Bob, the washer is hardly visible in my photograph... but it sits between the the second and third item from the tip.

I am having a really bad photograph day, but maybe there a some pointers in this; I have not been able to unscrew the rear disc, but I can see that the back of the lens's metal has a pronounced chamfer

smollerthings; Have you tried putting a piece of card / paper/ other fine-grained white material over the mirror ... you will get a much less harsh light into your eye. you need Illuminate the card with a some kind of mini table light ...Ikea used to do one.. you move the light closer or further to ...

front group out. On this one the bevelling on outer face doesnt go all the way to the glass , but the bevelling on the inward facing end goes all the way to the glass.
(there is also a faint circular witness mark on the outer glass where it has been cleaned/scratched with the nose shroud on)

RAF camera sells a flanged adapter that will fit directly into the top of the Lomo's framework in place of the prism head, you will need some extension tubes between the camera and the adapter but this seems a bit less precarious than dangling a heavy camera on the end of the eyepeice tube. Less cha...

-Cigarette lighter fluid (not the gas) is really good at softening the hardened grease and it doesn't have oil in it. Leave it 5 ot ten minutes or even 20, if 'whatever' doesn't want to move ...apply some more fluid wait another ten minutes and try again. Have plenty of paper around as the grease is...

Self adhesive material can be tricky... if you get it wrong you can have an annoying problem. If you want to try something else; 2mm thick EVA foam sheet ( a sort of children's craft material ) is not too bad, the stuff I got off amazon in A4 size needed 'airing' for a day or two, due to some solven...

These are quite nice and ergonomic .. I have some black craft rubber foam inside it to kill reflections :

I am always slightly curious whether reflected light photos even if they are taken through a microscope are considered to be macrophotography??? Here is a stacked photo taken with a bloomed 16mm Beck objective through a Beck 3228 [with a very wrong tube length!] : Beck Bloomed Uncovered 16mm on Beck...

I have a new Win10 computer and thought that I would download a copy of ICE for it.
However the Microsoft page says that the download is no longer availble.
So suggestions for good alternatives would be useful

A couple of other simple arrangments that work
And a photo:
[Stacked with Zerene]

Maybe it is now a bit over-developed. It started life like this: 60mm lens clamped on watson frame cropped.jpg which was handy enough. Here is a pic of how the back of the Utebit quick-release plate was filed away to let the tube-clamp jaws fully open: arca mount part filed away.jpg I have had many ...

.... and if you are trying to photograph discreet unmounted things eg small dead insects, you could try putting them into the bottom of a half-ping-pong ball ... this can be rested on a microscope-slide sized piece of plastic or cardboard with a round hole cut into the middle and lit from the side (...

Half of half ping-pong balls are sometimes easier to get into position 'after the event'
[That is a bit of a wooden skewer attached with holt-melt on the right hand side one]

Use scissors as much as you can when cutting the ping pong ball --or they will turn blood red.

I have had a lot of fun with this :-) There is a cheap (~£7) but strong clamp that will fit onto most medium-sized monoular tubes (up to about 42mm diameter) onto this one can attach an Arca style camera tripod plate once the clamp's 3/8 inch reducing bush is removed. Clamp and washer and generic Ar...

I have tried this (on a Meiji BM1) and to be quite honest the photos were quite poor :-( If the purpose is to get nice stereo pairs of small stationary things then a really good way to get them is to use an ordinary microscope, do a focus stack, and then ask the software to create a 'synthetic stere...

You do need to turn the knob slowly otherwise you will end up doing a 'click and a half' rather than a click.
Not very sophisticated .. I push it away from the focussing knob with a finger when racking the microscope down.

I have a little clicker made out of a bit of an aluminium soft-drink can (the stuff is not as sharp as you might at first think.) I cut mine into an L-shape ( a bit like a piece of angle iron) with a pair of scissors and have one flat side of it attached flat to the microscope body and the end of ot...

(No tweezers though )

Very nice projector:-)
Re. the inverted slides; there are very large diameter circular coverslips sold on ebay [from China] I bought some and they were pretty clean.

Ha, just to say that I misunderstood what was going on: If the internal surface of the ring light is blacked out, the exposure time more than doubles ..so the light isnt just going straight up and into the ends of the glass slide and then travelling along to the midge, quite a bit is of it is going ...

Maybe it has a use for looking at the upper surface of opaque objects(?) but I dont suppose that many of these are put in mountant.

Maybe one day, childrens microscopes will come with LEDS embeded into the stage !

I havent tried one, but there are tiny (1/10, 1/20 inch) SMD LEDS being sold with wires attached to them ..lights for model-makers. Because of the little hotspot I had in the midge photo, above, I tried resting the glass slide directly on top of the Angel Eye, so that the light came up from undernea...

Here it is under the stage: The black bit sticking up out of the condenser mount was a (failed) attempt to make a dark-well.

The 'Angel eyes' headlight rings mentioned by dtsh in the 'microscope adaptations' section ['AO cycloptic illuminator'] seem interesting: The set I got were 'Qasim 1-Pair White 70MM 60SMD COB LED Halo Ring Angel Eyes Led Car Headlight with lampshade Cover 12V 24V DC' from Amazon [£10.50 for a pair]:...

Thanks! I didnt know that 'Angel eyes' even existed, they look quite useful.
I have a set on it way

Here is the hacksaw, cardboard, hot melt, sticky tape of a month ago : The the whole light unit was sawn in half lengthways.
