Hello, just arrived from Japan an absolutely in perfect-conditions VIXEN FLUORITE 80s which I gifted my son (attached photo of him with the VIXEN just assembled a after unpackaging, he's surely much better than I...lol.gif ).

 

Wonderful masterpiece from Japanase venerable Vixen (this sample was manufactured probably in 1988, so 30 years old! But lens are absolute perfection!!

 

I want to thank my friend Mr. Koji Matsumoto of Matsumoto Company for assisting me in getting this rare scope with a super professional and friendly approach.

 

Clear skies!!!

Vixen Fluorite refractors

    

     This, in my opinion, is the best classic scope setup to come out of Japan, optically as well as mechanically: the Vixen FL-102S with FL-55S piggyback, on SP-DX mount.

 

     The OTAs are doublet Steinheil design with the positive Fluorite crystal element at the back, -- a combination of compact, light, fast to cool plus a high Strehl across the whole visual spectrum (unlike air spaced triplet APOs or comparable TAK doublets).The 102 has the 2" drawtube and the 55 the 1.25" ditto.  Many unique innovations like the 102 F6.3 focal reducer, polar scope with illuminator, dual MT4 servo motors on RA/DEC with manual or SkySensor 2K computer control. Many accessories and ways of configuring these scopes.

     Thought I'd share these "parting shots" for my wonderful rig with you, as we plan to move to a smaller house and I will have to clear out some of my equipment before we do that. Such is life.

Thanks for sharing this, Allan! That refractor combo looks to be a great one. I hope you can find room for it in your new abode. The link to your ongoing projects is fantastic. I love those old instruments. What superb craftsmanship from a time when high tech meant an entirely different thing. And many of these were not only very functional, but also works of art in my assessment.

 

All the Best,

Russ

There is one point maybe you can shed light on: I'm under the impression that the extreme quality of the steinhel doublet of the FL series was the combining of a flint Kruz KzF2  and the crown Fluorite CaF2. Not just the flourite, the combination of the two...does this make sense?

Russ,

 

     Thank you for your kind words viz. my ongoing observing projects smile.gif  -- for most of these I'm using my Vixen FL-80S.

 

     The focal length ~ f/9, the light build, the fast cool down and the color correction makes the FL-scopes perfect for both visual and EAA/NVD, both rich field and higher magnification. And the FL-80S matches my current Grab-Go observing style perfectly. My decision to pass on the 102 and the 55 is firm though, -- we'll be moving to a smaller house (and besides: I've only got one set of eyes after all lol.gif) .

 

 

 

Marcus,

 

     Yes, surely it is the combination of the crystal fluorite CaF2 element plus the chosen mating element (short flint: KzF2 for the Vixen FL) that results in the superb color correction of the Vixen doublet FL-scopes. The same choice of elements was chosen by Takahashi in the original FC-series of telescopes btw, but since the Schott KzF2 glass was discontinued due to environmental issues we dont see this specific combo any more in later APO doublets.

Can we get back to posting pictures of our Classic scopes? If you want to discuss the merits of Vixen scopes, start another thread.

I found some old pictures of my RV8. Some photos of my old RV8 that I took not long ago.

'Old pictures' make it sound like I don't own the scope any longer but I do still own it.

'Old RV8' sounds like it's really old, but it isn't that old, made around 1980, and 1980 was just

yesterday it seems.

The coatings look excellent to the naked eye and function excellent, but shine a million candle

power spotlight on the back and yuk! 

Strange how some of my best mirrors look like this when 'in the spotlight' I should research this

phenomenon.

Me (on the left side), a friend and my "Quelle Revue Catadioptric 114/1000". I bought this catadioptric reflector in the mid 80s (the price was about 600 German Marks), these catadioptrics should had been produced or designed by Vixen. But on one photo you can see a serial number of Towa.

Between 2013 and 2014 I cleaned and collimated the telescope and modified it a little by changing the focuser (I took a similar old focuser of a Newton 114/1000) and I fixed a Celestron 6x30 finderscope on the tube.

Nice orange reflector, nevertheless the front plate is uncoated glass...

I like your modifications.  IMO, the Towa EQ-2 is a decent mount -- are those the original wooden legs?  I used a motorized EQ-3 for years, and logged 1000s of hours with a Model 339 re-branded Tasco.  It was a very good 80mm F15 refractor that all these decades later, I wish that I'd kept.

I posted at some point previously, but here is my C102F again.  Had some help from a friend to tune it up a little, and get the objective to a pristine level of CLEAN!  Thank you to him.  He knows who he is.  

 

Still learning, and am blessed to have this great scope, and awesome observing partners.  

 

Overcast with spots of hazy openings last night, but still was able to get a bit of action.  Both Saturn and Mars were difficult due to the conditions, but we still had fleeting moments to enjoy.  I know I am not alone, but Saturn is my favorite...for now.  :)

20181006_Observatory_Path.jpg

 

The path to my observatory cannot be seen on a dark night.  As a solution, I found some "glow pebbles" on Amazon and defined some approach markers that can be seen in pitch darkness.  As I get close, the starlight is enough to see the silhouette of the observatory.  Works like a charm!

Thanks.  Its in Northern California, near Mount Shasta.

 

I forgot to mention that the observatory houses a 12" LX200 f10 SCT.

I remember a couple times in the early 70s, when I was in a place so dark that it was hard to tell whether the gray patch was bare dirt, or a boulder 2 feet tall that I was about to run into.  One place like that was in the Rockies of Colorado, when I was in a mountaineering school.  The other time was in the Grand Canyon, on the South Bass Trail (or maybe the Hermit).  It was so dark, Jupiter cast shadows.

I’ve seen Death Valley like that in the late 1960s and early ‘70s. So dark that on a moonless summer niht the Milky Way casts a shadow!
