The following images are half linear dimensions of the original DC-120 images to save space and time downloading. The scale is big enough to just about see the faintest stars, but has the unfortunate effect of making it very much harder to spot single hot pixels because after JPEG compression they also look like stars.

Orion 19:24UT 15/1/98 16s Kodak DC-120 (best compression) sampled to 640x480 to save time on downloading. Single hot pixels are best examined on the original 1280x960 image in uncompressed mode. If you look carefully at this original image you can find quite a few CCD hot pixel stars. You can also see more structure in the corner glow effect as radial striations and colour fringes. Fortunately they are reproducible on every exposure so they disappear when the dark frame is subtracted leaving only the real stars. All stars down to 5th magnitude are fully recorded, and it becomes more patchy in the 5.3-5.8 magnitude range with some recorded and some not (presumably a colour bias).

Orion after dark frame subtraction - note the major cosmetic improvement of the corner glow at the expense of a slight increase in background noise by caused by subtracting the two images (approx 1.4 times that of a single image). The dark silhouette on the left is a tree which is considerably darker than my sky.
