Re: What grease for turret head bearings?
Can I use this white lightning NLGI#2 Just make sure it doesn't drip (separate) . ATE plastilube doesn't drip and it was cheap to buy when I bought it and is nlgi 2, unfortunately too thick for some applications, but for turret head it should be ok. As it is not a very sensitive place for choosing ...

Re: Mystery Carl Zeiss Microscope
I've seen one of these in a local marine biology institute where my friend works, they don't use it anymore but it is there on display... I think model name was SM XX. Look up on the Internet I like the looks of these, they remind me of rabbits. My guess would be it is from the 1960s or a bit later....

Re: Several choices of microscopes; what's your opinion?
I came here with a similar question a while ago, got the advice to get a used one. Bought an old Zeiss with a lot of accessories (objectives, eyepieces) and never looked back, after that I got few more. Some I kept some passed on or sold... (Still have the first one) Maybe someone on the forum has s...

Or does this not really matter much as far as choosing a microscope for a hobbyist? I searched but sadly found nothin...

Hi, I have a BHS with a 1.4 condenser. Using the printed insert designed by Carl H for darkfield patches. I just had a thought, maybe I could get a PH objective and then print a patch of the right size to obtain phase contrast? Anyone did that, should be possible, why not? The 1.4 is soo good, I lik...

Or for microscopy prepare the specimen nicely, remove the dirt, which is not always easy, especially if you want to keep them ...

Re: PZO mst 127 focus repair
5x eyepieces are a bad idea for visual use. They cover the same real field of view as 10x eyepieces, but shrinks it down to a much smaller apparent field of view. Like looking down a roll of toilet paper. A pair of the good and cheap 10x/22 would be a better option. I didn't know that, thanks for t...

Hi, I just got a PZO mst 127 stereo microscope, the whole package is complete. I'll clean, repair and give to a friend, he'll probably use it for occasional electronic repairs.

Re: Is my head broken/misaligned?
Micrometer is helpful in these situations, if you don't have one you can print or draw a quasi micrometer on paper or transparent foil. Not as precise as micrometer but still with the lowest mag objective you'll be able to see if the view is different in 2 tubes... If it is the same then the head is...

Or without a rail if you already have one you can use... Although you can make pictures just with an adapter, bu...

Re: Magnification of the NFK eyepiece in the Olympus BH-2 system
Hi everyone, I hope you're doing well.
It is cheaper to buy a used full frame camera than nfk 1.67. I have a Sony and it serves me well.

Re: What grease to use for relubricate microscope parts?
Ate plastilube is cheap and good, quite tacky, doesn't separate. (car parts store should have it, it is used for disk brakes)
Depending on the application you may need something lighter, Helimax xp was recommended to me as a lighter grease, but I never bought it as I didn't find it in Europe.

Re: Need help with a stuck part on a Zeiss PM3 tube head
If memory serves me right, the the unit needs to be unscrewed out and not pulled out. The set screw keeps it from turning. I put tape around the exposed threads if it needs more force than just the fingers and unscrew the unit. Then soak in a solvent or WD-40 and work the plunger back and forth. Th...

Re: Need help with a stuck part on a Zeiss PM3 tube head
If you unscrew the set screw I think the assembly should come out. If it doesn't then apply ethanol and try again. Just pull it out. Be careful with 100% ethanol as it might damage the paint. I remember removing the assembly on my GFL, but don't have it here so cannot check. But can't think of any o...
