Thank you Marek & David
After recent correspondence in this forum regarding flash microphotography, I started thinking about replacing the 20W led by an electronic flash.
This is a Canon Speedlite 580EX (which I already had) that works fine with EOS DSLR's. I just positioned the flash in the upper opening and gave it a go.
Conclusion is that the flash is excellent for making pictures through the Ultropak, noted a more detailed, less blurred image with more contrast.
The light output of the flash had to be decreased one or two stops; the flash -with a guide number of 58m- generates more than enough light for any magnification. As a secondary lightsource I've been using an Jansjo for observing in live view.
To be honest this is goodbye to Led, as far as it concerns Ultropak anyhow.
About the object: Another silverfish, much smaller than the previous one was captured and killed.
In the first new image no.18 it seems to be smiling; probably because it knew that its colleague already got a lot of views on this forum!
In this picture the distinct mouth parts are combined with the scales and hairs you already saw in previous images. It appears the mouthparts are relatively much bigger (compared with image 3). Would this be related to the age of the animal??
19: 6,5x (Ultropak) top view aft part. A bit of the "rainbow effect" can be seen in these back scales as well.
20: 42x (Ultropak) ditto, detail of scales. Clearly more detail and definition than a similar photograph made with previous setup (unpublished)
21: 4x (Ultropak) top view forward part.
18 and 20 are now on my website @ 1536 pixels.
