[AZ-Observing] More Mercury Photos

I'll add one of my Mercury transit shots to the many that have been 
posted.  I set up in the backyard and shot with my 90mm f/12 Ceragioli 
refractor and a Canon 20Da.  I have material to generate an animation as 
I had the camera shooting on a interval timer every 5min.  It will take 
a lot of work however as the mount was drifting without a proper polar 
alignment and I need to re-register them all.  I spent the afternoon 
making a pair of 22in elevation bearings and wondering over to the 
'scope every 15min to center up the Sun.
