Re: Recommendations for linear stage for use with 10x objective

Alison, you're getting good advice. The goniometer there, and others I saw in the forum, are quite pricey, and I'll probably just stick with my cut foam wedges for tilting my specimens. While I find a goniometric stage tremendously useful, they are, as you say, pricey. (My rig, The Bratcam , include...

Re: Anniversary: 7 years since joining PM.net

Steve, Seven really good years. When I look at your images, I always expect and see a display of meticulous craftsmanship and vision that is both distinctly individual and compelling. When I read your words, I find them thoughtful and informative. Thanks for all you've added so far. Here's hoping fo...

Re: Forum upgrade completed

I still have a couple of PMN forum tabs open from before the changeover, and can see what Elf is pointing out. (Clearly, the tab titles have gotten reversed--they used to place the name of the forum first, with details of the tab next. Now this formation is display in reverse order--and often trunca...

Re: Forum upgrade completed

Oh, don't mind me, I've been a curmudgeon since before I was two. When favorite magazines, newspapers, Websites, and fora have changed format, I've disliked the change in every single instance, without exception--so I was prepared to have my standard reaction to our very necessary forum upgrade. As ...

Re: Forum upgrade completed

I appear to have a phantom inbox notification that doesn't want to go away. Other than that I am digging it so far. I looked into this. . . . I also had such a phantom notification, but it went away when I clicked "Mark All Messages Read." As to the new look and feel, I echo Rik's "Hmph!" To me, th...

Macjack, welcome to the forum! :D I'm shooting with my lens focused at 1:1. I've included some test shots, the first is f/8, second is f/18. I have friends with similar setups who regularly shoot at f/8 and get fantastic results, so I'm completely lost. The only thing I can think is that perhaps foc...

Physicsmajor, Your images look good, and are evidence that the 2x Mitutoyo objective can make fine pictures. I also use this lens, and have often wondered why a few forum members dislike it. This said, every 2x Mitutoyo I've tested (perhaps 6-12 specimens?) shows a bit of transverse chromatic aberra...

You might check out item 192586530673 on eBay , and be aware of the search phrase "objective vials" (not entirely intuitive), which locates this and other listings. The shipping cost on these can be a bit high, so one may want to buy a number of vials to make it reasonable. Some time ago, I purchase...

If I am not wrong it is only possible to abort the shots with stackshot, now I think it would be a useful feature to be able to pause/resume also. Mete, I think you're right about this behavior of the StackShot, and that it would be a useful feature for the StackShot to include a pause/resume funct...

That is about as unethical as a lawyer sharing your case details with the opposition. I was hoping that such behaviour was not real but seems like I was mistaken. I agree--totally uncool. I do sympathize with the difficulty that small software vendors have in getting paid for their work, but this p...

You have surely thought of this, but is there any chance that the corruption issue started with the current version of DSLR Remote Pro? After all, 20,000 images is just over a dozen stacks at 1600 images per. In my experience, in this case, it is not the software. You have to write real crappy code...

If you could live with a 10mm diameter COB you should look at Yuji. 9W, 5600k, 98 cri. Although it is "self-serving" check out their website for some very good info on high CRI leds. (At this page: https://www.yujiintl.com/high-cri-led-lighting.html ) I've had these COBS on my electronics bench for...

JW, looks great! Thanks for posting your implementation. I like your replacement eyecup and contact cement approach. Batteries vs. wall power is probably a "to each his own" sort of choice. I started minimizing batteries in the studio because it used to seem like every time I was ready to shoot, I h...
