    I was miss informed.

    I was miss-informed. I thought he was doing a PhD in astrophysics.

    Can anyone tell me what Mike does to make a living these days ?
  2. I am pretyty sure

    I am pretty sure someone made what they called upie downie flags. Read about them on this site somewhere. I guess the idea never took off. No pun intended. May be now they will.

    I put it back

    What one man can do another can undo. I add the nitrobenzene back to the hoppes at the same concentration. But before you ask I can't tell you where I got it from.

    For carbon

    For carbon I have always used carbon tetrachloride. Not sure if you can still buy it. It's very efficient but you need to be careful of the fumes and skin contact.

    Oh brother

    Oh brother. I am sure there have been plenty of papers written on the subjects you query. So perhaps hit the web. Read them and get back to me in say in a few months. Otherwise this could turn into a...

    This is with good glass.

    I chit you not on the glass. Glass can beat power.

    Good air

    The more power you dial up the better the air has to be in order to make use of it. It's the same when shooting a camera with a telephoto on it. The best lens can produce lousy images when the air is...

    For many years I used a zeiss endoscope system. I had to because things called borescopes like the hawk didn't exist. This device was and still is over the top for what I ask it to do. In the late...

    Yeah I wonder also
