Images From Other Telescopes


My Images
(Linear)

Filter= Indicated
FOV(Field of View)= 3.6x4.7 arcminutes

Image from the Arp Catalogue

Telescope=Palomar 200-inch (possibly with a Ross f/3.67 corrector lens)
Emullsion=103a-D (visual and blue wavelengths)
Seeing= 2
FOV= 3.7x2.9 arcminutes(Ned)

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.


Images from the Second Generation Sky Survey

Telescope="Data taken by ROE, AAO, and CalTech, Compression and distribution by Space Telescope Science Institute" (Skyview - More Info)
Emmulsion/Filter=Not found, though the image on the left hads the designation 'Blue' and the image on the right the designation 'Red'
FOV=4.0x4.0 arcminutes (specified in Skyview)
Seeing= Not found

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.

Image from the First Generation Sky Survey

Telescope=Palomar48-inchSchmidt (Ned)
Emmulsion=103aE (6450 Angstroms) (Ned)
FOV= 4.0x4.0 arcminutes (specified in Skyview)
Seeing=Not found

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.
