Re: Polarized live Diatom (Pleurosigma sp)

Thanks!! Glad you like it.
Seems like a pleurosigma indeed, forgot to mention it is from a marine water sample

Polarized live Diatom (Pleurosigma sp)

Hi, In the last few weeks I could not expend much time with scope and when I did I did not manage to get results worth sharing. A new stack, adapting to the microscope is proving to be quite challenging. Preparing the samples and working with live moving subjects. It took me several times until I co...

Re: How do you clean Sony camera sensors?

I wet-clean my Sony sensors as little as possible, but when I do it is with good quality sensor swabs and absolutely *minimal* alcohol. I use pure methanol (lab grade stuff bought by the litre for other uses - Eclipse is a ripoff). ...... Thank Beatsy, I thought methanol was more aggressive than et...

Re: Experience with lighting/diffusion using a single strobe?

You could use reflectors and these would act as new light sources with somewhat lower output. Start with one opposite to the light source and one or two to the sides. Play with size, distance and angle to get different light effects. Use your favorite diffusion method, that does not need to change.

Re: amscope 4x aliexpress alternatives?

Thanks! I understand that it's a lot to ask of a budget objective but I'm fine with less than stellar per-pixel sharpness as I plan to tile the photos to get higher resolution. Controlling the printer should not be difficult. I allready have a Raspberry Pi acting as a print server. It's just the ma...

Re: software for adding photos

If it is panoramas you want to make the software I used to use for that was PTgui
You can define reference points on the pictures to help the software

Maybe there are better options these days

Re: Help to choose between two Mitutoyo 20x lens

I had several mitutoyos myself, and some performed better than others. I had 3 mitutoyo 20x and I sold a BD plan that maybe did perform slightly better than the M plan I kept but if it did was not by that much. In my opinion different performance can happen because of different versions of the same ...

How do you clean Sony camera sensors?

Hi, I guess this has been discussed many times but here I am. All my cameras are Sony (NEX-5N, A5100 and found a cheap old stock A7 and went for it for small magnification work). Sony sensors a PITA to clean and products/methods used on Canon/Nikon may not work well When I had the Canon 5D mkII clea...

Re: Help to choose between two Mitutoyo 20x lens

I've had to return every 20x Mitutoyo I've purchased due to haze damage to the inner elements. The last unit I bought was from a lab and they promised it was brand new, never used, just stored for an amount of time. I have never seen a hazy Mitutoyo, and I had a few of them. Maybe that problem you ...

Re: Parallel sensor alignment / digital spirit levels

I just use a 5 axis positioning stand ( X, Y, 360° and 2x goniometers), for something like wafers I think is more than enough ; Z axis is the motorized rail for stacking. For other subjects ( even for butterfly wings) the flatter angle is not always the best one. Taking the pictures is just a fracti...
