Mirror#1.gif is a pair of small images (Zoomed with xv) of my mirror. These images were taken with an Electrim EDC-1000 CCD camera and a short lens.
These images were originally 90 x 90 (Or so)
The leftmost image is a single 16 millisecond frame The right image is an average of 50 frames.
Mirror#3.gif is after a further 1 hour of polishing with a longer stroke This image was taken using a lens forcibly extracted from an old GAF 8mm movie camera I got for $5.00 at the local junk shop.
This lens is a zoom lens, so I can change the image scale.
This image is almost 165 x 192 (And I had xv double it)
The lens had two prism devices in the light path. One is to extract a beam that hits a photo-diode to do automatic exposure control. The second one extracts another beam that is used for the through-the-lens viewing feature.
When this image was taken, I had only discovered, and removed one of the two prism devices. The remaining device caused the diagonal line, and the circular rings.
The CCD array window also had gunk on it that caused a few small blotches.
I have since removed the second prism, and cleaned everything and I am getting much better images.
The mirror is still not polished out to the edge, and that is causing the gigantic turned down edge (I hope).
I'll continue to polish, and let you know what happens.
I'll also write some code to compare the left and right hand zones and beep when they darken at the same time.
