Location of Photo:

My driveway near De Soto, Kansas.

01:16 UT, 10-28-07


This is a 1 minute exposure with a Hutech-modified Canon Rebel XTi used prime focus on my home-made 6" f/8 reflector, ISO 800. The color image was saturated in Picasa2 software, and converted to green-filtered B&W which shows the outer gas coma. . . and it is not quite centered on the inner coma.


This image shows the outer gas coma of 17P/Holmes as being more than twice the dia. of the bright, inner coma.
