[APML]: Beginner w/piggyback question

[James Funkhouser <jdfunkhouser@halnet.com>]

Hi,

 I am just starting into astrophotography.  So far my only attempts
have been some fixed-camera shots of Hyakutake, and some prime
focus photos of the recent lunar eclipse.

 I want to spend some time with piggyback photography before I try
to move into things more difficult.  I have all of the hardware I
need, but here's my (probably silly) question:  If I put my camera
onto the piggyback rail on my C5+, there is no way for me to adjust the 
tilt of the camera.  That is, I would like to be able to rotate the
camera in order to frame my shot a particular way.  Is there any sort
of adapter that will allow this, or should I just quit worrying about
it?
