How does your Hero 8 differ from a Hero 7 Pro?

That could be a Quenox part, rebranded as Vello, by the New York City importer , and retailed by B&H Photo, the only source Google and Vello will find for my queries out of Germany. I traced Quenox to China a couple years ago, but am not finding them at the moment. I mention this in case both adapte...

I will take a look at that. It is has both constant voltage and current 10-turn pots; one comfortable with soldering could replace a 10-turn pot with a remote single turn control.... That might not be a bad idea as those small, PCB trimpots are typically rated for only a couple hundred rotations.

The CMT1412 I have is doing decently with a 25mm x 25mm x 15mm heatsink. I have left it on for a couple of hours as I'm testing to get stable temperatures.... [They] are what I get at various points on the cob, heatsink, etc while it's running and have been trying to keep the highest I measure unde...

The CMT1412 I have is doing decently with a 25mm x 25mm x 15mm heatsink. I have left it on for a couple of hours as I'm testing to get stable temperatures, but this one hasn't been put into an instrument yet. Specs state 38v max, 34v typical; mine is running at 33.2v down to just above cutoff to ke...

... I believe that chip/driver combo for the first design is pushing around 6w; the chip can handle more, but the driver is the limitation. I'm currently working on another one that's running at 33.2v and consuming just over 0.3amps, so just over 10w, but there's much work to be done on that one un...

+1. You can also refine a separate box after you get a chance to use it, and not worry about further wear and tear on the microscope. You may find a small, sloped console box to be to your liking. Here is one that houses something different and perhaps more complex, a remote shutter / USB switch, I ...

But the 380T manual makes it seem so easy! V. Mounting a camera attachment Place the eyepiece adapter into the trinocular camera port on the top of the microscope and mount an eyepiece camera (not included) directly on it. If you would like to use a C-mount camera (not included), unscrew the top rin...

If you play some more with the LED ring light at high magnifications, you may discover it is more blue than you thought and introducing chromatic aberration . Another issue, not explicitly raised in that thread, is that you may find its strong blue peak is reducing both the resolution and contrast a...

Indeed, the current, OM System OM-1 is mirror-less and micro four thirds.

... Trying to find out the name of the mounting system that the OM system camera lineup uses. A micro four thirds lens mount if it is digital (and current!). Should you wish to experiment, MFT has a short enough flange focal distance for direct (optic-less) projection out of a 1" c-mount camera por...

Brochure says for the second knob: "Mechanical brightness control without variation of the light’s color temperature" so I presumed it is an iris. For the small switch it says: "Switch for optimizing the illumination", I suppose it is the one you mention, hopefully the supplements are included :? I...

Does that one really have an iris? (I have a predecessor which I like.) Instead, I think your unit has a switch to insert or remove some supplementary optics. supp_optics_lever.gif The use of the supplementary optics ensures that you will achieve uniform, high intensity illumination even when using ...

Mine smelled more like the epoxy ash I remember from some erupted, industrial control electronics that had been struck (or nearly struck) by lightning.

...I got a used halogen fibre light and noticed two things straight away ; with a large heavy base unit one end of the flexible light is sort of 'pinned' and so getting the lighting end manoeuvered is more of a fight. The second thing if that is the power unit has been working somewhere not too ple...

... Also, FWIW, extensive use of halogen bulbs well below their rated power accelerates tungsten deposition on the glass. https://en.wikipedia.org/wiki/Halogen_lamp#Halogen_cycle .... Yes, but it is often the case that the bulb life is still lengthened at lower temperatures - just not as much as yo...

An iris lets you dim the output, without lowering the brightness temperature of a halogen bulb, at the cost of shortening its life.

... Are a pair of Zeiss W-PL 10X/23 appropriate?...

They work for me when contracted to their limits.

Just a thought. The flange focal distance of the Canon EF-M mount is only 18mm vs. 19.25 for MFT. Could the less sharp images and (extra?) strong vignetting of the M200 indicate the 0.330-inch spacer places its image sensor some distance above a C-mount's usual image plane?

... I came to the conclusion that whether the adapter seated fully or not was moot when using something like the D10NCL that has no optics - final focusing is done on the camera screen anyway. I didn't get stuck at the point of looking for an adapter I could not find, or trying to make one, but jus...

I can confirm the anti-shock option on the E-PL1, E-PL3, E-PL7 and E-PL8 all work with a stereo microscope acting as a somewhat slow, manually focused lens. The E-PL7 was the first to have focus peaking (from the E-M1) to help with that. The E-PL9 and E-PL10 manuals no longer mention anti-shock whic...

The Panasonic GF5 that took the first picture has no EFCS to reduce its shutter shock.

What microscope, and what magnification, specimen to sensor?

You might ask for a quote from tequipment.net (see REQUEST QUOTE under the price, then VIEW QUOTE, ....)

I have read that Motic has a competent Drawing Device. I believe model 1508.3 would be the right one, p/n 1101005900092, originally for the Motic K500/K700.

Thank you. I am curious how it will compare to a standard Wild head and a Wild or old Motic photo tube.

So, woo! A Wild/Leica standin trinocular head for a very affordable price! The eyepieces that came with it aren't great but I just got a pair of Wild 15x/17s which are very nice and perfect for my needs currently. I'll probably go to 10xes if I pick up a 1.6x objective for the system. Do you have a...

That is quite an improvement. I repeated my earlier 31X image with a Schott halogen ring light and it is noticeably better, especially when you flip between the images. I picked up a Schott KL1500 for cheap that I will try to convert to LED. I was planning to use a high CRI neutral white LED nichia_...

I could not find a U.S. quarter, so I used a just slightly larger Swedish krona. First the head of Carl Gustaf at 6X m7a_6x_left_6000K_ring.jpg Then some detail on the back at 31X m7a_31x_left_6000K_ring.jpg EDIT: Here is the back, again, but this time illuminated by a less oblique Schott halogen ri...

Thanks guys. I found them after disabling an overeager ad blocker.

The coin images may show less LCA if they were shot through a 20X/13(?) eyepiece.
