Does anyone have an answer to Interference's A, B or C question?

That's an outrageous bit of kit John and at a really good price!

Let's see some sections soon.

Cheers,
Steve

Great photographs and really interesting to see the different lighting conditions.

What a beautiful species that is!

Hi, I have been looking at some composted plant material and most of the tissue has gone completely but I have noticed that the vascular bundles seem to be the most resistant. Here is one example cropped from a 20x view. The ground tissue has all gone and this is the fraying end of the vascular bund...

Nice shot CG.

Your TEM looks about the same vintage as the SEM that I used to use... I wonder how much one of those would be on eBay now

Cheers
Steve

Merci Seb.
Je pense qu'il est fascinant de voir jusqu'au niveau des cellules qui sont si vieux.
Vous avez été réveillé tôt le dimanche.

Thank you Seb.
I think it is fascinating to see down to the level of cells that are so old.
You were awake early on Sunday!

Hi All, Here is a photo from another one of my antique J Lomax slides. This one is one of the slides where the reverse of the label has the company name. As such it is probably quite valuable but I think they are fascinating and beautiful so not for sale! The specimen I selected from this slide is ~...

Somewhere between art and science!


Any of your photos could go on the wall Seb.

Cheers
Steve

Wow Seb!

Salut Seb, vous peut-être raison. Je vais devoir mettre des filtres polarisés sur ma liste!

Hi Seb, you may be correct. I will have to put some polarised filters on my list!
Steve

Thanks Jim, Hi QCC, For normal petrological studies I would say yes, polarised light was the way to go. However in these coal ball sections it is the organic remains that are of interest rather than the mineral matrix. Have a look at this page: http://steurh.home.xs4all.nl/engcalst/ecalstam.html#coa...

Stunning photograph!

Very nice Seb,

The first one is simple and strongly pattered. I like the detail of the nucleus in the last one.

Hi All, Now that I know how to use my DSLR and trinocular microscope together I took some photos of a slide to see how it looked. Firstly the slide: J Lomax (1857-1934) was the son of a miner in Yorkshire in the 19th Century who saw plant fossils in the debris from the mines and started to look at t...

Well they would do but the females often breed through parthenogenesis (ie they produce fertile eggs without needing fertilisation - like stick insects). In memory of my studies of ostracods many decades ago I keep a tank of them in the greenhouse under the bench. I must get some of that water under...

Cracking photos Jim.

The first one particularly shows the 'scars' where the adductor muscles attach to pull the valves closed.

Factoid about Ostracoda: they have two penises

Cheers
Steve

Thanks CL,

I too like the look of those bulbs. They are not too expensive either (for something that will last for years).

Interesting technology: lots of little LEDs in a strip, coated in a fluorescent compound so it glows as a strip rather than little dots.

Cheers
Steve

I didn't realise the top image zoomed when I was looking at it on my phone - doh!

I would agree with everything that Fossildude19 said there. A nice section.
Cheers
Steve

3mm is probably too big for an ostracod fragment so "Shelly debris" is probably what I would have put it down as.

What was the suggestion on the other forum?

Cheers,
Steve

What size is that?

It looks very like a fragment of an Ostracod shell.

Cheers,
Steve

"I have ordered a C Mount adapter 1x which is shown as having a M28 thread at the other end. " I think it's a 1" thread on the adapter, which is C mount so I have ordered a EOS-C adapter. The center port is quite different in diameter to the eye pieces and I don't think that is one of the accessorie...

Thank you Appchronaut!

That is really interesting info and the sort of detail that I just wouldn't have found outside of a forum such as this.

Cheers
Steve

Very nice Seb.

Cheers
Steve

Very good photos Seb!

Thanks CE and Bill, It has a missing battery door (£5-10 on eBay) and the SD card protection switch was stuck on 'Protected' so it would not take photos with a card present. This would not have been an issue as it was going to stay on the mic and would have worked fine on Live View, just saving to t...

Hi everyone. I have just received my new Canon 1000D and it was a 'repairs' job off eBay. £10 on parts and some careful fiddling and it is now working! I downloaded the Canon software suite and tried Live View for the first time. Bearing in mind that I don't have my relay lens for my new mic yet I b...

OK I'm getting there...

I have ordered a C Mount adapter 1x which is shown as having a M28 thread at the other end.

Any idea what adapter would link this to a Canon 1000D?

Cheers
Steve.

Yes Apochronaut,

You are also correct in that the 40x is marked as .66

The head does have a 48-50mm dovetail and a 24mm lens - what does that tell you about it?

Cheers,
Steve

Thanks 77RR.

Is the 40mm port a common size? Just wondering if there are generic tubes that will fit this or whether I either need to buy a OEM part or make one.

Cheers
Steve

Hi Everyone, I'm not used to working with infinity objectives my trinocular has a top port like this: http://i109.photobucket.com/albums/n71/stevestevephoto/microscope/75B28DD7-18AF-47C6-9819-853A8656A034.jpg It's a 40mm diameter dovetail with a 28mm diameter tube below it. What is the best or most ...
