Professional telescopes – Buying guide & Comparison

 

If you’re short on time and you just want to find the best professional telescope, this short paragraph should help you get exactly the model you need. We have collected enough information to enable us to compare various products based on actual owner feedback, ratings and reviews in expert review sites and product surveys. According to our findings/research, the Meade Instruments LX90-ACF 1210-90-03 is the best because of its superior highly technological optical design that delivers a flatter and interference-free field of view with precision imaging right to the edge of the field, easily challenging what more expensive models can give you without costing as much. Its integrated Sony GPS sensor determines the date, time and location of observation as soon as the telescope is switched on. This intelligent professional scope boasts genuine Easy Align technology that selects two stars of alignment for you and positions them at the exact spot on the viewfinder. If the Meade Instruments LX90-ACF 1210-90-03 is unavailable, your second option should be the Meade Instruments 1205-05-03.

 

Nothing quite works like a professional telescope when making scientific observations of the celestial objects in the night sky. The low price of a department store-bought telescope may be tempting, but in terms of craftsmanship and quality components, a premium quality model is always worth the money spent on it. What makes a product of this type the best professional telescope to buy?

 

The best advanced telescopes are designed with high apertures

Because telescope manufacturers make magnification a big thing, you will often see the packaging of their products highlighting this seemingly essential component. However, an informed consumer should be aware that 600x magnification and similar expressions do not reflect a telescope’s overall capacity to enable viewing of objects clearly and efficiently. Aperture, which is the dimension or size of the lens or mirror, is a primary consideration in this type of instrument. Just like a camera’s number of megapixels does not demonstrate its full capability, neither does magnification play a huge role. There are included items in the package that will enhance magnification, such as Barlow lenses or the eyepieces themselves.

In cameras, you won’t be able to crowd that many pixels in the printed image as you may end up with a blurred or grainy photo. For telescopes, the image quality will only be as good as the aperture size. A progressively large aperture is what you need for viewing faint deep sky objects with great detail. A large aperture also provides more potentials for viewing. If you have a telescope that’s too small with an extremely large magnification, you won’t see objects as clearly as you should. It is the aperture that indicates the power of the scope, not the magnification.

Moreover, while small scopes deliver clear images during perfect conditions even to a maximum of 100x per inch of aperture, you will no longer be able to see detail at 50x per inch. Large scopes that are affected by air currents may deliver a maximum useful magnification at 20x or 30x per inch. Technically, you may get a maximum magnification of 200x from a 3- or 4-inch refractor, but you will rarely have any size scope that can benefit from over twice or thrice that magnification.

 

Consider the products in the best professional telescope reviews that are of the type you feel comfortable working with

A dioptric or refractor telescope is the most common type of device that customers go for. Having a thin and long tube through which light travels straight from the objective lens at the front to the eyepiece at the rear, refractors are easy to use and offer dependable performance because of their simple design. They also need no maintenance and are useful both for terrestrial and celestial exploration applications. Refractor telescopes deliver high contrast images because they don’t make use of secondary mirrors, and neither do they have diagonal obstruction as an issue. For decent color correction, look for refractors with an achromatic design. Superior color correction is delivered by extra-low dispersion (ED), fluorite and apochromatic refractors. The sealed optical assembly of a refractor effectively prevents the degradation of images due to air currents. This design also ensures protection to the scope optics. Easy use is supported by the permanently aligned and mounted objective lens.

Reflector telescopes, otherwise called catoptrics, generally utilize a concave parabolic primary mirror to collect and focus light onto the secondary mirror that has a flat, diagonal design. The reflected image is relayed through an opening at the side of the primary tube then on to the eyepiece. Reflector telescopes work through mirrors that have less cost to produce than lenses with medium to large apertures in catadioptrics and refractors, thereby delivering performance at low cost per inch of aperture. Moreover, while boasting portable and compact profiles, they feature the best design that enables the examination of faint celestial objects such as star clusters, nebulae and distant galaxies. For viewing of the Moon and the planets, reflectors offer reliability. They also work well for deep sky astrophotography, which can be attributed to their ability to block optical aberrations for spectacular views of astoundingly brilliant objects. The reflected design also prevents extreme loss of light.

Employing a combination of mirrors and lenses on its optical design, a catadioptric telescope allows light through a thin, aspheric Schmidt correcting lens. The light strikes the spherical primary mirror and then bounces back up to the optical tube. Intercepted by a small secondary mirror, the reflected light then goes back out through an opening in the rear of the instrument and is generated as an image on the eyepiece. The two most common designs of this type are the Maksutov-Cassegrain and the Schmidt-Cassegrain. Catadioptric scopes have the most modern design and are popular throughout the world. You can select from 3.5-inch and larger apertures. Catadioptrics can be used for binary star, lunar and planetary observations in addition to terrestrial viewing or photography thanks to their exceptional optics that are able to provide images over wide fields.

The best semi-professional telescope should be supported on a strong and stable mount

To ensure easy and convenient viewing of celestial objects, a telescope first needs to be pointed in the right direction and should stay steady. Your hands work well to do this with binoculars, which can also be supported on a tripod for greater stability and to obtain better views. Altitude azimuth (altazimuth or simply alt-az) mounts come with a basic frame. Dobsonian mounts, with their wooden construction, are examples of this type of mount.

The celestial objects under observation can seem to be in constant movement across the sky. This is due to the revolution of our planet on its axis. With a motorized equatorial mount, this movement is amply compensated. However, equatorial mounts are not easy for everybody to use, especially for beginners. Steer clear of telescopes with extremely cheap equatorial mounts because they generally have inferior gears that will greatly disappoint. If you intend to do deep sky astrophotography, you will need a scope with a top notch equatorial mount. For effortless finding of celestial objects, you may want to check out computerized and GPS-assisted mounts.
