This is the exact same image, all I've done is invert the second one. It's
interesting how this affects where the detail in the image can best be
seen.
We can see a lot more detail in this image than in the ones from GAO
(Glenlea Astronomical Observatory). We
can see that the galaxy spirals into the bulge whereas, in my image the
bulge appears much more round. We can also see more faint spiral arms as
well as an exention off the south of the smaller companion. These details
were more easilly picked up on this telescope because it is exactly five
times as large as the telescope at GAO, and so, all considered, our image
really isn't half bad.

Again, these images have a bit more detail than mine, but they still
compare fairly well, especially the red. The structure seen in my image
is about the same as in this red image, however the fainter regions here
are more visible. I think it is very possible that by obtaining another
ten or twenty minute exposure in the red at GAO, these images would be
comparable, especially if a log scale was used to display my image so the
bulge wouldn't be too washed out.

It's amazing the difference in resolution between the First Generation sky
survey (right) and the Second Generation (above)
This looks very much like the clear image I aquired. It doesn't capture
the central spiral structure either, though it does have better resolution
due to a smaller point spread function. The fact that my quality is so
comparable to this telescope is quite impressive considering ours is 40
cm as compared to their 48 inches That's more than twice as
large!!!
Not only that, being on a mountian they had a lot less atmosphere
above them to deal with aswell.
