Re: AO Cycloptic Photo Tube Components

Hi, can you get a clear, focused image that is not parafocal?

Re: AO Cycloptic Photo Tube Components

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!

Re: AO Cycloptic Photo Tube Components

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 ...

Re: AO Cycloptic Photo Tube Components

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...

Re: AO Cycloptic Photo Tube Components

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?

Re: AO Cycloptic Photo Tube Components

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...

Re: AO Cycloptic Photo Tube Components

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...

AO Cycloptic Photo Tube Components

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.

my first home-grown crystals

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!

AO Magni-Changer problem

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...

AO eyepieces 145 vs 146?

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.

Re: Inexpensive USB 2.0 camera test with two microscope types

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:
