Re: Diatomée

Dear vasselle,
fantastic photo, very nice.
I am very interesting to your diatoms sample.
In which locations were taken?
If you want, i have the possibility to clean samples and prepare for you permanent slides mounted in Zrax or Pleurax and ringed as in the victorian period.

Re: Another Diatoms

Also as you know much better than me, is very important to use the oil between objective and slide and especially between the slide and the condenser. I must say that the condenser of the Lomo: Aplanatic N.A. 1.4 and oblique illumination is one of the best ever. With this type of condenser can not o...

Re: Another Diatoms

To improve the resolution it is important to use the light in the frequency of ultraviolet (360-400 nm). Then capture images with a monochrome CCD equipped with an ultraviolet filter as the Wratten 47, or even more selective filter but still are very expensive. During the image elaboration there are...

Re: Another Diatoms

Thank's for your compliments. I have two camera ASI120MM (monocrome camera) and ASI 120MC (Color camera). I prefer to use the monochrome CCD because inside there is not bayer filter, and i have the possibility of using selective filters in a particular area of the optical spectrum. For the spots in ...

This is a tipical procedure used in astronomy to have the greatest number of possible details from an image with minor noise and also works perfectly in microscopy. When you have saved an AVI format file in the personal computer, you can process the file to obtain a single image with a good signal-t...

Re: Radiolaria from Java

For illumination i use a spot light self-built with a series of high intensity led powered at 12 v.

For stacking a series of photo i use a very good freeware software called "Picolay".

Re: Amphipleura pellucida and Frustulia romboides

I use a Leitz Plan Apo 100x 1,32
and Lomo Aplanatic 1.4 condenser for direct and oblique illumination.
Use oil between Objective and slide and between slides and condenser.
