One Ugly Family Portrait

There must have been a dust bunny over the Ipad's lens, making this the worst photo I've ever taken, but do to a request, I publish this, with great embarrassment. I am moving, and the packing process in the den is a nightmare. To all the members who have had a hand in my getting this far I offer my...

Re: Wanted-junk 25mm objective

Re: Wanted-junk 25mm objective

Grasshopper feels like his chain is being pulled when asked to explain to the master, but jumps at the chance to do so. Nikon infinity obj's are 25mm, and 23mm go straight through the turret hole. Sadly, I just used the scope to diagnose my cats cutaneus histiocytoma cyst. The vet will back me up, I...

Re: My new stereoscope

Sorry, can't help you there. My scope is binoc only, even though I have the hardware to
hang my Nikon on it. I have not tried diffusing my Ikea lights. Experience can be a humbling
thing, as much effort as I expended to get 120X, I use the 7 to 30X most often.

The base is really heavy, and is not required for 'flexible lighting' setups.

Re: Wanted-junk 25mm objective

Now I feel bad, you offered a cap, but another member beat you to it. His are infinity. (figure that out)
Now I have a pair of useless 23mm to resell.
Well capped in Seattle,
Thanks everyone

Wanted-junk 25mm objective ** I got them**

I need to plug one hole on my E600 turret, and I don't need any more objectives.
The plastic plugs are rarer than hens teeth. Considering a rubber test tube stopper.

Thank you Carl, I'll check it out. May only need one as I'm contemplating a 4X objective, maybe
my supplier will also have a 2X. Sure an expensive way to keep dust out!

Research Pipette

Is this a reasonable deal? It's graduated in 50 micro-liters . Primary use is for transferring fluid in
rinsing diatoms.

Field test for diatoms

Can anyone suggest a method for quickly analyzing beach sand for diatoms? I will have a microscope
of as yet undetermined properties. I am working on a mini-centrifuge, based on a very small cordless drill.
I have no nets or filters of any kind. Grateful for any help.

Re: Kayak microscope recommendation

Good thread Fan, we are both looking for the same scope, right? Scanning for diatoms
in the field. If it works in a kayak it should work in my checked luggage. I have no parts
to complete a project scope. I need to use different search words to get better results, like
yours.

Vintage is what I've been searching for, also, but I need something light enough to
fly in checked luggage. These fine old instruments weigh a ton. My options are to carry
a 25lb scope, or a few lbs of sand!

Re: Bad sand samples

That is what Charles reported. I scooped right from the surface as the surf flowed
out, which I guess is wrong. Next year, at Kauai, I'll be better informed, and prepared.
Do you agree that I should stay well above the surf line and dig down?

Bad sand samples

It looks like my beach sampling method was wrong. I scooped the wet surface sand as soon as the
water receded. I got a cup every other minute, and a good dousing in between! However no diatoms
are showing up. How should I do this in the future?
