Schmidt Cassegrain

1. Celestron 6″ Schmidt Cassegrain Optical Tube

This is the cheapest of the 5 telescopes that we reviewed. 

Even so, like most Schmidt Cassegrain scopes, it still does come at quite a hefty price.  

The telescope features a 6″ Schmidt Cassegrain Optical Tube Assembly and an Aluminum Optical Tube. 

It has StarBright XLT coatings, which are the premium choice in this industry. 

This innovative coating is made up of three different layers that greatly increase contrast and light transmission. 

We were able to view details on the moon in great detail, really exciting the kids! The telescope has a 1500mm focal length and a 25mm eyepiece with 60x magnification. 

This is a great telescope for a beginner who wants to start with a professional model and not waste time on ‘cheapies.’

Schmidt Cassegrain vs. Maksutov Cassegrain telescope?

Schmidt Cassegrain

Schmidt Cassegrains are high-level all-purpose telescopes, ideal for viewing the moon, planets, and deep-sky objects. They are also ideal for astrophotography, using everyday DSLR cameras. Most come with computerized GoTo mounts and motorized object tracking. On the con side, expect to pay more than you would for a Dobsonian-type telescope

Maksutov Cassegrain

Maksutov-Cassegrain is a great telescope with a shorter tube. They are more suited for objects that require high magnification such as planets, the Moon, double stars, nebulae, and global clusters. They are compact, rugged, and easy to transport. In general, models have a higher magnification than other types of telescopes. Many models are specifically made for use in harsh environments, industrial sites, and military operations.


Both types are built with a catadioptric design that combines a mirror at the back and a lens at the front. This design causes the light path to ‘fold,’ allowing the tube to be shorter. This design also corrects a common problem known as the coma. Coma means that images not in the center of the lens tend to look distorted or wedge-shaped. 


The main difference lies in the design of the mirrors. Schmidt scopes have a thin complex-shaped corrector lens. Maksutov scopes have a thick spherical corrector lens. The secondary mirror in a Schmidt is a mirror, while in the Maksutov, it is not a mirror; it is an aluminized small spot. Schmidt’s usually have bigger apertures than the Maksutovs.

The good and bad of SCT (Schmidt Cassegrain)

Like most high-end electronic devices, telescopes come with pros and cons. When considering buying a Schmidt Cassegrain, the first issue is the price. You will expect to pay more than other brands. But, this will certainly be a telescope that will last a lifetime. The cost is higher due to the correcting lens, motorized tracking, and the innovative GoTo functionality of the mount. 

Schmidt telescopes offer exceptional clarity, color, and crisps views. Most come with computerized GoTo mounts that track objects as they move across the sky. Many have built-in GPS technology. This allows the scope to plot longitude and latitude, time, and date without you having to enter the data manually.

When it comes to lenses, you have a choice of smaller models with a 150mm (6 inch) lens. Most offer lenses of 200mm (8 inches). These scopes have a design that allows the light to ‘fold.’ This means that the tubes are shorter and more compact. 

Computerized telescopes come with database software of celestial objects, often as many as 40000. By simply focusing on a few key objects, the telescope will find what you want and provide all the info you need. What a great way to easily learn about the night skies! View the surface of the moon, planets, stars, galaxies, star clusters, solar system objects, and nebulae. 

If you want to try your hand at astrophotography, you can connect a simple DSLR camera or webcam to the scope. 

Although the scopes themselves are compact, the mounts are usually quite heavy. This may be an issue if you plan on traveling with your scope

What can you observe with a Schmidt Cassegrain?

When it comes to stargazing, the size and strength of your telescope will make a difference. Schmidt Cassegrains are at the upper end of the scale, so you will get amazing views with all the models.

There are 2 main issues you may want to consider, and it is related to price. Scopes in the lower price range have an aperture of 150mm (6 inches). Those at the higher end have an aperture of 200mm (8inches) or more. The larger the aperture, the more light the scope will collect. This allows clearer viewing of deep-sky objects and those that are further away.

Magnification also plays a part. Most Schmidt scopes offer a magnification of between 50x to 80x. The larger the magnification, the more you will see. But, keep in mind that very high magnifications can also cause blurring of objects.

  • 150mm (6 inch) Aperture. Use this scope to view craters on the moon. Planetary details like textures, color, and surrounding clouds are apparent. You will see details of nebulae and star clusters.
  • 200mm (8 inch) Aperture. More details become apparent. See more detail of the rings of Saturn, the separation of double stars, and precise details of deep-sky objects.
  • 280mm (11 inch) Aperture. Now you are able to view sharper and clearer images. Even with light pollution in the atmosphere, you will see faint nebulae that are not visible with smaller scopes.

How to choose the best Schmidt Cassegrain telescope?


Schmidt Cassegrain telescopes offer apertures of 150mm, 200mm, 280mm, and larger. All give stunning, clear views with great color and detail. Your choice depends on your budget. 

Field of view

This is the circle of sky visible through the eyepiece. The higher the magnification, the smaller the field of view becomes. Schmidt Cassegrain scopes offer a field of view of between 0.70 and 1.00 degrees, ideal for the planet and deep-sky viewing. 


Telescopes with magnifications of 50x to 80x are ideal for everyday viewing. You can alter the magnification by attaching different lenses. Some scopes come with a kit of lenses of different magnifications. Remember that very high magnifications can distort your images. 

Focal length

All-round telescopes have focal lengths of around 1000mm to 1500mm. The shorter the length, the more suited it is to a wide field view. To view objects that are further away, you need a longer focal length.


Most Schmidt Cassegrain telescopes come with GoTo mounts that offer computerized tracking. If your model does not have a mount, buy one that is lightweight but sturdy. You want to be able to transport it easily. But, you don’t want your scope toppling over while viewing. 


If you have a permanent place for your telescope, weight is not an issue. For portability, the lighter the scope is, the easier it is to take along with you. 


Schmidt Cassegrain telescopes have a distinct compact size. This allows you to travel with your scope and not lose out on exceptional quality.
