JW, the reason you were given by Nikon in NY for the replacement of both the board and transformer is as follows. This base uses a 12V 50 W bulb. Most labs have 12V 100W bulbs around in drawers from other scopes that are common for them. When the 50 watt blows, guess what gets installed instead. The...

One needs to be astute on eBay. And let's face facts, this still is the market. I recently bought a Zeiss 16X multi immersion lens on eBay for $200. If that's too much for your hobby there is no hope. The risk is delamination with Zeiss objectives, but they're worth the hunt.

Beatsy, thank you for the insight. I agree that a microscope specific camera is too limiting for the price. Sony has kind of progressively upped their imaging game, as far as I have seen. I love the Canon software, but I think going forward, competing with a giant like Sony, who obviously has the re...

Well, several things about oil immersion. I does give the best resolution, but also causes the best specimen disruption on everything except fixed slides. With the multi immersion lenses, I've found that refractive index matching is where they excell. My issue with oil immersion stems from cover-sli...

Hi Beatsy, That looks pretty impressive. Do you own this camera, and if so, what , if any, other than the price, do you see as a drawback? Im holding out on full frame and still limping along with a cheapo Canon APS. This Sony is as expensive as a dedicated Nikon FF microscope camera ( with my emplo...

The pc board transistor or bridge rectifier, 99% of the time ... and where would the bridge rectifier be located in the image I posted. The square black thing with 4 wires on it between the fuse and transformer. Also, if one of the transistors on the pc board area is discolored from heat, it's bad....

Because that stage has a built in X and Y tension control on the knobs. You can make them so tight as to be unmovable.

Seriously? You drilled and tapped the Y scale indicator for a lock screw rather than adjusting the Y rack to resolve play in the table when moving the slide by hand?

Awesome chondrules, love those images!

The actual procedure or just the naming convention?
