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..

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.

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.

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.

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.

I just came across this thread.. interesting.
I have an EM2s mount which came new with my FS128 back in 1999. This combo was recommended (for visual) by the then main UK Takahashi distributor.
I bought it in 2017 as my dream scope,in mint, little used condition. The scope is a 1999 build, the mount 1998.
The EM2 is a wonderful mount. So are the Vixen GPDX and GP mounts, but I prefer the Tak..it just works and gets out of the way.
The weak link in my original setup was the tripod. It looks nice but is lightweight and not up to carrying the FS128 and EM2s mount. The OTA only weighs 7.5kg but is a big tube.
The tripod is supposed to be Mahogany but I have electric guitars made with mahogany, and the Tak tripod is not proper hardwood in my opinion, it scratches far too easily and doesn't seem as dense or weighty.
Once I put the FS128/EM2s mount on a home built (not by me) proper fixed height hardwood tripod, I had a nice solid setup for visual. I bought an adjustable astro chair to allow for observing higher or lower placed objects.
I love the big clamshell on the Tak tube too, much easier to manipulate than a pair of rings.
The simple RA drive holds an object in the centre of the field for 30-60 minutes with just a simple line of sight alignment, and the D Cell batteries last me 12 months unless we get a lot of very cold weather.
The stated load capacity for the EM2 is 9 kg but as with most Tak specs they are conservative.
Just make sure to get a decent heavy duty tripod - and of course, take the time to properly balance the OTA, according to the weight you are loading onto the mount..a properly balanced OTA can be moved literally with two fingers 👍😊.
Some photos for interest 😉..
Clear skies,
Dave

That might be the most beautiful scope I've ever seen! Wow! And it performs I'm sure!

I was actually looking for a LW tripod for my EM-2. I ended up with the same wooden one that was under the EM-200 Temma 2 I had about 20 years ago. I traded for it during my trip into PA to pickup the EM-2 as it was all I could find at the time. I did buy an adapter recently from Hutech that would allow me to mount it on the AM5 tripod or one with that Gitzo center opening.

I still have my EM -10 see post 20 in this thread. I had sold the old FC -100 but bought it back a year later.....
Still like the EM 10 now it is on a EM 200 tripod with sold legs
I have not used the EM 10 in quite a while, but last time I did I seem to recall that the tracking was working and you can hear it but it did not seem to be responding to the hand controller. Have to test it out wonder if I am doing something wrong

My EM-10 has this problem, but probably for a very different reason. Many years ago, I loaned it to Carinasoft (owned by Mathis Instruments) to see if they could write drivers for Tak mounts for Voyager. They damaged the mount by leaving it running overnight with the RA lock on, which stripped the teeth off the spur gears. They paid to have Texas Nautical repair it. TN replaced the spur gears, but didn't tighten the set screws so it wouldn't track when I got it back. I had to figure out what was wrong and tighten them and set the backlash myself. When i finally got it tracking, I noticed that the hand controller wasn't controlling the mount, but the software connection from the computer worked fine. Upon further inspection, it appears that, while Mathis was testing the mount, they used voltmeter probes that were too big for the sockets on the Temma control board on the mount, so the controller pins weren't making good contact. I probably should have sent thee mount back to TN first thing, but I hadn't found the connection problem until some time later, as I had been using my NJP mount for most of my observing while the EM-10 was away.

I think i will make my own plate for the Newts and use whatever dovetail holder works best for the fracts.
