ST-7E Rotates in draw tube due to its weight

I have a ST-7Ei and am using it as an autoguider right now but will attempt imaging with it soon. I am troubled by the fact that the weight isn't centred at the nosepiece so the camera wants to rotate under the torque caused by the centre of gravity being off-set from the nose. For guiding it is best to have the camera oriented so that the east/west and north/south axes are lined up with the mount (G-11 in my case).
Are there brackets or some kind of jig that people use to hold their cameras still?

Thanks for any help you can provide.

Depending on which scope you are using we can give/sell you a threaded adapter to that scope and the ST7i.

Please contact the shop 800-850-2001 on Monday for the parts needed. You may be able to find them used here on AstroMart.

Thanks
