthusiast who wants to a versatile first instrument to observe and start imaging.
• To the astrophotographer a lightweight tube to put on a small nomadic frame.
• For those who already own a large diameter (Newton, Dobson, SC) and wish to a complementary bezel for wide fields and photography.
• For users who want a easy-to-balance setup, easy to transport and quick to warm up.

Thanks to its modest, but well exploited, aperture, the 80ED can scan large fields
in the Cygnus, the summer Milky Way or the Orion region, while remaining at home on the Moon
and planets with suitable eyepieces.

The 80ED in a complete setup

Integrated into a small, modern equatorial mount, equipped with a finder-guide and camera
dedicated Askar 80ED becomes an excellent setup core for imaging most large
nebulae and Milky Way regions. Its simple mechanics, versatile focal length and
ED make it a very pleasant instrument to live with for the amateur astronomer who wants to spend more time on his work.
time collecting photons than struggling with his equipment.
