Hale Bopp

 
September 29, 1997 
09:50-10:20 UT

1. 8 separate 30 second images and 30 separate 45 second images of Hale Bopp have been flat fielded and combined to create this image. The image was obtained using a 12 inch Maksutov with 1524mm focal length and no filter. Image is 31.1 by 20.7 arc minutes. This is an integrated white light image. First image started at 05:50 EST with the last image started at 06:20. Stars look trailed in this composite image, since it was effectively guided on the comet's motion. 

2. This image was obtained by applying a mathematical image processing algorithm to the original picture (1). The image has been processed using a rotational gradient filter, with rotation parameter 10 degrees and amplification factor 5.0.

2. 21 separate 50 second images and 37 separate 30 second images of Hale Bopp have been flat fielded and combined to create this image.

This movie is an animated gif, constructed from 9 40 second images taken every 5 minutes on the morning of 16 September 1997. The motion of the comet, and thin clouds can be seen.

29 40 second images of Hale Bopp have been flat fielded and combined to create this false-colorized image. Field of view is approximately 0.3 degrees by 0.2 degrees. The original composite image has been logarithmically scaled, unsharped masked and false-colorized to reveal structure using Mira. Note the linear features. Stars look trailed in this composite image, since it was effectively guided on the comet's motion. 

43 30 second images of Hale Bopp have been flat fielded and combined to create this false-colorized image. Field of view is approximately 0.3 degrees by 0.2 degrees. The same image has been magnified below by a factor 2 and false-colorized to reveal structure. Note the linear feature to bottom right. Stars look trailed in this composite image, since it was effectively guided on the comet's motion. 

19 30 second images of Hale Bopp have been flat fielded and combined to create this false-colorized image. The same image has been magnified below.
