I say bring on the custom colors!

Here is my custom blue Zeiss universal I rebuild.
Did you bake the paint? It's a nice finish.
No, it’s just a rattle can job. There are a few little imperfections, but overall I was happy with the result.

Re: Intriguing objective

This is an image I shot with this lens. It is a stack of about 80 images rendered with helicon focus. It is an etched cavity in an aquamarine beryl crystal with some oblique fiber optic lighting with modified Rheinberg illumination also.

Re: Intriguing objective

When I started my Zeiss build a few years ago, this was one lens that I was in search of. Scarodactyl on here kindly let me know that he had acquired such a lens and we made arrangements so that I now have it. While I haven’t used it extensively as my Zeiss is primarily set up for epi illumination, ...

I am no expert, but Chalcedony is one of the many forms of Quartz:

And ‘fossiliferous’ means there are fossils in it

Re: polishing scratched eyepieces

If the top element is flat (I don’t have any experience with these eyepieces) I would suggest laminating a coverglass over the top element and using norland optical adhesive to bond the lens and glass together. You will of course need to cut a coverglass into a round disc to match the diameter of th...
