Re: Recommendations please now for or against nikon Z50

So I decided to check out the spec on the Z50 and particularly remote shutter cabling. . . . it does not have that port as far as I can see. I will continue to Google later. Ack! Good catch, John. I'm chagrined that I didn't notice this myself. But I'd never imagined that Nikon would leave out some...

Re: Recommendations please now for or against nikon Z50

John, I haven't had a Nikon Z50 in hand, but have been immersed in the Nikon world for decades, so I'll take a shot. I can't see any reason to avoid the Z50 if its specifications meet your needs. That is, if the Nikon APS-C sensor size (23.5 mm x 15.7 mm) is a good fit for your microscope setup, and...

Re: How good are alternatives (clones) to Mitutoyo lenses

(my computer's of an advanced age, and prone to near-overheating :lol: ) I've fixed a lot of Windows machines, only rarely Macs, and never an iMac. But my guess is your near-overheating is caused either by internal heat sinks being clogged by dust, or by those heat sinks needing better thermal cond...

Re: Hello I'm New

Welcome aboard, CrispyMacro! :D I don't know what your subject interests are for macro, but given your hardware, you might find a dedicated macro lens very helpful. I recall how much easier things became when I got my first dedicated macro lens, as compared with using the macro range of a zoom. A ni...

Re: How good are alternatives (clones) to Mitutoyo lenses

Sorry, I couldn't resist! :D You certainly haven't put your foot in anything. I was mainly razzing Rik. I'd suggest you download both programs, using their free trials, and see which you like best. As for ease of use, the Zerene Stacker support pages have very good tutorials. I haven't looked at Hel...

Re: How good are alternatives (clones) to Mitutoyo lenses

Excellent advice, thank you Chris and Rik! I forgot to mention that I still haven't purchased an image-stacking software license, and I'm thinking of going with Helicon Focus (Zerene looks nice, too, but I've seen more mentioned use of the former in research publications). I find irony in the above...

Re: How good are alternatives (clones) to Mitutoyo lenses

The reason I went for the mitty 5x is that I read a post here (I think Chris S. wrote it) about a 50x mitty and it performed so well even though it had a large ding on the front element. Yes, it was I, and there were four dings in the front element! Here was that post: Mitutoyo 50x with chips in gl...

Re: How good are alternatives (clones) to Mitutoyo lenses

Also, I've wondered about Lightglass Optics, as I looked at their site in past months when I began my search, but I couldn't find any BBB reviews, and I thought it disconcerting that they mentioned their Customer Service availability is somewhat limited; Lightglass Optics’ customer service is fine....

Re: How good are alternatives (clones) to Mitutoyo lenses

If I end up getting a used Mitutoyo 5x objective, do you think I'd be safe in assuming it's been previously disassembled if it has noticeable CA when used with my 100mm and 200mm Pentax telephoto lenses? As a hobbyist, my budget is absolutely abysmal, so I can't possibly afford a new Mitutoyo, much...

Re: WTB Focus Block or Rig

John, If no one can supply you with what you need immediately, or if you can afford to wait until the winter months, I should be able to supply you with something very nice. I've collected a number of microscope stands with good focus blocks, which are currently stored on shelves awaiting transforma...

Re: Windows XP HELP!

I still have a couple of Windows XP machines in use, mostly offline, supporting devices that have been running nicely with them for years. Since they work, I see no reason to bother with a newer operating system for those machines. This said, if I fire up my old Nikon film scanner again, I'll try it...

Re: First Post photos and questions about Magnification

Jon, welcome to the forum! :D I feel like I almost cut my eye on your last image. And the surface texture shown in all the images is striking. I echo Rik's praise of your lighting. Lighting is critical for your choice of subject, and you did a great job. Your Nikon 40x/0.5 ELWD 210/0 is a classic ob...

Re: Playing With Step Motor

That's a good and useful video, Peter.

I also second your advice in another thread that if one wishes to get a sense of stepper motors, it's a good idea to just get a stepper and constructively play with it.

Re: Question on tube length and focus

John, For your purposes, you can treat all the images you showed as demonstrating that your tube lens is at an appropriate distance from your sensor. Even if your assembly is theoretically 1.5mm too short, don't worry about it. What you have right now is good to go. Having the tube lens at the preci...

Re: White Snakeroot

On occasions when I see white snakeroot ( Ageratina altissima ) in the wild, I find it interesting because of its history, including its being the likely cause of death for the mother of an American president. But for snakeroot to kill Nancy Hanks Lincoln, it had to first get eaten in quantity by a ...
