How to analyze-particles as beginner?

Dear community,

I am totally new in image analysis and have tried alot with ImageJ or QuPath but unfortunately I can’t find a proper way into it. Here is an image example I would like to quantify:

Has anyone a recommendation which software I should use or how I can quantify those little “dots” also finding out their position?

I tried it with ImageJ, but the image quality is so bad that it does not allow thresholding… E.g. here:

With thresholding it seems impossible to quantify just the “little dots”…

Kind regards,

Can anyone give me just a little hint? I would be glad for every help!
