It became increasingly clear that in order image the Polaris region with my Canon EF 200mm f/2.8L II USM that I would have to use an autoguider. There are of course several different ways to go about this, however, I wanted to make another easily removable, modular, stand-alone setup so I decided to build a bracket out of a leftover piece of an aluminum plate used to build my main scope gadget holder (

There is room to switch out the camera at a later date if I choose too. This bracket attaches to any dovetail type telescope mount but can also be attached directly to my telescope rings.
Test:
I did a preliminary test using the Ring Nebula region in Lyra. I used this because there was not anything bigger in my viewing window plus I was mainly interested on how the stars looked anyway. I was on this object for 30 minutes and with no drift and this is the most round the stars have ever looked using this lens so I think I am ready for some more interesting objects in the future. The image is was made with 21 x 45 sec subframes and what 30 minutes of processing can do.
