Re: Some recent shots at 2.5x-3.5x of Live Jumping Spiders

I used the Olympus em1 mark 2 with the MC-14 teleconverter, 20mm of Pixco extension tubes and the Olympus 60mm macro lens. Godox 250TT Speedlight on my hotshoe, and focus bracket mode/stacking mode depending on image. I also added the Raynox 250 or 202 on one or two of these. stacks are 40-110 imag...

A ring light can achieve this quite well, if you get the distance from the subject right. Do this by trial and error.

This was done like this;

first class work.
Pass that on to your supplier as well. Beautiful.
Yes, they are nice. Ernie Ives produced many slides such as this, with most having sections in 3 planes.

If you want some George, contact me.

Nikon E400

Anyone got an electronic copy of the Nikon E400 user manual?

I have searched online, and the E400 Pol is widely available, but not the straight model.

Thanks.

These are gorse shield bug eggs (Piezodorus lituratus) https://www.flickr.com/photos/66189529@N08/47928205027/in/datetaken/ If the implication is that 1of1snowflake's eggs are the same species as what's shown at Flickr, then I have to say I think that's probably wrong. The eggs shown at Flickr have...

Many of the stink bugs (or shield bugs as we tend to refer to them in the UK) produce very interesting eggs, either in terms of patterning, sculpturing, or indeed how they are arranged on a leaf, as a 'raft' on in paired rows. In green shield bugs, Palomena prasina, the female will find a suitable p...

I think I have the thing sorted now, via a rather peculiar route but started by someone outside of the forum suggesting this objective was one for the inverted Biostar model. I hadn’t sussed that the optic was from an inverted, so that was a bonus. Someone mentioning the Biostar Inverted had me look...

Pretty sure it is a hoverfly, of the Eristalini group, which have a distinctive prominent loop in the wing vein. You can see this as a droop or drop in the vein. This includes both bumblebee and money bee mimics. Could be the later, of which Eristalis tenax is very widespread.

Just guessing John, is the old PSU an American Optical by any chance, like that for the AO 20?

AO x20 objectives

I am sure there is a sensible explanation for the fact that I have two AO x20 objectives, both phase, and both plan ache NA 0.50 types. However, on my AO 10 and AO 20 one performs much better than the other. The better performing one is Cat No. 1212 and the leseer of the two a Cat No. 1223. They do ...

I have that polariser too, and I can tell you that it fits on my Labophot-2, but doesn't fit on the Optiphot 1 I have. The shape is different.

I am guessing the Labophot 1 and Optiphot 1 shared the same fitting.

butterfly egg arrangement

The Victorian microscope slide makers used great ingenuity in making impressive slides for wealthy microscope users to own and delight in viewing. In an era with no radio or TV, it is sometimes suggested that gathering round the microscope was akin to gathering around the piano. This is one such sli...

There are also two stands as I said in passing and yes with illuminators but everything has been in storage and the working condition of components could be uncertain. The long bellows on one looks damaged for example. I'll post the photos if you are interested in making an offer for the two sets o...
