 Our guide to buying the right telescope for you

There are lots of telescopes available on the market, and for the beginner, selecting one can be a bewildering experience. Selecting a telescope for both astronomy and land viewing  will usually be a compromise. However, once you have decided on the telescope's main purpose, choosing one can become much easier.

If you have decided that your telescope will be used primarily for observing the night sky, the instrument required does not necessarily need to give a right side up image and is not required to focus on nearby objects. With the exception of the moon, planets and close star clusters, interesting night sky objects are faint, in fact most are very faint.

As a new observer you may be mainly interested in viewing the moon and planets, and if this is the case, a telescope with a small objective (primary mirror or lens) may be sufficient. However, most observers quickly graduate to galaxies, nebulae, globular clusters, open clusters etc. To view these objects you will require a telescope with the largest aperture that is possible for your circumstances, which will include things like cost, weight, portability, etc.

Newtonian reflector telescopes are a popular choice for astronomical use because they have the lowest cost per inch of aperture. Observation of faint deep sky objects, such as nebulae and galaxies, can be achieved at a relatively reasonable cost by reflectors having mirror diameters of 150 to 200mm (6 to 8 inches). Refractor telescopes are good for achieving high power and contrast when viewing the planets and the moon. They have a reputation of providing crisp, sharp-quality images. Since they are virtually maintenance free, they are easy to operate, but due to high costs for the large aperture scopes, most beginners will choose a Newtonian reflector as a first scope for all round astronomy.

Short-tube refractors are now another low cost option for beginners. Their smaller size makes them an excellent choice for a portable telescope and the beautiful wide-field star vistas which they provide, are great for learning your way around the night sky. Astronomy can be an expensive hobby, but it doesn't have to be.  There are ways to start enjoying the night sky without a lot of expensive equipment.  In fact you may aready own a pair of binoculars which is a great way to enjoy the sky. For a few dollars you can get a planisphere, a sort of rotatable star map that can show you the positions of the constellation and major stars in the sky for a given date and time. You can go to the public library or explore the internet for all kinds of information about astronomy and celestial events. There are pitfalls when starting out with astronomy. 

Many department and toy stores sell small refractors (usually 50-60mm) that advetise 500, 700 or 1000 POWER!  They have colorful space images on the box.  These should be avoided.  They can become an exercise in frustration, with their inadequate optics and shaky mounts. It's best to start simply. Find a local astronomy club if available.  Astronomy Clubs are great places to learn and to meet people who can answer your questions.  Also find a reputable store that sell telescopes.  Ask the folks at the astronomy clubs who they recommend. Start learning the sky with your eyes or with a pair of binoculars. 

As you start to learn about telescopes and astronomy, you'll discover that "Aperture" is more important than "Power" and a surprisingly large aperture telescope, like a "Dobsonian Telescope", can bought with relatively little expense. A telescope provides a very narrow view of the sky, typically around one degree and can provide a lot of aperture and magnification.  Binoculars can provide wider views of the sky, around 4-10 degress and have the advantages of using both eyes.

Let's Have A Look At The Various Types Of Telescopes Available

———————————————————————————————————————

 
ReflectorDiagram

REFLECTOR The second method of focussing light is to reflect the rays off of the surface of a curved mirror, producing a type of telescope called a reflector. The most common reflectors in use today are called Newtonians because this design was pioneered by Isaac Newton.

A mirror is made by coating the front surface of a concave piece of glass with a reflecting material. Light rays entering the telescope reflect off of the mirror and since they never pass through the glass no false colour is produced.

The surface of the mirror of a high focal ratio reflector can be shaped or figured to that of the surface of a sphere. This works for small reflectors and those with focal ratios of f9 or higher. However, with large reflectors and those with focal ratios of f8 or lower, these spherical mirrors do not bring all of the light rays to the same focal point. The rays from the mirror’s perimeter are focussed at a different point from it’s centre, resulting in an image which lacks contrast due to spherical aberration.

To overcome this defect, mirror surfaces are shaped during polishing to a paraboloidal shape which focusses all of the light rays to the same point. Since the light rays are reflected back up the optical tube by the primary mirror, they must be redirected in order to be viewed. A secondary mirror, which has a flat surface is mounted at a 45 degree angle in the centre of the tube to reflect the rays to the focal point. The secondary is usually oval in shape because this presents a circular shape when viewed from a 45 degree angle. Obstructions, such as secondary mirrors, have a limited visual effect when placed in the path of the light entering the telescope.

