EXPLORE SCIENTIFIC 100° Ar Eyepiece 14mm (2") (Refurbished)

Take your first steps into the wonderful world of astronomy – with this complete set consisting of an astronomical Maksutov-Cassegrain telescope with 100 mm aperture and 1400 mm focal length, equatorial EQ-3 mount, tripod and extensive accessories. The special feature of this beginner’s telescope: Due to the high contrast, you can start your journey to the stars wherever you like – even in the middle of a brightly lit city. And yet the extremely compact telescope takes up very little space on balconies, terraces and the like. The system is easy to handle and therefore perfect for beginners. The optics show especially the Moon and planets at their best. Ideal for all travel-loving amateur astronomers: due to its compact design, the telescope is also perfectly suitable as a travel telescope. Compact high-quality optics for beginners – the telescope Powerful optics with a long focal length in a very compact design for easy transport – that is what Maksutov-Cassegrain telescopes offer. The design principle: The optics combine mirrors and lenses with very good imaging properties. With the 100 mm aperture, the BRESSER Messier MC-100/1400 already collects a lot of light and offers a good resolution. Due to the extremely large focal ratio of 1 to 14 (F/14), which results from the 100 mm aperture and the 1400 mm focal length, you enjoy a very sharp image with excellent contrast. This means that the telescope is an absolute specialist when it comes to exploring the Moon, Sun and planets. But you can also look forward to observing many deep-sky objects through your telescope for beginners. Admire open star clusters, globular clusters and so-called planetary nebulae such as the impressive Dumbbell Nebula M27. Really sharp images with up to 200x magnification – no problem thanks to the resolution of the 100 mm aperture! From a purely technical point of view, even more is possible in terms of magnification. However, increasing magnification often results in a loss of image sharpness. Moreover, the telescope is not the only factor when it comes to the question of how high you can magnify. The air turbulence in the atmosphere (seeing conditions) also plays an important role. Good foundation for your space exploration – mount and tripod While you enjoy the view of the sky, your Maksutov-Cassegrain telescope is perfectly mounted on the height-adjustable aluminium tripod with equatorial EQ-3 mount. The equatorial design has a decisive advantage: Unlike azimuthal models, you have to compensate for the movement of the celestial bodies on just one axis. To do this, you align this particular axis of the equatorial mount parallel to the Earth's axis by pointing it approximately at the polar star – also known as "alignment". Thanks to the two flexible shafts with fine adjustment, tracking and adjusting the telescope is extremely comfortable and precise. The storage plate between the tripod legs keeps your astronomy accessories ready for any exciting discovery.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! Complete equipment for your start in astronomy – the accessories Unpack and get started straight away – with the extensive accessories, you can immediately set off on your own exploration trip through our solar system. The LED viewfinder allows you to find celestial objects easily and align the beginner's telescope precisely. For this purpose, the viewfinder is mounted parallel to the actual telescope. And this is how it works: Inside, a red dot is projected onto a small ground-glass screen. When you then look through the LED viewfinder, this dot appears to be floating in front of the sky – exactly where your telescope is pointing. The eyepiece included in the astronomy set is impressive as well. The 26 mm Plössl eyepiece offers a 54x magnification and very good imaging properties. Simple upgrade: Because the tube diameter of 31.7 mm (1.25 inch) corresponds to an international standard for all manufacturers, you can easily extend your astronomy starter set with additional eyepieces. This way you can admire your favourite sights in other magnifications as well. Especially when the telescope is pointed vertically into the sky, the 90-degree star diagonal mirror proves to be very helpful. It allows you to look into the telescope comfortably from the side, even at unfavourable viewing angles. Fascination Sun – with the Maksutov-Cassegrain beginner's telescope, you can take a close and safe look at our own star. Simply attach the solar filter to the aperture. The sight of sunspots and granulation on the Sun is guaranteed to amaze you! ATTENTION: Never point the telescope at the Sun without the solar filter! Capturing breathtaking astronomy moments is easier than ever. Simply place your mobile phone with the smartphone adapter on the eyepiece, take pictures and share the most beautiful snapshots of the Sun, Moon etc. immediately.

One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects bejond the solar systems enourmously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artifical light. The Explore Scientific H-beta filter uses a characteristic property of the so called emmission nebulae. Those objekcts glow in special colors, the so called emmission lines. Those emmission lines are linked to chemical elements - in this case hydrogen. The Explore Scientific H-beta nebula filter blocks all other colors (and thereby nearly all of the artificial light) and only the emmission line of the hydrogen can pass the filter. The result is astonoishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburbian skies for example the horsehead nebula is almost not visible with a 300mm telescope. By using this filter you can see the nebula and its structures without problems. A must for every visual observer. The Explore Scientific nebula filters come with a individual test certificate - your guarantee to receive a premium filter.

These ultra-wide angle eyepieces played a critical role in the military for aiming at targets, and their long eye-relief counterparts helped reduce eye injury from recoil.Each 100° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus. This also maximizes the life of the internal coatings.To make sure, every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes.All 100° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.
