Aphid Proboscis
Will looking around the garden for subjects I came across a plant with a few plant lice on. I found the proboscis interesting but it turned out to be a difficult image to capture as the background to the proboscis in my mount was the body of the Aphid. I had to get the light right and then make sure...

After many pollen images something a bit different.
Moss leaf, 20x objective, DF illumination, 51 image stack.
Thanks for looking,

Re: Microtome?
Ran some numbers through the price calculator - the cutoff seems to be 29Kg At that weight the charge is $459, using Priority Mail Express International when you go over (to 30Kg) it jumps to $1036 as your only option is Global Express Guaranteed. So how much does a 820 actually weigh? Note: Came a...

Re: Microtome?
Insane shipping costs. Just for fun I checked from Sweden to South Africa. I tried 35 Kg, box that is 40x40x30 cm (big enough to fit a microtome) and was quoted 3020 SEK which equals to US $320. Promised delivery in three days (!) Just as a comparison... Weird why shipping from US should be more ex...

Re: Microtome?
Among the many 820's I can find on eBay I have found 2 that will ship to South Africa, in one case the shipping is $1850, via USPS and the second quote was for $2250. The variation is somewhat surprising as is the high cost of both quotes. Have you tried pricing USPS shipping yourself? If you can p...

Re: Microtome?
That is a replica of a Spencer/American Optical 820. Perhaps one the most classic rotary microtome. I have one myself and they are really good. However, I would rather buy a used original spencer 820 in good condition than to trust a replica. Perhaps they are great, perhaps they are not. I bought a...

Microtome?
Hi everyone. I am looking at acquiring a Microtome, rotary most likely. There are many options on eBay but in most cases shipping is really expensive. Some of the cheaper and faster shipping options are from places like India, mostly for new equipment. Would something like this: http://www.ebay.com/...

Pollen - Clerodendrum splendens
Hi Everyone. A quick trip around the garden this afternoon produced this pollen sample. - Clerodendrum splendens (Flaming glorybower) a native to western Africa, is a woody or semi-woody evergreen vine or running shrub to 12 ft long, that climbs by twining. The leaves are oval, to 7 in long, and arr...

Re: Olympus BHMJL
I forgot to mention: obviously, camera imaging is more sensitive to vibration - you may not see vibration during visual viewing or magnified live view, but it can still make images not sharp. But I am sure Rudi has the basics covered. I mentioned vibration, as some small basic BHMJ models with pole...

Re: Olympus BHMJL
Rudi, I meant vibration while viewing through the scope. You may have that at 40x and up, if base is not stable enough. A few of my mineral samples are 40 mm thick. I like viewing them with 1x objective. Photographing is better done with macro lens at that magnification, I agree. Aha, ok, will look...

Re: Olympus BHMJL
Not that you shouldn't get a incident based light microscope or anything but (just in case you didn't know and apologies if you do) you can view small objects via reflected light without a dedicated microscope. I do. I just use various lamps/goose neck things to light my subjects. I'm not saying th...

It denotes the "large" stand with the additional illuminator and condenser below the stage as apposed to the smaller model with a stand that looks like a stereo scope stage. It is the one on the left in the photo from the man...

Re: Olympus BHMJL
You may need to mass load the base, before putting on a 100x. Look at a loose diatom with your M40x and see if there is much vibration. For thick and big minerals, say at 40 mm thick, you may need a 1x objective with SHORT working distance (if you need 1x objective at all). Or your pole height may ...

Re: Fitting a Lomo 1.4 Aplanatic condenser to my microscope.
zzffnn, my preposition is to make a threaded ring that raises the top lens to a much more reachable height. It'll fit between where you would normally put the top lens and acts as a height increaser. I don't think just raising the top lens is a good solution as you then change the distance between ...
