Another great catch + very nice video, though perhaps a little dark You will need a better input than mine, but I wonder if Mastigamoeba setosa might be a better fit than Mastigamoeba cf setosa given the description: "nucleus with some peripheral nucleolar fragments, sometimes with lacunae; cilium ...

At the beginning of the video I think the aperture may have been closed a bit much.
I can't help with the identification tough. As amoeba change their shape continuously it probably is a difficult task.

Thanks Bob, good tip on the aperture.

I've been through all (I think) of the amoeba examples on the Microworld amoeba site and this one is the closest match I have to this amoeba: example : https://www.arcella.nl/mastigamoeba-cf-setosa/ my video: https://vimeo.com/353171007 This creature has cilia and a flagella, but I'm not confident t...

Thank you everyone ! I found another different type amoeba in the same sample that has cilia and flagellum but I'm going attempt to ID on my own (at first) before I post the video.

The first one is definitely a ciliate. It's not a Paramecium , which have a prominent oral groove, but I'm not sure I can make out a mouth well enough to guess what it is instead. Note that while it might be less natural looking, often brightfield gives you better detail for recognizing them. The s...

Wow, just phenomenal !

This creature has been fascinating me for a few days. I took a small sample from the bottom of a "less than fresh" freshwater pond and have seen this in several of the slides I've looked at. Taken with a BHS BH2 scope, Nikon Z6 (FX format), 2.5x photo eyepiece, DIC. The first half of the video is wi...

Just wanted to say great catch on the second 'creature' https://www.arcella.nl/genus-mastigamoeba/ Mastigamoeba aspera looks like a possible candidate Thank you ! I have a vial of material from the bottom of a pond and I've seen that amoeba frequently. Its very fascinating and I have quite a bit of...

The first one must be a paramecium and the second some kind of amoeba ? This couldn't be Balamuthia could it ?

I'm new at this and am struggling with trying to ID things I'm seeing. Could someone ID the two creatures in this short video. The second creature shoots out some kind of long feeler, fascinating ! https://vimeo.com/352779967 and also if you could suggest some kind of reference to ID fresh water pon...

I'm having a blast

An excellent setup. SPlans yield beautiful images. And the video is very attractive, too! enjoy!
Is that a 100W halogen illuminator ?

Thank you ! Yes, it is the 100 Watt.

Hi Dan, you've got yourself a very nice setup there and the results look very promising! Your approach with the well slides makes it more difficult for you but at the same time you obain a more natural view of the specimens with makes it worth the effort. Most "great" plancton images are made in th...

Its been a fun few days setting up this new (to me) microscope. It is an Olympus BHS BH2 with Phase and DIC. I don't have any Phase objectives (yet) so I haven't had a chance to try that part. I have been playing with the DIC quite a bit. [ ... ] I'm having a blast :D What a tremendous start !! Tha...

First, I'd suggest you peruse this site: http://www.krebsmicro.com/ Charlie Krebs is the BHS-DIC Photomicrography Guru. Pretty much all of your questions are answered there. The projection eyepieces are designed to stay away from the outer edges of the field where image quality can be a bit less. T...

I forgot to mention that I purchased a second lamp housing and the necessary components to fit fiber optic lighting thanks to MichaelG's suggestion. I'm looking forward to seeing what effect the cooler lighting produces. http://www.microscopy-uk.org.uk/mag/indexmag.html?http://www.microscopy-uk.org....

wow, beautiful and professional video! congrats!! can you say a few words about your aquarium setup? Oh thank you ! Its a ten gallon glass tank, in my garage, with a small air pump and bubbler stone. I have about 5gal of pond water in it. Occasionally I get more samples and put them in. I really do...

Looks like a great setup. Can't see in the picture -- I assume you have the BH2 DIC condenser as well? Are those SPlans on the scope? As for the 1.67x - might try imaging with less powerful objectives to capture the on-screen magnification you want?? If there isn't a 20x Splan on the turret, that m...

I ended up getting a BH2 BHS that I think I'll be happy with. Looking forward to getting started.

Congratulations! Do post some photos of it in the My microscope section when it arrives. We would all like to see it.

Will do ! Thanks to all for helping ( my bow emoji didn't translate )

I have located a couple of Olympus BH2/BHS and Nikon Optiphot 2 scopes but before I buy I would really appreciate anyones thoughts on whether I might be better served with an inverted microscope ? There seems to be a lot of these on the used market. For examination and video recording (important to...

When I started my search for a used system, I initially thought it would be way easier than purchasing astronomy equipment (which I have done for decades). In fact, the opposite is true. I am really surprised at the complexity ,variety and sophistication that describes microscopy equipment. I have l...

. . .. Is there one standard BH2/BHS ? The BH-2 is a series name (following the BH microscopes from Olympus). At the time, this series had the highest market share among professionals. It was a very good scope, lots sold, and all sorts of system accessories. That also means a robust used market sti...

I really like your idea of the Olympus BHS. I've spent the last hour hunting these down and I'm wondering does BHS mean BH Series ? I see BH2, BH2/BHS, some loaded with accessories and some seem to not have the external light housing. Is there one standard BH2/BHS ? The repair support instructions ...

Thanks PeteM--

Thanks MichaelG-- any modern day variations of live boxes ? I love the idea. Also thanks 75RR- I would be interested in a system like that with an external lamp box or LED. I'd like to buy used. The astronomy hobby has a forum named "astromart" where folks buy, sell and trade their equipment. Does s...

Thanks everyone for your comments ! I really like the idea of an aquarium and I'm going to do something like that. So, moving forward.... What would be the best system for me ? I do want to take as high quality videos as possible. I have a lot of experience with Macro, wildlife and underwater videog...

Hello-- I have become fascinated with micro biology. My son lent me his Omax microscope and I immediatly examined a sample of water from the bed of an outdoor fountain. There were many Stentors and a few other organisms. After observing these for an afternoon, I became disturbed at the possible harm...
