Re: 2M4P - Two microscopes Four photos
QCC, I guess an apple-to-apple comparison is never going to be fun as it requires scientific rigors and limiting variables down to minimal. I understand that you are into mineral and fossil. But your gabbro sample is probably difficult to use as a yardstick for comparison. It has too many details an...

Re: Metal Catalysts and Resin Beads
QCC, polarizer/analyzer can be used to reduce surface light glare of metal particles. In that case, your overhead reflective light source should have one polarized filter and the other filter should be placed after objective and before eyes.

Re: Haematococcus under different lighting methods
gekko, I may be mistaken, but I thought that one can remove any of those circular filter inserts from your Nikon phase turret condenser and put in DIY ones? Or at least you can use that empty bright field slot (if you don't mind losing regular bright field, that is)? With Rheinberg, you may take out...

Re: Familiar item, unfamiliar use.
Phil:
Great idea!
Of the items that you sent me, this was one of the things that impressed me most. Another thing was how well your packed the items.

Re: Haematococcus under different lighting methods
Great photos. I especially like the pol and DIC. I think your oblique photo can be even better. Maybe try pushing the stop off center even more (for more contrast)? Did you use COL or simple oblique? If you were using COL, maybe try a bigger central stop? You may also try that GUF/UGF filter (basica...

I saw some clear projector sheets for sale, but those are a bit expensive (and I don't need much). Surprisingly, OfficeMa...

Re: Metal Catalysts and Resin Beads
Well, please give it a try with what you have plus a LED flashlight or diffused camera flash. That way, at least you would be able to guesstimate if your LWD 40x can resolve the pores of catalyst? And does your LWD 40x says 0.17 (that means you need to put on cover slip)? Maybe suspend metal powers ...

Re: Metal Catalysts and Resin Beads
houstontx, You may need to use epi illumination (epi light source, polarizer/analyzer and epi objectives). Adding that to your personal Olympus scope will be expensive. I am guessing you need to look at pores of your metal catalyst (unoccupied pore = available catalyst site, occupied = not usuable)?...

Bill, You have sharp eyes and did some great digging work! In theory, both of the products that you linked should work. My concern for the adapter you linked to is: It is $20, as opposed to my branded adapter at $50. Does Orion charge $30 just to stamp its brand name? I hope they are of the same qua...

Re: Fish Tank Filter
Have you compared the biodiversity between your filter vs a plant from the tank? Filter may concentrate lighter floating protist, as opposed to sinking/attaching protists. I am guessing you will see a lot protists attached to plants as well. Such as hydra, ostracod, water bear and whatever that is b...

Sorry for diverting your topic houstontx.
