Thanks again, Phil. I think i'm going to jump off the wagon and return my incomplete photo adapter and wait until i can find a complete one! I'm excited to set one up, but i don't like being a pioneer with so little knowledge!

Thanks again to all who contributed!

Thanks Phil. I looked again through a makeshift tube; the image looks good to me across the field, but it is inverted and lower magnification than through the eyepiece (15X setting on the magnichanger through the eyepieces is similar to 20X on the magnichanger through there photoport, both with 10x ...

Thanks Michael. I'm somewhat confused but it probably all makes sense to someone! I think my confusion relates to the fact that I don't have the second relay lens mounted in the black ring as noted by wporter. The measurements I show below result in a mounted 146 eyepiece being in focus (using my ey...

These came out nice.

Hi all, I found and purchased an original AO photo tube and will post its dimensions when I receive it. Thanks again for the support.

Oops, just heard from dealer, they don't have it... Ugg

thanks guys. providencecoins will make a custom one if i can determine measurements.

Phil suggested holding a camera above the open port and finding focus distance. would that be the same as holding the recommended eyepiece?

Ream it out to receive a 23mm eyepiece and you are away to the races. Other option is to find the short tube that was factory fitted to the #638 photo tube adapter. You don't see them like you do the 150mm tube made for the trinocular heads because they were an absolutely necessary part of the #638...

Thanks Phil. I understand the way forward. I really appreciate the expert advice.

The ID of the photo tube at the C-mount is only ~16mm. My eyepiece can neither fit into it or over it.

Thanks again Phil and wporter for all your support. I started this by wondering if I should purchase an available AO Cycloptic photo adapter on eBay so I could connect a USB camera I plan to buy sometime. I will continue to learn about this topic and maybe in the future I'll pursue. For now its iPho...

Thanks again! The OD of the machined portion of my existing tube (that goes into the camera) is ~20mm so I guess that's a fit. The length of the full diameter tube to the end of the c_mount threads is ~94mm. So, my question is, is there a reasonable chance (guarantee not requested) that a USB type c...

Thanks Guys, a lot for me to absorb! I'll study your posts more carefully. One item i'm trying to find first is the tube. I have this one already but haven't set it up on my AO 110. https://www.ebay.com/itm/PARFOCAL-C-MOUNT-ADAPTER-FOR-Spencer-AO-American-Optical-TRINOCULAR-MICROSCOPE/160912801843?s...

Thanks. I don't know, as I don't yet(?) have one. Maybe someone else will provide an answer.

Hi all: how do I complete installation of this Cycloptic photo adapter for use with a simple USB-type camera? I know I need an extender tube, not sure what else. Is there an off the shelf, inexpensive solution? Thanks in advance.

I'm on a mission to achieve results like this!! Thank you!

beautiful specimen! love the shape and detail!

thanks 75RR! actually, I don's have steady hands. I bought an adapter (Magnifi 2 for iPhone X), it works pretty well).

Hi. Inspired by RobBerdan and others' posts, I grew my first crystals today. They are hydrosulfide salts I use to treat my aquarium water. I used a camera polarizer above the illuminator and a small sheet polarizer below the A.O. eyepieces. Photographed with my iPhone. Fun!

Thank you. That makes sense. I'm planning to return it.

If it's not too involved, please share a few words on how one adjusts a magni-changer objective.

Thanks again for sharing your knowledge!

Hi. I'm baffled. I just tried out a new (to me) AO Cycloptic that I bought because it has the more "desirable" "M" Magni-Changer. All works fine EXCEPT I can't get image alignment on magnification level "7" (assuming 10x eyepiece). The right eye image is consistently higher and slightly left. I swap...

Thank you for the comprehensive response, Apo! And yes, I'm enjoying my new (to me) Ultra WF 15X's:)

Hi. I see that the CAT 145 was sold for the StereoStar 570 and the CAT 146 for the Cyclops. Does anyone know the practical difference and are both perfectly fine for the Cyclops? Either preferable? Thank you.

Thanks a lot, that's what I suspected. Probably better for me to get a more expensive one that will allow the .5x lens to be included, like this one:

Any other suggestions welcome.

Hi all. I'm a newbie. Will this inexpensive camera properly attach to a "PARFOCAL C-MOUNT ADAPTER FOR Spencer, AO, American Optical TRINOCULAR MICROSCOPE"? https://www.ebay.com/itm/PARFOCAL-C-MOUNT-ADAPTER-FOR-Spencer-AO-American-Optical-TRINOCULAR-MICROSCOPE/160912801843?ssPageName=STRK%3AMEBIDX%3A...

I thought so, but wanted to be sure! Thanks again.

Inspiring!! I'm going to try the simple polarizing setup you describe!

Thank you.

Thanks guys. apochronaut, does your technique negate the need for PeteM's step 8?

Thank you, very much PeteM for the thorough and clear response.

My prism was still attached on one side although it could lift on the opposite side. I was almost certain that attaching the loose side would result in perfect positioning. But it didn't. Maybe I'm at step 8.

Thanks again.

Hi all, I picked up a damaged Cycloptic scope when I purchased a nice table boom stand. The stereo image would not form as the images weren't aligned. One prism was partially loose and was probably hanging out of position. More out of curiosity than necessity (it also has a damaged eyepiece), I adde...

I was able to purchase a set of the 15X Ultra WF eyepieces suggested by apochronaut on eBay. I'm super impressed with the image clarity, brightness and field of view. So cool to own optics that are part of our cold war history! Thanks again.
