Thanks Icthy, billben and micro-pix. The Elaeagnus scales are very beautiful. They are also amazing with DIC. Not sure how they are removed from the leaf in such good condition. I've seen a few other slides of the same subject where the scales look quite knocked about and damaged.

Excellent. The detail in the first and last shots is exceptional for a conventional light microscope.

Sensational of course. The first two are real wall art, despite liking the colour in number one, I prefer number 2 myself.

Looks like some ants are being a nuisance as well as the rain. :D

Same technique but this time the subject is the stellate hairs (trichomes) in situ on the leaf cuticle of the shrub Deutzia scabra . Another Victorian slide by the same firm. Both these slides were once probably part of a larger set of slides showing off polarisation with the microscope. A fairly ne...

The Heine does Darkpol and Phacopol

One of the nice things about the Leitz Heine condenser is how easy it is to move from dark ground though oblique and phase contrast (with suitable phase objectives). If you add simple polarisation it adds an additional lighting dimension. I added simple pol to my Ortholux, with a rotatable polariser...

Interesting. You can sort of see the contribution of the different components; picric acid: needles, alanine: plates, and red staining from the fuschin. Looks like you may be over exposing a bit. The highlights are quite blown out.

PM sent re a couple of items. Pity I don't live in Sweden. :( :lol: I agree that quite a lot of the Zeiss stuff would also fit a WL.

Thanks Sumguy and grgh. Rik-- That explanation, with the excellent analogy of the tilting CD is very clear and helpful for me, thanks. The description and ray diagram in the second Micscape reference is also very useful and clear. The way in which the Heine works optically is easier to understand in...

Thanks Chris and mawyatt. Chris- no worries about the animated GIF. See my PM. If you'd like to make an animation of all 12 please do. I thought there were 14 but it turns out I'd managed to duplicate a couple. Here are the rest of the images. http://www.photomacrography.net/forum/userpix/718_X4_plf...

Fireworks with the Heine Condenser

I've been playing with my newly acquired Heine condenser. One thing it does really well is low power dark ground illumination. When it comes to choosing subjects, there is no doubt that the Heine and diatoms is a match made in heaven. These images are all taken on a Black late production Ortholux 1 ...

A couple of suggestions. If you really want hay, head over to your local pet supplies store. They will have hay in small bales as rabbit food and bedding. They may even have a split bale they'll let you have a handful or two from. There's nothing magic about hay though, I've found plenty of interest...

Thanks very much, some really useful information there. Another friend also sent me a pdf of the original Leitz brochure for the Heine, which is very helpful. Fan, I love the creative use of Lego. :) I have several of the Lomo objectives mentioned, and will try them with the Heine. Any chance of som...

Thanks nanometer. I took loads of pictures in that session and in that one picture the flies just posed beautifully.
