a friend machined them for me from SS

Does anyone know how much weight the old EM-90S can hold? I have been using the FC-100DL with it and it's amazing. It's between the EM-10 and the EM-200 in size. 

Never heard of it, post a picture

Me neither.  I find most of my Tak history info here:  http://astrosurf.com.../takahashi.html . and it's not on there.

It is not an EM series mount, it is just the 90s. 

 

Here is a thread with some nice pictures..

very nice!

That mount came with a TS 90 package, the first fluorite Tak in 1977.

It is a rare bird i would kill for. I love all them pre 1988 Tak mounts.

Stilllooking for an em500 temma2 and pier but have only seen one. The price was up there. I think they can be found cheaper. Have watch my retirement dollars.

I bought my EM-500 for $4000 about 10 yeas ago.  Pre-goto, but I added a Sitech servo kit to it for a few years.  That works very well and isn't expensive.  TN quotd me $4000 to add Temma 2 to it.

FS-78 on EM-2S

 

 

 

 

[DaveTinning]

Just came across this thread.

 

This is my EM2S from 1998 carrying my FS128 from 1999. It was sold new as this combination by the then main UK Tak dealer, Tru-Tek.

 

It originally came with the Tak tripod, first pic, but I had a more robust home built wooden fixed height tripod which is more stable with the FS128, so I sold the tripod and have used this one since.

 

I'm visual only, and this setup works great for me. It has just single RA electric drive (4xD Cells, last for ages). It just works.

 

The only downside to this mount is that the adjustment only goes up to 50 degrees, I am 53 degrees north. For visual alignment the natural slight slope of my back garden gets me almost exactly centred on my polar scope with Polaris, so no issue at all! (I have seen one other UK EM2 based mount which has been modified to go to 55deg north).

 

A wonderful mount, think Vixen GPDX mass/load with even better engineering.

 

Clear skies,

Dave

Old thread, but right topic: 

 

l’ve very recently picked up an EM-10 with Temma 2 Jr (on the other site.) I’d love to learn more about these specific mounts than what I’ve been able to find online so far.

 

Can we determine approximate year of manufacture from the model and serial number (3xxx) even if only a range?

Like the EM 10 I still have.  Great mount.

Reviving an old thread; I just received a Takahashi EM1 and baffled by this logo; is the polarity central negative or central positive?

 

 

It comes with a battery pack that runs on 4x D-batteries (6V?).  I am hoping to eventually move to a powerbank but want to seek out some advice before accidentally frying the circuit inside.

Center negative.

 That is correct the center pin is negative. It is common for equipment made in Japan. I have repaired a number of telescope electronics were someone used the wrong polarity include Tak's. The easiest way to power one  with a negative center pin, it get one with  a positive center pin ,and  with the correct voltage ,  and current rating and the plug that fits the socket on the scope.  Next cut the plug off leaving a few inches of wire, then wire the plug back on by reversing the wires between  the two cut ends.  Now the center pin is negative. Test the polarity with the voltmeter just to be sure.
