Hand sectioning; plants

In this month's Micscape Magazine there is an interesting technique: http://www.microscopy-uk.org.uk/mag/indexmag.html I have tried to hand cut sections using several methods, none worked! This method works at almost no cost. Here is a section of a Hydrangea flower stem. I have only zoological stain...

Re: Help needed: DIC components necessary for my Oly

Possibly irrelevant!
I have an Olympus BH2/BHS with DIC; very simple setup, explained in the Oly brochure.
Images likely not as good as more modern DIC's but may be worth the hassle your having

Re: Earthworm

This one and your sunflower X-section are nice images. However, they would be more interesting if there was some interpretation of the various morphological parts. I guess what I am saying is that "art" is good but I would prefer "science"; why not both ?

Re: First photos and image editing

It is obvious that you are not happy with your Cyclops image; and I am a loss as to why it turned out so poorly.
I took this image years ago with my BHS and DPlan objective and 2.5x NFK. I have forgotten what power objective I used.
This is the quality I would expect you to get with your equipment.

Re: Dissection needle prototype

In some species the females give the males a rough time. The male aedeagus has to negotiate this chicane, in the ductus, that is equipped with a double set of shark's teeth; only to be greeted by spines in the bursa.

Dissection needle prototype

Male moths have an aedeagus (equivalent to a penis) which in many species has 'armature' Here I have dissected out the spines of a single male Cabera erythemaria moth. Each would make a fine dissecting needle if I could figure out a way to mount them on a handle. Spines are chitin (a large, structur...

I have several of this type of laundry basket with a finer weave, great for enclosing living plants + caterpillars; perhaps you could get one locally. https://www.ebay.com/itm/Laundry-Bag-Pop-Up-Mesh-Washing-Foldable-Laundry-Basket-Bag-Bin-Hamper-Storage/362971428063?_trkparms=ispr%3D1&hash=item5482...

Nikon's 10x finite (cf, Nikon CFI)

I feel somewhat of a Luddite here where many of you have switched to infinity optics. Constantly having to convince myself that I don't need to switch from my finites. So it is always nice to see a subject taken with an infinity lens that I can reasonably compare with a similar subject taken with my...

Re: Egg Papilio machaon update I & update II

The probability of it surviving to an adult in the wild is about 1% - that's nature!
