BRESSER Wide field eyepiece 15x/16 (30mm) with diopter setting

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.

Field flattener without reduction factor for Explore Scientific ED80 , ED102 and ED127 APO Refractors The imaging plane of many telescopes is not flat but curved. This means that only the area in the centre is perfectly focused - the edge becomes blurred. The human eye can usually compensate for this image property, but a camera shows increasing blurriness towards the edge of the image field. The Explore Scientific Zero X field flattener eliminates the field curvature in many telescopes with a focal length of approx. 480 to 952 mm. The Zero X field flattener was calculated and developed for Explore Scientific ED80, ED102 and ED127 apochromats with focal ratios of F=6.0 and F=7.5. The image sharpness at the edge is dramatically increased. The stars appear round and no longer distorted - a clear benefit for the whole image aesthetics. The Zero X image flattener can be used not only with Explore Scientific Apos, but also with many other Apos. This flattener does not change the focal length of the telescope. Correction for up to full-frame camera sensors (24x36mm) The Explore Scientific Zero X image flattener has been developed due to the rapid development of ever larger camera sensors. With it, there is finally a field flattener available that illuminates and corrects the field of view for full-frame camera sensors up to 24x36 mm. How to use the Zero X field flattener with M48 thread connection This field flattener has a 2 inch (50.8 mm) plug-in connection on the telescope side, with which it is inserted into the telescope instead of an eyepiece or star diagonal mirror. On the camera side, there is a standardised M48 x 0.75 mm connection thread. This M48 connection thread offers a larger free inner diameter than the usual T2 (M42) thread and prevents vignetting when using large camera sensors. With an optionally available and camera-specific adapter ring, a DSLR camera can be connected to it. The working distance is already set at 55 mm. Of course, mirrorless cameras or special astro cameras can also be used with the M48 thread connection. For this, the appropriate M48 spacer sleeves or adapters are additionally required to set the right working distance of 55 mm. This must always be done with every corrector or field flattener so that the best possible field flattening is achieved.Filter thread on telescope side availableThe telescope-side 2.0 inch plug-in sleeve has an M48x0.75 filter thread (internal thread). Individual 2.0 inch colour or nebula filters can be inserted here to increase the contrast of the images.FEATURESField flattener for Explore Scientific ED80, ED102 and ED127 APO telescopesRemoves field curvature from telescopesProduces round stars even at the edge of the image fieldImage sharpness at the edge is drastically increasedA clear benefit for the whole image aestheticsCorrection of field curvature for up to full-frame camera sensors (24x36 mm)Image field flattener without reduction factorOn the telescope side with 2 inch (50.8 mm) plug-in connection and M48x0.75mm filter threadCamera side with large M48 threaded connectorWorking distance of 55 mm between field flattener and camera sensorFor telescopes with a focal length of approx. 480 to 952 mmOptimised for telescopes with focal ratios from F=6.0 to F=7.5Can also be used for various other APOsFully multi-coating on all lens surfacesHousing made of lightweight aluminium, black anodisedAluminium dust cap for M48 threadSCOPE OF DELIVERYZero X field flattener (1 piece)Dust caps
