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.

Product description Classy CNC Tube Rings with elegant design and uncompromising quality A beautiful telescope should be attached to the mount with perfect tube rings, too. Here, a beautiful look is as much in demand as gut technical properties. The CNC tube rings fulfill these requirements. The tube has only 8 mm distance to the bottom side of the rings, thus the mount is not additionally loaded by unnecessarily long levers. The tubes have plane support surfaces on both sides with five female M6 threads on each side. 1 M6 thread in the middle, 2 M6 threads at a distance of 19 mm from the middle, 2 M6 threads at a distance of 30mm from the middle. With this, you can easily attach dovetail bars and accessories. With only 5 mm thickness, the rings are lightweight yet very stable A thin layer of felt was put on the inside of the tube rings for avoiding scratches. However, the tube is clamped very well in the rings and does not change position. That is important if a guiding scope is attached to the rings. Delivery contents Set of 2x Aluminium CNC Tube Rings

TS Adapter for recessed adaptation of correctors in the focuser UNCN3M82 The TS V-Power focuser with the M82 threaded connection on the camera side accepts large correctors up to 3" body diameter. This adapter allows correctors to be connected via the M68x1 male thread on the corrector. The corrector is recessed into the draw tube, saving valuable optical path. Tilting, as is possible with clamping, is eliminated by the screw connection. On the camera side, the adapter has an M48x0.75 male thread for further adaptations. How the adapter works and what to consider: ♦ Screw the corrector into the M68x1 female thread of the adapter. ♦ Then screw the adapter with the corrector into the M82x1 female thread of the focuser. ♦ Please consider that the adapter needs 9 mm travel (length of the M68x1 female thread and overall length of the adapter) - these 9 mm must be subtracted from the working distance of the corrector. The advantage is that all larger correctors offer a longer working distance. Application example: TSKORW3 on a 325 mm f/4 Newtonian with this adapter: ♦ working distance of the KORW3 Wynne corrector is 64 mm ♦ 9 mm optical path to be subtracted - so 55 mm remain from the M48x0.75 male thread on the adapter. Ideal therefore for all photo adaptations ♦ The exact working distance can be established with suitable adaptations and tuning rings.

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.
