Great photo. What brand did you buy?

Digital microscope, which one do you use?

 

Thanks Guys! Celestron Digital Microscope Pro

 

I was just checking amazon and seen this one for $39.95

Plugable USB 2.0 Digital Microscope with Flexible Arm Observation Stand for Windows, Mac, Linux (2MP, 10x-250x Magnification)

 

250X huh? Are you planning to use it to clip Lincoln's nasal hair?

lol

 

Ok laugh at the newbee

 

But I would get the last laugh if I could and did!

 

He who laughs last always laughs best! But, it's still your turn to buy the next round!

Was that picture taken with the built in light on the scope or your own lighting?

 

Built in

 

For digital microscopes, the "magnification" includes the ratio of the screen size to the sensor size in addition to the optical magnification. The optical mag on that image is about 2x, while the ratio of screen size to sensor size is about 30x, so the microscope would report a magnification of perhaps 60x for the image. A 250x magnification would then be more like 8x optical, which would zoom nicely in to see a good magnified view of the mintmark.

 

There's a sort of dirty little secret at play here with USB microscope "magnification." You measure that ultimate "magnification" with a ruler on your monitor screen, because it's counting the magnification from showing up on your monitor in the total.

My 2560x1440 screen would not offer as much "magnification" as a 1920x1080 screen (for a coin image 1080 pixels or smaller) because it'd be physically smaller on my screen than on the 1080. Unless, of course, that 1080 screen was down around 22-24" instead of my 27", at which point I would be getting more "magnification."

Think about it. As "250x magnification" a Mint Mark would be 10" wide. You're not getting "250x magnification."

 

That's cool!

 

I've been vetting various digital microscopes. Did you get the 5MP? Runs about $85?

 

That's the one

 

Thanks. I think for the $$$$ it's the best one out there.

 

Me too. I'm impressed so far
