Re: Objective repair,need help

Hi 92111,
The strange colour you are getting from your smartphone will be a colour balance problem.
I don't know what the light source for the Diavert is, I guess halogen.
Your phone is probably set to daylight.
Just change it in the phone's menu.

Hi Hans,
Yes that is the diameter of the shells.
Thanks for the ideas about the group they belong to.
That's an interesting website you have must have a better look later on.
Cheers

Re: Swamp Biscuit

Thanks folks Hobbyst46, that is levels of skill way beyond me, I don't have the gear or ability to even separate it from all the other "crud" in that very small sample. Let alone do all the clever stuff I read about in the recent thread on cleaning diatoms. Bruce, Arcella was sort of my thought but ...

Swamp Biscuit

Hi folks,
Found in a slow moving stream in a freshwater wetland.
Haven't seen anything quite like this before.
Found 2 in the sample.
Thoughts folks ?
Cheers

It came from the bog

Hi folks, Another freshwater denizen I can't pin down. Living in the detritus and silt on a freshwater pond. There were a few in the sample. Generally slow movers but some moved quite quick at times. No signs of cilla. No shape change. The green things inside were constantly circling inside the "bod...

Hi folks, This has become a bit of a thread hijack, but an interesting one. Up to an hour or so ago I had never heard of the AO Polanret, what an interesting machine.

Hi Gary,
Did you ever show any more of the " lighting contraption"
I have a similar project sitting in random parts in my head at present.
I'd be interested to see how you put your ideas together.

Re: Genus Simocephalus

I make mini aquariums out of .2mm thick acetate and put the critter and the glycerol in that, then a cover slip. The internals are still moving around but with some luck you can time the shots to have the bits in the same place each shot at the sharpness level you are working at. I use the aquariums...

Hi Rod,
Sorry to take so long to get back to you.
Out of the loop for a few days.
I transferred it to Glycerol.
Slows things down a bit.
I don't use it much, but find it really useful for these critters.

Genus Simocephalus

Quite a common critter in the wetland that I'm getting my water samples from.
4x acro, over 100 images in the stack, probably overkill, but it's the best internal detail I've got to date.

Algae ?

Hi folks,
Haven't seen anything similar to this.
It wasn't moving.
In the rubble in the bottom of a fresh water animal trough.
Some sort of brown algae ?
40X achromat, 6 images stacked.
Thanks

Re: Wild M20 Service Manual

Just to finish the saga off.
Fixed and working better than since I've had it.
Hardened bits of grease stuck under the "direction changer"
Took the stage of, cleaned and regreased.
Happy it turned out to be an easy fix.

Would still like a service manual if anyone spies one on their travels.

Re: Wild M20 Service Manual

Update and ideas. The good news is it's not the plastic gears, they look fine. I pulled off the side panels beside the x / y stage knobs and realised that if you push the stage right back you can see the whole of the shaft and the bottom of the gears. This also let me what was causing the problems. ...

Re: Wild M20 Service Manual

Hi,
Yes had had a look at that page.
Also looked at Ebay, the prices for a 2nd hand stage are more than I paid for the microscope, then add seriously high freight and 15% GST when it gets here, thats not an option :)

Hi folks, Does anyone have an M20 service manual you wouldn't mind sharing ? I have an exploded schematic view but not sure it will help me much. I need to get to the innards of the stage.
