[AZ-Observing] Re: Comet Holmes first look tonight

I am ready to assert that the star-like nucleus is offset to the east of center 
of the object as a whole.
  At 213x, I centered the nucleus in a crosshair box and turned off the drive.  
For 4 runs, it took 12 sec, 12 sec, 11 sec, 11 sec for the eastern edge of the 
outer sphere to reach the center. I then centered the western edge and turned 
off the clock drive. It took 13 sec, 13 sec, 13 sec, and 12 sec for the bright 
nucleus to reach the center. The drift time at this magnification on my scope 
is thus about 1 second longer from west to center than from center to east. 
Then, I lost interest and just gazed in amazement at this thing.

This isn't rocket science because there is some judgment about when the edge of 
the diffuse glow is clocked. However, it LOOKS to me like the bright core lies 
closer to the east side, so I am ready to believe the measurment, however 
primitive.

Let me know if anyone else is seeing an offset.

BTW:  Is it always this transparent and steady for 3 straight days around Full 
Moon? Can't remember setting up the scope around Full Moon in many a year.
