Some living diatoms I

Not too much activity in my sample that I took from a dewatering channel, but diatoms are always nice to observe.... https://up.picr.de/37969452vs.jpg https://up.picr.de/37969453jr.jpg https://up.picr.de/37969454rt.jpg https://up.picr.de/37969455sm.jpg https://up.picr.de/37969456dv.jpg https://up.pi...

Re: 23.2 vs 30mm

Speaking of FOV I replaced my Leitz 1x objective turret with the 0.8x, combined with the Fluotar objectives and the 30MM 10x/26 eyepieces, the FOV is incredible. There is a point where it is probably overkill as I find my eyes wandering around-LOL. Some may find this interesting in context of the F...

Re: Olympus BX60F

Hi Zero,
the adaption of a DSLR to your BX60F can be done rather cheap: just a tube without any optics:
viewtopic.php?f=24&t=5930&start=60#p73297.
The intermediate image of the microscope fits the size of DSLR with APS-C sensor size.

And does it need to be adjusted each time the turret is changed?
BX: If you change the objective you need to turn the condensor wheel on step further for the correct match of the DIC prism in the condensor. Since the condensor wheel-turret turns easily and smootly, I have not an issue with that.

Re: Does anybody know this vintage Zeiss?

Hi,
like Bob stated, delamination damage for the PlanApo 100/1,3 is extremely common. Difficult to argue on later price discounts for complete sets that are sold as not tested. And without any light source you cannot even blame the seller, since the microscope was not in working condition.

Hi 75RR, you are right, the tube is not commerically availble, but there is a guy in the Austrian micro forum who fabricates such tubes. Anyway it is not rocket-science, one side connects to the tube head an the other side has the thread for the T2 adapter for Canon bajonet. The phototube itself is ...

Re: My Zeiss Microscopes

Hi Hobbyst46, definitely the Zeiss Standard still performes very well, respectively if equipped with Planapos - and yes it will cost only a fraction of the invinite systems. From my experience I do not think that the SKPL 10x/20 makes a much better performance compared to a KPL 10x/20. So it is a ni...

Thanks for the info 75RR.
I often use water instead of oil for the condensor front lense, just because of ease of cleaning. Works quite well till something like n.A. 1.2 or bit more.

Re: euglenozoa

Very nice catches 75RR. How did you manage the oil immersion? There seems to be quite a thick liquid layer under the coverglas and this usually causes issues for such high n.a. objectives (low working distance) and oil immersion (movement or "pumping" of the coverglas due to re-focusing)? .
