Dear Charlie: Wow, fantastic images of the Rotifer... great exposure control as well as composition... You were able to get a few images freezing the subject,...

Mike, I agree that I made my set of new dealers too large. But no dealer can afford to let a buyer use a new scope for 6 month and give him 90% or more of...
Charlie, I agree that the sheath can be very difficult to see. Under darkground illumination you can often see it, if faintly. Your pictures are excellent -...
Dear frez, it work fine but i think you can compress more your files without quality loose. In this moment I'm experimenting DIvx and Xvid ad I think they work...
Hi Graham, You raise an important point in regard to brightfield illumination (I consider oblique as BF). I my view, the various forms of optically induced...
Can any of you tell me if the "later" versions of the Zeiss intermediate tubes or Optovars (for the Universal/Photomicroscope) have an arrangement by which...
Hi Gary, Don't worry too much about whether it has the dovetail or not - I have made several of my "non-dovetailed" condensers into ones that will fit into my...
Hi Mark, Thanks for the encouraging words. When I first bought my Labophot, it didn't have a condenser. I found one in the bottom of a box of junk I bought...
Hi John, Thank you very much for the Seaford sand sample. I have uploaded an image of the sand, which is primarily quartz. From the map I would guess it comes...
Hi Gordon, What do you think the majority of , Zeiss, Leitz, Leica, Olympus, Nikon, Meiji, Wild, AO, B&L scope frames are made of?, Zinc Diecast Alloy, Cast...

Mike, Most of the ones I have worked on are cast iron or brass with some bronze bearing and steel and brass shafts. Cast iron is used in some bases of older...
Then I would guess that all of your scopes are 45 years old or more, not modern scopes as such. Most all modern Leitz, Zeiss, Olympus, Nikon, Meiji, Leica,...
and trim the excess from your posts. It is really not necessary to re-re-re-re-re-recite all the previous messages in a thread. Not everyone has a T-1 line. ...
Dear Mike and Gordon: In my experience I found the older microscopes are far superior in craftsmanship and materials. I have talked to some of the heads of the...
G'day Ron The sand comes about 1 mile from the Patterson River. No, no goldmines this low. Most come from the moutainous areas.(goldmines). I would love a...
I just have to tell someone. A while back Frez posted a bunch of phase contrast photos. I was completely captivated by them. A short time later I happened...
... short ... I ... a ... <snip> ... the ... Well done! Looking at phase contrast for the first time is a real gas. Amoeba in particular look sharp. Your...
Hi Keith, Well, one Canadian opinion, but not mine (I live in BC, Canada). I had the pleasure of using a black Ortholux system for many years, before moving...
Hi Gary, No there isn't anything wrong with your setup. A proper phase condenser is just an expensive but convenient method of doing exactly what you did. As...
Hi Kevin, Thanks for the information. As soon as I read what you said about the green filter, I remembered that somewhere in my treasure hoard, I have a bunch...
Hi Graham Thanks. It could be a Coscinodiscus radiatus. A pity mine is "broken". After having seen quite a few on the net, I am rather pleased with my example....
Jim, Thanks! Actually this particular rotifer posed quite nicely, hardly moving anything once fully extended. But you're right, most rotifers pose a...

Mike, After reading my lesson on aluminum alloys and weighing some parts and getting the specific gravity of them I believe we have two different perceptions...
Dear Ron: I agree with what you say: I said .."".We are enjoying at present the last of the great microscopes with the all around best of materials The fact...
Keith, I agree with your sentiments regarding the lack of longevity with our modern instruments. I work with microscopes daily and was horrified when a new...
Hi Keith, I wish I could make a living using a microscope! At any rate, the recent history of microscope manufacture from 1960 on ward is extremely complex...
Hello Ian, Although you do not name drop, there are those of us out here that know EXACTLY which manufacturer you speak of! They have had problems with ...
Hi Gordon, I do not intend to prolong this seemingly never-ending debate. In fact, this will be my first and last post on the subject. I just felt a need to...
