Using the off the shelf MMOAG to SBIG-STL adapters I can't quite get the guide cam to focus via the MMOAG helical (borg) focuser - I have to use the shorter MMOAG push-pull drawtube connection. It is possible to move the prism up and down inside the MMOAG via spacers - with a 16803 chip though, you may not have so much room to move the prism. Otherwise, the MMOAG has been ideal and flexure free.

Yes that has been my problem with the MMOAG as well. I tried it on a Tak BRC250 after going through adapter hell but no joy with focus no matter what. I tried it on another scope and much the same. I was told there is a lens that you can fit in the focus tube to help it come to focus plus spacers to shift the MMOAG to the right spot.
I have this fun ahead of me when getting it all to work with the CDK.

Then get a regular guide cam for a guide scope for your woozy wide feild (yawn) stuff. For WFW, an external guide cam/scope is far more conveinient.

As much as I don't want I think I have to agree with you Fred.
There may be something wrong with it as the dark subtract makes the image go worse not better. A trip to SBIG coming up for it I think.
Once I get a 2nd autoguider and I can afford for it to be gone for a few weeks. Apart from these niggly things it is a good camera.
