Re: My Zeiss Microscopes

Ideal solution for an infinity system.

Made to order phototube I suppose, is it adjustable?

What is the camera sensor size?

Re: Diatoms from the Seychelles!

Diatoms are a bit like architecture - once you have grasped the general concept it becomes understandable.
It would be nice to have 3D representations of some of them.

Re: Diatoms from the Seychelles!

Here comes the next diatom, probably girdle band view and of a very interesting shape. Do you have an ID for this one, Glen? http://www.microbehunter.com/microscopy-forum/download/file.php?id=16266 Bob I think it might be a Biddulphia possibly Biddulphia capusina or Biddulphia tridens: https://www....

Re: Diatoms from the Seychelles!

Thanks for the link - useful to have. I have to agree that it is not Licmophora (I am still in shock) but neither is it Cocconeis Note that the plate numbers are above the image, not below. That would make it plate 6 See link below for confirmation So looks like it is: Climacosphenia elongata https:...

Re: Diatoms from the Seychelles!

Very nice image, like how it shows off the variety and detail. Great ad for diatoms. Long diatom running left to right looks like the valve view of a Licmophora https://naturalhistory2.si.edu/smsfp/IRLSpec/images/Licmop_grandi_1LG.jpg http://www.microbehunter.com/microscopy-forum/viewtopic.php?t=783...

Even though the COL would be better with a larger annulus I think it still shows it to be a good step up on brightfield.

Stauroneis phoenicenteron (COL-DIC)

-
Planapo 63x/1.4, COL and DIC, 100µm length stacked in Photoshop

This is from a Klaus Kemp 8 Form slide

Not the fairest of comparisons as I used the position III phase annulus in the condenser to achieve COL and it is a little small for best results with the 63x

New members can receive a PM but can not send them until either a certain time has passed or they have posted x number of times. Not sure which or how much/many

Once you can send PMs you will notice that the they stay in the outbox until the recipient has seen them, they then appear as sent.

Re: Help attaching full frame DSLR to Olympus BX40

I guess the only thing I can say in favor of that is that their competition is new adapters bought from the original manufacturer, which are probably similarly priced. Indeed, in fact they are probably a bit more. Still, paying institutional prices does not even make sense for an institution, let a...

Re: Help attaching full frame DSLR to Olympus BX40

But spot imaging (or diagnostic instruments) will have done reasonable testing and something you get from them should yield at least acceptable results. But it does come at quite a price. Given those prices ($650 and up) - acceptable does not seem to me to be acceptable. It would have to be at leas...

Re: Algae, or Desmid (or is that redundant)?

- Perfect matches are difficult with photos - that's why drawings are still so useful Wiki has quite a list, so there is a lot of variation and most probably several which have not been described properly.

Re: Algae, or Desmid (or is that redundant)?

Ok Coelastrum sp. looks to be correct. So not a desmid.

Hope you don't mind me fiddling with your image. Will remove if you wish.
