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-east 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?

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

You can low cost purchase a rubber bulb activator for all sorts of capillary tubes...but my capillary tubes, my 10 and 20 microliter glass capillary tubes sit in a draw, unused. If you have trouble with your pastuer pipetts bulb action being useless..blame the problem on 'crappy' rubber bulbs..those...

Thank you,luis, beautiful encounter. Do you 'image process out, do you remove :dust specs/ fibers/ media debris from this video sequence? How is it that the media this protist swims in seems so clear? Yes one small protist does swim by this organism..yet how is the imagery so clear? Thank you, luis,...

I use a glass platform for my slide, and for the rectangular cover slip..easy pick up of each from these raised platforms...of course if you are compiling a collection of target organisms for a wetmount slide..a second slide on it's own platform needed...time to time drink off waters from the 'round...

Going back and forth between the three bench images I posted..here are protocols I use to effectively 'round up' protists and meiofauna for constructing a wet mount slide. By using large rectangular cover slips ( 22X40mm, No.1, globe scientific inc., Paramus, NJ)..you can safely observe in over 80% ...

Hi, harry, thanks for visiting this thread. I always wondered about bitter cold Manitoba/Canada stream flows in harshest of winters...sure enough your Winnipeg/ Manitoba weather and news station stated from 12/23- to 2/24 Manitobans experienced near record warm 'winter weather'..of course with temp ...

Here ( image #024 ) is the eight (8) tentacle green hydra. Sure enough ( I always control water depth/ water film thickness under a wetmount slide cover slip..to not 'crush' meiofauna)...sure enough , this hydra is exploring and leaving the water film under the coverslip. For me I fancy this a chanc...

Hi all, this early 3/24..only one day of snow, below 30 degree-F temps..with strong 50- 60 MPH winds. I scooped sampled an area of my stream segment of the mesocosm. On the first wetmount slide prep I developed with pastuer pipet slups from the scoop sample jar...two (2!) Chlorohydra viridissima...t...

Elegant images, thanks for posting. charlie g

Thanks, microplan for this microscopy of a freshwater (sweet water!) female cyclops copepod. At 51 seconds into your microscopy..and onto 1min and 15 seconds..we see numerous single red pigmented eyes in the developing embryos mother carried in her ovisacs, before she was crushed to death, and her o...
