I've been slowly assembling a finite scope. I was previously using an AO Series 35, but I acquired a scope for it's objectives and found them attached to a binocular Series 15. The 35 and 15 are design wise pretty similar in appearance and both are 34mm parfocal 160mm tube length mcroscopes; where t...

If you are intent on parting them out, I can use a couple of parts. I have one that must have been serviced at an outboard motor shop.

I am indeed wanting to part them out, I need to condense my collection and these are just in the way at this point. What parts are you looking for?

I have a couple of Microstar IV scopes which are missing parts and/or in rough enough shape that there's no point in saving the stand so I'd like to strip them to compact my boneyard a bit. Do any of you know of a thread, site, etc which details the assembly so I don't need to risk destroying one to...

I've seen the odd discussion here and there about travel/carry/storage boxes for microscopes, I currently have a couple of them, 3 factory and one custom made; all with a variety of time related damage. I believe the general concensus is that the storage cases are just extra bulk and not especially ...

I'm not familiar with that scope, but I have handled similar Japanese scopes from around the same time period. They usually perform reasonably well with good optics, though probably not plan. The price seems a tad high to me, but not outside the realm of reasonable assuming everything works.

I had no idea but I have seen it on other forums. Maybe the question is too easy? The problem is that the tech is getting better; it's pretty trivial these days to programatically parse a simple question and get the answer. At the point you start tripping up the program, humans tend to be failing a...

This is an old issues, yes. I raised it some years ago https://www.microbehunter.com/microscopy-forum/viewtopic.php?f=8&t=8276 What I suggest is to have a question at the time one registers. Something simple yet relevant to the hobby for example "Which part of the microscope do you look through wit...

It's hard to balance vetting new members and fighting spam, if you make it harder for the spambots to get in, you also make it harder for new members to sign up. The issue isn't helped by the fact the spam gangs often use compromised machines to run the programs which trawl the internet for forums a...

The dovetail on those condensers is a slip on, fastened by two set screws. Under it is a neck of just under 37mm allowing the condenser to be used in non dovetail condenser sleeves of 37mm or larger if you put a larger adapter ring on it. I think originally, it was designed to be used on B & L as w...

This ring/collar came with my darkfield condenser, but the manual doesn't mention it and I'm not even sure it belongs with the DF condenser. It has an insider diameter of approximately 1-7/16" (36.5mm) and an outside diameter of around 1-9/16" (39mm). The ring is complete aside from a single hole ne...

I would expect 'white' but at a higher colour temperature than the LED and which would be variable. I suppose one advantage of an LED is that the colour temperature is fixed for a particular device. But that colour temperature will be determined by the stimulating/blue wavelength and the stimulated...

I usually get a nicely binned high cri Cree high power single die led and hook it up myself all the parts together might cost $50 you would therefore not find the same on a $200 new microscope, particularly if it had been manufactured ten years or even five years ago. I do the same thing. Sure it's...

Anyone can enhance imaging with a computer. I think that's cheating. The computer produced the final result but not you. Would it not be the same as saying "The filter produced the final result but not you"? There's definitely some skill and understanding required to process images and get good res...

I need to develop an application in a short time, but I do not have enough specialists to successfully complete all tasks. I am interested in outstaffing services. What are the terms of IT outstaffing as a service? Entirely unrelated to anything this forum does. Kindly ask your programmer to tweak ...

I use a pre-packaged LED driver, LEDdynamics A009-D-V-2100; not the cheapest option, but I get 8w and dimming with no flicker.

My eyeglasses and oculars are not friends; I end up mostly viewing digital images, and forfeiting the head was no great sacrifice. I certainly understand that, I find these days as I use the camera more and more, a monocular design as I have one some of my scopes is no impediment to their use. I ju...

Hi Don, any idea what the leaf is from?
I think I see a stoma in the first and third images, at the bottom, just right of center.

AO series 10 infinity scopes have their tube lens in the bottom of the head. I removed the head, screwed in a Leitz 10x 160 objective, got 50.4mm to m42 dovetail from RafCamera, and stacked a bellows and digital camera body on that. Whether it is still considered an infinity scope or whether this i...

Thanks for all the advice! It's still pretty overwhelming, but now I have a much broader range of brands/models to look for. One thing I've noticed is that the turret of most models would have to be removed (probably via hacksaw) as they'd get in the way, which doesn't sound like much fun. I suppos...

I have an AO Series 2 in similar shape as the one apochronaut mentioned that's in my boneyard, I would happily part with it as it's the only one of the series 2/4 line I have. I'm not certain if the 2 has the same capabilities as the 4 in the desired area, but a quick look suggests it's 1um fine fo...

Has anyone ever tried to concentrate a plankton collection sample with the use of a field centrifuge? I suspect I might get questioned by TSA as I try to re-enter the country with a few gallons of seawater.... I have no person experience, but I have read that centrifiging can cause significant dama...

The Reichert-Jung 63X - 0.80 - oo/0.17, is that an immersion objective?

:P Well, , let me know about it. I don't have one and you have peaked my interest. Greg Hiya I don't think it's anything to write home about but should be a step up from the Swift 380T, though is 20W halogen rather than LED. I'll post some pics etc Louise IMO, 20W is a fair bit of light. The 20W ha...

It seems the more I read about this the more I get confused... Why isn't there a straight answer to this question? Toilet paper? I would never use toilet paper, but is that because the purists convinced me that would be an awful idea or is there some truth to it? Is there an ideal solvent that work...

It was never clear to me is how the fraudulent Ebay seller hacked or stole a list of tracking numbers. Inside job in cahoots with a postal employee? Hacked a database - probably not all that secure in the early days of USPS tracking? Found some prolific shipper and got a list of their tracking numb...

I wonder if a sputter coating would work.

That was my assumption, not sure how else you'd do it without laying down too much and obliterating detail.

A schraeder seems a tad too large, so I think that's out of the running. I've got too many projects to get to the lathe (for starters, there's a car in front of it that needs to be fixed first), so it will be a while before I attempt anything there. In the meantime, I've begun modelling the wrench p...

I'm not a profesional, but I think it would depend on the materials one is handling. For a bit of pondwater, an insect, dust from the vacuum, spores, algae, and the other things we normally come into contact with during our lives, handwashing is likely sufficient. If you're working with more hazardo...

I'd be inclined to use a pair of 0.50 hex wrenches - tiny ones with screwdriver handles are readily available. They're actually easier to use than the push in wrenches with the push-back springs that get stuck. If you want to make something up yourself along the lines of the original, Schrader valv...
