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. The above image was obtained by applying a mathematical image processing algorithm to the original picture at the top of the page. The image has been processed using a rotational gradient filter, with rotation parameter 10 degrees and amplification factr 5.0
3. The image has been processed using an unsharp mask, with mask sigma set to 5.0.
