Takahashi FC-100DC f/7.4 Doublet Fluorite Apochromat Refractor

The new Takahashi FC-100D is fitted with a premium quality F7.4 Fluorite doublet optic that provides superb contrast, sharpness and colour correction. 

Utilises  the Steinheil design with a fluorite rear element and an eco-glass front element. 

A versatile telescope that provides wonderful views at low and high magnifications but can also be used for astrophotography. When combined with the optional FC-76 Reducer the FC-100D operates at F5.4 and delivers a fully corrected 35mm circle that is perfect for APS sized DSLR's. 

The FC-100D is surprisingly light but. like all Takahashi scopes, is very well engineered.

Fitted with a Takahashi Rack and Pinion Focuser with 1.25" visual adaptor, an optional 2" Visual Adaptor is also available.

I had a Skywatcher Startravel 102. I thought it was a great telescope. I wanted to upgrade. I wanted more aperture. However, when I started to research, it seemed that four inches was a great compromise between aperture and portability. And the more I researched, it seemed to me that those who didn't own a Takahashi coveted one and those who did own one fell in love with it! So I went for one and I love it! The views of the moon and the major planets are stunning! And I can see deep sky objects I simply couldn't see with my Skywatcher, despite not having any more aperture. Takahashi have their own way of doing things; don't expect all your existing accessories to work, some people don't like the focusers. But when you delight in the stunning views, nothing else matters. I love this scope so much I bought another Takahashi; an FS60Q (mostly used in FS60CB mode) as a travel scope. I use the Takahashi star diagonal and a mixture of Tak and Teleview eyepieces. Expensive, yes, but if you're lucky enough to be able to afford one, you have a scope for life that will give you the best views possible for the given aperture.
