The small
house spider, Badumna longinqua
- Paul Hampshire (Australia) shows
some interesting features of a
common spider on the microscopic scale.
A close-up
view of the common wild flower
chicory
- Brian
Johnston (Canada) shows that there is
plenty to explore on the macroscopic
and microscopic level of flora we often
take for granted. The 'Cool
light' LED ring light for the Coolpix
digicam is used to good
effect.
Design
considerations for the ideal Köhler
illuminator. The white LED as a
microscope illuminant
- John
Walsh (Australia) provides a valuable
overview of this topic and shows a
practical design for a lamp, illustrated
with typical results.
Plant
sections in brightfield and polarised
light
- Ian
Walker (UK) shares an attractive gallery
of images of prepared slides taken using a
Nikon Coolpix 4500.
Size is a relative thing
- Ron Neumeyer (Canada)
describes and illustrates a useful way of inserting scale
bars into a digital image using readily available software.
My favourite flower:
the scarlet pimpernel
- Paul James (UK)
explores on the macroscopic scale the attractive features
of an increasingly less common wild flower.
Safe
microscopical reagents for amateurs.
Mounting microscopic subjects. Part 4
-Glycerine jellies. Part 5 -
Mountant summary
- Walter
Dioni (Mexico) concludes his series on
safe and accessible reagents for
enthusiasts, by discussing mountants based
on glycerine jelly. He also chooses
the best mountants for given subjects from
those he has discussed in the
series.
Heath,
hedgerows and ponds in the English summertime
- Ian Walker
(UK) shares images and notes on some of the insects and amphibians in
his north of England garden and nearby countryside in midsummer.
Trials using
an external zoom digicam (Sony S75) on a
microscope with a reversed SLR lens as a
relay lens
- External
zoom digicams with large diameter lenses
are becoming increasingly popular, but can
prove tricky for photomicroscopy, both optically
and mechanically. Dave
Walker (UK) assesses one cheap but
effective relay lens with a typical
digicam of this design.
