Hej Håkan,
I've admired your work for quite some time. Good to see you post on here as well! Amazing and inspiring photos as always.

Viktor, in Lund
Thanks Viktor! Good to see a Swedish microscope fellow on here. Not many in Sweden that I am aware of with this hobby.

Re: Rotifer and some algae

Wow these are really good!! Especially the last one. I'd be very interested to hear about your setup with the hope of improving my own technique. Cheers! Wes Hi, the setup was a BX51 with a UplanSAPO 60XW (Water immersion) for the first and last image. The rotifer was shot using the UplanSAPO20X. D...

Re: Rotifer and some algae

Wonderful images hkv. Thanks for sharing. I'm intrigued by the rotifer image in that, despite stacking and stitching, there is very little evidence of movement. Is there a secret you're willing to share?? Tom W. Thank you! Well, the body was still, but the head moved. Therefore the head is barely v...

Rotifer and some algae

Hi there, been lurking around here but not posted for some time. I thought I would share a few of my recent images with you. Not much time to photograph anymore, but was out sampling a local lake recently and managed to get a few samples. First time I manage to get Botryococcus! I remember 75RR had ...

Hi Håkan, really great images! Every time I see how beautiful and detailed nature is it becomes more and more difficult to understand how badly we treat it. It's nice of you to decribe the amount of work and capability that was neede to make these images. So we are not disappointed when we can't ge...

Re: Wetland Cillates

Thanks Bob, What you say has just made me think. So does a larger drop of water create a larger space between the slide and the coverslip? Within reason. :) Yes, for sure. Large drop, large gap. The surface tension of the water lifts the glass sort of. I use Microbobs method as well. Add water with...

Re: Diatoms

Your DIC images are great again! Where in Sweden do you live? I was twice paddling in vintage folding kayaks in the area south on Västervik with my family. It was very impressiv to move between these many small uninhabited islands and then stay the night in tiny tents on one of them. I live in Stoc...

Re: Diatoms

Fascinating! Is the red photo - fluorescence ? the same diatoms as in the first DIC photo? Yes, fluorescent light. The red is the chlorophyll auto-fluorescing. Not very exciting as an image as such, but it clearly revealed 4 strings of chloroplasts in each diatom in the colony. If you look at the D...

Looks like Paramecium for sure! Great shots! The first one seems a bit stress as it is about to burst. Maybe because of pressure from the cover glass.

Diatoms

I was out with the boat collecting samples from a local lake and was surprised to get a huge amount of diatoms. Many which I have never encountered before. I dragged it after the boat for about 5 minutes just below the surface. My daughter was more interested to use the collecting device as a hat. I...

Have you tried a cross-eye stereo of any of them ?
No, I have not tried that. I have to struggle to see cross-eye stereo at all and mostly fail in doing so... Therefore, I never enable that feature when stacking. Would be neat to see these in 3D for sure.

Cyanobacteria - Gloeotrichia

Long time since I posted in this forum so I thought I would share a few images. I was out boating in august and noticed some small "algae" floating on the surface of the water. It was like small hairy balls and I took a sample in a beer can to check them out. To my surprise, they were not algae at a...
