Re: My Evolving Nikon Microphot FX

Underneath the yellow cap is a second camera port for video and medium format. There is a spot underneath the turret towards the back where an EPI/fluorescence illuminator would go. Maybe in a month or so after my wallet recovers. I got into microscopy for doing fine art photography. The world of mi...

Re: My Evolving Nikon Microphot FX

Answering some questions… I live in San Antonio,TX. I am fortunate that there is a microscope repair shop in an adjacent town which is factory authorized for many of the big manufacturers. This makes sense as San Antonio has a huge medical school and medical complex. This repair service has been aro...

My Evolving Nikon Microphot FX

I am finally getting around to sharing images of my setup. I don't have all the money in the world so the used and broken markets is where I tend to shop. I wanted a quality name brand microscope that I could find parts for and was upgradeable so I can add features in the future. I settled on a used...

Re: This is probably a silly question

Please correct me if I’m wrong. I think by ratio you are meaning magnification. If this is the case remember that magnification is a function of both the objective and the eyepiece. It is challenging for me to explain microscope optics because I’m most familiar with camera and telescope optics. Micr...

Re: This is probably a silly question

I will do my best to explain. It is easier to explain telescopes than microscopes because they use optical descriptions that more closely correspond to optical specifications in physics and most optical engineering. In telescopes resolving power is dependent on the diameter of the front element of t...

Check out holographic websites. Making holograms require system movement less than 1/2 wavelength. One of the best solutions I’ve seen is using a gravestone on inner tubes.

For now I have ditched the astronomy camera in favor of a canon 7d coupled to a 0.5x eyepiece. This has made a very substantial improvement. But the objectives I initially purchased to get me up and going are definitely not the best. About their only redeeming value is the spring loading on the 60x ...

I suspect some of this may be due to low megapixels. As funds increase I will be trying more things. Thanks again everyone for the...