They modify the diffraction patterns, which can cause very minute loss of contrast, and they reduce the amount of light reaching the focal point. However, they are not seen in the focussed image presented through the eyepiece. Since the eyepiece is near the front of the tube, reflectors can be mounted lower to the ground giving more convenient viewing and greater stability. Only two surfaces need to be shaped, polished and coated and these can be tested separately. This makes them less expensive to produce than other telescope designs. On the negative side, a long optical tube Newtonian on a German equatorial mount can be more susceptible to wind vibrations than shorter designs. Collimation of both mirrors is part of the regular maintenance for reflectors.

 
RefractorDiagram REFRACTORS There are three basic ways to bring light rays to a focal point. The earliest method used by telescope makers, was to bend the rays by passing them through one or more pieces of glass which had curved, polished surfaces. This method produces a type of telescope called a refractor. Refractors have several advantages over other designs. They are enclosed so that dust and moisture doesn’t enter the optical tube.
They have fixed optics so that they don’t require routine collimation, which means that the optics don’t have to be aligned by the user.They do not have a central obstruction, which reduces the amount of light entering the tube and causes an alteration of the diffraction pattern. The resulting high-contrast, fine-resolution images produced are considered ideal for planetary viewing. A problem with refractors is that since many wavelengths of light are passing through glass, the uneven bending of the rays causes false colour, around bright objects. This must be counteracted with additional lenses and special glass. Since at least four lens surfaces usually have to be very accurately shaped, polished and coated, they are more expensive to produce than other telescope designs.
 
CassegrainDiagram CASSEGRAIN A third group of telescopes, called Cassegrain, are hybrids of the two previous methods. Cassegrain telescopes use a combination of both mirrors and lenses to manipulate and focus the light rays. Examples of these are the Schmidt-Cassegrain, and the Maksutov-Cassegrain.
Schmidt-Cassegrain telescopes use a thin aspherical corrector plate, which is a lens carefully matched to the primary concave mirror to correct for spherical aberration. Parallel light rays enter the telescope through the corrector plate and are then reflected by the primary mirror to a convex secondary mirror which is mounted inside the focal point and concentric with the corrector plate. The secondary mirror reflects the rays back down the tube and through a hole in the centre of the primary. The eyepiece can be placed directly behind the primary mirror or a diagonal can be used to change the angle at which the image is viewed. Focussing may be achieved by moving the primary mirror or by moving the eyepiece.

Telescopes can cost upwards of hundreds of dollars. So, before you buy, shouldn't you get informed?

Maksutov-Cassegrain telescopes are similar to the Schmidt-Cassegrains. They also have a corrector plate to remove spherical aberration, but they use a thick, meniscus lens instead of a Schmidt lens. Light enters through the concave side of the corrector plate and the primary mirror reflects it back up the tube to the secondary which is often a mirrored spot on the convex side of the corrector plate. As with the Schmidt-Cassegrain, the light rays are reflected through a hole in the primary to reach the eyepiece This design is easier to produce than the Schmidt-Cassegrain, but the thicker corrector plate makes it heavier.

The Maksutov-Cassegrain telescope was developed in the 1940’s by several different inventors of slightly varying designs. Most commercial Maksutov telescopes available have similar optical designs. The main advantage of this design is that, because the light path is folded back on itself, it provides a very portable, short physical length telescope with a long focal length. Cr Tasco

ASTRO DAVE RECOMMENDS……..

A Dave-headshot-reverseOk, you're new to all this and you just want to buy a telescope to poke around the sky. You don't want confusion – heck, all this is confusing enough if you've got this far! You don't want to get ripped off, or worse, pay too much for a telescope with features you'll never use,  right? Look, I''ve been there, it's worse than trying to find a good used car with no mechanical knowledge. SO, with all this in mind I've taken the bull by the horns and put together this 'recommened list' of telescopes to suit most levels and most age groups.

Remember, this is just a guide, it's impossible to tailor one specifically for you, but we'll come mighty close! There are hundreds of telescopes out there, BUT it's a guide based on 40 years of experience and 40 years of consoling many Dads who've come to me after Xmas with an el-cheapo scope that won't work, wobbles in the breeze and has lousy optics. (it's usually a department store special) and he wants me to "fix it."

Uh Uh! Can't do! Dad's dejected because he's tried to do the right thing, the kid's lip is on the ground and the scope ends up in a garage sale a few years later selling for a fraction of what it cost. The hardest thing to sell is a used telescope! 

