Re: Objective-ly Confused Noob

So, cheapskate that I am, I didn't want to abandon my new too-short objectives. I found these super-cool little RMS-RMS adapters on ebay -- the black things -- they screw into the turret and the objective screws into the adapter. They come in a ton of different lengths. I bought a 9mm and a 10mm. On...

Re: Objective-ly Confused Noob

Thanks all! Luckily, I've only spent $12 or $15 or $18 at a time for "microscope stuff"......un-luckily, I've done it half-a-dozen times or so....oh, well. So now I'll be a bit more careful and buy a "195" objective or two (and no more, that's it, that all I need). (for now) And when I donate the Ko...

Objective-ly Confused Noob

I just bought my second junky second-hand microscope: an Accu-Scope 3004 (discontinued in 2010) which included a 4x and a 10X. So, I've been experimenting with swapping objectives with my Konus "College" (model 5302) and discovered that the A-S has a parfocal height of 45mm while the Konus has a par...

Re: Bino Head Retro-fit?

Thanks for the infos! I know from my telescopes that bino-vision helps A LOT to compensate for the floaters -- two eyes see slightly differing views and my big fat brain can filter out the stringy spirogyra-lookin' filaments. I un-screwed the 40mm-ish tube at the top (where the eyepiece fits) and my...

Bino Head Retro-fit?

Is it possible / practical to retro-fit a binocular head onto a compound microscope? I have a super-cheap Konus student model, and even at modest magnification my "floaters" are intrusive. Must the microscope be designed to accept a bino, or is there a standard as with objectives and eyepieces? What...

"Fixing" Old Slides??

I just picked-up my first halfway decent microscope at a second-hand store, a Konus 5302. It looked clean and complete (it was) and for $12 it was not a big financial decision. (I thought I would use it for building and repairing surface-mount circuit boards.....now I'll be on the lookout for a ster...
