the time has come to order my tak.
but before ordering, i need your help.
1- I want to do visuals only.
The FC-100DL is a full-fledged long focal length apochromatic refractor from Takahashi. This is the same FC-100DL that was offered in limited quantities in previous years. With the exception of the focal length, it is identical to the FC-100DF.
or may be the ,
The FC-100DZ is a fluorite doublet with a 100 mm aperture and an 800 mm focal length. In this doublet design, Takahashi has paired the fluorite element with a low dispersion glass having a high refractive index. This combination provides excellent optical performance across the entire visible spectrum with a Strehl ratio in excess of 97.6% across this range. In addition, to satisfy the increasing demands of today’s imaging system, this glass combination minimizes the blue halo sometimes present at shorter wavelengths. This halo intensity is reduced by about 50% when compared to the existing FC-100D
So if I understand correctly, this is what I need, is that it?
thank you in advance.
ps, I didn't want to put this post in the other tak treads.
so as not to disturb other posts and participants.
