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.

The Explore Scientific Two Room Pop-Up Observatory is a useful weatherproof tent that protects your valuable equipment from wind, dew, rain and dust. Most amateur astronomers and astrophotographers dream of having an observatory to keep dust, dew and wind away from their telescope and to shield disturbing stray light from their telescope's optics. But for many astronomers, an observatory is only a dream because of the cost of a roll-roof building or an observatory dome. There is also the problem that an observatory building needs a permanent location that is suitable for an observatory. Portable, quick to set up and inexpensive A good solution is a portable observatory tent. Compared to their fixed counterparts, a tent is extremely inexpensive and can be set up almost anywhere there is a flat surface and a clear view of the sky. However, setting up a portable observatory tent can also be a hassle. No one wants to waste their valuable observing time reading complex instructions while trying to figure out which pole goes where. For this reason, we have used a sturdy pop-up design. Setting up the EXPLORE SCIENTIFIC Pop-Up Observatory can be done in a matter of minutes. By releasing a retaining strap, the complete tent unfolds from its packaging in just a few seconds. You really don't need to do anything other than connect the two observatory rooms with a Velcro seam and attach it to the ground. Thanks to this simple design, the EXPLORE SCIENTIFIC Pop-Up Observatory can be set up and taken down in just a few minutes, giving you plenty of time to enjoy your astronomy weekend. Plenty of space for your equipment and super compact when folded up. With just under 5 square metres of total space and 1.52 metre high side walls, coupled with 1.83 metre high windscreens, the EXPLORE SCIENTIFIC Pop-Up Observatory allows you to set up your computer equipment in one room and the telescope in the other, or set up two complete telescope systems. Each room is 152 by 152 centimetres. Mobile observatory with compact transport dimensions In addition to being easy to set up and take down, another advantage of the pop-up design is that it is travel-friendly, as it is light and easy to stow away. The entire observatory tent folds down to a package 70 centimetres in diameter and 10 centimetres thick. This allows it to be transported in a small car or even on a flight for distant expeditions. And apart from the fact that it allows you to go to your favourite observing site at any time, portable observatory tents are usually the first choice for astronomers and astrophotographers attending star party events.  Advanced materials provide optimal protection and durability However, the fact that the EXPLORE SCIENTIFIC Pop-Up Observatory is lightweight and easy to store and set up doesn't mean it can't withstand bad weather conditions. The Black-Out coated polyamide material is waterproof and offers excellent UV protection. This guarantees reliable protection for your equipment as well as long-lasting durability of the observatory tent. Large doors for convenient use The doors to enter the observatory tent and pass through the attached rooms are very generously sized at 102 centimetres high and 92 centimetres wide, so you can easily walk in and through your equipment. The doors roll down to keep moisture out and their heavy-duty zips will last for years. The extra weather cover protects your gear when not in use. With the large weather cover included, you can protect your gear from the hot sun or a surprise rain shower during the day. Or even from dew at night. The modern, coated and waterproof material keeps all unwanted weather influences away from your equipment. Included are cords and pegs to tie down the tent. The structure also has additional holding straps for the use of heavy-duty straps, which can be purchased at local hardware stores.

The BRESSER First Light AR-102/1000 telescope is ideal for both ambitious beginners and experienced astronomers. Discover the stunning features of Orion Nebula, which is located at a distance of 1500 light years (14,200,000,000,000 km) from earth! The stable mount keeps the telescope stable, even at higher magnifications. Thanks to the high-quality mechanics, you can take your own photos of the moon and marvel at the dividing line between night and day (terminator). The refractor telescope features an equatorial mount (also called a parallactic mount). Thanks to this two-axis mechanism, it is possible to compensate for the rotation of the earth, enabling you to precisely track your desired celestial object. The telescope also comes with a wide range of accessories for exploring the night sky, including a prism for an upright and laterally correct image. FEATURES High-quality achromatic refracting telescope Diameter: 102 mm / Focal length: 1000 mm F/9.8 EQ-3 equatorial mount Height-adjustable tripod with accessory shelf Made primarily of metal Excellent focuser Prism for an upright and laterally correct image Includes wide range of accessoriesDELIVERY CONTENT First Light AR-102/1000 optical tube EQ3 mount Tripod with accessory shelf 2 eyepieces (PL10 & PL25) LED red dot finder 90° upright prism 3x Barlow lens Smartphone holder

