"Wednesday for Comet Machholz"

        The above appeared as the subject line in an e-mail from my club's Yahoo! Groups group called ovas1. As luck would have it: I wasn't working and it was cold and clear. So I headed up the hill to join David Tolley,  Jeff Ball (as seen in Sky and Telescope and at the Laurel Highlands Star Cruise and at many OVAS and one AAAP (hosts of the LHSC) meeting(s)),  Melissa (sorry I don't know your last name), and  Brent Maynard (best modified web cam planet imager in our club) at the Donald C. Martin Observatory.

        Jeff was piggy back imaging on the Losmondy rail attached to the club's C-14. I, with my ignorance of image scale and all was imaging through the C-14 with a f 3 reducer and a Stellacam II. There was much comedy as Jeff and I "shared" the scope. I do believe that a "c" mount lens and piggy backing the Stellacam II would have been a better method.

            The first set  was made by adding 10-20 set of 8.533 second images  with AstroVideo. the images were added on the fly. Gain was set at 60% (first big tic past half way) and the gamma was set to lo (low). The second set was 10-20, 8.533 second images added on the fly with the gain at 70% (two tics past half way) and the gamma at no (off).

                As you see, I could discern no tail.
