EXPLORE SCIENTIFIC Hexafoc 2.5 adaptor for 3" 0.7x Corrector

The EXPLORE SCIENTIFIC 3" 0.7x Reducer/corrector, reduces a compatible telescope's focal length by a factor of 0.7x (for around f/8) and 0.8x (for around f/10) respectively. The reducer/corrector not only reduces the focal length but also flattens the field. Although originally developed for the Explore Scientific ED-APOs 127mm and 152mm, the reducer can be used with many systems - for example with the Explore Scientific ED-APOs 102mm and 165mm (please note, this will not work on the Explore Scientific 80mm ED Apo refractors though). With certain telescope focal lengths, a slight restriction of the correction at the edge of the image field can be expected when using full-frame sensors. This unit comes with 3" barrel adaptor for direct focuser thread M54x0.75 (the standard focuser thread of the Explore Scientific Essential series of ED Apos) and T2 camera adaptor. This reducer/corrector features a free aperture of 65mm, so that it can be used even with cameras that have a large sensor - if the telescope allows for this. Note: As previously mentioned, this Reducer/corrector comes with a screw on ring, which fits the standard focuser thread of the Explore Scientific Essential series of ED Apos. For telescopes which are equipped with the 2.5" HEX Focuser, the optional screw-on adapter part no: 0510366 is needed. Other telescopes, not in the Explore Scientific range, with standard 2" push-fit focusers will need the Explore Scientific 2" Adaptor for 3" Corrector - part no: 0510364 to get this reducer correctly fitted.

Are you having trouble focusing your eyepiece or camera? Then use this BRESSER 25 mm extension sleeve to increase the distance between the 2.5 inch HEXAFOC eyepiece extension and the eyepiece or camera. The extension sleeve has an M68x0.75 mm internal and external thread and can therefore be screwed directly onto the HEXAFOC draw tube.SPECIFICATIONSIncreases the distance to the eyepiece/camera Suitable for 2.5 inch HEXAFOC Optical length: 25 mm Internal and external thread: M68x0,75 mmInside black matt coated Material: aluminium, black anodized SCOPE OF DELIVERYExtension sleeve 25 mm (1 piece)

Connects accessories with the M68x1 male thread to the imaging side of the 0.7x Reducer/Corrector 0510360.

This adapter replaces the M42x0.75 Adapter for CCD Camera that comes standard with the EXPLORE SCIENTIFIC 3-inch Field Flattener/0.7x Focal Reducer. Allows the connection of a camera via M48x0.75 thread. The larger free inner diameter than T2/M42 effectively prevents vignetting when using a full format camera. The illumination of the camera sensor is therefore optimised.FEATURESAllows the connection of a camera via M48x0.75 threadLarger free inner diameter than T2/M42No vignetting by using cameras with full frame sensor Fits to EXPLORE SCIENTIFIC 3" Flattener 0.7 x ReducerMade of black anodized aluminumSCOPE OF DELIVERYAdapter with M48x0,75 thread

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 beyond the solar systems enormously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artificial light. The EXPLORE SCIENTIFIC UHC filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colours, their emission lines. Those emission lines are linked to chemical elements - in this case hydrogen at 486nm and 656nm, plus oxygen at 496nm and 501nm. The Explore Scientific UHC nebula filter blocks all other colours (and thereby nearly all of the artificial light) and only the emission line of the hydrogen and oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburban skies for example the Owl-nebula M97, the Veil-nebula NGC6992 or even the bright Dumbell-nebula M27 are not clearly visible. By using this filter you can see the nebulae and their 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.FEATURESenables the observation of emission nebulaeblocks almost the entire artificial lightonly the two emission lines of hydrogen and oxygen passes the filterWHAT'S INCLUDED1x 1.25" UHC nebula filter

The anti-reflection filter is an accessory for the DSII/SFPT double-stack module for the Lunt Solar Systems LS80MT and LS100MT telescopes. Reflections that may occur there can be effectively reduced with this anti-reflection filter if necessary.At the LS80MT and LS100MT multipurpose telescopes from Lunt Solar Systems, double-stacking is possible in H-alpha mode for solar observation with the internal DSII/SFPT double-stack modules (item number 0551395). The DSII modules reduce the bandwidth to <0.5 Angstroms. The DSII modules are designed to show better the surface details of the Sun, the contrast is significantly increased, and therefore filaments and active areas are better visible.But the DSII modules can also induce reflections, which can show up as a strong brightening around the sun. This so-called ''glow'' is not a problem when observing the solar surface. But it can complicate the observation of prominences, and many observers find it disturbing. The HRG/SFPT anti-reflection filter is designed to solve this problem. The filter effectively reduces the reflections. But please also note that the image will become darker by using this anti-reflective filter.The HRG/SFPT anti-reflection filter is easy to install. It is not necessary to return the telescope to the manufacturer, the filter can be easily installed by the user.This filter cannot be used separately! It can only be used on a Lunt Solar Systems LS80MT or LS100MT telescope together with a DSII/SFPT Double-Stack module.SCOPE OF DELIVERYHRG/SFPT anti-reflection filterInstruction manual
