Cassegrain Pro CC 154/1848 OTA Telescope

Stunning astronomical photographs with a professional telescope

This Cassegrain telescope was created to take astrophotographs of the highest quality and beauty. Images have more contrast and sharpness right to the edge. It is not surprising that professional observatories almost exclusively use this type of telescopes. Now this technique is also affordable for amateurs. Fancy taking your astrophotography to a professional level?

Summary of its advantages:

• Primary mirror with 94% reflection for clearer images than a standard telescope
• 8 scattered light baffles for greater contrast and sharpness
• Quartz mirror for a better image in the acclimatization phase: focus remains stable even during long nights of photography
• 2" and 1.25" Crayford focuser to avoid mirror displacement and achieve great rear focus. For astrophotography simply attach your SLR camera with the included 50mm and 25mm connectors
• Complete illumination with APS-C sensors or sensors up to 30 mm diameter

Who is this telescope designed for?

A Cassegrain telescope is a system for taking beautiful astronomical photographs that you can be proud of. Many types of telescopes are created to do everything from photography to visual observation. But that is not entirely true, everyone knows that there is no expert in everything. That's why this telescope was created especially for astrophotographers who like to photograph compact objects. We don't want a mediocre telescope to take mediocre photos. We want an instrument for astrophotography experts. This telescope is perfect for first-class sky photography.

Full illumination for most sensors

This Omegon Cassegrain telescope is ideal for photographing the starry sky. Connect cameras with sensors up to 30mm in diameter and benefit from full illumination without vignetting.

Why is a Cassegrain telescope better than a Schmidt-Cassegrain?

The primary mirror of the Omegon Cassegrain is parabolic and the secondary mirror is hyperbolic. For this reason there will be much fewer image aberrations: the image field is flatter, the coma is lower and the field sharpness is considerably higher. This means you will be able to take much more beautiful star photos and even see the finer details. Your astrophotos will be fascinating in every way.

What are the advantages of this telescope over a SC?

• Sharper image
• There are no lenses in the path of the light ray and, therefore, there is no need for an infrared filter for photographing the planets.
• Larger image field useful for photography, with fewer optical aberrations
• Less obstruction, which increases contrast
• No chromatic aberrations
• There are no ghosting images in the photographs.

Faster acclimatization process

Who wants to set up the telescope and then wait forever? With this telescope there will be no waiting. The parabolic quartz primary mirror hardly deforms during the cooling phase and is much more stable than Pyrex. This means that from the first minute the telescope shows you a crystal clear image.

Primary quartz mirror with 94% reflectivity

94% Enhanced Coating: This coating is special because every percentage point counts for clearer, higher contrast images. This mirror is the champion of its range, offering 6% more reflectivity than the standard fitted to most telescopes.

From now on you will be able to get clear images of faint deep sky objects.

Crayford: more than enough focus

Attach any accessory to your telescope and don't worry about focusing. With most cameras you can easily achieve a sharp image thanks to the large back focus of this telescope. You can also use a reducer or even binoculars.

8 scattered light deflectors

They provide more contrast for sharper images where more details can be seen.

No mirror shift

Ping-pong was a popular sport, but as a photographer trying to capture a planetary nebula in the eyepiece it's not that fun. The good news is that you no longer need to play ping-pong to take a good photo because, unlike an SC telescope, this Cassegrain has a fixed parabolic primary mirror. This way the object does not bounce around the eyepiece and stays where it should be.

What objects can you photograph?

Omegon's Cassegrain is unrivaled in the photography of compact objects in the Solar System or interstellar space. With its long focal length, even small nebulae can be reached. This telescope is great for:

• Craters of the Moon
• Planets
• Groups of distant galaxies, planetary nebulae
• Globular star clusters
