Olympus BH2 LED Lighting

I'm going to post a few images showing how a couple of LED alternative lighting systems for the Olympus BH2 BHS and the BH2 BHT compare with the factory fitted Halogen bulb. The BHS was fitted with a 12v 100w system which provides plenty of light for most photography in all techniques, really the on...

Re: Light Source for BH2 BHTU

Dave, could you compare the convenience of the Saul's and Retrodiode's illuminators for continuous illumination in the same microscope? I'm interested in light intensity, regulation, light quality and mainly ability to set Kölher. Just curiosity because I have both continuous and flash illumination...

Re: Light Source for BH2 BHTU

I do have Saul’s hybrid LED/Flash for the BH2 and it is excellent. I’ve had really nice results using it in darkfield where using short duration flash will give plenty of light and is fast enough to freeze any action. The LED side obviously enables you to frame a shot when using flash, I tend to use...

Re: MJKZZ Rail and Canon Mirrorless Cameras

Just thought I’d add - Helicon remote will control some rails (WeMacro, Stackshot....) and fire the camera shutter via the USB cable (PC - Camera). This is very useful for those cameras, like the Canon M50 mkII, that don’t have a cable release connection and rely on a bluetooth remote. I believe tha...

Re: Light Source for BH2 BHTU

Hi, You are correct in thinking that you can’t use the 100w lamphouse on the BHT/BHTU. I have Olympus BH2 BHS and BHT models and I use a Retrodiode 10w LED illuminator on the BHT which is good for light hungry techniques like polarised, darkfield and phase contrast and will certainly be fine for fun...

Re: Chondritic Meteorite section

The image is very interesting and beautiful. Thanks for sharing. I am also making large images of archaeological pieces (sorry, until it is published I cannot show anything, and it is not strictly macro either) and I cannot find a suitable software capable of handling 140 images taken with my Canon...

Re: Algae galore

Very nice! I especially like the last two. Adding a little Calcofluor White fluorescent stain will light up the spirogyra cell wall under UV but I don’t think the result would have looked as good as your images.

Re: Chondritic Meteorite section

Thanks for that Mark, I didn’t know the full story about the Murchison meteorite. I see that there is a lot of effort being put in to finding freshly fallen meteorites as soon as possible after impact, before too much contamination (you can even set up a sky camera yourself and join the network), bu...

Re: Chondritic Meteorite section

Here are some images of the detail using a 10x and 20x objective.

Re: Chondritic Meteorite section

Thanks Rik. I wanted an image of the whole section, the lowest magnification that gave a nice saturated image using transmitted x polarisation light on my particular set-up was my 5x objective, so that is what I used. I have no use for a 50,000 x 30,000px image that the stitching process created. Th...

Chondritic Meteorite section

Hi, this is a section of a chondritic meteorite that was found in Iran. It's a stitch of around 300 photos taken with a 5x objective under crossed polars. The original image is 50,000 x 30,000px so the 300kb limit here means you can't see much detail at all. I've put a much larger version here https...

Re: Cleanest microscope slides for D/F microscopy

Hi, I clean the slides and coverslips in an ultrasonic bath using a solution of Decon 90, then wash in de-ionised water, then leave them in diluted acid for 5 minutes, wash in de-ionised water again then rinse with ethanol. I then store them in ethanol in plastic slide containers until I want to use...

Re: fluorescence metoo

I use a centering device that screws in to the nosepiece, like this, https://www.ebay.co.uk/itm/Nikon-Epi-Fluorescence-Arc-Lamp-Alignment-Centering-Microscope-Objective-/363039981049 it’s probably worth investing in one but if it is roughly correct I can often centre and focus by looking at the fluo...
