Tak FS Flourites - Quality ?Posted By Ned Leahy |
I have a quick question if anyone is interested in responding:
A gentleman has recently advertised a used FS102 on Astromart, and claims the following -
"Note that this scope is made with the earlier, higher-quality flourite glass that is no longer made. The lower-quality flourite is marked w/ a blue ring around the dew shield. "
For some reason, I have a hard time believeing that a cosmetic change to the tube is indicative of a lower quality standard. How is this related to the manufacturing of the lens group? I am aware of the differences between the FC and FS - the flip flop of the flourite placement, but this is the first I've heard of lower quality anything -especially when talking about Takahashi.
Can anyone shed some light on this subject, or speak to the validity of this remark?
Thanx!
Ned
