You can buy XY, Z and XYZ stages on ebay, relatively inexpensively (70 IIRC for XY and Z and something more for XYZ). I haven't used one, but it would theoretically work - they typically have 10mm of movement.

They also make R stages. And you can bolt them together to make, for example, a Z-R.

This are JUST examples - http://www.ebay.com/itm/172049450980 and http://www.ebay.com/itm/321980911484

YOu bought it!! Ok Here is an old photo of mine. The micro scope has an advantage of close to 3 cm of verticle movement this is a lot more than some of the dedicated Z stages.



Focus-Stacking

I purchased a xy stage like this one( it was more expensive than this listing ) I recommend you shop around before buying one. This one will work but with hunting you will find better!

http://www.ebay.co.uk/itm/Microscop...AOSwa39Us5Dn

and I had to modify the xy stage slightly to fit it. I cut a piece of polypropylene to size and epoxied it to the arms that are supposed to hold the specimen slide. This was the trickiest thing to do I had to use card board to support the polypropylene so that it sat level while the epoxy hardened. I then covered it with Camera flock:

I do recommend this product its cheap and very useful to have around and at the price you get more than you need.

There are specific Rotary and XY translation stages available for that microscope you purchased. With hunting you will find one cheaply : Here is an example but please note with hunting ( it will take time) you can find it cheaper and there is a rotating version( Highly recommended).

BTW it took me 6 months to find my microscope at that price so even though you didn't get one with an XY stage you got it cheap... I have seen them bid up to US$100.00. Many macro/micro photographers prefer them to the commercial XY stages as they have much more movement. One person motorised the focusing nob so that it could be controlled by a computer while focus stacking:

I believe its buried in this thread on another forum( this thread was the one that convinced me to buy my microscope stage. I had planned to just add the focusing block to the camera mount arm on my Macro rig( as shown in the various set ups in the following link) but when I got it I realized the microscope stand was a nice heavy sold base and I left it mostly as is:

This is what I use:

http://www.ebay.com/itm/3-axis-XYZ-...AOSwDk5T3c7Q

I have a Rotation stage but I don't find it very useful. Much easier to rotate the camera.

Wow nice piece of kit but at US$250.00 I think a US$35.00 Microscope stand with an added XY stage for US$20.00 ( plus postage) is a very economical alternative. I hadn't really taken notice how expensive those purpose built stages are... explains why the Photomacrography forum thread on microscope focus blocks is so popular

ok did another one it was made up of 9 images. moved the coin by pushing made sure the focus block over lapped. the coin was on a slight angle. I had to re adjust focus on the canon. I think I understand how the staging block would really help this. the final images is very big. I know now that this is going to help with the nickel dollars. I was going to tear my mount apart. change the way I shoot coins wont have to now.

Both nice, especially for a manual effort. I like how the damage to the rim is in focus along with the coin details.

As for size, IMNSHO, s'be'it. You can always downsize the images for publication, web use, etc. but you can't upsize them. Storage is cheap, you can buy a 2TB NAS box for well under $150. That's a lot of 20MB raw images.

ok got my first focus stack done. using the B&L stage. need to find a way to get a ruler on this no problem. if you decide to by one of these x z stages make sure it has the ruler attached. here is a photo of the focus block. here is a 1969 nickel dollar. need to figure out a way. to get rid of the reflection of the lens on the coin

I have an idea how to fix this reflection. I wonder what a ring light would do. I have to wait for one more piece. to build austrokiwi light board. maybe that's the answer. have a great one

I saw a nice setup with a fluorescent ring around the lens but wouldn't a flexible LED strip work as well, be easier to setup and allow for greater flexibility?