Special Offer – Not Available In Stores!

Now, all these scopes are available from me and delivery is quick. Full warranties and guarantees apply PLUS you get FREE membership to my 'advice/help' line where I'll answer your astro questions or supply good advice. A FREE newsletter is alo available if you want it (sign up on my home page) and every order gets a FREE astronomy DVD (while stocks last). NB/ As a lot of these telescopes are imported prices are occasionally subject to change due to exchange rate variations. I'll advise if this is the case .OK. What are we waiting for .. let's go.

Skywatcher 70 x 900 EQ1 (and Upgrade to 80mm)

A great beginners telescope. I love this scope – always have!

CAPRICORN-70-(EQ2).jpg (500×500)Super popular and good quality achromatic 70mm x 900mm refractor on the EQ1 equatorial mount which has adjustable height aluminium tripod legs.  Our most popular small refractor! Optically, far superior to all el-cheapo 60mm refractors and its EQ1 mount operates very smoothly, too. The Skywatcher GreatStart SW 70AR-EQ2 70mm  Refractor telescope provides a vastly easier way to keep objects centered in the eyepiece.

  At higher powers sky objects can drift across the telescopic field in well under a minute due to the Earth's rotation.  With slow-motion controls higher powers can be used more effectively.  The dual slow-motion controls allow smooth, incredibly fine movement, …impossible to achieve by hand . The 70mm is supplied with what is called an equatorial mount that has slow-motion controls on each axis as standard equipment. 

The equatorial mount allows the telescope to follow objects in their natural arcing motion across the sky from East to West.  These controls are immensely useful in helping keep planets and stars centered in the eyepiece while observing.  By the way, premium quality t eyepieces are standard equipment with this telescope!

It shows clearly and sharply the rings of Saturn, the cloud belts of Jupiter and craters on the Moon by the hundreds.  For land viewing the optics provide tack sharp detail in distant landmarks, nature, or points of interest across the urban panorama.  Stability of the mount and tripod upon which the optics are placed is of paramount importance.  It matters big time!  Cheap flexible mounts and rickety tripods act like tuning forks transferring vibration to the eyepiece.  Such circumstances deprive the viewer of a steady view.  Images dance around in the eyepiece in a distracting manner.

Skywatcher 102 x 500 AZ3

Rich field achromatic 102mm x 500mm refractor on the heavy-duty AZ3 alt-azimuth mount with adjustablre height aluminium tripod legs.

This Sky-Watcher 102mm (4") f/5 telescope is a two-element, air-spaced, fully multi-coated objective, achromatic refractor, which can give exciting "rich field" astronomical views.  It can provide excellent vistas of star fields, clusters, nebulae, galaxies, planets, the Moon and (with correct filtering or by projection) the Sun. 

It is also a fine terrestrial telescope when mounted on an alt-azimuth mount or a photographic tripod. Crisp images at a reasonable price make it an excellent beginner's "first telescope", or a great travelling telescope for a more advanced observer.  Similar to the popular 80mm f/5 refractor, this larger aperture model has more light collecting power at the same focal ratio and accepts 2" diagonals for awesome wide field views, while only a small amount to chromatic aberration and weight.

Weighing about 3kg.  (6.5lbs.) the optical tube assembly is readily carried and with a compressed length of approximately 50cm (21.7") it is easily transported. Being a refractor, it is quick and easy to set up and the low- maintenance, enclosed optics come fully collimated from the factory.  The optical tube assembly comes with "tube-mounting rings".  These hinge open to allow easy installation of the optical tube and the locks can be loosened during use to allow tube rotation and balancing.  Mounting the telescope on an alt-azimuth or an equatorial mount is quick and simple with the appropriate mounting plate.

The 25mm and 9mm Plossl eyepieces provided as standard, will provide magnifications of x48 and x133 respectively. These translate to fields of view of 63 and 23 minutes of arc, or approximately 2.1 times the diameter of the full Moon and 75% of the diameter of the full Moon respectively.

The telescope will provide excellent viewing of the Moon and planets; sharp views are helped by the small secondary mirror (55mm) and thin struts on the supporting spider. The Cassini division in the rings of Saturn or the great red spot on Jupiter are easily visible. Brighter nebulae and globular clusters are easily seen, and from sites with darker skies, many galaxies and fainter objects will be available.

The limiting magnitude for discrete stellar objects will typically be in the range magnitude 12.5 – 13.0. The GSO 680 comes with a spring friction system.
