Sorry for the delay to publish this post. Thanks to all that answered my post in newbie section!. I received the microscope and everything was OK. I did a superficial cleaning and the microscope works OK and seems aligned and responsive, I not note nothing bad or strange.
I don't know the exact model, somebody can confirm the model? I did the basic comprobation of focus and alignment, but somebody can recommends me some Nikon manual for cleaning and correct verification of alignment or adjustment?.
It had came with the 10x ocular and magnifications it's ok, but exists or it's recommendable change it for a WF version or something better ocular? Worth it?
Thanks to all again for your time and now I need to build ring iluminator and for sure a camera adaptor, then I will still bother all of you in this forum. THANKS
PM: Sorry for the cardboard but I like to isolate the microscope in the picture
