Read moreThis telescope with its well corrected chromatic aberration is ideal for high-contrast planetary observing. With a 100mm aperture and 900mm focal length, this doublet ED telescope has high performance optics and collects about 200 times more light than the naked eye with an exit pupil of 7mm. The use of FPL-53 ED glass means that there is almost no colour aberration and an aperture ratio of f9 means this is reduced even further.
ED glass (extra low dispersion) has very low colour dispersion and a low refractive index. Excellent correction of chromatic aberration is achieved by the combination of this special glass with other optical glass. Improved contrast is achieved by the use of crown glass from the German firm of Schott. The metallic high transmission coating applied to the lenses ensures high light transmission. Star clusters are especially aesthetically pleasing, with images very nearly achieving the 'pin sharp stars' often described when observing through refractors. Sharp images across the entire image can be achieved in conjunction with an optional field flattener. The tube is equipped with a robust 2 inch Crayford focuser with a 1:11 reduction ratio for fine focusing - especially important for astrophotography. The refractor can also be turned into a powerful spotting scope for nature observing by the connection of suitable accessories. Also, the telescope is visually a little gem - boasting an elegant design of the highest calibre, with the tube and finder scope gleaming in an aesthetically pleasing tone of black and the white dew shield and the tube rings acting as stylish contrasting elements within the overall design.
The advantages in a nutshell:
- ED optics provide colour aberration-free images
- high-quality glass from Schott, the German market leader in glass production
- metallic high transmission coating
