These are great!

The "auto stacking" with the Olympus bodies and that lens is amazing.

Freshwater plant. ID?

This is a freshwater plant that I found in an old sample kept outside. I'm curious if anyone might have some ID information. I'd like to learn more about this species. The cytoplasmic streaming seen through the microscope is remarkable. Here again I am curious about the round "spiked balls" flowing ...

"botanicals"

This is the time of year I like to explore inside flower buds that are not yet opened. The Camellia at my front door is usually one target. That what you see in the first three pictures. The forth is the inside of a Clematis bud, Here illuminated with UV, the pale green/yellow of the stamens take on...

Great shots.

For some reason I never thought of sugar being so colorful with polarized light.

Saul, This particular dome was half of a clear plastic Christmas ball "ornament" purchased from Michaels (hobby arts and crafts). It come in two sections so people can fill it with their own decorations. Here I have very slightly spray painted the inside surface with a matte white paint. (Very light...

Some cameras allow you to choose an "exposure simulation" mode for electronic viewing instead of always trying to show the scene as it would look if "properly" exposed. Apparently this is not a choice on the G6, but there seems to be some type of "work-around". See this thread: https://www.dpreview....

Rik and Pau and others have done a yeoman's job in explaining the problem. Their advice is sound IMO, and it is an "alignment" issue. I'll add a few other thoughts based on some things you said. I used this same combination several days ago for an afocal video shoot and there was no vignetting at al...

Volvox in darkfield is hard to beat! Soothing to watch.

Lacrymaria "hunting" is fascinating in the opposite way... bizarre, nasty, aggressively predacious. If I was shrunk down to protist size they would be terrifying!

Very nice photos ! Can you share technical details/technique ? I used a white plastic dome with some LED lights I made (not the Ikea light seen in the picture. The Ikeas are great, but for me not enough light output when using a 50/0.50 objective when heavily diffused): http://www.krebsmicro.com/fo...
