EXPLORE SCIENTIFIC Zero X Field Flattener 2''/M48 for ED80, ED102 and ED127 APO

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

EXPLORE SCIENTIFIC Extension Ring Set M48x0.75 - 5 pieces (30, 20, 15, 10 and 5 mm)

Five extension tubes from 30 to 5mm length with thread connection M48x0,75mm in a set. For adjusting different distances of the camera to the focal plane of the telescope or the corrector/field flattener. There is an M48.0,75 internal and external thread in each individual tube. The M48x0.75 thread is also called large T2 photo thread or 2.0 inch filter thread. Camera specific bayonet adapters or color and nebula filters can be used. Included are 5 different tubes with the steps 30, 20, 15, 10 and 5 mm. The larger free inner diameter of 45.0 mm effectively prevents undesired vignetting of the camera sensor. The outer diameter of the sleeves is exactly 50.65 mm and can therefore be mounted directly in any 2 inch diameter eyepiece adapter.

BRESSER Barlow Lens 2x 31.8mm/1.25"

With the usage of barlow lenses, you can extend the equivalent focal length of telescopes and hence increase the magnification of your observed targets. Subsequently, you can use lower power eyepieces in Barlows to act as much more powerful eyepieces, but retain the larger ocular size and more comfortable viewing that comes with lower power eyepiece designs.Due to their two lens design, these Barlow lenses provide a brilliant image quality for the whole visual field and are suitable for observations and photography. The black coloured Barlow element cell in this BRESSER Barlow Lens 2x 31.8mm/1.25," can be unscrewed and has the same thread as 1.25" filters, allowing it to be mounted in 1.25" eyepieces, t-adapters and other accessories, giving you flexibility of use and the ability to vary magnification in different accessories. For instance, the black Barlow cell screwed into the average length nosepiece of a standard push fit t-adapter will give around 1.6x magnification on an attached DSLR. This can be very useful when trying to get to photographic focus with some Newtonians and Solar Telescopes, which lack the necessary amount of in focus travel to get a camera to a prime focus position.FEATURESsuitable for observations and photographydoubling of the focal lengthtwo lens designfully multi-coatedWHAT'S INCLUDEDBarlow lens (1pc)
