Another beauty, Rogelio. Lately I don't comment your posts as I'm a bit tired of saying wow...

Nice!, the tentacles are beautifuly rendered.

After seeing your camera and setup I'm pretty sure your main problem is vibration blur: this camera doesn't have EFSC and needs to close and open the shutter to begin the exposure, your expossure time of 1/15 is fully in the territory where shutter vibration is more important and your enlarger long ...

You are asking many questions but for much of them we not have enough info to make an useful answer. Please give information of your equipment (microscope or bellows setup, complete specification of the microscope objective, camera, camera parameters, illumination...), better with pictures. - vibrat...

Is the 75mm Rodagon D2x optimized for 2:1 in a forward or reversed direction? Reversed. Are you sure about that? Then wouldn't it be a 1/2x lens like the 95PN? Makes no sense, since then a user could not buy the lens and use it out of the box on a duplication machine without first finding a 40.5mm ...

Excellent work, both beautiful and horrible (I allways hated tabanid bites, but is nice to understand its ellaborate mechanics)

A big ciliate, any ID help wellcome.
The beast was dying, you can see the deformation in the lower picture part, perhaps due to the coverslip pressure.

Excellent pictures as allways.
The first one may had some trouble to divide while digesting this long diatom, did you follow the process?

thanks, Rogelio, far from your level but improving...

thanks Mitch,
The animal did not move, perhaps trapped between the slide and coverglass.

If I want to mount a sony nex5 to my microscope without a lens, I suppose I need a photo-eyepiece. Be aware that the Martin Microscope adapter and the eBay ones mentioned above do not provide any additional chromatic correction which was often provided by older microscope systems eyepieces. Don't f...

Excellent pictures, beautiful and detailed.
