I am looking at the USB digital microscope eyepiece at

http://www.physlink.com/estore/cart/USBDigitalMicroscopeEyepiece.cfm

Someone on one of these lists recommended it.

It does not say how many megapixels.   Home Science Tools, where I bought
some microscope supplies recently, offers a very similar piece (may be the
same model) , for a similar price - and says it is 0.3 megapixels.   Or a
resolution of 640 x 480 pixels.

They offer another piece for several hundred dollars that is 1.3 megapixels,
or 1280 X 1024 megapixels.

In my experience, 1.3 megapixels in regular photography is plenty.   I have
my 3 or 4 megapixel digital camera set down as far as it will go.

However, for good photos of things under a microscope, don't you need high
resolution.   Is the 0.3 megapixel camera good enough, or do I need the 1.3
megapixel one?
