Omegon Telescope ProNewton N 153/900 OTA

Omegon Pro Newtonian – How to start your astronomy with a real boost

Astrophotography or visual observing? This is not a relevant question for this OTA – it works really well for both. This series thrives on the elements that make an OTA a powerful tool for astronomy.

Enjoy sharply etched lunar craters, planets showing a wealth of detail, and deep sky objects that simply look brighter than through standard telescopes. The Omegon Pro Newtonian does not do things by halves – the workmanship and quality are first rate, ensuring everything works a treat for your exploration of the night sky.

The advantages in a nutshell

• excellently engineered OTA – enjoy your observing for many years to come
• BK-7 main mirror with 94% reflection – brighter images and much more contrast than a standard mirror
• 2″ Crayford focuser – smooth focusing so you can easily find the exact point of focus
• great back focus – connect your SLR camera or any other cameral
• easy set-up – the prism system means the OTA will fits onto any mounts using a Synta/Vixen/Skywatcher/Celestron system

High quality metal OTA with excellent processing

The telescope’s OTA offers you a sound introduction to a fascinating hobby. No cheap plastic, but metal together with excellent workmanship. This is an important prerequisite in the world of telescopes as it ensures you will continue enjoying your observing for many years to come.

BK7 glass primary mirror

The centrepiece is the main mirror, which is made from BK7 glass. In contrast to ‘ordinary’ glass, this offers a more stable shape during the cool-down phase, and that means a better image, even if the OTA has not yet completely equalised to the outside temperature.

Enhanced coating – 94% reflection for bright pictures

When you dive into the depths of space, you can see objects with your telescope that would never be visible to the unaided naked eye. What is important here is the aperture and the main mirror – with this telescope boasting 94% reflection. Enjoy extraordinary, high contrast images – letting you make out even the fainter deep sky objects.

2″ Crayford focuser for the sharpness you need

The single-speed 2″Crayford focuser lets you easily focus with any eyepiece you want. The ball-bearing design enables feather-light and precise location of the exact point of focus possible.

Astrophotography – suitable for your SLR camera

You can connect your camera to take your own astronomy photos. Telescopes are not always that easy here, but this focuser gives you enough back focus. What does that mean? – you can achieve exact focus for taking the astronomy photos of your dreams even using a large DSLR camera.

Easy assembly – compatible with most mounts

A 33.5 centimetre long Vixen-style prism rail is the base for almost any sensible mount. It is the ultimate standard size for most higher-quality mounts. The great thing is that you can attach your OTA and bring it to perfect balance in just a few seconds.

Thin spider and maximum contrast

Astronomers already know that a ‘spider’ here has nothing to do with the creepy-crawly which lives in your cellar. The secondary mirror spider holds the secondary mirror in position. The struts in this telescope’s spider are only a few millimetres thick. The result is that the contrast is impressive.

Our tip – All around, a high quality OTA for getting started or for upgrading in astronomy.

Your choice – an f/5 or f/6 OTA?

This telescope is available in two versions – with aperture ratios of f/5 or f/6. But what is the difference? Which one should you go for?

The aperture ratio is the ratio of aperture to focal length and affects the telescope’s characterisics.

Characteristics of an f/5

• shorter length – the telescope is slightly more compact and is also suitable for smaller mounts
• shorter focal length – means shorter exposure times and a wider field of view for astrophotography
• recommended for ambitious beginners, advanced observers and astrophotographers

Characteristics of an f/6

• longer focal length – achieves higher magnifications with eyepieces. Ideal for planets and planetary nebulae.
• budget eyepieces can also provide a good image
• the telescope is easier to adjust overall and is more forgiving of slight adjustment errors. This means that you can achieve a good contrast with planets.
• recommendation for beginners or visual observers who want to easily zoom in
