Thanks for that advice. Why are 145 eyepieces better please? It seems 147 are very common.
Best regards,

The 145 eyepiece is 10x. The 147 is 15x. The AO570 body has magnifications from .7x to 4.2x, so the effective magnification with the 10x eyepiece is 7x to 42x. With the 15x the range of magnification is 10.5x to 63x. ?The 42x magnification is plenty and the 7x is a very useful wider field of view.?
The AO catalogs actually call for the AO 184 eyepiece if you want a 15x eyepiece for the AO 569 or AO 570. The AO147 eyepiece was for the American Optical Cycloptic stereo microscope. Since the AO engineers spec’d the 145 and 184 for the AO 570 I suspect there are differences appropriate for those microscopes.
