Hello fellas -hope you don’t mind me jumping in to the convo- hey apochronaut (such a cool handle)-do you know of any Chinese 1000x infinity water immersion objectives with an iris? Also what’s the tube length of chines objectives ? I’ve got one infinity scope-Leica DM750-does it matter that much to...

My two cents Harold-phase contrast shouldn’t be judged in imaging critters that can be easily seen in bright field-it often makes the image worse as TonyT’s photos show-bright field will always do a better job-sometimes phase can give a nice enhancement of say inner structures of ciliates and nemato...

Hey smollerthings I found this also with certain 90-100x objectives -I know it’s not the best image but just a casual look I can find it enough visual information to keep wanting to explore the slide without the hassle of oil-did you try any digital sharpening in post?

G’day Sienna Naylor -you sound really eager to learn more which is itself a great place to start👍 don’t worry- everyone here has been at the stage of “I don’t know anything yet but really want to start!”- enjoy this stage of your interest in microscopy-it gets very exciting and thought provoking ver...

Once in a while you get a nice surprise-I’ll be able to use the Petri holder on the Labovert also which are almost impossible to find without a Labovert attached-I’m excited I can get my phase turret aligned again-been getting wonky for ages. Probably sell the Olympus photo eyepiece as I seem to be ...

Hi folks-really lucked out with this lot-$600 in very good condition with dovetail mount and working Petri dish holder (what?)-but got a lot more than was on the listing-heaps of extra objectives and eyepieces (including a fat 30mm 10x for my cute little SM-M Pol that came with a 6x) ,long intercept...

dtsh-interesting post-never seen images from AO scopes-the achromats have a nice subtle contrast and colour to them-and a sort of “soft sharp” which is nice on the eyes-the image of the “orifice” is interesting-the subtle contrast sort of makes you look harder at all the detail-do you have any photo...

Yes dtsh the egg photo was from wiki!-I wasn’t trying to suggest they are related just that I have seen them before but didn’t realise they were eggs-I make high thermal compost (let it get to 65 degrees before turning to kill pathogens and seeds-it’s mostly very motile bacteria/fungal hyphae at wor...

dtsh you could be right-I’ve noticed these eggs in the compost brew-photo below-not a lot but I thought they may have been a fungal spore or even a diatom that has brown chlorophyll-I really need to read more about species rather than just look at them-dyslexia makes it hard to read for long though....

Calling BramHuntingNematodes I was brewing compost tea and found this nematode with the longest tail I’ve ever seen-video link below-you’ve probably seen longer-it seemed to be the type with the boxy shaped mouth with “fangs”-excuse my very basic descriptions-do you know much about Polyphenism in ne...

Found this in my frog pond today-seems to be a spirette type body with two flagella whipping about like a cowboys spinning lasso…I do like the weirdos…
Anyone know what it is?

I imagine the old natural selection comes into it a lot as well-the way a lot of flagellates have that ambling “duck waddle” probably keeps them a moving target as well as bumping into food sources-has anyone seen the flagellate that from my observation seems to grab food and attach it to its back-p...

My two cents-I wonder if simplification is key to good modern field scopes-my CK-1 inverted only has course focus but if wheel is big enough it’s quite usable even at 400x-also I wonder about alternatives to X/Y stage like a floating stage you just gently push around-I think mechanics need a real ch...

Hello peeps-below is my new cute little Pol scope-same size as the SM-Mesical scope-came with objectives,condenser,and light source but no compensators (first red,1/4 wave etc) which fit into a slot in the back of the nose as indicated by the red arrow in the photo-I’ve seen some sellers on eBay wit...

I can personally concur it works well with RuPauls’ “Stinky Dinky” from his/her first album…

josmann that last video was really rad!-like a little space city with flying vehicles racing all over-was that time lapse? Also what were the really long strands wriggling around the algae? I need to put some effort into 1000x oil immersion again! Lazy me…

Nice vids josmann-I’ve got tadpoles in a big bowel with water plants and found these a couple of weeks ago-and noticed the moving crystals as well-I’ve been more interested in micro critters but algae are starting to really catch my eye more now-ditto on Davinci Resolve-been a using it for a while n...

Very cool microcosmos -whoever says “disco sucks” is a fool! Are these transmitted light or reflected light? If transmitted light are they semi opaque or quite see through specimen?

Hey snmbsc I trust the forum can handle gross! In regards to micro plastics I wonder if studies have been done about microbes that break them down-I guess UV does too.. and mechanical action-Also I’ve always wondered about the tonnage of tiny particles from all the soles of synthetic shoes entering ...

Hey Leitzcycler-haven’t had time to be on the forum much-the Neo illuminator I think only works properly with Neo objectives which have 25mm thread instead of 20mm rms-I’ve got my Neos set up on an old beat up BH-2 (interchange nosepiece) with the newer (BH-1 era) Neo illuminator-to use Neo on the E...

Hey allgren you have a decent clean up job ahead but it’s a very nice scope when all is working well-I have one-they come also with trinocular head or blind photo port without eyepieces if you want to take photos. You can put a vertical illuminator on it to look at minerals in reflected light-put a ...

Welcome snmbsc- this is snot a very nice introduction to yourself! Jokes aside sorry to hear you got the loss of smell post covid-must make eating weird-I’ve read articles about naval fluff mostly being blue-do you wear a lot of blue shirts?-the fibres are strikingly flat almost like microscopic aud...

Thanks for replying-I’ve tried to find articles but they all seem to be behind paywalls-not that I’m against paywalls necessarily but budget not in shape-I’m just always curious about non standard uses of specialised objectives-from what I did read there are different types of dispersion objectives ...

Been reading a bit about these-just curious in the spirit of using techniques in applications that wasn’t intended for can these objectives do anything interesting in observing microbes? Apart from showing your paramecium has asbestosis?

Hello-I can concur with 75RR-I love phase and originally would observe phase for everything-but a lot of pond microbes can look just as good in bright field or darkfield-but when you flip to phase and massive numbers of soil bacteria suddenly show up like magic…it’s well..magic! I now it’s not possi...

No insult intended MichealG-and none taken-I laughed at my idea of over complicating things with camera and screen once you pointed it out. Making me realise my brain can go down some silly rabbit holes especially when I’m getting tired. Have you experimented with any stereo camera setups lately or ...

Oh forgot Phill Brown I agree-been using my iPhone torch quite a bit on a leitz SM-medical scope that I’m waiting for a light assembly to arrive from eBay-they have a pretty good brightness and colour temp-I find at night though electric scope lights a bit overstimulating which mucks up my sleep so ...

Thanks for the input everyone-Alexander I think it is a rotating stage-it looks like it moves forward also on two dovetail rails-maybe sideways as well..must look it up on the Olympus museum webpage-MicroBob apart from those really nifty Leitz single knob course/fine focus set ups (which I love) I’m...

What a der brain I am! It’s amazing what you don’t think of when you don’t think!
Thanks Scarodactyl !

Hello peeps-I’m thinking of getting the Olympus scope below as a traveller-has sturdy box etc-my only problem with scopes of this vintage is the neck/back strain bending over to look down the eye piece-did they make add on angled monocular eye tubes in this vintage a bit like you’d see on any modern...
