Tried again with sixpence and failed.

No real gain at this magnification could have reversed lens and got better image but wanted to try out system.

Main problem is no aperture control or gain on CCD so with D-SLR and stopped down lens reversed normally will work better than microscope at x4.

However pre-prepared slide on table with vernier control far easier than D-SLR on tripod.

The whole set of close-up lenses will just about get same result.

Nice, you might try ebay for some linear rails (http://cgi.ebay.co.uk/Bosch-Rexroth-linear-bearing-with-90-mm-rail-R044271301_W0QQitemZ170439901424QQcmdZViewItemQQpt ZUK_BOI_Industrial_Automation_Control_ET?hash=item 27af0280f0) and some micrometer heads (http://cgi.ebay.co.uk/Two-M-W-1-2-micrometer-heads-NOS_W0QQitemZ270526264741QQcmdZViewItemQQptZUK_Mea suring_Tools_Levels?hash=item3efc9f35a5)

With these you can make an inexpensive stage the will allow very precise movement. Light spring opposite the micrometer head to maintain the position.

Microscope already has it built in. The PC control of the USB video device is main problem. As a video I have some control but as a still everything is auto controlled by PC.
Also no aperture control.
At x10 and x40 the microscope is far better than D-SLR but at x4 really speaking the two are about even.
The microscope is also very limited to table adjustment can't take images of a watch it's too thick.
These two first with D-SLR with 28mm lens reversed second with light microscope.
Was it really worth all the effort using Photoshop to blend images? If anything one with reversed lens is better!

Sorry I miss-understood I thought you were building a stage to use with your camera.

May as well. I was so proud using 9 images with Photoshop to get the blend with microscope then used lens reversed and got better result with just one image.

Of course live with microscope one is re-focusing all the time and it works well, but the USB unit is OK as moving image but not so good for stills.

Until one tries of course one don't know. The zoom lens that came with D-SLR does not have an aperture ring it's electric coupled to camera so I can't reverse it and adjust aperture so I have to use old lens which at 28mm is not best to reverse.

But with extension bellows (also will not work with new lens) and close up filters I can set up to take most macro and close-up. Bit Heath Robinson though with bits of black insulation tape over part of flash etc. But it works.

Using long lens and bellows have produced some good close-up for insects etc. As I can leave good distance between flower and camera. Deck chair job with cable release reading book while waiting for bee.

Another inexpensive lens you can try is an enlarging lens on bellows. Now people are almost giving them away and they are good for macro.

Web cam picture of slide on keyboard http://www.photography.ca/Forums/members/ericmark/albums/odd-pictures/320-slide.jpg to give some idea of scale. Pre-mounted slide was one of the practice group which came with microscope. The green dot above "Page Up" is the item photographed.

Either Pentax mounts will do I have both screw and bayonet adaptors I would like somewhere between 135mm and 200mm (35mm size) must be able to work manual and that seems a problem with newer lenses.

Other option is doubler. As it is new lens stops around 55mm CCD size and old fixed is approx 270mm CCD size (400mm 35mm sizing) and really too much gap between the two.

It's on my want list.
