This picture of Hale-Bopp is a preliminary, unprocessed image. Only a 
routine dark subtraction has been done on the image.  North is at the 
top and east is to the left. 

The picture was taken at 6:01 A.M. on Tuesday, February 26th., four 
minutes later than the images Hale-Bopp #1 and Hale-Bopp #3.  During 
that time the camera stabilized at its normal operating temperature of 
-25 degrees centigrade.  The result is a smoother, cleaner picture. 

Though not readily apparent to the eye, careful measurements show that, 
compared to its position in the image Hale-Bopp #1, the nucleus of the 
comet has moved slightly.  Using the star at the bottom of the image as 
a reference, the nucleus of the comet has shifted one pixel north 
(towards the top) and two pixels east (towards the left).

The zoomed image is the same image enlarged by a factor of 2.
