Re: Agatized dinosaur bone from 0.7x to 60x
... could that iron oxide have been part of the original blood of the dinosaur? Who knows, but I don't think so. Iron oxides and hydroxides in several mineral species are the most widespread pigments that give sedimentary rocks (and of course fossils) their varied colors. Despite the admirably pres...

Re: fly wing
Yes, it's the 3D rendering for sure. Your new video shows the same issue, maybe a little less prominent. Thanks for the follow-up.

Re: fly wing
Nice images, the normal stacks are beautiful although I find the 3D-model ones misleading: what in the stacks (an in a direct observation of diptera wings) are hairs in the models they look like hills, an impression confirmed seeing the 3D animation.

Re: Connecting a DSLR to a Nikon Optiphot
At the camera end you need an adapter without built in lens from the male thread you have,likely M42x1, to Nikon F bayonet, a very easy to find accessory. For example https://www.ebay.com/itm/145360830054?hash=item21d82e3e66:g:OXIAAOSwGhVjYzbc&amdata=enc%3AAQAIAAAA0D05LF%2FKkFgcR5WJw%2FPNeeFmnvsQ8RU...

Very nice, but it seems like your Zinnia pollen, not like Lily (Lilium sp) ( viewtopic.php?p=215041#p215041 )

Re: Questions regarding Nikon universal DIC condenser.
If the DIC components are also for the Optiphot the 0.65 one seems more adequate.
That said, if the 0.75 was adequate it will be nicer...
Is there a Nikon expert to answer it?

Re: Questions regarding Nikon universal DIC condenser.
Not sure (and I'm not knowledgeable on that Nikon stuff) but I'm almost sure that the NA 0.65 is a CF and the NA 0.75 is a CFN. If so, likely each one will work better when paired with condenser and DIC prisms of the same time/series. Is yours an Optiphot or an Optiphot 2?

Very nice and interesting!
I've most enjoyed the study of microscope objectives towards the end of the video.

Re: Fuji GFX microphotography
Hi, some pointers: I am exploring shooting very magnified samples on the GFX system but I have never used a microscope so I am trying to find information about what I need to collect in order to capture well. I am interested in shooting between x500-x1000, with dark field polarized light microscopy....

Re: A very elementary question about cameras
Of course there are more modern -and expensive- options but if you want good image quality and adequate frame coverage on a tight budget, the 5D MkII option seems to me very adequate (providing that it's in good condition and with a clean sensor) The IQ will be similar or likely higher than the 50D ...

Re: wasp
Excellent work!
The stereo makes the structure much clearer: In the first image the left wing front edge end looks very similar to the siting /ovopositor while in the stereo this similarity disappears.

Re: Laowa Aurogon Super-Micro lens test and comparison (versus Mitutoyo etc.)
Hi Jason, At the beginning of the thread I (erroneously) asked Macro_Cosmos ... Could you test the objective at its intended parfocal distance without the "tube lenses"? I'm curious about its rear focal distance and "original" magnification alone, and of course about its IQ, image circle and possibi...

Re: Diatom: Chaetoceros sp. from Paracus, Peru
Very nice!
Are you sure that the location is Paracus and not Paracas? (I have good memories of the Paracas peninsula, a desert place in the Peru coast now a natural reserve where I traveled when young)
