Five images of the comet Hale-Bopp that I have taken this morning (8 Feb. 1997). First image: (4.08 UT 5 min exp.) has been processed with a log scaling; Second image: (4.21UT 8 min exp.) has been processed with a square root scaling; Third image: (4.21UT 8 min exp.) has been processed with a log scaling; Fourth image: (4.32UT 12 min exp.)has been processed with a square root scaling; Fifth image: (4.32UT 12 min exp.)has been processed with a square root scaling and have been introduced pseudocolors.

The bright star visible in the pictures (except first image) is Gamma Sge. The sky was clear, the comet was clearly naked-eye visible, near Gamma Sge. The field id about 30.7x20.6 Arcmin. To scale the images I have used a software done by me.
