EXPLORE SCIENTIFIC 3" 0.7x Reducer/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. SPECIFICATIONS Reduces the focal length by 0.7x at f/8 Flattens the field for astrophotography Developed for ED127 und ED152 APO telescopes Also fits Explore Scientific ED102 and ED165 telescopes - and others Free aperture: 65mm Inner thread for telescope adaption: M76x0.75mm Outer thread for camera adaption: M72x0.75mm 3" focuser barrel adaptor included Adaptor for Explore Scientific focuser M54x0.75mm included T2 camera adaptor M42x0.75mm included Diameter: 78.5mm; length: 100mm Length without adaptors: 52mm Weight without adaptors: 530g What's Included Reducer/Flattener 3" focuser barrel adaptor Adaptor for Focuser M54x0.75mm T2 camera adaptor M42x0.75mm Dust caps

EXPLORE SCIENTIFIC HR Coma Corrector
After three years of testing and refining we are extremely proud to present the new Explore Scientific High Resolution (HR) Coma Corrector. This corrector is a class of it´s own - it is fully functional for visual use and expands the focal length by only 6%! The Explore Scientific Coma Correktor is delivered as a complete set together with a rotating helical focuser with laser-etched scale, so you get a full package: corrector, adaptor to T2 (M42x0.75mm), adaptor to M48 (M48x0.75) and the helical focuser for visual fun. This coma corrector really is "high resolution" - it deliveres a visual polystrehl performance of 0,98 at f/4 and 0,96 at f/3! So it can stay in the telescope - and you will not only enjoy a tack-sharp Jupiter, but aslo sharp and defined moons in the future! What this means in terms of performance is shown in the three pictures with the graphs - the sharpness increase in those comparisons with and without corrector are stunning (examples are 400mm f/4, f/3,5 and f/3). Please notice: These graphs are for FLAT FIELD! You will get this performance without refocussing! Diameter of the field is 30mm - it doesn´t make sense to increase this with 2" and fast optical systems. Length of the 2" corrector barrel is approx. 85mm and it can be used with almost all 2" focusers on the market. To use the HR Coma Corrector visually, you need to have at least 32mm spare inward travel at your focuser, while the focus is on the same plane as the focusers end. Photographically there is no problem - the HR Coma Corrector shifts the focus outward by about 35mm, so that you will have no problem in achieving focus, when you are able to focus your camera without the HR Coma Corrector.

EXPLORE SCIENTIFIC MPCC Field Flatt.ED APO+NikonT2
The image plane of many telescopes is not plane, but curved. This results in a picture that has its optimal focus only in the center of the field of view - the edge of the field is out of focus and thus unsharp. The human eye is able to accomodate most of this but a camera will show stars that get increasingly unsharp towards the edge of the field. The Explore Scientific Multi Purpose Curvature Corrector eliminates field curvature in a variety of telescopes - Explore Scientific Apos and many other refractors and cassegrain telescopes. This increases the edge sharpness in the image drastically. Improves edge sharpness not only with Explore Scientific Apos, but also with many other refractor and cassegrain telescopes. This image field leveller fits all Nikon DSLR cameras, but can also be used for other camera types due to the universal T2 thread connection. This requires an optional camera-specific T2 ring. SPECIFICATIONSImage flattener for Nikon DSLR cameras Eliminates the field curvature of ED APO telescopes Can also be used for various cassegrains The image sharpness at the edge is drastically increased 2 inch/50.8mm push-in connector with filter thread T2 threaded connection (M42x0,75mm) Full multi-coating on all lens surfacesStainless steel housing Adapter for Nikon F bayonet included DELIVERY SCOPE Bildfeldebner Nikon (1 piece)
