That is normal. Finder scopes are only used to make objects easy to locate. The image orientation does not matter for observation.

  • Alt-azimuth: easy to use, moves horizontally and vertically
  • Equatorial: enables precise tracking of objects with only one axis – ideal for high magnifications and astrophotography

  • Moon: from 30 mm
  • Planets: from 100 mm
  • Deep sky: from 150 mm

Product information "BRESSER Messier MC-90/1250 EQ3 Maksutov-Cassegrain Telescope with Smartphone Adapter & Solar Filter"

Taking off to the stars from your own balcony – with this complete astronomy set that is easily done. The compact Maksutov-Cassegrain telescope with 90 mm aperture and 1250 mm focal length fits everywhere. And thanks to the high contrast, you will be amazed by fascinating insights into outer space even while standing in the brightly lit city. Especially the Sun, Moon and planets look great through the high-quality optics of the beginner's telescope. The set includes everything you need for successful sky observation: an astronomical Maksutov-Cassegrain telescope with 90 mm aperture and 1250 mm focal length, an equatorial EQ-3 mount, a tripod and extensive accessories. The system impresses with its simple operation, which makes life easier for astronomy beginners in particular. Thanks to its compact dimensions, the powerful telescope is also ideal as a travel telescope for more experienced stargazers.

A great combination – the telescope
The decisive advantage of the Maksutov-Cassegrain construction: the powerful optics have a long focal length, but can still be easily transported due to their very compact design. The recipe for success is the combined optics of mirrors and lenses with very good imaging properties.
The 90 mm aperture admits a lot of light into the beginner's telescope and thus ensures a good resolution. In addition, 90 mm aperture and 1250 mm focal length result in an extremely large focal ratio (ratio of aperture to focal length) of 1 to 13.9 (F/13.9). The impressive result: a very sharp image with excellent contrast. Moon, Sun and planets – especially the celestial bodies in our immediate vicinity are more than worth a look through the BRESSER Messier MC-90/1250 Maksutov-Cassegrain telescope for beginners. But various deep-sky objects are also a sight to behold: go on a discovery tour through space and marvel at open star clusters, globular clusters and so-called planetary nebulae such as the fascinating Dumbbell Nebula M27. Thanks to the resolution of the 90 mm aperture, you can enjoy really sharp images at magnifications of up to about 180x. The technology allows more, but you have to reckon with blurriness at higher magnifications. In addition to your telescope, the air turbulence in the atmosphere (seeing conditions) also determines how much you can actually magnify.

Your astronomy start is on a firm footing – mount and tripod
The beginner's telescope comes with a height-adjustable aluminium tripod and an equatorial EQ-3 mount – the perfect basis for your exploration of the universe. The special feature of the equatorial mount: you only need to compensate for the movement of the celestial bodies on one axis instead of two. You simply align this axis parallel to the Earth's axis by pointing it approximately at the polar star – a procedure also known as "alignment". For sensitive and comfortable adjustment and tracking, the mount is also equipped with two flexible shafts with fine adjustment. Always ready to hand for every celestial highlight – to this end, your accessories will find their place on the storage plate between the tripod legs.

Keep track of things automatically: For this telescope’s equatorial EQ-3 mount, the tracking motor with item number 4951400 is available as an optional accessory. This eliminates the need to manually track a celestial object set in the telescope. When this motor is installed at the mount, it automatically tracks the celestial object, keeping it in the field of view of the eyepiece. This makes observing the night sky even more comfortable!

Everything for stunning stargazing – the accessories
With the complete astronomy set, your observations will be under a lucky star. The LED viewfinder, which is easily mounted parallel to the telescope, allows you to keep an overview of the night sky. For this purpose, a red dot is projected onto a small ground-glass screen inside the viewfinder. This dot appears to be floating in front of the sky when you look through the viewfinder. And it does so exactly where the aperture of the telescope is pointing. Thus, precise alignment and finding celestial objects becomes super simple!

The 26 mm Plössl eyepiece shows greatness in every respect: With it, you can enjoy 48x magnification with very good imaging properties on this telescope. Would you like to look even closer? Then extend your set with additional eyepieces. Because the socket diameter of 31.7 mm (1.25 inch) corresponds to an international and manufacturer-independent standard, you have a wide choice.

A comfortable view into the beginner's telescope at all times – this is ensured by the built-in 90-degree star diagonal mirror. So you can look in from the side with ease, even if your telescope is pointing vertically upwards into the sky.

It's not just the night sky that fascinates astronomers with beautiful views. Set out with the solar filter to explore our nearest star. Sunspots and granulation on the Sun are guaranteed to amaze you.
ATTENTION: Never point the telescope at the Sun without the solar filter!

What could be better than reliving unforgettable moments? With the smartphone adapter, the beginner's telescope becomes a giant lens for your mobile phone in no time. So you can easily capture and share your favourite moments with the Moon, Sun etc.
