MichealG I’ve even thought of using those swift iPhone microscope adaptors on each eyepiece-a lot of homes have more than one iPhone living there.Then you could take 4K footage from each eyepiece-again would need to adjust lineups and tilt issues in post production-MichealG are you wanting a display...

Hello chrisimbee-nice kludge to get it working-is it possible to posts photos of the objectives used (especially the back side) I’m starting to understand some of the symbols relating to different properties on lomo objectives -looks like positive phase from the slight white halo around objects-they...

Hey MichealG sound like we’ve had a similar project in mind-I too have been thinking of this for quite some time-but for video-I put on demo days about compost/organic-biodynamic farming-I’ve always wanted the demos to not be “dry”-ie put some humor into it and if there were kids attending I thought...

krame I got the image off the Olympus website explaining dark field-variable dark stops have come up a few times in the group-and I’ve got another interesting idea to tease your brain!-what if you made a combo of variable dark field stop in the middle and on the other side an iris that just closes a...

Thanks for the reply dtsh-I’ll grab one off eBay and give it a go-I like having different types of slides to play with like deep well,cavity etc so it actually seems a nobrainer to just grab one-did you find they don’t dry out as quick as a standard slide and coverslip?

I just bought 20x and 50x PV WE dipping phase objectives from a member-there is a 80x PV WE version as well that I must have! If anyone has one they don’t use and wants to sell it hit me up throug PM-also want to collect all the dry PV objectives in the -h variety-negative phase-also the 63x PV in a...

So Sabatini the later pictures look way better-what did you do differently?-one downfall of the heine condenser is I often find it harder to see the phase ring compared to a turret condenser.

Hey krame great side hobby for microscopy-I don’t know how hard this would be to make but what about making a variable leaf dark field stop-photo below-they could come in different sizes for different filter holders 30mm-32mm etc-a continuously variable dark field stop-I guess it’s like an inverse i...

Wes-Either way they are interesting looking invaders! Is this done in DIC? Nice images and video.
Regards

Not only that Sabatini but COVID has shown that even viruses can be genetically’profiled’ and indicates was it COVID from Spain,or America or that cruise ship that stupid governments (ie Australia) let disembark leading to a 6 month level 5 lockdown for an entire city (Melbourne)-those microbes on t...

Hey Wes I wonder if the amoeba is infected or they are just food doing for a ride until big enough food vacuole is formed-or did the amoeba perish from these invaders
Regards Ross

Very nice elvis-saya! I’ve seen those red spotted ones before-they are fun to watch on an inverted scope as the seem too mainly bottom feet so you can see their mouth frantically scrubbing the bottom of Petri dish for food-reminds me of those creepy-Crawley devices that clean the bottom of a swimmin...

Hello-I usual just use normal slide either in inverted or upright-I used petrdishes but that’s for desired chaotic footage as the microbes have such free range in that much water-I want to do a series of vids of microbes dividing-problem is the normal slide often dries out before a microbes finishes...

Probably depends on the additives-a lot of drugs are water soluble and some are only partially so-so I guess some could be diluted then filtered-that’s how opiate addicts extract codeine from meds with paracetamol-as codeine is very water solvable but paracetamol is way less so-so they dissolve the ...

I’m always amazed at all the ingenious ways testate amoebas create a protective home for themselves-especially the type that perfectly arrange dead diatoms or microscopic mineral particles like master bricklayers and roofing contractors. Seems to indicate brainless microbes share Maslow's hierarchy ...

My slides look like that also-reminds me of soap bubbles...

Here’s a helpful tip Seta-When trouble with polarisers becomes a real headache I always take acetaminophen-preferably without potassium cyanide like they do in Chicago ...cool pics though-I’ve never gotten much into this type of microscopy but I can feel it calling to me from the near future-I’m on ...

Wow synnus that was a wonderful surprise to find today! I am so grateful to you-I was just thinking about the PZO the other day and thinking should I sell it-I may still but I at least need to see what it can do first! Do you use one of these scopes? If so how do you compare it’s DIC capabilities to...

G’day chrisimbee-looking for amoeba proteus was a big priority for me as well! Especially once I got some phase optics-I found some in a neighbours frog pond that had a bubbler to keep things fresh- but they are so friggin’ large you can see them quite well in bright field-and with just 100x-in fact...

Red_Green I think we need both streams operating at once-people into the natural world for its own merits and documenting the wonder and people who are into it to try to mitigate and reverse the damage humans have done in just 100 years. Maybe these political forces are informed/inspired by what the...

Hey Plasmid maybe apochronaut was suggesting another way of feeding your hydra-cheap-readily available-stress relieving-can’t see any downsides really..

I don’t believe any male microscopist who says they haven’t-and shouldn’t be hard for any female microscopist to find a volunteer I’m sure..

Red_Green love that pic of the lone strand of algae-finally found the word to describe these objectives-they have a neon look-very distinctive-seeing those insect pics I have to ask have you ever seen footage of the microbes that live in a termites gut that help them digest cellulose? They are reall...

That was cool Plasmid! Never seen one in real life yet but want to... fascinating creatures...those sad littles eyes peering out of the hydras belly...heartbreaking! But a hydras gotta eat.what was the magnification?

Howdy perrywespa from hot hot Houston-I’m from Australia where it gets pretty hot but I don’t think I could handle the high temperatures Texas gets! Did you get affected by that crazy winter snap that Texas suffered recently ? What you interested in with microscopy? Don’t be afraid to enter all the ...

David Hatchman Good idea in COVID times! It can be a good idea to keep notes on your jar pond and if thing go well you will be able to describe to other members who have had epic failures in trying this as well! What are you using for a scope?
Have fun ross

Sabatini just in case you don’t have it here’s a link to the heine system manual. I had a quick look and there describes adjusting lighting for the ortholux is done without the condenser in place at all and only inserting the heine condenser after the lighting is set up properly-it’s a good read any...

Hey viktor j nilsson-I’ve got Pv objectives and they don’t get that weird yellow fringing-first photo is Pv,type ‘h’ I suspect-second is phaco which have thicker ring than the Pv objectives but same problem-also has that fringing-I’ve wondered at times if certain vintage optics perform best with the...

Beautiful microbe Sabatini-I’ve got a heine condenser also and yours does seem to have this sort of yellowish chromatic aberration thing going on-especially on defined edges like the scalloping structure around the internal egg-is there any oil that has gotten onto the mirror part where the light ri...

Well brianjc in my opinion you can’t go wrong starting with pond life-it’s like the kindergarten of microscopy-or the three R’s in education-there’s just so many incredible microbes from just one type of ecosystem-or if you go to the beach collect sea foam and let it liquidise back to slush-wack a b...
