TMS-F f mount adapter came in. It fits and works in FX mode, though it isn't parfocal. The f mount adapter's black pipe sticks up a bit from the top of the V-T photo tube. Probably if I saw the end off with a horizontal bandsaw it'll be closer to parfocal. I'll probably try that next. . . . You nee...

.... It's a TMS-F with the adapter on top! I contacted the seller and asked if they would be willing to list it separately. They were, so I bought it! https://www.ebay.com/itm/Nikon-TMS-F-F-mount-adapter-tube/183407968118 We'll see how that goes. If the weirdness with the Y-IDP attachment puts the ...

. . . Personally I have never touched one, but judging from this thread it is pretty much like an FS60 without coaxial illumination. The scope body does not contain much more than a tube lens and beam splitter, so it should not be significantly different. The FS70 usually has slots for inserting ad...

That isn't a shaft encoder. It's two end of travel limit switches to keep whatever the motor was moving from driving into hard mechanical stops and possibly jamming. If you look closely you'll see that there are two independently adjustable half-discs. I suppose they could be used to determine direc...

The first piece looks like it has dovetails on both the x and y axes. Probably for some sort of distortion correction. I'd hang on to this but probably forget about it before I found a use for it. The threaded end looks like it might fit a C mount video camera as you've said. If you have a C mount c...

In regard to sagging you could try, as a first step before taking anything apart; setting the zoom to some intermediate position, 2.5x for example, making a target that exactly fills the field of view, and then coming back a day or so later and comparing the fov to the target. If there's been some s...

How to detect it without taking many photos? I need a simple but effective advice. With your setup as described and without st...

. . . How practical is it to remove the F Mount and replace it with another type please? BR John, you can see the screw pattern in the second photo from the end in Smokdaddy's last post. The three screws are evenly spaced on the circumference of a 52mm diameter circle. There's not room in the metal...

Then you need three pieces. In Smokedaddy's lastest picture the piece at the top between the two chromed rings is called "Adapter A". That's piece #1. It incorporates the F mount. The UFX or AFX body is piece #2. The chrome tube just below the UFX body (you can only see a short segment of it here) i...

You still need an adapter tube between it and the trinocular port .... Oh, I didn't realise that. What's supposed to go between the shutter unit and the trinoc tube? See the 2nd post, 1st picture for an overview. The tube below the black Diagnostic Instruments tube is the adapter I'm talking about....

Thanks Gene That looked attractive at $20 until I saw the shipping is $67 even to the US, and I'm in the UK. There seem to be a lot of similar-looking Nikon contraptions about; I assume that's the only one with the relevant features and fittings? You must be seeing UK shipping. It's $28 to me in th...

Here's a cheaper alternative if you're using a Nikon camera (see the 2nd Photo): https://www.ebay.com/itm/Nikon-UFX-DX-Laboratory-Microscope-Attachment-FX-35DX-Camera-Housing-Unit/152889301379?hash=item2398e99983:g:3fAAAOSwVVRacowe The UFX-II body + adapter "A" together are the same length as the DI...

If it's off a PC motherboard it may be a crystal oscillator. Just a wild guess. The weld around the perimeter was possibly done with a laser welder or a TIG welder in a vacuum or inert atmosphere. I say that because there's no heat discoloration. The ID markings were probably done with a laser welde...
