Re: Free Nikon microscopy webinar

Reminder, it's tomorrow. Nikon run a number of webinars, worth a look.

A number of sources of webinars has come to my attention in the past months, Gresham college is a good one :

Re: Stink Bug.

They're here in the UK too - just. First found on luggage a few years ago, they're being monitored in Kent where there's fruit production. It's thought our summers aren't quite warm enough for them, but climate change has brought us some warm ones.
I imagine we'll see them establish.

Re: Microscope for crystal photography advice

For biological use the SP150 looks like a sound choice. For higher magnifications, which you will probably want, you'll use the condenser and turret to swap objectives, which your rail is lacking. The "advanced" polarising kit which gives you a rotating lower pol would be the one to go for. The dark...

Very nice - what "tube" lens are you using on the UM-2?

Re: Interesting stuff

I've been offline a while, and missed this. My uncle was a watchmaker, his workroom had a lifetime's collection of materials like Ray's. He used his "set of turns", which I think he'd made himself, rather than a full lathe. I made a couple of replacement pinions and bushed a couple of tiny watch pla...

Re: Sphagnia fluoro

Beauties, but do you have any idea why some of the chloroplasts don't seem to be "turned on". Bleaching?

I thought "Royal Blue" was tradiitonal exciter, ~430nm, though I expect the difference would be quantitative only.

Re: Fluorite with masking tape

Interesting, and well taken. I imagine heat, or something may have diffused into the more active sites on the structure, during or after its browth, but I have no idea what. It doesn't seem to be common? UV result may reveal something because it's the impurities which fluoresce. Pure CaF2 doesn't. L...

Re: Autumn mantid

I like that a lot. The composition with the orange parts probably isn't one you'd find in a book, but they add warmth and contrast to the animal.
I think I'd be tempted to clone in a mirror-image antenna!

Re: Macro gear for a beginner?

HI Flevioma.
A 600D is fine
I'm moving this to "Beginners macro". Do have a look there, there are some good answers.
How close Macro do you want to go? (In field-of-view terms?)
