Heres a picture of two stackes. One is made with edmunds Nikon objective (right) and the other one was shot with a cheap 20 dollar objective (left) . I Also skipped some dust cleaning in photoshop in the picture shot with the Nikon.

At that size it is hard/impossible to properly assess and compare.
Which Nikon 10/0.25 is that? Biggest difference usually will be image circle/coverage. All the cheap/chinese 10X objectives I know have unacceptably small image circle. If your mysterious, cheapo 10X covers well an APS-C sensor, that would be a nice finding.

The links to Eye of the honey bee and Nikon micorscope text require logging in, and then they say "This photo is private."

That cheap 10X looks quite good.
One nice feature of the Edmund Optics Nikon Finite Conjugate 10X is that on APS-C it can be pushed down to about 7X while retaining good corner quality.
See http://www.photomacrography.net/forum/v ... 7815#57815 for discussion.

Haven't tried that one. Yep, looks pretty good. Would be interesting to see a test stacks with a "2D"/flat subject (scales, laser printed paper, etc) at nominal magnification and say 7-8X.
