Here is a low powered view of the epidermis of an onion:

Here is a view of a single cell at medium power:

Don't know about this but could you get a low power view of a banknote?

Or maybe Richard could get something from the web...

. . . might THIS Suffice Luke?

. . . Banknotes: EURO & U.S. Dollar



. . . Albert - when you look for that Butterfly - 'Most' of the time you can find them already dead and in Excellent condition - just a Suggestion ;)

Nice Specimen works, again Thanks Sir!

Good detail on those notes you have there Richard... I was thinking perhaps seeing the texture or the 'structure' of the note itself (would this be considered 'high power'?)

EDIT: Great shot of the leaf, Albert, hope to see more pics soon!

Best Regards,
Luke.

. . . Luke - as much as i would love to show a 'Structure' of said notes - Regulations

from the United States Secret Service Rules 'Do Not Allow' me to


- i am quite capable of displayin' extremely 'high resolution' - though NOT on these Boards - sorry mi friend Rules are Rules ;)

. . . using an Edmund Scientific Lens Resolution Chart for Modulation Transfer Function - by Norman Koren





< snips re: Chart above >

Details of calculating 50% MTF - (Modulation Transfer Function):

1. The 5mm Koren 2003 lens test chart designed to be printed at 25 cm long (50X magnification) was downloaded from the Koren website and printed on semi-gloss paper

with a Epson 1270 printer at 1440 dpi. Charts are trimmed and mounted on the Edmund Scientific Test Chart as shown:




2. The chart is photographed at a working distance that is 1/2 the recommended distance so that the entire Edmund Scientific chart can be photographed for resolution

and determination of 50% MTF. It is also possible to detect lateral chromatic and other aberrations from the same test images.


The distance from the chart was calculated at d1=(M+1)f where d1 = lens to target distance (mm) and f = lens focal length (mm) and M=25.

The reduction of distance by 1/2 requires that lp/mm figures read off the chart be adjusted by 1/2 . . .

@ Albert
I have an idea for a cheap alternative to a microtome
as you will be embeding the sample in wax try a cheap disposible razor to get your thin section,don't know if it will work but worth a try!!!
probibly the single blade type would be best.
Old enough to know better(but)still young enough not to care

Updates will begin again late tonight.

@John,
It is worth a try. Thanks for the advice and I will give it a try and see how it works until I can get the blade that I need.

Carchesium:
Kingdom: Animalia
Phylum: Ciliophora
Class: Ciliatea
Subclass: Peritricha
Order: Peritrichida
Suborder: Sessilina
Family: Vorticellidae
Genus: Carchesium

Carchesium is a sessile, peritrich ciliate. It forms a colony of hundreds zooids, diameter of a few milimeters. Each zooid has an independent myoneme and therefore it can contract independently.



{note: the stalks did not turn out too good in my image, but here is a pic taken with the same scope, but with a different sample:

Here's something that's causing problems in the great lakes: Cladophora

Cladophora is a branching, green filamentous alga found naturally along the coastline of most of the Great Lakes. Research in the 1960’s and 70’s linked Cladophora blooms to high phosphorus levels in the water, mainly as a result of human activities such as fertilizing lawns, poorly maintained septic systems, inadequate sewage treatment, agricultural runoff and detergents containing phosphorus. Due to tighter restrictions, phosphorus levels declined during the 1970’s and Cladophora blooms were largely absent in the 1980’s and 90’s.
Kingdom: Plantae
Division: Chlorophyta
Class: Ulvophyceae
Order: Cladophorales
Family: Cladophoraceae
Genus: Cladophora'
