Back in the early 1990s when I first saw a Vixen fluorite lensed refractor I started wanting a fluorite lensed refractor. It took almost 30 years to buy one, a Tak FC100DL. The wait was worth it.
Though there are equally excellent apos made now without fluoride lenses, that optical acorn "ingredient" planted in my one-day desire to own, remained. Nourished by retirement (out all night, sleep all day), more money saved, and realising that "its now or never", I acquired my 30 year long dream. Not once disappointed yet. In fact I have it separately itemised it in my will to go to my brother along with my TV Genesis.
While maker & brand supremacism are the joint zeitgeists of refractor enthusiasts, in public anyway, does anyone else choose optics, and especially fluoride, as first priority?
I bought my DL under similar circumstances. Back in the 1990s I dreamed of a florite Genesis SDF that I saw in the Orion catalog and the Sky and Telescope and the Astronomy magazine ads. I did a fair amount of astronomy in the 1990s with an Astroscan and a C-8.
Then due to life circumstances and work schedules, I ended up taking about a 25 year hiatus from astronomy. Then in early 2019 I moved to a house that had a nice deck with a south western view and I realized I could do lunar and planetary observing in town deapite the light pollution and I also realized I could afford a four inch florite refractor.
I began my research and discovered Takahashi. Once I learned about the secind run FC100DL, I had to have one and I haven't been dissapointed. The second run DLs come with a microfocuser, which I use regularly for planetary work in difficult seeing.
The DL is a little long to travel with, so when a good deal came along for a used DF in excellent condition I bought it as well so now I have two four inch florite doublets. The DL stays at home and I take the DF when I travel to a dark site. It's short enough to take in carry on, so at some point I plan to fly south with it to get another look at the southern skies.
The DL has given some magical views of Mars from my driveway the past couple nights. Very happy with my pair of florite doubles for their wonderful sharp views, their light weight, their fast cool down, their portability and their overall look and feel.
