*The illumination device offers a continously adjustable illumination of reticle eyepieces like the Baader MicroGuide, but also of older ones. It also fits into a few finder scopes. The connector, the M8x0.75 thread, is common with crosshair eyepiecesl so they often can be fitted with this device. The electrical supply works wireless with two button cells SR41/SG3, so there is no risk to get tangled up.

Baader Glaspath Corrector 1.7x for Mark V ZEISS Baader Binocular

Item condition: new and original packed

Baader Glasspathcorrector for binoviewers The corrector is more than just a simple barlow lens that compensates for part of the optical path of the binoviewer. First of all, the corrector corrects the color fringes created by the prisms of the binoviewer. Contrast and sharpness of the image increase. Calculation of the shortening factor: The corrector is installed directly in front of the binoviewer. If the corrector is moved further away from the binoviewer, the magnification effect and path compensation increase. ♦ GWK 1,25x: The optical path of the binoviewer is shortened by 18 mm. ♦ GWK 1,7x: The optical path of the binoviewer is shortened by 41 mm. ♦ GWK 2,6x: The optical path of the binoviewer is shortened by 84 mm. Adaptation to the telescope: Adaptation to the binoviewer is simple. The corrector is simply clamped between the T2 female thread and the T2 male thread. The adapter is automatically centered. For the connection to 1.25" or 2" we recommend suitable Baader adapters which are linked under the accessory recommendations. Further application possibilities: The correctors are not only suitable for the Baader Maxbright binoviewers. Also for other binoviewers or adapters, prisms ... the correctors can be used. Whenever you cannot reach the point of focus with a new accessory, the Baader Glass Path Corrector can be the saving solution.

The SA Barlow lenses have a 4 lens system and are multi-coated.Weight 625 gram With Barlow lenses you extend the telescope focal length and thus increase the magnification for observing moon, planets or small deep sky objects. This way, you benefit from the advantages of longer focal length eyepieces such as the large interpupillary distance and the more comfortable viewing at higher magnifications. BRESSER SA Barlow Lenses These Barlow lenses offer excellent imaging quality throughout the field of view due to their four-lens design, making them ideal for visual observation and photography.

BRESSER Messier 8" Dobsonian 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 (LED-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.

Caran d´ Ache Caelograph Alpha 45 FP Limited Edition 120 Pen 2013 Product type: Fountain pen Brand: Caran d' Ache Model: Caelograph Alpha 45 FP Nib / Refill: M / 18K white gold Accessories: With original box and guarantee booklet This is the first time that a writing instrument has been linked to the celestial vault, the laws of astronomy and the history of time. The Caelograph limited edition, created by Caran d’Ache at its Geneva Manufacture, stems from the technical excellence and the taste for original inventions cultivated by the in-house artisans. This ingenious instrument was designed for admirers of science and for all those who take the time to stop for a moment to gaze at the stars at a given time and place. Available in three materials and three basic latitudes, Caelograph is equipped with astronomic position functions that are manually adjustable, like historical instruments for measurement and navigation. A silent show of the constellations adorns the body of the fountain pen and roller pen. The light of the stars is symbolised by night blue Chinese lacquer scattered with silver particles and in some versions, set with diamonds. A rare one-of-a-kind variation designed for a seasoned collector has been created in solid pink gold set with 22 diamonds. Its piston ink pump, housed in a golden barrel, is crowned with a diamond. Born of a sense of poetry and rare technical precision, Caelograph revives our ancestral ties with the stars and their role in the development of science and art. Edition Alpha 18 K white gold Platinum-coated trim Per latitude 45°N Comes with: Caran d'Ache Caelograph Alpha Edition 45 N Fountain Pen Caran d'Ache Caelograph 30ml Ink Caelograph Alpha Compass

Celestron 200 mm Newtonian with focal ratio 1:5 A universal telescope with much power and comfort The parabolic primary of this 8" Newtonian mirror minimizes spherical aberration to produce a sharper image near the edge of the field of view. This scope is great for intermediate visual observers and beginning astroimagers looking for a large aperture with lots of light-gathering power. As the telescope is meant for users who already have a suitable mount, there is no mount included! The optics An 8" mirror collects a lot of light, increasing the perception of dim celestial objects. The relatively short focal length and the 2" focuser have a positive effect when viewing large objects, as the latter can be seen completely in the large true field of view. Because of the large focal ratio, "hard" nebula filters can be applied when using eyepieces of long focal lenght, resulting in a clearly enhanced contrast. On the other hand, the parabolic primary mirror allows high magnifications - helpful for moon, planets, planetary nebulae ans smaller galaxies. The low obstruction of only 26% gives more contrast, thus having advantages when observing planets. Of course, the fast optics has also advantages in photography, is it reduces the exposure times. The coma, typical for Newtonians, can be eliminated by a coma corrector, achieving high sharpness even in the corners of the image. General Features 8" (200 mm) f/5 optical design with 2" focuser gives excellent wide field views Parabolic primary mirror minimizes spherical aberration to produce a better image Low obstruction gives high contrast Scope of Delivery Telescope Optical Tube Assembly with rings and dovetail bar 9x50 Finderscope 1.25" Eyepiece 20 mm
