Hello microscopists, from vernal pool at top of highland steep foothill, I encountered a diatom (average size as freshwater diatoms go in my observations) with many very small and tightly adherent diatoms attached to it.

I have not used my oil-immersion objective (100x,NA1.25,Plan,Reichert/Austria circa late 1960's) for months, I had to dig about in my file cabinet draw for the immersion-oil bottle!

The lower magnification image is: 40x objective+10x eyepiece. In both the oil-objective higher magnification images ( for each I changed the substage condenser settings just a little,each image with different settings)...in both the highpower images, I did not oil the condenser to the bottom of the wetmount slide(please don't tell anyone I was so lazy as not to do this?!!). I am still handholding a small 'point&shoot' camera to the trinoc vertical port and with camera set as:ISO, collecting my images 'quick and dirty' as some would say. charlie guevara NJ,US

Source spring'09 meltwater builds to literally 'vernal water falls' in key steep highland foothill rockfaces. This was an Easter Sunday,4/09 hike.

The simple collecting of a few specimen bottles of water, added to pleasure of the hike. charlie guevara NJ,US
