Re: Reliable Dealers
Thilo Immel Optics at Göttingen is a realiable dealership. A bit more expensive but they know what they are doing and you are in good hands with Thilo Immel.

Paramecium bursaria
I was walking around in the park the other day and couldn't resist the sight of a floating piece of pond scum. Among the very many different things I found in there Paramecium bursaria was one of the most abundant species. I took a short video that demonstrates the movement and a couple of close up ...

Re: Mustard Seeds (First attempt at focus stacking - feedback appreciated!)
Looks very nice, the only thing I'd change would be the angle of lighting so we can see more surface details. Where is your light source situated?

Really nice comparison. The second one looks stunning.

Welcome.

You have now documented nearly all of the 8 form test slide with you 63x planapo as far as I remember from your previous threads. Are you planing on shoo...

Re: Numerical Aperature 40x
Typical NA for a 40x planapo is 0,95. Keep in mind that for a crystal clear image you want the specimen you're looking at to be as close as possible to the coverslip and you also have to adjust the coverslip correction colar. Otherwise the image will lack contrast and sharpness.

Re: Zeiss DIC parts (Slider holders)
In a nutshell you dip the prism in immersion oil which crawls inside the gap separating the two quartz wedges.

According to the author it is quite a durable hack that last for quite a while.

Many thanks MichaelG, daruosha and 75RR. I was aware of MagicLantern for years but never knew how it would perform and affect the actual usability of the camera(bugs, etc..). It contains certain risks such as bricking your camera. For example trying to boot the camera without the AUTOEXEC.BIN file c...

Once I have the have the video files on my computer I use ffmpeg for transcoding and editing. Here I present one of ...
