Looking Good Joel,
I am use to eeking out electrical storms on Saturn, I have been supplying such data to a member of the Cassini RPWS team since Jan 2008.
I am accustomed to viewing the image from various angles and distances to try and identify structure. Ounce I found this feature in your image it became quite obvious.
Some points to consider with this matter.
The resolving power of an 11" scope, using Dawes Limit would be 4.56 / the aperture in inches. The result is expressed in arc sec's.
Therefore the theoretical resolution of your scope will be .4 of an arc sec.
The disk of Mars, on the night of your image was near enough to 8 arc sec's. The scale of your image on my screen is about 30mm pole to pole. Therefore 1 arc sec would represent 3.75mm across your image.
I am unsure of the angular size of Huygens for this night, however, what I find most compelling is that on my wall chart, the physical diameter of Huygens is very close to half the width of the Northern protrusion of Syritis Major.
Considering all of the above and relating the size of the feature that I detect in your image, it is not unreasonable to identify this feature as the Huygens Crater.
Regards
Trevor
