M31, Andromeda Galaxy. This is a 9x9 tiled mosaic that I built, IIRC there was something like 10 images per tile, plus flat field images and dark field images. So, something like 20 pictures per tile, 9 tiles, all slowly stitched together.
North American Nebula. Another 9x9 timed mosaic, but this time with closer to 30-40 pictures per tile, since each tile had several filters to image through.
NGC 4567/8, true color interacting galaxies:
M8, true color Triffid Nebula
I tended to over expose bright stars, because I was often using 20-40 inch telescopes. I preferred to blow out stars in return for fewer images. Technically, 1 10 minute image is cleaner (better signal to noise) than 10 one minute images stacked.
