Building on the success of the original FCD-1 ED triplets from Explore Scientific, we are now pleased to offer their new FCD-100 Apos, offering even better colour correction. Thes FCD-100 designs offer a polystrehl value of 0.979 - a level of correction that is absolutely top of the line and priced at an unbeatable level for such a specification.Apochromats are the ultimate choice in small to medium sized telescopes: the combination of compactness, transportability, very high image contrast and sharpness together with the possibility to make excellent astrophotos 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 Alu Hex represents another major improvement in this field - the overall correction (color and spherical) is setting new standards in this price class. The optical design shows a typical polystrehl value of 0.979, an absolutely first class measurement.This small excellent apochromat is a very versatile telescope: the fast f-ratio makes short exposure times possible for astrophotographic use. 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 and storage. This does not only qualify this telescope as the ideal travel scope, it is also the perfect choice for fast observations and for astrophotography. The excellent 2.5" HEXAFOC focuser with 10:1 reduction is perfect for this - and the large inner diameter of 65mm minimises vignetting when used with cameras with large sensors.SPECIFICATIONSAperture: 80mmFocal Length: 480mmFocal ratio: f/6Design: Apochromat with three lenses, two air spaces and FCD-100 glassOPTICAL SPECIFICATIONSOptical design Apochromatic RefractorMagnification from 15Maximum recommended magnification 160ED glass Objective diameter 80 mmFocal length 480 mmAperture ratio 6Angular resolution 1.73 arc secondsType of coating Enhanced Multilayer Desposition (EMD)GENERAL TECHNICAL DATAMaterial OTA AluminiumFocusing system 2.5" Hexafoc DeLuxe with 10:1Colour whiteExtended warranty after online registration 10 YearsDIMENSIONS & WEIGHTSNet weight OTA (incl. accessories) 2.6 kgTotal length 320 cmTotal width 130 cmTotal height 142 cmTube diameter 90 mmTube length 320 mmEyepiece Barrel Diameter 50.8 mm
