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

LUNT LS150PS Dovetail Bar 150mm (GP level)
This dovetail plate with 150mm length is suitable for Lunt Solar Systems LS50THa, LS60THa, LS60MT, and LS80THa telescopes.The width of the dovetail is conform to the GP-level standard. Therefore it could be used at the BRESSER EXOS 1+2 mounts for example, but also at many other mounts. The telescope connecting screws are 1/4-20 inch size and they do not look out of the rail, which makes this rail a perfect match for many astronomical mounts. The distance between the screws is matched for the Lunt Solar Systems telescopes LS50THa, LS60THa, LS60MT, and LS80THa.FEATURESLength: 150mmWidth: 44mmDistance between screws: 35mmScrews thread: 1/4"-20SCOPE OF DELIVERY1 x 150mm dovetail plate2 x 1/4"-20 screws

EXPLORE SCIENTIFIC 1.25" UHC Nebula Filter
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

EXPLORE SCIENTIFIC ED APO 127mm f/7.5 FCD-100 CF HEX
Highly corrected 127mm air-spaced triplet apochromat (with three lenses) and carbon fibre tube and a 2.5" high-precision HEXAFOC focuser. NEW: Now with hybrid viewfinder shoe to accept different viewfinder holders.    Apochromats are the ultimate choice in small to medium sized telescopes: the combination of compactness, transportability, very high image contrast and sharpness together with excellent astrophotographic performance cannot be bested. The advances in glass manufacturing during the last few years have made true apochromats available to more astronomy enthusiasts than ever before. The new Explore Scientific FCD-100 CF Hex represents another major improvement in this field - the overall correction (colour and spherical) is setting new standards in this price class. The optical design shows a polystrehl value of 0.97 indicating a level of correction that is absolutely top of the line.This excellent apochromat is a very versatile telescope: its reasonably fast f-ratio makes for short exposure times when imaging deep sky objects, but it is still of a significant focal length, making higher power planetary and lunar observation comfortable without having to use really high magnification eyepieces. The high contrast and sharpness of the image provide breathtaking views of large objects like the North America nebula or the Andromeda galaxy, as well as tack sharp planetary images. The telescope is lightweight and compact - the dew shield slides down the tube to minimize size for transportation. Revolutionary glass and precision manufacturing come together to deliver a telescope that offers observing and imaging at the highest level. The Carbon Fibre construction allows this telescope to be used on lower capacity mounts, increasing convenience and portability. Although there are smaller instruments available, the combination of aperture and optical excellence at such a low weight and compact tube makes this an excellent travel scope. The well-designed 2.5" HEXAFOC focuser with 10:1 reduction is perfect for both visual and astrophotographic use - the large inner diameter of 65mm prevents vignetting by the focuser when the telescope is used for astrophotography with large sensors (full frame and above).We offer the very popular EXPLORE SCIENTIFIC Triplet ED APO Refractors in 3 different product lines:Essential Line: HOYA FCD-1 Glass lens, AL-Tube, 2.0" Rack & Pinion Focuser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112084(AL), 0112106(AL), 0112132(AL)), 0112155(CF + 3"FT)). Professional Line: HOYA FCD-100 Glass lens, AL/CF-Tube, 2.5" HEXAFOC Focuser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112086(AL), 0112108(AL), 0112109(CF), 0112134(AL), 0112135(CF))High-End Line: OHARA FPL-53 Glass lens, Carbon(CF) Tube, 3.0" Feather-Touch Focuser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112165(CF))SPECIFICATIONSAperture: 127mmFocal Length: 952mmFocal ratio: f/7.5Design: Apochromat with three lenses, two air spaces and FCD-100 glassWeight: 5.2kg, lightweight due to carbon fibre tubeBackfocus: 150mm above 2" adaptorHybrid viewfinder shoe to accept different viewfinder holdersWHAT'S INCLUDED Optical tube with retractable dew-shield2.5" HEX focuser with 1:10 gear reduction  2" Star Diagonal 99% reflectivityTube rings with dovetail plate and handle Extension tubes for focuser (2pcs)Dust caps for front-lens and focuserHybrid viewfinder shoe