With teleextenders it is possible to extend the effective focal length of a telescope system, resulting in higher magnification for the observation of the moon, the planets or small Deep-Sky objects with the same eyepieces. So you can use the advantages of eyepieces with longer focal length - such as the bigger eye distance and the more relaxed observing comfort - at high magnifications also.These teleextenders incorporate a telecentric optical design that deliveres a excellent image sharpness over the whole field of view and are premium choices for visual observations and astrophotography. The combination of excellent fully multicoating with superior optical design makes the Focal Extenders superior to classic Barlow lenses.Features: Suitable for visual observations and astrophotographyDoubling the effective total focal length of the telescopeFour lens telecentric design Fully multicoatedFilter thread for color or nebula filters

NEW - now including a high-quality aperture Solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation.The BRESSER Messier 8'' dobsonian is simply a breakthrough. Despite of its low price this telesccope offers a versatility and quality rivaling a lot more expensive telecopes. The optical diameter of 203mm (8'') does not restrict your observations on solar system objects like the moon or the planets - you can reach farther into the sky and explore globular and open clusters, nebulae and galaxies. With that telescope those objects are beginning to show structures: globular clusters are no longer only fuzzy blobs, but are resolved into masses of individual stars. Nebulae, that can only be barely detected in smaller scopes, reveal structures within. The telescope is setting a new standard in versatility: the excellent Hexafoc focuser boosts a free diameter of 65mm (2,5'') so that you do not have vignetting in big widefield eyepieces that is caused by smaller focuser barrels. The big altitude wheels handle those big, heavy eyepieces without problems - and when you intend to load even more (like a binocular viewer with two eyepieces) then you can move the tube in its tube rings and achieve balance within seconds. The excellent rigidity of the focuser makes focusing a snap - even for astrophotography. This is another virtue of this highly versatile telescope system: you can remove the altitude wheels from the tube rings, attach a dovetail and use the optical tube on a equatorial mount for astrophotography - in minutes. The focuser is handling even heavy cameras tilt and shifting-free. You are extremely demanding in your image sharpness? No problem - with the optional 10:1 gear reduction sharp images are easy. If you consider, that the focuser is that part of the telescope that is used most often, you will recognize the quantum leap this Hexafoc represents in a telescope of this price range. With the included standard accessories (6x30 finder and 25mm SPL-eyepiece) the telescope is ready for observing. If you need to transport or store the telescope as compact as possible you will like this: the rocker box of the 8'' BRESSER Messier assembles and disassembles extremely easy and fast due to the use of metal standard furniture fasteners. So you can transform the bulky rocker box into a handy flat package of boards. This telescope is setting a new standard in usability, versatility and performance in its price class.Please note: Reflector telescopes with optical design Newton are very good for astronomical observing at the starry night sky. But these telescopes are not well usable for observing landscape and nature during daylight. Therefore we suggest BRESSER refractor (lens) telescopes for landscape and nature observing.

With the introduction of the 68° Series we are pleased to make two important improvements in eyepiece manufacture, the first being 15 layer Enhanced Multi-layer Deposition (EMD™) coatings on all glass-to-air surfaces to gain maximum contrast, and waterproofing the eyepiece with the use of Argon gas purging instead of standard Nitrogen gas. Although Nitrogen is a fine choice that will last for many years, Argon is a larger molecule that maintains its protective properties over a wider range of temperatures, and is even more resistant to diffusion thereby further extending the protective waterproof environment of the eyepiece body. Through computer-optimized design, a careful selection of optical glasses, and enhanced multi-layer deposition coatings, the Explore Scientific 68° Series™ eyepieces produce long eye-relief and ensure high image-correction, a flat field, and high contrast across the entire image field. An excellent choice for those who make extended visual studies of detail with subtle variations of brightness, and for those who must wear glasses while observing. All 68° Series eyepieces are fully EMD (Enhanced Multi-Layer Deposition) coated and edge-blackened to produce superior contrast.
