yup..I recieved your PM...but my reply message to you simply 'does not fly'..what's up with this ? all the best, to all. charlie g

kblackwell..still in our 'active topics' collection of threads..please visit 4/11/24 thread, by garyjm: "Dark Field Illumination"...very specific info on DF microscopy..apochonaught/phil clearly explains DF microscopy.

Hi, kblackwell, as apochronaught/phil has posted many times..it is with your higher magnification/ higher NA objectives that you require a 'dedicated dark field condenser'..and adjustable iris in the objective optic itself. With lower magnification/ lower NA objectives you can DIY fabricate opaque d...

Hi, garz, an extremly talented 'diatomist' advised me to rub/ clean the already apparently clean slide with a tiny , tiny pinch of diatom containing toothpaste before using said slide for mounting target frustules.

Please consider giving this a try ( and please brush your teeth), charlie g

Alas, the 1993 data on : 'earth frozen water'...the data on ground water..demands updates..updates are cause for all our global concern.

Happy Earth Day, 2024...microscopy world views enrich our appreciation for fresh waters available to living things, to communities functions. ' the oceans contain virtually all of earth's free water. 2.5% of the earths water is frozen in ice, or sequestered as ground water. The water in lakes and ri...

Hi, kblackwell (OP), and apo. Kblackwell..please 'google' : "Mushroom, the journal of wild mushrooming"...lots of content regards to ID..and lots more! This journal...I may still have their issue devoted to :'using the compound microscope in mushroom ID'...if I have it..I can mail you copies of the ...

Hi, rorshack..I'm late to your thread. Please consider low cost : "Diatom Lab", of Stefano Barone..for wonderful permanent slides which you may use to calibrate, to understand the optical performance of the variety of your optics. On several occasions I have purchased slides from "Diatom Lab"..diato...

Thanks for this microscopy report. I wish you tried a higher magnification objective at some part of this wonderful image sequence.

These protozoans to my sense, are ciliates. thanks for your microscopy, charlie g

I have a large selection of : finite 160 tube length/ 0.17 objectives for low cost..extremely low cost sale, Eric. I am also trying to clear out ..extremely low cost Oympus C inverted microscope. Do tell what microscope ( finite/160 TL, 0.17 coverslip) objectives you might want to enhance your micro...

Michael G., I am cluless, a 'neoludite regarding links'..but thank you for producing the link for Judge. happy spring'24 to all.. fingerlakes/US 4/8/24 solar eclipse was 'half a dud for us'( at our fingerlakes/U S location). It was wonderful to view on the south-west horizon an ominous darkness char...

Thanx for posting this encounter, eric b. .

If your stand is: 160 tube length ( a finite DIN stand)..is: "160/ o.17 "engraved on the objectives you now have?

charlie g

Welcome, eric b., and congrats on your scope salvage..and 'bear encounter'. That second image captures an interesting illumination contrast method for your meiofauna ursine 'bear'! Please share: what scope objective+eyepiece combination used? What method of illumination of the slide? BTW..do you enj...

Hi, judge, please visit #2 group of 'active topics' posts: "under the 1/24 ice'.

Hi, gary, and jackieone...I and a few other forum members noted the 'failure of PM messages to properly launch'...and more a concern..our forum administrator no longer replying to 'PM's" to administrator. I hope all is well for Oliver, if this is a financial spindown of this forum..well I understand...

Welcome to this great forum, amoeba-X..no doubt I've enjoyed a post or more from you in forum: "cloudy nights.com". It's not the 'thread size' you need worry about..first step is to list the specs engraved on the turret of objectives you now have..what are each objective speced as on their respectiv...

Ooops, sorry I missed your kind visit to this thread, and thank you for your speculation,zzffnn. All my wet mount slide preps have rotifers and entrapped air bubbles...I am observing the wet mount slides within minutes of 'dropping the cover slip' on the sample droplet. No other rotifers..either on ...

Please, don, please do not hold to idea that all life ( protists, meiofauna, and our scale: megafauna) do not go on all seasons..yes even under the ice ( as I often cheer about). Where you reside the ecology thrives in winter. Think of the neighbors of yours whom enjoy winter: 'ice fishing'...organi...

Green wavelengths in our light spectrum, the wavelengths human eyes are most sensitive to ( our retinas if 'normal retinas'). I think this a reason green filters are often found with vintage ( ?tungsten bulbs, halogen bulbs illuminators?). My circa 1980 Nikon-Labophot-Pol came with a 'yellow-goldish...

Thanks for sharing this microscopy, macnmotion. Terrific to see this behavior. That first foram at 40X-oil was a quite tiny organism ( as far as forams are discussed)..wonderful post, thank you. charlie g

Elegant and gracefull your first ciliates...and childrens author/illustrator: Dr.Seuss would be inspired by these ciliates. Excellent images of gastrtrich and the rotifer meiofauna in the second panel of your rural water ditch neighbors.

Thanks for posting these encounters, apo. charlie g.

Hello jlknight..it always helps to offer context of collection site, then low magnification ( 4X/10X/20X magnification image captures)....lastly an oil-100X image of the organism being observed. ( eg: eye-lashes of a cat,dog, rat, horse not as useful for organism ID, as a context (where organism col...

Similar to my pleasure in feeding family and friends, and coworkers since teenage years..I respectfully observed this green hydra capture both a cladoceran water flea, and a large nematode. Please go back to the higher magnified tentacle image and for yourself..see if the clusters of endosymbiotic C...

Happy spring'24..first hydra bud of this year encountered 3/30/24. All surface ice in the mesocosm gone. It was 12/25/1702 that Antoni van Leeuwenhoek sent a letter to the Royal Society in UK, describing observations of active hydras Antoni collected. I am deeply puzzled by the sparse facts stating ...

Harry, thanks for another terrific thread, and especially thank you for the tip, and the link to Dr.Martin Kruetz's "Real Micro Life" website. charlie g

Hi, sure squints, neat thread you have going, terrific solutions. But I suggest you consider the application and removal of dust covers be part of a process. Dust cover, plastic cups over eyepieces, and rubber air-puffer. At shut down, air-puff the oculars , air puff the cups, place the cups over oc...

Welcome, saltydog. You need to (low cost, well organized book) get a hold of 2016 book: " Insect Microscopy", by Dr. Andrew Chick...nothing vexing about andy chicks instructions and materials to use.

BTW, I find it charming that you mention: 'insects and bugs'. happy spring'24, charlie g

I hope all is well for Oliver and family.

Hi all, many many protists have strategies for controlling their solar light environment..with out terming it thoughtful behavior strategies...we 'neutrally?' term such behaviors as : tropisms. Some flagellate protozoa ( eg: Haematococcus pluvialis ) actually move their internal pigments to shield i...

I have experienced a lot of the: PM functions do not work. I hope Oliver is well ' family healthy and happy. charlie g
