M 15

This globular cluster at the edge of the constellation Pegasus can be easily resolved on photographs taken with medium sized amateur telescopes. The center is overexposed on the print but still detailed on the negative. (cropped picture)

Date: 12 September 1999, 22.10h CET

Lens: f=1480 mm f/6.3

Guiding: manually with C5 at 139x

Exposure time: 30 minutes

Film: Kodak Royal Gold 400

Apparently I guided quite well at a magnification of "only" 139x. The stars are only slightly elliptical.
