The 55.7 mm thread diameter

that I measured

belong to a 56 x 0.75 thread.

Hello! I’m new here in CN. A few weeks ago I got my hands in a TS-50 that needs some cleaning and maintenance.

Does anyone here has a copy of it’ s manual?

Welcome.

Congratulations to the TS-50. Is it the f/14 or the seldom f/10?

Thank you Josef! It’s the f/14 model. Do you have a scan of this model’s manual/instructions booklet?

No nothing. And never seen such a manual.

There has been a Takahashi site with old product leaflets:

www.takahashijapan.com/ct-products/bnclog.html

Seems to be dead.

 

Would be great if you post some pictures of your TS-50.

We all love pictures ... :-)

The page listing when some things were introduced still works, but not the booklet page.

Thanks Josef and TXStars, I could retrieve the content through The Internet Archive! Here is a working link - hope it helps someone else:

 

https://web.archive....cts/bnclog.html

 

As you both said, it has only the product catalogs and leaflets. Nevertheless, it's nice to have this material!

As for the pictures, here is one from the first day night I tested it, the way I took it from it's wooden box.

 

I still need to clean the body, clean and reapply grease to the mount, and clean the objective lens. I'd appreciate some advice on how to do that.

 

I'm also thinking about making a new 1.25" ocular adaptor directly attached to the focuser, substituting the original, made for .96" oculars.

As far as cleaning the lens, Land, Sea, and Sky, a Takahashi dealer in Texas sells a glass cleaner devoid of ammonia specifically for lenses.  Very helpful if you call for advice.
 

I haven’t taken my TS-50 apart for greasing it, but for cleaning, I just went over everything with cotton and isopropyl alcohol.  Seems like it did a decent job although it wasn’t very dirty.

 

There should be instructions on how to clean refractor lenses on the internet.  Particularly important not to use pressure to “wipe “ the lens, and of course be sure to use an approved cleaner.

 

Takahashi makes a 1.25” eyepiece adapter that screws in where the .965” eyepiece adapter goes.

Thank you, for the advice, Sirius. I'm in Brazil and it's not ease to get products from the US...

 

I usually clean lenses spaying a solution made of distilled water, isopropyl alcohol and a small amount of neutral detergent. Then I rinse with distilled water and let it dry - the distilled water leaves no drying spots left by tap water).

 

I'm specially interested in knowing details on how to open it's objective lens cell.

 

It's grate to know that they provide such adaptor! I'm understanding that you implied that the threads of the adaptor they currently sell is compatible with the threads and diameter of the focuser tube of this old telescope. Am I right?

You can also use the much cheaper Vixen 1.25" Adapter -- it has the same 36.4mm male thread as the Tak adapter.

 

For small spots on the lens exterior faces, I wrap the end of a Q-Tip cotton swab in a sheet of lens tissue, dip that in alcohol, and gently rub it off.  Once that face is clean, I'll breath on it, then gently rub the whole face with a cotton ball wrapped with a lens tissue.  No pressure!  Just a circular glide.

 

Here's some pix from the cleaning / de-hazing of my Tak TS-65P / 500 Triplet...

At these Taks you have adapter rings. More than one. And the last one ends in 36,4 mm female.

As Bob writes you can also use Vixen eyepiece holders.
