Fantastic Photo.
Very, Very nice

Walter

Hello everyone,
These are photos taken from old victorian slides.
The radiolaria are take from Capitan Parry in 1890's in Barbados
The foraminifera are from a famous site in Ireland called Dog's Bay

Hello everyone

I send you some pictures of slides that i made recently with ascorbic acid, sulfur and salicin.
All slides are mounted in canada balsam
For photo i use a old selenite slides (Blue/Yellow)to increase the effect of the polarization.

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.

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...

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...

Your pictures are spectacular.
I really like the live diatoms

Walter

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 ...

spectacular images, really good

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...

Hello everyone, I show you another set of famous diatoms use for test optic. I have acquire a movie of 600 frames, then with a software called autostakkert2 i have stacking the single frame. Then i have use wavelet filter with Registax which is much more selective than unsharp mask use in Photoshop ...

Beautiful photos, very nice

Walter

Thanks for your kind words.
I joined the forum to learn many things from your great experience and
i hope to be able to contribute with my little experience.

Warmest regards

I have a very modest Leitz objective. In oder:

PL APO 63x 1.40 OIL
PL Fluotar 100x 1.32 OIL
PL APO 40x 0.75
PL Fluotar 25x 0.60
PL Fluotar 10x 0.30

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".

Hello everyone,

These are photos from an old papered victorian slide of radiolaria from Java

Hello everyone In these photos I show you my modest microscopes. The first from the left is a trinocular microscope of muller-optronic. I replaced the objectives with good Leitz and condenser with a lomo aplanatic 1.4 NA with oblique illumination. The second is a stereo zoom trinocular always of mul...

Hello everyone
I have a problem to attach photos.
I have reduced below 1024x768 and the file size are 120kb each but the message are:
"Sorry, the board attachment quota has been reached."

please, can help me

Warmest regards
Walter

The measure are:
frustulia romboides, 30 dot in 10 micron
amphipleura pellucida, 37 striae in 10 micron

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.

Hope to see photos of your equipment in the My Microscope section soon!

Early i prepare some photos of my equipement

hello everyone

I have used a monocrome camera ASI120MM and a Filter Wratten 47, in addition to oblique light for these photos.

Happy New Year everyone. Sorry for my english. I joined the forum now. I am passionate about microscopy and particularly collect diatoms, radiolarians and foraminifera. I have collected a large amount of slides and samples over the years, and i am interested in exchanging them. I have a microscope t...
